Answer:

Basically, you need to plug 5 in as y

First, plug 5 in the place of Y 10 * 5 + 6

Then solve the equation from there.

10 * 5 = 50

50 + 6 = 56

Tammy must run more than 67 miles total to reach her fitness goals. She has already run 35 miles and runs 4 miles per day, Which
zhuklara [117]

Answer:

35 + 4x > 67

To reach her fitness goal, she needs to run for more than 8 days.

Step-by-step explanation:

She has already run 35 miles and runs 4 miles per day:

This means that after x days, the distance she will have run is:

D(x) = 35 + 4x

Tammy must run more than 67 miles total to reach her fitness goals.

This means that:

D(x) > 67

35 + 4x > 67

The inequality is:

35 + 4x > 67

Solution:

4x > 32

x > \frac{32}{4}

x > 8

To reach her fitness goal, she needs to run for more than 8 days.

44 points. find the surface area of the pyramid to the nearest whole number.
Furkat [3]

It would be 348

as A= lw+l((w /2)^2+h^2)^0.5+w((l /2)^2+h^2)^0.5

where l=12, w=12, h=6

A=347.65 ~ 348

A video game has 25 levels. At level one, a player has 5 points. Each additional level increases the player's points by 10. If
ozzi

Answer:

<u>B. (3,25)</u>

Step-by-step explanation:

x = level of the video game

y = number of points

At level 1, a player has 5 points.

At level 2, the player has 5 + 10 = 15 points

Therefore, we can use the function notation this way:

f(x) = 5x + 10

<u>The only ordered pair given that is from this function is:</u>

<u>B. (3,25)</u>

<u>f(3) = 5 * 3 + 10 </u>

<u>f(3) = 15 + 10 = 25</u>

The remaining three don't represent this function.

What is 2 5/6 +1 5/7
mylen [45]
Hi Cherise1cherhop lets break this equation down with these steps:

1) add the whole numbers first

2) find the LCD of the fractions and that would be 42 since 42 can go into both denominators through multiplication

3) make the denominators (bottom numbers) the same as the LCD (42)

4) simplify it, now the denominators are equal

5) join the denominators together

6) simplify it (3 + 65/42)

7) convert 65/42 to mixed fraction

8) now that we made it a mixed fraction, simplify it

Answer: 4 23/42
