Answer:
Four tickets and four snacks comes to a total of $74.00
If she buys x snacks, that cost is 4.50x. so the total for 4 tickets and unknown snacks is 4(14) + 4.5x
Step-by-step explanation:
Nicole + 3 kids is 4 tickets times $14. 4×14=56. Add the snacks. 4×4.50=18. $56+$18=$74
16. Construct 3 equations starting with x = 5.
TO FIND: construct 3 equation starting with x=5?
SOLUTION:
The equation is in the form of variable and constant equating.
Let the equation be x=5.
TO CREATE AN EQUATION,
FIRST WE ADD 5 BOTH SIDe,
x + 5=5+5
=x + 5=10
SECOND WE SUBRACT 5 BOTH SIDE,
x — 5=5—5
=x—5=0
THIRD WE MULTIPLY 5 BOTH SIDE,
5x=5×5
=5x=25

Which ordered pairs make the open sentence true?
5x- y > 12
Select all the correct answers.
(3, 4)
(4, 9)
(1, – 8)
- (0, – 10)
(-1, – 17
Answer:
(1, -8)
Step-by-step explanation:
5(1) - (-8) = 5 + 8
= 13.
An ordered pair is represented by (x,y). The ordered pair that makes the sentence 5x- y > 12, true is (1,-8)
Given that:
[tex]5x - y > 12[/tex]
First, we test each option
[tex](a)\ (3,4)[/tex]
So, we have:
[tex]5 \times 3 - 4 > 12[/tex]
[tex]15 - 4 > 12[/tex]
[tex]11 > 12[/tex] ---- This is false
[tex](b)\ (4,9)[/tex]
So, we have:
[tex]5 \times 4 - 9 > 12[/tex]
[tex]20 - 9 > 12[/tex]
[tex]11> 12[/tex] --- This is false
[tex](c)\ (1,-8)[/tex]
So, we have:
[tex]5 \times 1 --8 > 12[/tex]
[tex]5 +8 > 12[/tex]
[tex]13 > 12[/tex] --- This is true
[tex](d)\ (0,-10)[/tex]
So, we have:
[tex]5 \times 0--10 > 12[/tex]
[tex]0+10>12[/tex]
[tex]10>12[/tex] ---- This is false
[tex](e)\ (-1,-17)[/tex]
So, we have:
[tex]5 \times -1 --17 > 12[/tex]
[tex]-5 +17 > 12[/tex]
[tex]12 > 12[/tex] --- This is false
Hence, the ordered pair that makes [tex]5x - y > 12[/tex], true is: [tex](c)\ (1,-8)[/tex]

greater than 1
Answer:
less than 1
Step-by-step explanation:
True or False? If false, explain why? All whole numbers are natural numbers.
Answer:It depends, many people do count 0 as a natural number, but MOST do not.
So for most HS text book, the answer is NO, all whole numbers are not natural numbers and the reason is 0 is a whole number but not a natural number.
Answer:
false
Step-by-step explanation:
because the set of whole numbers starts from 0 whereas the set of natural numbers starts from 1 and so on
Plot point C(2,7). If M is the midpoint of CD , what are the coordinates of D?
Answer:
The coordinates of D is (-4,-9)
Step-by-step explanation:
Given
C = (2,7)
M=(-1,-1) ----- Missing part of question
Required
Determine the coordinates of D
Let the coordinates of D be (x₂,y₂)
We'll solve this question using mid point formula;
[tex]M(x,y) = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Where
[tex]C(x_1,y_1) = (2,7)[/tex] and [tex]M(x,y) = (-1,-1)[/tex]
Put these values in the formula
[tex](-1,-1) = (\frac{2+x_2}{2},\frac{7+y_2}{2})[/tex]
By comparison;
[tex]-1 = \frac{2+x_2}{2}[/tex] and [tex]-1 = \frac{7+y_2}{2}[/tex]
[tex]-1 = \frac{2+x_2}{2}[/tex]
Multiply both sides by 2
[tex]-2 = 2 + x_2[/tex]
Subtract 2 from both sides
[tex]-2 -2 = x_2[/tex]
[tex]x_2 = -4[/tex]
[tex]-1 = \frac{7+y_2}{2}[/tex]
Multiply both sides by 2
[tex]-2 = 7 + y_2[/tex]
Subtract 7 from both sides
[tex]-2 - 7 = y_2[/tex]
[tex]y_2 = -9[/tex]
Hence, the coordinates of D is (-4,-9)

