How to solve them? Just move over the variables to one side and solve for them until you have just the variable, whilst doing the same actions to the side with only numbers. For parentheses with a coefficient, use distributive method.
Answer: x = 9
Step-by-step explanation:
15 / 20 = (2x + 3) / 28
cross multiply
15(28) = 20(2x + 3)
420 = 40x + 60
360 = 40x
x = 9
The average change in the value of the car each year:
4822 ÷ 5 = $964.40
Answer:
4.50
Step-by-step explanation:
sin 40°= opposite/hypotenuse
sin 40°= opp/7
0.6428= opp/7
multiply both sides by 7
4.4996= opp
to nearest hundredth = 4.50
