If the change in the number of pounds is p, the change in the cost will be $11c.
This is because each pound costs $11.
Answer:
-63
Step-by-step explanation:
5×9 = 45
45/-5 = -9
-9×7 = -63
The answer is C. The solution to a linear equation always is the variable equaling another number. 4=5 is a false statement along with not being a linear solution.
Semicircle area
a = 1/2 × area of circle
a = 1/2 × π × r²
Triangle area
a = 1/2 × b × h
With the formula above, input the numbers which are given in the question
Semicircle area
a = 1/2 × π × r²
a = 1/2 × 3.14 × 5²
a = 1/2 × 3.14 × 25
a = 39.25 cm²
Triangle area
a = 1/2 × b × h
a = 1/2 × 5 × 4.5
a = 1/2 × 22.5
a = 11.25 cm²
Combining the area
a = semicircle area + triangle area
a = 39.25 + 11.25
a = 50.5 cm²
the closest area is fourth option
