Solve the equation by inserting 7 for x.
Our equation is now y=2.5(7)-1.5
Multiply.
Y=17.5-1.5
Subtract
Y=16
The answer is D. 16
Hope this helps!
Answer:
x= -2
Step-by-step explanation:
9(x-1)=7x-13 1) do distributive property
9x-9=7x-13 2) add nine to both sides which means you would take out the 9 since -9 and 9 cancel out each other and add 9 to -13
9x=7x-4 3) subtract 7x from both sides which means you would remove the 7x since -7x and 7x cancel out each other and subtract 7x from 9x
2x=-4 4) divide both sides by 2
x= -2
Sorry if this was confusing
The first part cannot be answered here without the diagram. However, I can tell you that the model he's building is 1/10 the size of the actual car. That means every measurement on the car is divided by 10 to get the model measurement.
The radius of the car wheel is 27 inches, so the diameter is 54 inches. Using what we know about the model, the correct proportions for the model wheel diameters would be 54 / 10, or 5.4, inches. Therefore, wheels with a diameter of 6 inches would not be in proportion with the model.
