I think the cost is less than a dollar. 1 container of soup has 120/3 = 40 bowls
if 1 container costs $30; each bowl costs: 30/40 = $0.75
-x - 7y = 18
4x + 7y = -30
The -7y and 7y cancel by addition.
Thus, 3x = -12
Divide both sides by 3
x = -4
Plug in -4 for x
Thus, -(-4) - 7y = 18
4 - 7y = 18
Subtract 4 to both sides; 4 - 4 - 7y = 18 - 4
Simplify, -7y = 14
Divide both sides by -7; -7y/-7 = 14 / -7
y = -2
set it up like a y= equation.
which would be y=-x^2+7
to find the vertex, you substitute the 0s.
so 0=-(0)^2+7
-0^2=0
0+7=7
0=7
(0,7)
Answer: 35
Step-by-step explanation:
If there is 50 pieces of fruit in total then . . . find out how much the percentages are ( remember to do that SEPARATELY )
What is 20% of 50 ? 10 pieces
Equation : 20 ( percentage ) times 50 ( whole )
What is 10% of 50 ? 5 pieces
Equation : 10 ( percentage ) times 50 ( whole )
total of apples and grapes in the fruit bowl : 15
Finally do . . . 50 - 15 = 35 pieces
