In an equation the Left hand side must equal the right hand side
4(5y-8-2)=185-15
20y-32-8=170
20y=170+32+8
20y=210
Therefore y=10,5
When you substitute the 10,5 and solve it on the left and side it's equal to 170 which is the answer on the right hand side
Answer:
Okay so this is simple addition, once you know how to do it.
The interior angles of a triangle should always add up to 180 Degrees.
Now that you know this, all you have to do is add the numbers together and see which ones add up to 180 degrees.
A. - 90+42+58=190
B. - 60+60+60=180
C. - 100+48+42=190
D. - 31+75+70=176
Out of these choices the only one that adds up to 180 is B. So your answer would be B.

Answer:
The width of the yard is 20 ft
Step-by-step explanation:
In this particular question, we are asked to calculate the width of the rectangular front yard given the area of the front yard and the length of the front yard.
Mathematically, the area of the front yard is calculated by multiplying the length of the front yard by the breadth of the front yard.
Let’s say A = L * W
Substituting the known values, the unknown width would thus be:
W = A/L = 600 sq.ft / 30ft
W = 20 ft
