Answer:
-16
Step-by-step explanation:
Represent the number by n.
Then:
8(n + 18) = 16
Performing the indicated multiplication, we get:
8n + 144 = 16
Subtracting 144 from both sides results in 8n = -128.
Dividing both sides by 8: n = -128/8 = -16
The number was -16.
Answer:
a) 15 ÷ 2/3=
=1 5 x 3/2=45/2
b) 3 × 1/8 × 6/9
=1/8 x 2( Simplify 3 with 9 remainder 3, reduce
6 with 3 remainder 2)
=1/4
c) 3 3/5 ÷ 2 2/5
=18/5 : 12/5
=18/5 . 5/12
=3/2
d) 2 1/12 × 1 1/5
= 25/12 . 6/5
=5/2
Step-by-step explanation:
In this problem, we have to find the factor which will
make (1 / 10) equal to (2 / 5). Therefore we can write it as:
x (1 / 10) = 2 / 5
where x is the number of people who ate the blueberries
x = (2 / 5) / (1 / 10)
x = 4
<span>Therefore 4 people ate the blueberries.</span>
40 and 60
40 = 20 x 2
60 = 20 x 3
GCF = 20
<span>the greatest number of teams coach can make is 20
each team can have 2 girls and 3 boys</span>
If you are looking for the surface area of the cube, it is 169. The equation for the surface area of a square is base times height. This would mean it’s 13x13 since all the sides are the same. 13x13=169
