The complete question is
"Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each.
Explain what your solution means using complete sentences. How many t-shirts can she buy? Focus your answer on the difference between an equation and an inequality."
The expression that represents the number of t-shirts that Lisa can purchase is 14x + 58 = 150. The number of shirts that can be bought is 6.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Lisa has $150 at most to spend on clothes. She wants to buy a pair of jeans for $58 and will spend the rest on t-shirts that cost $14 each.
Let the number of shirts be x. The expression will be:
= (14 × x) + 58 = 150
14x + 58 = 150
Solving the expression will be:
14x + 58 = 150
14x = 150 - 58
14x = 92
x = 92/14
x = 6.5
The number of shirts that can be bought is 6.

Answer:
Step-by-step explanation:
The given quadratic equation is expressed as
(x + 3)² = 69
(x + 3)(x + 3) = 69
x² + 3x + 3x = 69
x² + 6x - 69 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = 6
c = - 69
Therefore,
x = [- 6 ± √(6² - 4 × 1 × - 69)]/2 × 1
x = [- 6 ± √(36 + 276)]/2
x = [- 6 ± √312]/2
x = (- 6 + 17.7)/2 or x = (- 6 - 17.7)/2
x = 11.7/2 or x = -23.7/2
x = 5.85 or x= - 11.85

Answer:
7.1 feet^2
Step-by-step explanation:
The base is made of a circular shape, so to solve this question we need to know how to calculate the circle area. The formula for the circle area is π * r^2 so we need to find the radius(r). Radius equal to half of the diameter and the diameter needed is 3 feet, then the area of the circle will be:
area = π * r^2
area = 3.14 * (3/2 feet)^2
area = 7.065 feet^2 = 7.1 feet^2
Answer: 220 in^3
Step-by-step explanation:
Area of the rectangle: 20x8 = 160
Area of right triangle: 8x15/2 = 60
Side of right triangle = 8, as the pythagorean triple 8,15,17 states C:
Area of the figure: rectangle + triangle = 160+60 = 220
Hope this helps!
