Step-by-step explanation:
5B+4F= $30.76
×3
15B+12F= $92.28
----------------------------
8B+6F= $48.28
×2
16B+12F= $96.56
----------------------------
Cost of one burger:
$97.56-$92.28= $4.28 (final ans)
Cost of one fries:
$30.76-5($4.28)= $9.36 (for 5 fries)
$9.36÷5= $1.87 (final ans)
Answer:
y = 0.5x + 2
Step-by-step explanation:
the y-intercept is 2, as shown in the graph
the slope is 0.5. this is because while the x-value goes up by 2, the y-value goes up by one (from 0, 2 to 2, 3).
using the slope formula of rise / run, you get 1/2, which is equal to 0.5
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
4(x−7)=2(x+3)
Simplify both sides of the equation.
4(x−7)=2(x+3)
4x+−28=2x+6
4x−28=2x+6
Subtract 2x from both sides.
4x−28−2x=2x+6−2x
x−28=6
Add 28 to both sides.
2x−28+28=6+28
2x=34
Divide both sides by 2.
2x/2 = 34/2
x = 17
Simplification = 3.5x + 2.5x
Result = 6x
Answer:
Step-by-step explanation:
Geometric formula sequence: 
(where 
is the first term of the sequence and 
is the common ratio)
To find the common ratio, divide one of the terms by the previous term:
From inspection, 
Therefore,
