Answer:
The simplification for the expression is given as =( 7 + 2(a-3))/(a-3)
Step-by-step explanation:
To simplify the expression we will first convert the words to values in numbers and alphabets.
StartFraction 5 Over a minus 3 EndFraction minus 4 divided by 2 + StartFraction 1 Over a minus 3 EndFraction
= 5/(a-3) -4/2 + 2/(a-3)
Having done that, let's move on and simplify the expression.
5/(a-3) -4/2 + 2/(a-3)
= 5/(a-3) -2+ 2/(a-3)
= 5/(a-3) + 2/(a-3) -2
= 7/(a-3) -2
=( 7 + 2(a-3))/(a-3)

Answer:
the number of boys in the competition is 45 boys
Step-by-step explanation:
The computation of the number of boys in the competition is as follows:
Given that
Ratio of boys to girls is 15:16
And, the total participants is 93
So, the number of boys is
= Total participants × boys ratio ÷ total ratio
= 93 × 15 ÷ (15 + 16)
= 93 × 15 ÷ 31
= 45 boys
hence, the number of boys in the competition is 45 boys
Answer:
$630
Step-by-step explanation:
1000 x .09 = 90
90 x 7 = 630
First I would convert 20 and 12 to millimeters which would be 20= 200mm 12= 120mm. You would then find the area if the grid which would be 200•120=
