- Division
- Addition
- Subtraction
Step-by-step explanation:
<u>Step 1: Define</u>
3x² - 4(2y - 4/12) + 8
x = 6, y = 2
<u>Step 2: Evaluate</u>
- Substitute in variables: 3(6)² - 4(2(2) - 4/12) + 8
- Evaluate exponents: 3(36) - 4(2(2) - 4/12) + 8
- Multiply: 108 - 4(2(2) - 4/12) + 8
- (Parenthesis) Multiply: 108 - 4(4 - 4/12) + 8
- (Parenthesis - Fraction) Simplify: 108 - 4(4 - 1/3) + 8
- (Parenthesis) Subtract: 108 - 4(11/3) + 8
- Multiply: 108 - 44/3 + 8
- Subtract: 280/3 + 8
- Add: 304/3
Answer: 169'
Step-by-step explanation:
Since the expression for ordering brushes for an art class is given as 5c - 1, where c is the class limit.
Therefore, when the class limit is 34, the expression evaluated will then be:
= 5c - 1
= 5(34) - 1
= 170 - 1
= 169
Therefore, 169 brushes were ordered.
Answer:

Answer : Square root of 21 , -4 2/3, -30/7 , -31/6 .
Explanation :
-4 2/3 = -10/3 = -3.3333
Square root of 21 = 4.58258
-31/6 = -5.1666
-30/7 = 4.2857
And arrange them from greatest to least and there we have the answer.
Hope this helps you understand !!!!
