Answer:
-58, -57, -56
Step-by-step explanation:
if the first integer is x,
the second integer must be x + 1 (because it's consecutive)
and the third must be x + 2
Therefore:
3 times the sum of the first and third integers is -342:
3 * (x + (x+2) ) = -342
Combine like terms in parentheses
3 * (2x + 2) = -342
Distribute the 3 to the 2x and the 2:
6x + 6 = -342
Subtract 6 on both sides
6x = -348
Divide by 6 on both sides
x = -58
x + 1 = -57
x + 2 = -56
-58, -57, -56
Check:
3 * (-58 + -56) = 3 * -114 = -342
Answer:
There are 9 boys and 12 girls in mrs Clark's class
Step-by-step explanation:
We are given that mrs Clark has 21 students, of which 3/7 are boys
In order to find the number of boys, we multiply 21 by 3/7 which results in 9
This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12
therefore there are 9 boys and 12 girls in mrs Clark's class
