-x + 7 = x - 5
add x to both sides of the equation
7 = 2x - 5
add 5 to both sides of the equation
12 = 2x
divide 2 from both sides of the equation
6 = x
He can give at most 2 adult haircuts with the remaining time
<h3>How many adult haircuts at most can he give with the remaining time? </h3>
The inequality is given as:
0.75C + 1.25A <= 7
Also, we have
C = 5
Substitute C = 5 in 0.75C + 1.25A <= 7
0.75 * 5 + 1.25A <= 7
Evaluate the product
3.75 + 1.25A <= 7
Evaluate the like terms
1.25A <= 3.25
Divide by 1.25
A <= 2.6
Rewrite as
A < 3
Hence, he can give at most 2 adult haircuts with the remaining time

AB = 7 1/2
BC = 2 1/4
DE = 1 1/4
AB = GH + EF + CD
AH + FG = DE + BC
The perimeter is AB + BC + CD + DE + EF + FG + GH + HA.
AB + BC + CD + DE + EF + FG + GH + HA =
= AB + BC + DE + AB + DE + BC =
= 2AB +2BC +2DE =
= 2 · 7 1/2 + 2 · 2 1/4 + 2 · 1 1/4 =
= 15 + 4 2/4 + 2 2/4 =
= 15 + 4 1/2 + 2 1/2 =
= 19 1/2 + 2 1/2 =
= 22 [m]
Answer:
What is the probability formula?
Image result
In general, the probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