What is the formula for the volume of a cylinder
Solve the equation
7x25=30
Answer:
x = -(-30/7)^(1/25) or x = (30/7)^(1/25) or x = (-1)^(2/25) (30/7)^(1/25) or x = -(-1)^(3/25) (30/7)^(1/25) or x = (-1)^(4/25) (30/7)^(1/25) or x = -(-1)^(1/5) (30/7)^(1/25) or x = (-1)^(6/25) (30/7)^(1/25) or x = -(-1)^(7/25) (30/7)^(1/25) or x = (-1)^(8/25) (30/7)^(1/25) or x = -(-1)^(9/25) (30/7)^(1/25) or x = (-1)^(2/5) (30/7)^(1/25) or x = -(-1)^(11/25) (30/7)^(1/25) or x = (-1)^(12/25) (30/7)^(1/25) or x = -(-1)^(13/25) (30/7)^(1/25) or x = (-1)^(14/25) (30/7)^(1/25) or x = -(-1)^(3/5) (30/7)^(1/25) or x = (-1)^(16/25) (30/7)^(1/25) or x = -(-1)^(17/25) (30/7)^(1/25) or x = (-1)^(18/25) (30/7)^(1/25) or x = -(-1)^(19/25) (30/7)^(1/25) or x = (-1)^(4/5) (30/7)^(1/25) or x = -(-1)^(21/25) (30/7)^(1/25) or x = (-1)^(22/25) (30/7)^(1/25) or x = -(-1)^(23/25) (30/7)^(1/25) or x = (-1)^(24/25) (30/7)^(1/25)
Step-by-step explanation:
Solve for x:
7 x^25 = 30
Hint: | Divide by an appropriate factor to make the coefficient of x^25 equal to 1.
Divide both sides by 7:
x^25 = 30/7
Hint: | Take 25^th roots of both sides.
Taking 25^th roots gives (30/7)^(1/25) times the 25^th roots of unity:
Answer: x = -(-30/7)^(1/25) or x = (30/7)^(1/25) or x = (-1)^(2/25) (30/7)^(1/25) or x = -(-1)^(3/25) (30/7)^(1/25) or x = (-1)^(4/25) (30/7)^(1/25) or x = -(-1)^(1/5) (30/7)^(1/25) or x = (-1)^(6/25) (30/7)^(1/25) or x = -(-1)^(7/25) (30/7)^(1/25) or x = (-1)^(8/25) (30/7)^(1/25) or x = -(-1)^(9/25) (30/7)^(1/25) or x = (-1)^(2/5) (30/7)^(1/25) or x = -(-1)^(11/25) (30/7)^(1/25) or x = (-1)^(12/25) (30/7)^(1/25) or x = -(-1)^(13/25) (30/7)^(1/25) or x = (-1)^(14/25) (30/7)^(1/25) or x = -(-1)^(3/5) (30/7)^(1/25) or x = (-1)^(16/25) (30/7)^(1/25) or x = -(-1)^(17/25) (30/7)^(1/25) or x = (-1)^(18/25) (30/7)^(1/25) or x = -(-1)^(19/25) (30/7)^(1/25) or x = (-1)^(4/5) (30/7)^(1/25) or x = -(-1)^(21/25) (30/7)^(1/25) or x = (-1)^(22/25) (30/7)^(1/25) or x = -(-1)^(23/25) (30/7)^(1/25) or x = (-1)^(24/25) (30/7)^(1/25)
For what value of the variable will the expression 8b−27 be equal to the following:
5
Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE

Charmaine works mowing lawns and babysitting. She earns $8.80 an hour for mowing and $8.10 an hour for babysitting. How much will she earn for 6 hours of mowing and 1 hour of babysitting?
Answer:
Charmaine earns $60.90 for 6h for mowing and 1h for babysitting.
Step-by-step explanation:
We must write the data problems.
Charmaine = $8.80/h mowing
Charmaine = $8.10/h babysitting
How much will Charmaine earn for 6 h mowing and 1 h babysitting?
1 h mowing ....................... $8.80
6 h mowing ....................... $x
x = 6 h mowing * $8.80
x = $52,8
To find the total earn of Charmaine, we have to gather the earns from mowing and babysitting.
$52,8 (from mowing) + $8.10 (from babysitting) = $60.90

Jim is twice as old as his sister. If s isthe sister's age, what is the sum of their ages?
Answer:
3s
Step-by-step explanation:
Given:
Jim is twice as old as his sister.
His sister's age is signified by the variable s.
∴ Jim's age is 2s.
You are trying to find the sum of both their ages, or add them together:
2s + s
Simplify. Combine like terms:
2s + s = 3s
3s is the expression you will use to find the sum of their ages.

the base of a triangle is 3.4cm.the area is 20.74cm.find the height to 1 dp
Answer:
12.2 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 20.74 and b = 3.4 , thus
[tex]\frac{1}{2}[/tex] × 3.4 × h = 20.74 ( multiply both sides by 2 to clear the fraction )
3.4h = 41.48 ( divide both sides by 3.4 )
h = 12.2 cm
h = 12,2 cm
Step-by-step explanation:Area formula
A = b×h/2
20.74 = 3.4×h/2
41.48 = 3.4h
h = 41.48/3.4
h = 12,2 cm

Write the equation for a line in slope-intercept form (y=mx+b) that
is parallel to y = -2x + 3 and passes through the point (-3,5).
Answer:
y = -2x - 1
Step-by-step explanation:
Parallel lines have the same slope, so the slope will also be -2.
Plug this slope and the given point into the equation y = mx + b and solve for b:
y = mx + b
5 = -2(-3) + b
5 = 6 + b
-1 = b
Then, plug this and the slope into the equation:
y = -2x -1 will be the equation
Brody’s family took a road trip to the Grand Canyon. Brody fell asleep 65% of the way through the trip. If 35 sleep after they have travel 390 miles, what was the total length of the trip?
Answer:
Total length of the trip = 600 miles
Step-by-step explanation:
Given:
Distance travel during sleep = 65%
Distance travel during sleep = 390 miles
Find:
Total length of the trip
Computation:
Total length of the trip = Distance travel during sleep [100 / 65]
Total length of the trip = 390 [100 / 65]
Total length of the trip = 600 miles

which expression is equivalent to 1.5(6x+3y)+2x-0.05y?
A.11x+4.45y
B.11x+5y
C.11x+2.95y
D.9.5x+4y
Answer:
The correct option is (a).
Step-by-step explanation:
We need to find the expression that is equivalent to 1.5(6x+3y)+2x-0.05y.
Firstly opening brackets as follows :
[tex]1.5(6x+3y)+2x-0.05y=1.5\times 6x+1.5\times 3y+2x-0.05y\\\\=9x+4.5y+2x-0.05y[/tex]
Now taking x terms and y terms together
[tex]9x+4.5y+2x-0.05y=(9x+2x)+(4.5y-0.05y)\\\\=11x+4.45y[/tex]
So, 1.5(6x+3y)+2x-0.05y is equal to 11x+4.45y.
