What is the value of the expression below when x=8 and y=4
9x-2y
Answer 64
Step-by-step explanation: if x is 8 you do 8 x 9 which is 72. Then you do 2 x 4 which is 8. So now you have 72 - 8 which is 64.
MATH
1. Solve for x: 2x + 8 = 180
x=
2.Solve for x: 3x - 3 = 90
x=
3.Solve for x: 2x - 5 + x - 7 = 180
x=
4.Solve for x: x + 1 + x + 4 + x - 2 = 90
x=
Answer:
1. x = 86
2. x = 31
3. x = 64
4. x = 29
Step-by-step explanation:
1. 2x + 8 = 180
-8 -8
2x = 180 (divide both sides by 2 to get x by itself)
2. 3x - 3 = 90
+ 3 +3
3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)
3. 2x -5 + x - 7 = 180 (you combine like-terms)
3x -12 = 180
+12 +12
3x = 192 (you divide by 3 on both sides)
4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)
3x + 3 = 90
-3 -3
3x = 87 (divide both sides by 3)
Answer:
1) 2x + 8 = 180
Take 8 to the right side.
2x = 172
Divide both sides by 2.
x = 86
2) 3x - 3 = 90
Take -3 to the right side.
3x = 93
Divide both sides by 3.
x = 31
3) 2x - 5 + x - 7 = 180
Combine like terms.
3x - 12 = 180
Take -12 to right side.
3x = 192
Divide both sides by 3.
x = 64
4) x + 1 + x + 4 + x - 2 = 90
Combine like terms
3x + 3 = 90
Take 3 to right side.
3x = 87
Divide both sides by 3.
x = 29

Write the formula, substitution, and solve. A parallelogram is being painted on the wall of a playroom. The parallelogram measures 8 meters in length and 5 meters in height. What is the area of the parallelogram?
Answer:
Area: 40
Step-by-step explanation:
To find the area of a parallelogram you multiply the base times the height, or the length times the height. This is why you multiply 5x8 to get 40. The substitution could be 5 x 8 = X
X is the area.

Find the lower quartile and upper quartile of the data set. 10, 11, 13,18,19,21,22,25,27,30,32
The lower quartile value is 13 and the upper quartile value is 27.
What is a Quartile?
A quartile divides the data set into four equal halves, that is, each set has an equal number of terms. The quartiles are given by Q₁(the lower quartile value), Q₂ (the median), Q₃ (the upper quartile value).
We first arrange the data set in ascending order. Here, the data set is already in ascending order, that is, 10,11,13,18,19,21,22,25,27,30,32.
So we will divide the above set into two equal halves. As the given set has 11 terms,
So the median is [tex]\frac{n+1}{2}[/tex] where n is the number of terms.
We have n=11
⇒ Median= [tex]\frac{11+1}{2}[/tex] th term
= 6th term
⇒ Median= 21
Now the data to the left side of the median value will give the lower quartile and the data to the right will give the upper quartile.
The data to the left of median value 21 is 10,11,13,18,19.
The median value of this data will give the lower quartile value.
Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term
=13
⇒Lower quartile is 13.
The data to the right of the median value 21 is 22,25,27,30,32
The median value of this data will give the upper quartile value.
Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term
= 27
⇒Upper quartile is 27.
The correct answer is lower quartile= 13, upper quartile = 27

Find the rule that gives the number of dots needed to form the nth figure in each pattern.
Answer: adding a column and a row
Step-by-step explanation:
The rule which give the number of dots for the nth figure is [tex]= n^{2}[/tex] or number of dots [tex]= n \times n[/tex], where n represents the number of figure.
What is pattern?A pattern is a repeated arrangement of numbers, shapes, colors and so on.
Let n represents the number of figure and m be the number of dots.
According to the given question.
We have some figures which is made up of dots with following some patterns.
In the given first figure i.e. for n = 1
The total number of dots is 1.
[tex]\implies m = 1[/tex]
In the second figure i.e. for n = 2
The number of dots gets increased and the counts of dots are 4.
⇒ [tex]m = 4[/tex]
[tex]\implies m = 2 \times 2[/tex]
In the third figure i.e. for n = 3.
The number of dots are 9
[tex]\implies m = 9[/tex]
[tex]\implies m = 3 \times 3[/tex]
Similarly, for the nth figure, the number of dots is given by
[tex]m = n \times n[/tex]
[tex]\implies m = n^{2}[/tex]
Hence, the rule which give the number of dots for the nth figure is number of dots [tex]= n^{2}[/tex] or number of dots [tex]= n \times n[/tex], where n represents the number of figure.

This figure has an area of____in^2
--Answer--
[tex]5\sqrt{2}[/tex] or 7.0710... (7.1)
--Explanation--
If you look closely the triangle on the left could be moved to the space on the right of the shape.
Then, the edges would be 10 inches (top) and 5 inches (sides).
From there, you multiply 10 x 5 to get 50. If you want the square root, you do [tex]\sqrt{50}[/tex] which is how I got 7.071067812, or 7.1, which was rounded to the nearest tenth.
