Subtract 9 from both sides
b = -12 - 9
simplify -12 - 9
Answer: b = -21
9 + -21 = -12 is true.
simplify brackets
simplify q + -9 to q - 9
add 9 to both sides
simplify 12 + 9 to 21
q = 21
21 + -9 = 12 is true.
Answer:
54m2
Step-by-step explanation:
Cut the shape into two - from the 9m length. One has 3m by 8m(ie 5m + 3m) dimensions, and the other 6m(ie 9m - 3m) by 5m dimensions.
Taking area of first one=24m2,then area of the second =30m2.
To get area of whole shape, we add both areas=54m2
NB:Area=l×b
Answer:
5:6
Step-by-step explanation:
the ratio before would be 10/12 so you would have to divide both sides by 2 so you would get 5/6.Hope this helped
Answer:
A
Step-by-step explanation:
Big Brain
Step-by-step explanation:
a < (a + b)/2 < b
Solve the first inequality.
a < (a + b)/2
2a < a + b
a < b
Solve the second inequality.
(a + b)/2 < b
a + b < 2b
a < b
Both inequalities are true. Therefore, a < (a + b)/2 < b.
