-2(5) + 2 + 5(5) + 8

-10 + 2 + 25 + 8

25

Answer: 25

Answer:

The answer would be 25.

Step-by-step explanation:

If x=5, that means:

-2(5)+2+5(5)+8

-10+2+25+8

-8+25+8

-17+8

25

Therefore, the value would be 25.

Answer:

$13/hr

esa es la respuesta

Answer:

$13/hr

Step-by-step explanation:

Without bonus gross income = $350 - $51 = $299

Hours combined = 6hr + 8hr + 9hr = 23hr

23hr = $299

$299 ÷ 23hr = $13

Hourly pay rate = $13

Answer:

32.65

Step-by-step explanation:

Answer:

Total cost of purchase = $32.66

Step-by-step explanation:

$30.45 before tax

If sales tax = 7.25% or 0.0725, then: $30.45 × 0.0725 = $2.21

Add the sales tax of $2.21 to $30.45 = $32.657 or $32.66

Therefore, the total cost of his purchase is $32.66

Answer: 3.3

Step-by-step explanation: pythagorean theorem.

first we'll do the bottom triangle. a^2 + b^2 = c^2

a=3 and b=4

(3)^2 + (4)^2 = 9 + 16 = 25 which = c^2

to find c from c^2, square root the c^2 value. in this case it's 25. the square root of 25 is 5.

5 is now the base of the rectangle

now we can do pythagorean theorem again. except we'll switch it so it's c^2 - b^2 =a^2

c=6 and b=5

(6)^2 - (5)^2 = 36 - 25 = 11 = a^2

to find a we'll square root 11 which is just [tex]\sqrt{11[/tex]. approx. 3.3 to the nearest tenth.

We can use the Pythagorean theorem to solve for x.

But first, we have to find the value of 'a' (as I labelled in the diagram below). We could actually do all this in one step if we set it up correctly.

so    x = √(6² - a²)

&     a² = 3² + 4²

⇒  x = √[6² - (3² + 4²)]

    x = √(11)   or ≈ 3.3167

Answer:

the answer is c

Step-by-step explanation:

1 hour=60 minutes

60/6 minutes= 10

10 x 3 = 30 minutes

half hour= 30 minutes

30/6 = 5

5 x 3= 15 minutes

30 +15 = 45 minutes

Answer:

The x-intercept of the function is 4 which represents the total time of the trip, in hours.

Step-by-step explanation:

Since Skylar was a distance of 0 miles from City A after 4 hours, the x-intercept of 4 represents how many hours it took Skylar to drive from her house to City A.

Have a good day :)

The x- intercept is 4 hours.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δxwhere,m is the slope

Given:

D=120-30t.

According to slope - intercept form

y= mx+ b

where m is the slope and b is the y intercept.

So,  the x-intercept

0= 120- 30t

t= -120/ (-30)

t= 4

Hence, the x- intercept is 4 hours.

Hope this helps you if it does please mark brainliest

Step-by-step explanation:

the act of separating something into parts.

Answer:

2)  Lyn has 42, and Jo has 21

4)  320 women

6) 12 miles

Step-by-step explanation:

2) Divide 63 by 3 and get 21. 21 + 21 = 42 for Lyn, and leave 21 for Jo.

4) Subtract 20 from 620, and get 600. Divide 600 into 2 and get 300. 300 +20 = 320

6) Divide 24 into 2, and get 12. Multiply 12 by 3 and get 36. Divide 36 by 3 and get 12. 12 is your answer.
