Answer:
1. X is added to 8
2. Subtract 14 by a number
3. Multiply 2 after you add 3 into a number.
4.. Twice a number plus 3
5. Divide 15 by a number
Step-by-step explanation:
<span>Let x= measure of sides that have common length
then from "the third side measures 5m less than twice the common length."
2x-5= third side
.
Because they gave us the perimeter we have:
11 = x+x+2x-5</span><span>11 = 4x-5
16 = 4x
4 m = x
.
third side:
2x- 5 =2(4)-5 = 8-5= 3m</span>
Length answers:
4m, 4m, and 3m
Answer:
x ≥ 1/2
x ≤ -3
Step-by-step explanation:
2x² + 5x - 3 ≥ 0
Factor left side.
(2x - 1)(x + 3) ≥ 0
Set factors in an inequality to 0.
2x - 1 ≥ 0
2x ≥ 1
x ≥ 1/2
You multiply both sides by 2x - 1, so the sign switches.
x + 3 ≤ 0
x ≤ -3
Given that
Rate of building road = 3.75 km per week
Road built for weeks = 3 weeks
As road built in 1 week = 3.75 km
Then road built in 3 weeks = 3 × 3.75 km
Hence 11.25 km road is built .
