Answer:
2
Step-by-step explanation:
2y=4x-5
divide each side by 2
y=2x-5/2
Answer:
3
Step-by-step explanation:
(20a - 1) ÷ b
a = 2
b = 13
(20(2) - 1) ÷ 13
(40-1)÷13
39÷ 13
= 3
The function formula will be
G= 50 + 125x
Since we have given that
Charges per each magical broom he makes for his customers = 125 gold pieces
Charges of one-time fees = 50 gold pieces
Let the number of magical brooms he makes be 'x'.
Let the total number of gold pieces be 'G'.
According to the question, it becomes
G= 50 + 125x
Hence, the function formula will be
G= 50 + 125x
A formula is a fact or rule written in mathematical symbols. An equal sign usually connects two or more quantities. If you know the value of one quantity, you can use a formula to find the value of the other.
