Answer:
the answer is 75.
Step-by-step explanation:
hope this helps.
4 x 7 is 28, and 8 x 7 is 56. You can use 4 x 7 to find 8 x 7 by multiplying that first and doubling that quotient.
Half of 56 is 28, therefore doubling that allows us to find the quotient of 8 x 7.
3n=15-(6/3)
3n=15-2
3n=13
n=(13/3)
Answer:
x=-3
Step-by-step explanation:
3(2+x)= -3
Divide each side by 3
3/3 (2+x)= -3/3
2+x = -1
Subtract 2 from each side
2+x-2 = -1-2
x = -3
