Answer:
2 second one cuz x can't be smaller than 0 because x is SQUARED
Assuming the five frame is for the number five (5) then place 5 counters in the frame.
For the first one a = 2.5. For the second one m = 4. For the third one m = -4
4(a-2)=3(a+4)
4a-8=3a+12
a=20
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.
