Answer:
r = 29.82
Step-by-step explanation:
We have the equation r/7.1 = 4.2 and are asked to solve for r.
To solve, we need to isolate r, do as followed and multiply 7.1 from both sides:
r/7.1 = 4.2
r = 29.82
Answer:
X=50°
Step-by-step explanation:
Let, the fourth angle in the quadrilateral be ∠A
The sum of all the four angles of the quadrilateral is 360°
So 40° + 110°+80°+∠A=360°
230°+∠A=360°
∠A=360°-230°
∠A=130°
The fourth angle of the quadrilateral is 130°
The angle A and X are the angles on a straight line
The sum of the angles on a straight line is 180°
so, ∠A+∠X=180°
130°+∠X=180°
∠X=180°-130°
X=50°
Answer:
The answer is B.
Step-by-step explanation:
In order to solve this problem, you need to combine like terms, which in this case, are the x's. So, if you add the numbers with the x's together, you get 3x + 12y. The 12y remains untouched because there are no other terms with the same variable.
