What is the equation?
3.7 = 5x + 12.2

x= -1.7

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

x = -1.7.

Step-by-step explanation:

3.7 = 5x + 12.2

Subtract 3.7 from both sides:

0 = 5x + 12.2 - 3.7

0 = 5x + 8.5

Subtract 5x from both sides:

-5x = 8.5

x = 8.5 / -5

x = -1.7.

1 and 2

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
