Answer:
Step-by-step explanation:
Perimeter = 84 cm
2*(length + width) = 84
2* (2x - 8 + x - 2) = 84
2*(2x + x - 8 - 2) = 84 {bring like terms together}
2*(3x - 10) = 84 {add/ subtract like terms}
Divide both sides by 2

3x - 10 = 42
3x - 10 +10 = 42 + 10 {add 10 to both sides}
3x = 52
Divide by 3,

x= 17 1/3
Length = 2x - 8

Answer:
<h3>83°</h3>
Step-by-step explanation:
Given the parameters
m2 ROC = 31° and
m2 COL = 52°
According to the diagram in the attachment;
m2 ROL = m2 ROC + m2 COL
Substitute the given values into the expression as shown;
m2 ROL= 31°+52°
m2 ROL = 83°
Answer:
-6
Step-by-step explanation:
You multiply -2 by 3 and you get -6.
2 negatives or 2 positives equals a positive number in Multiplication and Division.
But a Negative number and a positive number equals a negative number in Multiplication and Division.
Answer:
The answer is B
Step-by-step explanation:
75 + x = 90
First, Virginia had to write an equation to solve for x.
75 - 75 + x = 90 - 75
Second, Virginia used the subtraction property of equality to isolate x.
x = 15
Third, "x = 15" was the answer Virginia got after subtracting 90 and 75.
75 + 15 = 90
Finally, she had to verify her answer
Answer:
Answer:
The student council made more snow cones per hour than the parent volunteers.
Explanation:
To find the number of snow cones made per hour:
XXX
Divide the number of snow cones made
XXX
by the number of hours spent making snow cones.
Parent volunteers
XXX
Number of snow cones:
120
XXX
Number of hours spent making snow cones:
5
Number of snow cones per hour:
120
÷
5
=
24
Student council
XXX
Number of snow cones:
100
XXX
Number of hours spent making snow cones:
4
Number of snow cones per hour:
100
÷
4
=
25
Since the student council made
25
snow cones per hour and the parent volunteers only made
24
snow cones per hour:
the student council made more snow cones per hour.
