Answer:
B. 40
Step-by-step explanation:
We know that the large angle is 90 degrees as it is a right angle. Thus,
(I don't know how to include degree symbols). We solve:
, so then
. Thus, x is forty degrees and the answer is B.
Answer:
No solution
Step-by-step explanation:
2(9x-5)=6(3x+4)
Step 1 is to do distributive property.
so you will get this:
18x-10=18+24
step 2 is combining like terms.
so you will subtract 24x from both sides.
(this:) 18x-10=18x+24
(into this:) -10=24
I got this because when you subtract 18 from 18 you will get zero (0).
So your answer will be:
No solution
70%=70/100=7/10
what you do is shade 7 of the squares and say that is 21
now each square is worth the same
so 21/7=3
each square is worth 3
10 squares
3 times 10 is 30
the number is 30
see diagram
Answer:
17°
Step-by-step explanation:
∠AOC is a right angle, so it measures 90°
∠AOB and ∠BOC are in ∠AOC, so m∠AOB + m∠BOC = 90
m∠AOB = 73°
m∠BOC = x (shown in the diagram)
73 + x = 90
x = 17
<span>An equation with more than one operations can be also called several-step equation, because requires multiple operations to be solved.There is a order which operation you should do first. The equation can be solved in several steps an that's why is it not a one-step equation.</span>
