Answer:
112
Step-by-step explanation:
A supplementary angle is 1 or more angles that add up to 180 degrees. So, the 2 angles we have are 2x and 3x + 10, and those add up to 180.
In order to make an equation for this, we need to add 2x and 3x + 10 and equal it to 180.
5x + 10 = 180
Now that we have our equation, the goal is to isolate the variable. The most immediate step I see is to subtract 10 from both sides so 5x will be alone on one side of the equation.
5x = 170
Now, to ultimately isolate the variable, we must divide both sides by 5 so that x will be alone.
170 / 5 is 34
5x / 5 is x
x = 34
Now, we plug in our value of x into 3x + 10 to find out what the measurement is equal to.
3(34) + 10 = y
102 + 10 = y
112 = y
3x + 10 is equal to 112.
2 1/6 is about 2 and 4 1/2 is about 5 so we multiply the two to get 10
The actual answer would be 13/6 * 9/2 = 117/12 = 9 and 9/12 or 9 and 3/4, so we know the estimate was good
3,4,5 units
3+4+5=12
the perimiter can be split into 12 units
48=12 units
divide by 12
4=1 units
3<4<5
longest side is 5 units
4=1unit
times both sides by 5
20=5 units
answer is D. 20
Given:
The given term is 3x.
To find:
The like terms.
Solution:
Like terms are the terms which contain same variable and degree.
In the given term 3x, the variable is x and its degree is 1.
The variable in 4y is y and, 8 and 0.257 are constant. So, 4y, 8, 0.257 and 3x are not like terms.
On 10 has variable x and degree 1. So, 3x and 10x are like terms.
Therefore, the correct option is B.
