Answer:
x = cost of each gift basket = $14.5
y = one time delivery fee = $135
Step-by-step explanation:
Let
x = cost of each gift basket
y = one time delivery fee
40x + y = 715 (1)
400x + y = 5935 (2)
Subtract (1) from (2)
400x - 40x = 5935 - 715
360x = 5220
x = 5220/360
x = 14.5
Substitute x = 14.5 into (1)
40x + y = 715 (1)
40(14.5) + y = 715
580 + y = 715
y = 715 - 580
y = 135
x = cost of each gift basket = $14.5
y = one time delivery fee = $135
x + 4 + 2x + 5 what will be simplified expression
Answer:
3x + 9
Step-by-step explanation:
1. combine like terms
x and 2x = 3x
4 + 5 = 9
2. put them together
3x + 9 is your answer.
Hope I helped! have a wonderful day!
Answer:
3x + 9
Step-by-step explanation:
Just add the both the x's together:
2x + x = 3x
Then add the regular numbers together:
4 + 5 = 9
then put the answers together:
3x + 9
Can someone please help me this?
Answer:
Yes
Step-by-step explanation:
We can make one equation other to the other to solve for x-value first;
=> -4x = x - 5
=> -4x + (-x) = -5
=> -5x = -5
=> x = -5/-5
=> x = 1
Once we have the x-value we can substitute it in for "x" in any equation to find the y-value;
=> y = x - 5
=> y = (1) - 5
=> y = -4
Writing the answer coordinate points would look like (x, y) which would be (1, -4) which is similar to the give, there for yes the solution to the equations is the given coordinate.
Hope this helps!

Answer:
Step-by-step explanation:
The intersection point (centroid) divides the medians in ratio 2:1. it does mean that the long segment value is the short segment value multiplied by two. let's call the centroid point G.
BG=DG*2=4*2=8
CG=EG*2=2*2=4
AG=FG*2 =>FG=AG/2=6/2=3

Answer:
Volume of the pyramid is 448 cubic meters.
Step-by-step explanation:
Volume of the given pyramid = [tex]\frac{1}{3}(\text{Area of the rectangular base})(\text{Height of the pyramid})[/tex]
Area of the rectangular base = Length × Width
= 12 × 16
= 192 m²
Volume of the pyramid = [tex]\frac{1}{3}(192)(7)[/tex]
= 448 m³
Therefore, the volume is 448 cubic meters.

Theresa wants to order her mother flowers for her birthday. She wants to give the delivery person a $6.00 tip. The cost of the flowers was $75. How much should she tip the driver.
Answer:
[tex]8\%[/tex]
Step-by-step explanation:
Since question already gives the number of dollars she will tip, I'm assuming it's asking for percent tipped.
Because the total is $75 and Theresa is tipping $6, she is tipping [tex]\frac{6}{75}=0.08[/tex] of the total. To convert this to a percentage, multiply by 100: [tex]0.08\implies 0.08\cdot 100=\boxed{8\%}[/tex]
Determine whether the lines given by the fallowing equations intersect at (-1/4,3/4) show all work. 4x+8y=5, x-3y= -3
Answer:
(0, 1)
Step-by-step explanation:
First, we need to make y the subject of the formula from both expressions
For 4x+8y=5
8y = 5- 4x
y = (5-4x)/5
Similarly for x-3y= -3
-3y = -3 - x
3y = x+3
y = (x+3)/3
Since both lines intersects, hence;
(5-4x)/5 = (x+3)/3
Cross multiply
5(x+3) = 3(5-4x)
5x + 15 = 15 - 12x
5x + 12x = 15 - 15
17x = 0
x = 0/17
x = 0
Sustitute x = 0 into any of the equations
Given that y = x+3/3
y = 0+3/3
y = 3/3
y = 1
This shows that the lines intesects at (0, 1)

7.5cm2
Step-by-step explanation:
5x3cm=15cm2 because of base x height/2 you would do
15cm2 divided by 2 since it is a triangle (a half of a square) which is 7.5cm2
Answer:
D.
Step-by-step explanation:
Area of a triangle is bh/2
So your base is 5 and your height is 3.
So you do 5*3 which is 15.
And lastly you do 15/2, which is 7.5. 7*2 is 14, and 8*2 is 16
So 7.5 times 2 is 15

