Answer:
20 mph
Step-by-step explanation:
First problem:
The new speed is 26 mph.
The old speed was x.
The new speed is 30% higher than the old speed.
1.3x = 26
x = 20
Answer: 20 mph
Second problem:
A number, perhaps a percent or a fraction, is missing from the problem.
Just count the amount of each letter and write it as a exponent = 3x²y³
Answer:
m∠k = 60°
Step-by-step explanation:
- an exterior angle of a triangle is equal to the sum of the opposite interior angles
4x + 2 + 6x - 12 = 130
to find x:
4x + 2 + 6x - 12 = 130
4x + 6x = 130 - 2 + 12
10x = 120
x = 120/10
x = 12
apply the value of x to find the measure of angle K:
k = 6*12 - 12 = 60
Write and solve a compound inequality to model the possible length of the dog run.
The inequality to model the possible length of the dog run is;. 100 ≤ 2.50x ≥ 200
And the possible length of the dog run is 80ft.
Minimum spending = $100
Maximum spending = $200
Cost per square feet = $2.50
let
x = possible number of square feet
The inequality:
100 ≤ 2.50x ≥ 200
This means possible number of square feet constructed is greater than or equal to $100 or less than or equal to $200
solve:
100 ≤ 2.50x ≥ 200
divide the inequality into 2
100 ≤ 2.50x
x ≤ 100/2.5
x ≤ 40
the other part:
2.50x ≥ 200
x ≥ 200/2.50
x ≥ 80
Therefore,
the possible length of the dog run is 80 feet
