mall fries for a total of $29.56. How much does each item cost individually ?
1 answer:
Answer:
Step-by-step explanation:
Let burger = b and fries = f
<u>Alica:</u>
<u>Jack:</u>
<u>Simplify the second equation and subtract from the first one:</u>
- 2b + f = 14.78
- 2b + 3f - 2b - f = 21.18 - 14.78
- 2f = 6.4
- f = 3.2
<u>Find the value of b:</u>
- 2b + 3.2 = 14.78
- 2b = 11.58
- b = 11.58/2
- b = 5.79

Answer:
f = -8
Step-by-step explanation:
7(f+3)+9=5(f-2)-3f
7f + 21 + 9 = 5f - 10 - 3f
7f + 30 = 2f - 10
5f = -40
f = -8
Answer:
2677
Step-by-step explanation:
Let's make this easier first of all:
a^2-y^3(a-y^2)y^2
a^2-y^5(a-y^2)
a^2-ay^5+y^7
(-2)^2-(-2)(3)^5+3^7
4-(-2*243)+2187
4-(-486)+2187
4+486+2187
490+2187
2677
3/4+m=5/4
Subtract 3/4 from both sides
