Answer:

Step-by-step explanation:

Part A:

For Dog walking, he earns $30 for 5 hours of work.

He earns $36 for 6 hours of work.

$30/5 hours = $6/hour

$36/6 hours = $6/hour

He earns $6/hour dog walking.

For 8 hours, he earns 8 hours * $6/hour = $48

To earn $66, he works 66/6 = 11 hours.

5 30

6 36

8 48

11 66

Part B:

He earns $7/hour for yard work, so multiply the number of hours by 7 to find the money he earns.

Table for yard work

Hours     Money

5             $35

6             $42

8             $56

Part C:

For 5 hours, he earns $35 for yard work and $30 as a dog walker.

$35 - $30 = $5

3

Step-by-step explanation:

Step-by-step explanation:

(k + 3) - (3k - 5) = k + 3 - 3k + 5       [expand the brack and simplify like terms]

                         = -2k + 8

Answer:

67°

Step-by-step explanation:

1. The final angle in the top triangle is : 70

The angles in a triangle add up to 180° so 74 + 36 = 110 and 180 - 110 = 70

2. Vertically opposite angles are equal so the angle opposite the one we just found is 70° as well

3. The angles in a triangle add up to 180° so 70 + 43 = 113 and 180 - 110 = 67

Therefore, ? = 67°

Answer:

^4+2x^3+x+2

Step-by-step explanation:

1. Combine exponents

(+2)(^2x+1)

(x+2)(x^3+1)

2. Distribute

x (x^3+1)+2(x^3+1)

x^4+x+ 2(x^3+1)

3. Solution is x^4 + 2x^3 + x+2

Answer:

$263.50

Step-by-step explanation:

Answer:

x can be any real number except -5 and 7

Step-by-step explanation:

x is in the denominator and denominator cannot be 0

so 6 - |x-1| cannot be 0

==> |x-1| cannot be 6

because it's absolute value, so

x-1 cannot be 6 & x-1 cannot be -6

which give us the answer x cannot be 7 and x cannot be -5

so the answer is x can be any real number except -5 and 7

Answer:

a) m + 1000

b) m/2

c) 2(m + 1000)

Step-by-step explanation:

Answer:

46.15%

Step-by-step explanation:

# of girls + # of boys = total # of students

12+14=26

# of girls / total # of students = percentage of girls in the class

12÷26=0.461538

Move the decimal place over two spots or multiply by 100 for the percent

46.1538%

Round up if needed, in this case I rounded up to the hundredths place.

Answer:

f(-1) = 2

f(0) = 3

Step-by-step explanation:

f(a) = 3a - a²

f(4)= 3*4-4²= -4 ⇒ correct

f(3)= 3*3-3²= 0 ⇒ correct

f(-1) = 3*(-1)-(-1)²=-3+1= -2 ⇒ incorrect

f(0) = 3*0-0²= 0 ⇒ incorrect

f(-5) = 3*(-5)-(-5)²= -15-25= -40 ⇒ correct

Hi there!

I believe your answer is:  

[tex]m\angle A = 32\textdegree[/tex]

Here’s why:  

⸻⸻⸻⸻

∠A and ∠C should be vertical angles. This means that their measurements are the same.

⸻⸻⸻⸻

[tex]4x - 8 = 2x + 12\\\rule{150}{0.5}\\\rightarrow 4x - 2x - 8 = 2x - 2x + 12\\\\\rightarrow 2x -8 = 12\\\\\rightarrow 2x - 8 + 8 = 12 + 8 \\\\\rightarrow \boxed{x = 10}[/tex]

[tex]\rule{150}{0.5}\\\rightarrow m\angle A = 4(10)-8 \\\\\rightarrow m\angle A = 40 - 8\\\\\rightarrow m\angle A = \boxed{32}[/tex]

Hello!

Let's distribute the parenthesis

Solve:

Now, we can rearrange the variable so that x is on one side and the numbers are on the other.

We can isolate x by dividing by the coefficient of x (2).

The value of x is 10.

Answer:

hope this helps :)

Step-by-step explanation:

20−3x=5

Subtract 20 from both sides.

20-3x-20=5-20

⇒-3x=-15

divide both sides by 3

⇒-3x/-3=-15/-3

⇒x=5

Answer:

[tex] \sf \: d) \: x = 5[/tex]

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ 20 - 3x = 5

Then the value of x will be,

→ 20 - 3x = 5

→ -3x = 5 - 20

→ -3x = -15

→ 3x = 15

→ x = 15 ÷ 3

→ [ x = 5 ]

Hence, the value of x is 5.

Answer:B, C and E

Step-by-step explanation:

0.8 = 8 tenths

0.03 = 3 one hundredths

80/100 is the same as 8/10 or 8 tenths

3/100 is also 3 hundredths

This can be expressed by 8/10 and 3/100

Using the mean concept, it is found that the lowest possible average temperature on Wednesday, in degrees Fahrenheit, is of 72.

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem, there are 3 observations, given by: 62, 58 and x.

The mean is of at least 64, hence:

[tex]\frac{62 + 58 + x}{3} \geq 64[/tex]

[tex]120 + x \geq 192[/tex]

[tex]x \geq 72[/tex]

The lowest possible average temperature on Wednesday, in degrees Fahrenheit, is of 72.
