Step-by-step explanation:
(a)
9n = [tex]\frac{15}{7}[/tex] - 2 ( multiply through by 7 to clear the fraction )
63n = 15 - 14 = 1 ( divide both sides by 63 )
n = [tex]\frac{1}{63}[/tex]
(b)
[tex]\frac{1}{3}[/tex] = k - 4 ( multiply through by 3 to clear the fraction )
1 = 3k - 12 ( add 12 to both sides )
13 = 3k ( divide both sides by 3 )
[tex]\frac{13}{3}[/tex] = k
(c)
g - [tex]\frac{2}{5}[/tex] g = 3 ( multiply through by 5 to clear the fraction )
5g - 2g = 15
3g = 15 ( divide both sides by 3 )
g = 5
(d)
[tex]\frac{3}{7}[/tex] w + 2w = 3 ( multiply through by 7 to clear the fraction )
3w + 14w = 21
17w = 21 ( divide both sides by 17 )
w = [tex]\frac{21}{17}[/tex]

What expressions are equivalent to 6.7 - (-2.5)
Answer:
[tex]6.7-\left(-2.5\right)=9.2[/tex]
Step-by-step explanation:
Given the expression
[tex]6.7-\left(-2.5\right)[/tex]
Solving the expression to get the equivalent function
[tex]6.7-\left(-2.5\right)[/tex]
[tex]\mathrm{Apply\:rule}\:-\left(-a\right)=a[/tex]
[tex]=6.7+2.5[/tex]
[tex]\mathrm{Add\:the\:numbers:}\:6.7+2.5=9.2[/tex]
[tex]=9.2[/tex]
Thus,

question is in the picture
Answer:
The second and fourth options
Step-by-step explanation:
A function is where one the inputs have only one output. In this case all we have to do is look at the x value (x,y) and see when it goes 1,2,3,4 and that means there are no repeating x and in that case each input has only one output. If you look at the other ones they have a repeating x and that means the input has two outputs and therefore it isn't a function.

the length of a rectangle is 4 meters less than twice its width. The area of the rectangle is 70. Find the dimensions of the rectangle
Answer: The width is 7 meters. The length is 10 meters.
Step-by-step explanation: Area = Length × width
Length is 2w - 4
Substitute that value for length, then solve for w.
70 = w(2w - 4)
70 = 2w² - 4w reorganize to quadratic equation form
2w² - 4w -70 = 0 These are All even numbers; factor out 2 (divide all by 2)
w² - 2w - 35 = 0 factor this
(w - 7)(w + 5) set each factor = 0 and calculate the value of w.
w+5=0 w= -5 (disregard this one because dimensions of real rectangles can't be negative)
w - 7 = 0 w = 7 The width is 7
Substitute into the original expressions to get the value of Length.
2(7) -4 = L 14 - 4 = L The Length is 10.
Check by substituting into the original equation:
w × 2w -4 = 70
7 × 2(7) -4 = 70
7 × 10 = 70 TRUE!
w
Dimensions of the rectangle are length=10 meter and width= 7 meter
What is Rectangle?A rectangle is a quadrilateral with four right angles.
Given,
The length of a rectangle is 4 meter less than twice its width
Consider,
l is the length of the rectangle
w is the width of the rectangle
l=2w-4
Area of the rectangle = Length × Width
70=l × w
Substitute the value of l is the second equation
70=(2w-4)×w
[tex]2w^{2} -4w=70\\2w^{2} -4w-70=0[/tex]
Take 2 outside
[tex]2(w^{2}-2w-35)=0\\ w^{2} -2w-35=0\\(w+5)(w-7)=0[/tex]
w=7,-5
Hence w wont be negative value
Therefore w=7 meter
Then,
l×w=70
[tex]l=\frac{70}{7}\\[/tex]
l=10 meter
Hence, the dimensions of the rectangle are length=10 meter and width= 7 meter

Aldo made a shirt using 1/5 meters of yellow fabric and 2/3 meters of red fabric. How many meters of fabric did he use in all? Write your answer as a fraction in simplest form.
Answer:
Aldo's shirt was made of 13/15 meters of fabric.
Step-by-step explanation:
We need to add these fractions. However, in order to do so, we need to find the LCM, which in this case, is 15.
1/5 + 2/3 =
3/15 + 10/15 =
13/15
This fraction is also written in simplest form. Therefore, Aldo's shirt was made of 13/15 meters of fabric.

Leah would like to earn at least $120 per month. She babysits for $5 an hour and works at an ice cream shop for $10 per hour. Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop.
This question is incomplete
Complete Question
Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $10 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y
represent the number of hours Leah works at the ice cream shop.
Answer:
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120
Step-by-step explanation:
Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop. Leah cannot work more than a total of 20 hours per month.
Hence:
x + y ≤ 20 ...... Equation 1
Leah would like to earn at least $120 per month.
She babysits for $5 an hour and works at an ice cream shop for $10 per hour.
Hence, out Equation is given as:
x × $5 + y × $10 = $120
5x + 10y ≥ 120..... Equation 2
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
To find x and y:
x + y = 20
x = 20 - y
5x + 10y = 120
Substitute: 20 - y for x
5(20 - y) + 10y = 120
100 - 5y + 10y = 120
Collect like terms
- 5y + 10y = 120 - 100
5y = 20
y = 20/5
y = 4 hours
Note:
x = 20 - y
x = 20 - 4
x = 16 hours
Hence:
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120
