Katarina [22]3 years ago

Let the "other" angle be x. Then we can set up the equation: 2x + 60 + x = 180, because supplementary means that the angles add up to 180 degrees.
We get:
3x + 60 = 180
3x = 120
x = 40.
2(40) + 60 = 80 + 60 = 140.
So one angle is 140 degrees and the other angle is 40 degrees.

Solve the equation. Check your answers.<br>29=7x+5-4x​
Vladimir [108]

Answer:

x = 8

Step-by-step explanation:

29=7x + 5 -4x

add like terms: 29 = 3x +5

get your x variable on one side

24 = 3x

divide by 3

x = 8

check!

29 = 7(8) + 5 -4(8)

29 = 56 + 5 -32

29 = 51 - 32

29 = 29

dolphi86 [110]
The question is, "how many ways ...". 

There are as many ways to solve a math problem as you can think of. (Some are shorter or easier than others.)

Essentially, an infinite number.
