Answer:
Adding by 4 each time
Step-by-step explanation:
Answer:
we conclude that Kiera got the right 63 questions.
Step-by-step explanation:
Total questions = 90
The percentage of correct question = 70%
Using the formula
The number of correct questions = 70% of 90
= [70/100] × 90
= 0.7 × 90
= 63
Therefore, we conclude that Kiera got the right 63 questions.
Answer:
<1 = 33 degrees
<2 = 33 degrees
<3 = 114 degrees
Step-by-step explanation:
<1 and <2 = x
<3 = 3x+15
<1 + <2 + <3 = 180 degree
x + x + 3x + 15 = 180
5x = 180 - 15
x = 165/5
x = 33
<3 = 3(33)+15
= 114 degrees
The answer is n=28;
1. Subtract 14 from both sides (-n/2 = -14)
2. Multiply by 2 on both sides to get rid of the fraction (-n = -28)
3. Divide by -1 to get n by itself (n = 28)
You could also eliminate step three by multiplying by -2 instead of just 2.
Hope this helps!
