Answer:
20
Step-by-step explanation:
The two given and marked angles add up to 90.
A = x
B = 3x + 10
A + B = 90 Substitute for A and B. A and B are just letters I gave things.
x + 3x + 10 = 90 Combine the left
4x + 10 = 90 Subtract 10 from both sides.
4x +10-10 = 90-10 Combine
4x = 80 Divide by 4
4x/4=80/4
x = 20
Answer: A. 47
Step-by-step explanation: The answer would be 47 degrees because the 47 degree angle has one mark, and so does x and y. This means that these angles are the same.
Answer:
x=24
Step-by-step explanation:
-5x+12x-8x=-24
Add like terms
12x-13x=-24
-x=-24
divide by 1
x=24
Answer:
Refer to the attachment for explication of steps. :)
the answer is 2/3 and the y intercept is 2. we can find the y intercept because its where the line crosses the y axis and the slope by calculating rise and run using 2 points bebe :)
