m/5=3(2m+1) verbal expression
Answers
Answer:
m = -15/29
Step-by-step explanation:
1) Distribute
[tex]\frac{m}{5} =6m+3[/tex]
2) Subtract 6m from both sides of the equation
[tex]\frac{m}{5} -6m=6m+3-6m[/tex]
3) Simplify
a. Find common denominator
[tex]\frac{m}{5} +\frac{5(-6)m}{5} =6m+3-6m[/tex]
b. Combine fractions with common denominator
[tex]\frac{m+5(-6)m}{5} =6m+3-6m[/tex]
c. Multiply the numbers
[tex]\frac{m-30m}{5} =6m+3-6m[/tex]
d. Combine like terms
[tex]\frac{-29m}{5} =6m+3-6m[/tex]
e. Combine like terms
[tex]\frac{-29m}{5} =3[/tex]
4) Multiply all terms by the same value to eliminate fraction denominators
[tex]5 *\frac{-29m}{5} =5*3[/tex]
5) Cancel multiplied terms that are in the denominator
[tex]-29m=5*3[/tex]
6) Multiply the numbers
[tex]-29m=15[/tex]
7) Divide both sides of the equation by the same term
[tex]\frac{-29m}{29} =\frac{15}{-29}[/tex]
8) Simplify
a. Cancel terms that are in both the numerator and denominator
[tex]m=\frac{15}{-29}[/tex]
b. Divide the numbers
[tex]m=-\frac{15}{29}[/tex]
Which equation represents a line that has a slope of 1/3 and passes through point (-2,1)?
Answers
Answer:
The equation would be y - 1 = 1/3(x + 2)
Step-by-step explanation:
In order to find this, we simply plug the values we have into point slope form.
y - y1 = m(x - x1)
y - 1 = 1/3(x - -2)
y - 1 = 1/3(x + 2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Slope = m = 1/3
(-2 , 1)
[tex]y - y_{1}= m(x - x_{1})\\y - 1 = \dfrac{1}{3}(x -[-2] )\\\\y - 1 = \dfrac{1}{3}(x + 2)\\\\y - 1 =\dfrac{1}{3}x + \dfrac{1}{3}*2\\\\y=\dfrac{1}{3}x+\dfrac{2}{3}+1\\\\y=\dfrac{1}{3}x +\dfrac{2}{3}+\dfrac{3}{3}\\\\y=\dfrac{1}{3}x +\dfrac{5}{3}[/tex]

The location of the vertex Q after the dilation is (-2,-2). What is the location of vertex M after the dilation?
Answers
The location of vertex M after the dilation by a factor of 1/4 is at (-4, 3)
Dilation is a way of moving an object from a point on a plane to another location.
From the diagram attached, the coordinate of the vertex Q is at (-8, -8).
If the vertex Q after the dilation is (-2,-2), this means that the original coordinate is dilated by a factor of 1/4.
The vertex of coordinate M from the diagram is (-16, 12). Dilating the coordinate using a scale factor of 1/4 will give;
M' = (-16/4, 12/4) = (-4, 3)
Hence the location of vertex M after the dilation is at (-4, 3)

Kylie is excited to learn how to ski. She went to Snowy Heights Mountain, rented a pair of skis for $35, and took 5 hours of group skiing lessons. Kylie paid $175 in all. How much does Snowy Heights charge for each hour of group skiing lessons?
Answers
Answer:
5x + 35 = 175
$28
Step-by-step explanation:
She paid 35 for 1 pair of skis. She paid a certain amount(x) for 5 hours (5x + 35). Therefor making the expression 5x + 35 = 175.
Then, solve the equation with inverse operations.
5x + 35 = 175
Step 1: Subtract 35 from both sides.
5x = 140
Step 2: Divide 5 from both sides.
x = 28
Therefore, Kylie paid $28 each hour of the group skiing lessons.

Answer:
a. y = 2x + 1
b. 20
Step-by-step explanation:
a. With each increasing figure, two more blocks are added on. Through this, we can determine the rule:
y = 2x + 1
y being the total number of blocks in a figure
x being the number of the figure.
_________
b. To figure out which figure number has 41 squares, we can set the equation we found equal to 41.
41 = 2x + 1
40 = 2x
20 = x
So figure 20 will have 41 squares.

Answers
We want to find equations for the different markups for the manufacturer and the stores that sell the crayons.
We know that a pack of 24 crayons costs $0.05 to make.
Is sold to stores for $0.25
The stores sell it for $0.50
Now we want to get the markup equation for the manufacturer, this is:
Markup = 100%*(price - cost)/(cost) = 100%*($0.25 - $0.05)/$0.05 =400%
For the store it is:
Markup = 100%*($0.50 - $0.25)/($0.25) = 100%
For the composition of these two I assume you refer to the total markup (notice that these are not functions, we can't make a composition if we do not have a variable).
Comp = 100%*($0.50 - $0.05)/($0.05) = 900%
