Answer:
6
Step-by-step explanation:
The trick here is to know PEMDAS.
PEMDAS stands for: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
This is the order in which you should simplify a problem.
Parentheses:
(5 + 1)^2 - (11 + 32) + 4
(6)^2 - (43) + 4
Exponents:
(6)^2 - (43) + 4
36 - 34 + 4
We have no multiplication or division, so we can skip those steps.
Addition:
36 - 34 + 4
40 - 34
Subtraction:
40 - 34
6
So 6 is our answer.

Width = w
d)length in term of width
w + 5
b)
2(w + w + 5) > 30
2(2w +5)>30
c)
solve
2(2w +5) > 30
4w + 10 > 30
4w > 20
w > 5
Answer:
Unit rate = 1 1/2 cups per serving
Step-by-step explanation:
1/2 serving has 3/4 cup
1 serving
3/4 * 1/2 = 3/4 * 2/1 = 6/4 = 6/4 / 2 = 3/2 = 1 1/2
Answer:
Question 6: x = 5/2
Question 7: b= 6
Step-by-step explanation:
Question 6:
Given that:
-2/5x + 3 = 2/3x + 1/3
Taking variables (terms with x) on left and constants on right side
Signs of transferred terms will be changed
-2/5x -2/3x = 1/3 - 3
Taking LCM on both sides
3/3*-2/5x - 2/3x*5/5 = 1/3 - 3*3/3
-6x/15 -10x/15 = (1-9)/3
-16x/15 = -8/3
Multiplying both sides by -15/16
-16x/15 * -15/16 = -8/3 * -15/16
- "-" sign when multiplied by "-" will give positive
- 3 will be cancelled by 15 giving 5
- 8 will be cancelled by 16 giving 2
x = 5/2
Question 7:
-2.6b + 4 = 0.9b - 17
Taking variables (terms with x) on left and constants on right side
Signs of transferred terms will be changed
-2.6b -0.9b = -17 -4
-3.5b = -21
Dividing both sides by -3.5
b = -21/-3.5
"-" sign will be cancelled out
b = 6
i hope it will help you!
