Answer: p= $8 s= $2.50
Step-by-step explanation:
3p + 4s = 34 and 3p + 7s= 41.50
Since the number of pizzas DIDNT change between these two equations, we can use the total of the second equation to help us find the price of one sandwich.
41.50 - 34 = $7.5 for 3 sandwiches (7s-4s)
So how much is one sandwich? 7.50/3 = $2.50 for each sandwich
now that we know s, it’ll be much easier finding p. We can use one equation to find p.
3p + 4(2.5) = 34 (Solve algebraically)
3p + 10 = 34
- 10 | -10
3p = 24
3p/3 = 24/3
p = $8. Now you can check by substituting the variables!
if the edges of a cube are 6 inch edges. What is the volume?
Answer:
Volume = 216
Step-by-step explanation:
Answer:
216 in³
Step-by-step explanation:
volume of a cube = [tex]a^{3}[/tex]
a = 6
[tex]a^{3} = 6^{3}[/tex]
[tex]6^{3}[/tex] or 6 x 6 x 6 = 216

Answer:
y = 2x + 2
Step-by-step explanation:
First you want to find the slope of the line that these coordinates make. To do this, use the slope formula: (y₂ - y₁) / (x₂ - x₁). I will use the first and last points.
(0, 2) & (6, 14)
Plug in these values:
(14 - 2) / (6 - 0)
Simplify the parentheses.
= (12) / (6)
Simplify the fraction.
12/6
= 2
This is your slope.
Now plug this into the standard slope-intercept equation: y = mx + b
y = 2x + b
b is the y-intercept, or the value of y when x = 0. If y=we look at the table, we can see that when x = 0, y = 2.
Therefore, our b-value is 2.
Plug this into our equation.
y = 2x + 2

Find the value of this expression
(50 - 2) ÷ 4 - 7²
-40
-41
-37
Answer:
The answer is -37.
Step-by-step explanation:
1) Simplify 50-2 to 48.
48 ÷ 4 - [tex]7^{2}[/tex]
2) Simplify [tex]7^{2}[/tex] to 49.
48 ÷ 4 - 49
3) Simplify 48 ÷ 4 to 12.
[tex]12 - 49[/tex]
4) Simplify.
[tex]-37[/tex]
Therefor, the answer is Option C) -37.
Three friends were playing a game of marbles. At the end of the game, Marcy had 25% of the marbles, Roger had21of the marbles, and Ann had the rest of the marbles. If there were 100marbles altogether, how many marbles did Ann have at the end of the game
Answer:
54
Step-by-step explanation:
total no. of marbles=100
no. of marbles Marcy had
=25% of 100
=25/100×100
=25
no. of marbles Roger had=21
Let the no. of marbles Ann had=x.
So, 25+21+x=100
46+x=100
x=100-46=54
Therefore, Ann had 54 marbles at the end of the game.

If you graph these two, the point where the two lines intersect is (1,4).
Answer:
Tell me if this works...
Step-by-step explanation:
The solution is basically the point where the lines intercept so you could try (1,4) and (5,0) for the first line and (1,4) and (-5,0)

A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25, point, 25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.

(Choice A)
A
Slope and xxx-intercept
(Choice B)
B
Slope and y-intercept
(Choice C)
C
Slope and a point that is not an intercept
(Choice D)
D
x-intercept and y-intercept
(Choice E)

PLEASE HELP !!!!!!!
(Answer is not -3)
Answer:
Look below.
Step-by-step explanation:
K(x)=x^2 isnt graphed but P(x)=x^2+n is. We could use this information to figure out what n is. In a quadratic function we always have the same points unless we are transforming it.
X Y
2 4
1 1
0 0
-1 1
-2 4
If we compare what the points were in the parent function to what is shown now we could see that the graph went down 6. From this information we can conclude that n must be -6.

R
Towns P, Q and Rare connected by roads PQ, PR and QR.
PR is 15 km longer than PQ.
QR is three times as long as PR.
The total length of the three roads is 245 km
Work out the length of PQ.
Use x as the unknown in any working.
Your final line must say, PQ = ...
Pa
Answer: 37 km
Step-by-step explanation:
Given
The total length of the three roads is 245 km
Suppose the length of PQ is [tex]x\ km[/tex]
According to question
The Length of PR is [tex]x+15[/tex]
The length of QR is [tex]3(x+15)[/tex]
The Sum of PQ, PR, and QR is
[tex]\Rightarrow x+x+15+3(x+15)=245\\\Rightarrow 5x+60=245\\\Rightarrow 5x=185\\\Rightarrow x=37 km[/tex]
length of PQ=37 km

Secant AD and AE intersect in the exterior of a circle. ∠ BAC measures 27.42° and the measure of DE is 73.18°. Determine the measure of BC .
Answer:
BC = 18.34°
Step-by-step explanation:
The secant- secant angle BAC is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( DE - BC) = 27.42
[tex]\frac{1}{2}[/tex] ( 73.18 - BC ) = 27.42 ( multiply both sides by 2 )
73.18 - BC = 54.84 ( subtract 73.18 from both sides )
- BC = - 18.34° ( multiply both sides by - 1 )
BC = 18.34°

Answer:
E. 1d+0.015d
G. 1.015d
Step-by-step explanation:
A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.
Margaret has some cows. The cows produce an average total of 11.9
litres of milk per day for 290 days. Margaret sells the milk in 0.5 litre
bottles. Work out an estimate for the total number of bottles that
Margaret will be able to fill with the milk.
Answer:
6902
Step-by-step explanation:
Total milk produced in 290 days = 11.9 x 290 = 3451 litres
If 1 bottle has a capacity of 0.5l, the number of bottles needed = 3451 / 0.5 = 6902 bottles
In 2004 kyle was 8 years old . In 2006 kyle was was four year older than his cousin albert. a.how old was albert in 2004. b. in what year was albert born
Answer:
Albert was born in the year 2000!
Step-by-step explanation:
2006 Kyle is 10
10 - 4 = 6
So, Albert was 6 years old in 2006
6 - 6 = 0
2006 - 6 = 2000
Kyle was born in the year 2000.
Answer:
A) 4 years old
B) 2000
Step-by-step explanation:
A) 2004 Kyle was 8 years old. Two years pass which makes Kyle 10. Kyle is 4 years older than his cousin 10-4 equal 6. Albert was 6 in 2006. 6-2 equal 4
B) Albert is 6 (2006) which means he was born in 2000.

Answer:
m = 24
Step-by-step explanation:
m + 7° + 2m + 11° = 90°
3m + 18° = 90°
3m = 90°- 18°
3m = 72
(divide both sides by 3)
therefore : m = 24
Find g(f(x))
f(x) = -2x^2
g(x) = 3x -1
SHOW YOUR WORK
Answer:
-6x^2-1
Step-by-step explanation:
Find value
f(x)=-2x^2. g(x)=3x-1. Find g(f(x))
Solution:
f(x)=-2x2
g(x)=3x-1
g(f(x))=?
f(x)=-2x2,g(x)=3x-1,gof(x)=?
gof(x)=g(f(x))
Solution:
f(x)=-2x2
g(x)=3x-1
g(f(x))=?
f(x)=-2x2,g(x)=3x-1,gof(x)=?
gof(x)=g(f(x))
=g(-2x2)
=3⋅(-2x2)-1
=-6x2-1
gof(x)=-6x^2-1
