Answer:
x=-16
Step-by-step explanation:
6x+12=4x-20
2x=-32
x=-16
Let:
P - perimeter
l - length
w - width
We know:
P = 118 m
l = 2w - 7
<h3>Rectangle perimeter's formula: P = 2l + 2w</h3>
We replace the length with 2w - 7.
P = 2×(2w - 7) + 2w
118 = 4w - 14 + 2w
118 = 6w - 14
6w = 118 + 14
6w = 132
w = 22 meters
Answer:
Step-by-step explanation:
the anser is 315,000
Given:
6 girls
4 boys
Probability of 1 girl being chosen: 1/6
Probability of 1 boy being chosen: 1/4
Probability of another boy being chosen: 1/3
1/6 = 0.17 x 100% = 17%
1/4 = 0.25 x 100% = 25%
1/3 = 0.33 x 100% = 33%
17% + 25% + 33% = 75%
The probability that exactly one girl and two boys will receive awards is 75%.
