Step-by-step explanation:
Each of these equations holds true for one value of x from the set {5, 12, 15, 18}. Arrange the equations in increasing order of the x-values that make them true.
x + (x − 10) = 26
6x − 15 = 75
2(2x − 1) = 46
5x − 3x = 10
Answer:
5x - 3x = 10
2(2x - 1) = 46
6x - 15 = 75
x+(x - 10) = 26
Step-by-step explanation:
5x - 3x = 10
2x = 10 Divide by 2
x=5
2(2x - 1) = 46 Distribute the 2
4x - 2 = 46 Add 2
4x = 48 Subtract by 4
x = 12
6x - 15 = 75 Add 15
6x = 90 Divide by 6
x=15
x + x - 10 =26 Add the x's together and the 10
2x = 36 Divide by 2
x = 18

Ms.Alvarez's math class surveyed 10 students in 6th grade and 10 students in 7th grade. The class asked how many hours of chores each student did the previous weekend. The results were displayed in two histograms.
Mean is greater for grade 7.
Median is greater for grade 7.
So, the correct options are B and D.
What is mean and median?"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.
The median is the middle number in a set of values when those values are arranged from smallest to largest."
Mean for grade 6 is
= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]
= [tex]\frac{10}{7}[/tex]
Mean for grade 7 is
= [tex]\frac{1+2+5+2}{4}[/tex]
= [tex]\frac{10}{4}[/tex]
From both we get, Mean is greater for grade 7
Median for grade 6 is 1
Median for grade 7 is
= [tex]\frac{2+5}{2}[/tex]
= 3.5
From both we get, Median is greater for grade 7
So, the correct options are B and D.

Jack is making lemonade and mixes 3 liters of sugar with 8 liters of lemon juice. Which ratio of liters of sugar to lemon juice will make the concentration of lemonade?
A: 15 to 32
B: 9 to 6
C: 12 to 32
D: 6 to 24
Answer:
C. 12 to 32
Step-by-step explanation:
The simplified ratio would be 3:8
So multiply 3*4=12
And multiply 8*4=32
12:32
The reason the other ones wouldn't work is because 3 and 8 are not multiplied by the same number
For example
A.)15 to 32 wouldn't work because there not multiplied by the same number
3*5=15
8*4=32

Brian and Steve want to compare the prices of their favorite cereals to determine which is less expensive. Figure out the price for both cereals, and which is the less expensive.
Brian's cereal is $3.84 for 24 ounces.
Steve's cereal is $4.48 for 32 ounces
PLSSS HELPP
Answer:
Steve
Step-by-step explanation:
32 ounces for $4.48 each = $143.36 for 32 ounces
24 ounces for $3.84 each = $92.16 for 24 ounces
Steve's cereal is more expensive.
If you wanted to know how much each ounce cost and determine your answer:
Steve's cereal is still more expensive.

Triangle ABC is transformed to triangle A′B′C′, as shown below: A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0. Which equation shows the correct relationship between the measures of the angles of the two triangles? The measure of angle CAB = The measure of angle C prime B prime A prime The measure of angle BCA = The measure of angle A prime B prime C The measure of angle CAB = The measure of angle C prime A prime B prime The measure of angle BCA = The measure of angle C prime A prime B prime
Answer:
The measure of angle BCA = The measure of angle C prime A prime B prime
Step-by-step explanation:
The correct relationship between the measures of the angles of the two triangles is;
The measure of angle BCA = The measure of angle C prime A prime B.
Given thatTriangle ABC is transformed to triangle A′B′C′, as shown below:
A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes.
A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.
A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
We have to determineWhich equation shows the correct relationship between the measures of the angles of the two triangles?
According to the questionTriangle ABC is transformed to triangle A′B′C′, as shown below:
Here the triangle ABC is similar A'B'C' are similar triangles.
For similar triangles angles are congruent.
A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.
A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
Therefore,
<BAC = <B'A'C'
<ABC = <A'B'C'
<ACB = <A'C'B'
Hence, The correct relationship between the measures of the angles of the two triangles is The measure of angle BCA = The measure of angle C prime A prime B.

please help me,, you have to include an explanation !!
Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2

Mimi bought some fabric for a sewing project. The fabric cost $15.40 per meter. She bought 250 centimeters of fabric.
How much did Mimi pay for the fabric?
Answer:
$38.50
Step-by-step explanation:
so there are a hundred centimetres in a meter so u have to divide the 250 by 100
250 / 100 = 2.5 meters
and its 15.40 for 1 meter and she bought 2.5 so multiply those
15.40 * 2.5 = 38.50
she paid $38.50 for 2.5 meters of fabric
Answer:
$38.50
Step-by-step explanation:
There are 100 centimetres in a meter. If Mimi bought 250 centimetres of fabric, that is 2.5 meter. So then we do 2.5 x 15.40 = 38.50. Make sure you add the $ sign!
