AleksandrR [38]

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

4T + 7F = 38.3

5T + 5F = 40.75

Required

Determine the values of T and F

5T + 5F = 40.75

Divide through by 5

T + F = 8.15

Make F the subject

F = 8.15 - T

Substitute 8.15 - T for F in the first equation

4T + 7F = 38.3

4T + 7(8.15 - T) = 38.30

4T + 57.05 - 7T = 38.30

Collect Like Terms

4T  - 7T = 38.30 - 57.05

-3T = -18.75

Solve for T

T = -18.75/-3

T = 6.25

Recall that:

F = 8.15 - T

F = 8.15 - 6.25

F = 1.90

VXYZ is a rectangle with a length of 20cm and a width of 12 cm. The length of the rectangle is increased by 30%. The width of th
katrin [286]

Step-by-step explanation:

the area is

length × width

increasing the length by 30% means multiplying the original length by 1.3.

increasing the width by 10% means multiplying the original width by 1.1.

so, the new area is (by using the old length and width)

length × 1.3 × width × 1.1 = length × width × 1.3×1.1 =

= old area × 1.3 × 1.1 = old area × 1.43

so, the area increases by 43%.
