Answer:
70
Step-by-step explanation:
180 -(60+65) = 180 - 125 = 55
180 - (50 + 55) = 180 - 105 = 75
180 - (35 + 75) = 180 - 110 = 70
Answer:
Four is the final answer (4)
Step-by-step explanation: Have a brilliant day of learning!
In order from top to bottom, 2,8,14,20
And it’s the second graph (right)
20 = 2 x 2 x 5
15 = 3 x 5
common divisor (CD) of 20 and 15 is 5 so n should be 5 and each group has 4 boys and 3 girls.
If there are more than one CD, then there are more than one answer.
If they ask for the largest number of groups, greatest common divisor (GCD) will be the answer.
