Answer:
b = (-3)/2
Step-by-step explanation:
Solve for b:
(-10 b)/3 = 5
Multiply both sides of (-10 b)/3 = 5 by -3/10:
(-3 (-10) b)/(10×3) = (-3)/10×5
(-3)/10×(-10)/3 = (-3 (-10))/(10×3):
(-3 (-10))/(10×3) b = (-3)/10×5
(-3)/10×5 = (-3×5)/10:
(-3 (-10) b)/(10×3) = (-3×5)/10
(-10)/10 = (10 (-1))/10 = -1:
(-3-1 b)/3 = (-3×5)/10
(-3)/3 = (3 (-1))/3 = -1:
--1 b = (-3×5)/10
(-1)^2 = 1:
b = (-3×5)/10
5/10 = 5/(5×2) = 1/2:
Answer: b = (-3)/2
Answer:
1. 5
2. 1.29
3. 9.90
Step-by-step explanation:
They are buying 5 of each thing, so multiply it by 5.
The diced tomatoes cost $1.29.
When you solve the equation, you get 9.9. Convert that to money, and you have $9.90

Radius of a Circle Formula: r = d/2
Area of a Circle Formula: A = πr²
Step-by-step explanation:
<u>Step 1: Define</u>
Diameter <em>d</em> = 18 units
<u>Step 2: Manipulate Variables</u>
Radius <em>r</em> = 18 units/2 = 9 units
<u>Step 3: Find Area</u>
- Substitute in <em>r</em> [Area of a Circle Formula]: A = π(9 units)²
- [Area] Evaluate exponents: A = π(81 units²)
- [Area] Multiply: A = 81π units²
Answer:
Write the new equation in slope-intercept form. Replace the old slope with the new slope. Replace the y-intercept's value with a variable (b).
