Answer:
The answer is 2
Step-by-step explanation:
The total amount Ali biked was over two years. To find that amount, you add the amount he biked each year. Since he biked 261 miles in one year and c miles in the other, the total amount of miles is 261 + c. That would be the expression used to describe the total number of miles.
Answer:
40
Step-by-step explanation:
The scale factor of 5 to the side measuring 8 means that you multiply that side by the scale factor.
Basically, the equation would go like this:
Original Side Length: x
Scale Factor: y
New Side Length: z
xy=z
If we plug in our numbers, we get:
8*5=z
40=z
<u>40</u>
Answer:
x = 20
y = 70
Step-by-step explanation:
Solve for x:
5x - 20 = 3x + 20
2x - 20 = 20
2x = 40
x = 20°
Solve for y:
x + y = 90°;
(20) + y = 90°
y = 90 - 20
y = 70°
Hope this helps!