April measured her bed and made a scale drawing. The scale of the drawing was 1
centimeter = 6 inches. In the drawing, the bed is 10 centimeters long. What is the
length of the actual bed?
Answer:
60 inches
Step-by-step explanation:
Given data
We have the scale of the drawing as
1cm= 6 inches
Now if 1 cm is equivalent to 6inches
then 10cm will be x inches
Cross multiply we have
x*1= 10*6
x= 60 inches
Hence the length of the actual bed is 60inches

A.)90
B.)41
C.)15
D.)83
Answer:
D
Step-by-step explanation:
∠ABC= ∠DBE (vert. opp. ∠s)
(6x -7)°= (4x +23)°
6x -7= 4x +23
Being x terms to 1 side, constant to the other:
6x -4x= 23 +7
Simplify:
2x= 30
Divide both sides by 2:
x= 15
Substituting the value of x:
m∠ABC
= 6(15) -7
= 83
Find the area of the shape below
Answer:
Q1) 104m²
Q2) 121 in.²
Step-by-step explanation:
Q1)
GIVEN :-
Figure given in the question comprises of a triangle & a rectangle.Length of the rectangle = 10 mWidth of the rectangle = 8 m Base of the triangle = 8 mHeight of the triangle = 6 mTO FIND :-
Area of the figureGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
For a triangle with height 'h' & base 'b' , its area = [tex]\frac{1}{2} \times b \times h[/tex].For a rectangle with length 'l' & width 'w' , its area = [tex]l \times w[/tex]SOLUTION :-
Area of the triangle = [tex]\frac{1}{2} \times 8 \times 6 = 24m^2[/tex]
Area of the rectangle = [tex]10 \times 8 = 80m^2[/tex]
Area of the figure = (Area of the triangle) + (Area of the rectangle)

help please , i need the perimeter and area
Answer:
Area = 3.5325 ft² ≈ 3.53 ft²
Perimeter = 7.71 ft
Step-by-step explanation:
This is a semi-circle so we just divide the circumference of the original circle by 2
C = 2πr
C = 2 * 3.14 * 1.5
C = 3.14 * 3
C = 9.42
9.42 / 2 = 4.5 + 0.21 = 4.71 ft
4.71 ft + 3 = 7.71 ft
Area:
A = πr²
A = 3.14 * 2.25
A = 7.065 ft²
7.065 ft² = 3.5 + 0.0325 = 3.5325 ft²

sutract
-2/8 from 4/5
4/5-(-2/8)= 4/5+2/8 On taking LCM = 42/40= 21/20
⚠️❗️⚠️❗️⚠️❗️ 10 POINTS what's the area
Answer:
263(usually it would say cm or m)²
Step-by-step explanation:
area = l x w
l= 25
w= 19
25 x 19 = 551
thats the area without subtracting the missing area's.
missing area= 9 x 16
=144
since theres 2 areas missing, times it by two
144 x 2
=288
subtract the missing area from the total because its not there.
551 - 288
= 263
The line x = k intersects the graph of the parabola x = -2y^2 - 3y + 5 at exactly one point. What is k? Thank you! :)
Answer:
49/8 is the value of k
Step-by-step explanation:
We have the system
x = -2y^2 - 3y + 5
x=k
We want to find k such that the system intersects once.
If we substitute the second into the first giving us k=-2y^2-3y+5 we should see we have a quadratic equation in terms of variable y.
This equation has one solution when it's discriminant is 0.
Let's first rewrite the equation in standard form.
Subtracting k on both sides gives
0=-2y^2-3y+5-k
The discriminant can be found by evaluating
b^2-4ac.
Upon comparing 0=-2y^2-3y+5-k to 0=ax^2+bx+c, we see that
a=-2, b=-3, and c=5-k.
So we want to solve the following equation for k:
(-3)^2-4(-2)(5-k)=0
9+8(5-k)=0
Distribute:
9+40-8k=0
49-8k=0
Add 8k on both sides:
49=8k
Divide both sides by 8"
49/8=k

You choose a marble at random from a bag containing 12 red, 12 blue, 4 green, 6 yellow, and 26 black
marbles,
The marble is red
Answer:
12+12+4+6+26=50
12/50=6/25=0.24=24%
Answer:
1/5.
Step-by-step explanation:
First you have to add up all of the numbers: 12+12+4+6+26. Then you have to find how many red marbles there are, which this case there are 12, so you get your fraction of 12/60 which can be reduced to 1/5.
