Answer:

12

Step-by-step explanation:

(-15)/(-18) = 10/x cross multiply expressions

-15x = -180 since both sides are negative we can write without the sign

15x = 180 divide both sides by 15

x = 12

Answer:

6

Answer:

She'll find 6 items in 3/4 of an hour.

Step-by-step explanation:

First, change 3/4 to 6/8. Then, do you 6/8 divided by 1/8 to get your answer of 6 items in 3/4 of an hour.

First Row:- 6

Second Row:- 1,3

Third Row:- 4,5,2

Sum of third Row:- 4+5+2=11

Answer:

y = 3x

Step-by-step explanation:

from the table slope or rate of change is

m = 6 - 0 / 2 - 0 = 6/2 = 3

m = 12 - 6 / 4 - 2 = 6/2 = 3

m = 18 - 12 / 6 - 4 = 6/2 = 3

so m = 3

y = mx + c

c is y intercept --> y value when x is 0

y = 0 = c

so line equation is y = 3x + 0

y = 3x

Answer:

B, or 3x.

Step-by-step explanation:

When looking at the x value (time), and the y value (distance), you can see that every time you multiply the x value by 3, you get the y value.

2 x 3 = 6

4 x 3 = 12

6 x 3 = 18

Therefore, your answer is 3x.

Answer: c. 80

Step-by-step explanation:

Answer:

80

Step-by-step explanation:

First add all of the the test results 70+70+80+90+90=400 then you divided by how many test their were so 400/5=80

Answer:

C. area = radius/2 × circumference.

Answer:

3

Step-by-step explanation:

Area can not = circumference without dividing it so 4 is wrong

Answer:

−27+7

Step-by-step explanation: First add 23x + 4x=27x

                                             Then subtract 54x gives you -27x

                                               You can't add a regular number with x's so your                                final answer is -27x+7

Answer:

−27x+7

Step-by-step explanation:

Answer:

Answer:

$1.58X12=$18.96

Step-by-step explanation:

6x + 50 = 62

6x = 62 - 50

6x = 12

x = 12/6

x = 2

Step-by-step explanation:i just guessed

Answer:

The y-intercept is where the graph intersects with (goes through) the y-axis.

Step-by-step explanation:

The point where the graph passes through the y-axis (vertical axis) is known as the y-intercept.

Answer:

The y intercept on a graph is the y-axis.

Step-by-step explanation:

Answer:

By substracting 0.16 from 0.35, we get 0.19. This is also true when we subtract 0.35 from 0.54. Thus, 0.19 is what we are adding to each previous term to get the next one. When we add 0.19 to 0.54, we get 0.73, and when we add 0.19 to 0.73, we get 0.92. Therefore, the next two terms in the pattern are 0.73 and 0.92.

Step-by-step explanation:

Answer:

0.73 and 0.92

Step-by-step explanation:

The difference of the first 3 is 0.19 per step, so continuing that is 0.73 and then 0.92

Step-by-step explanation:

Answer:

You can purchase 10 songs after buying 12 videos.

Step-by-step explanation:

Step 1 - Find out how much downloading a video costs. If the cost of a video download is 5 times as much as a song download costs, and a song download is $1, then you'd have to multiply 5 x $1, which equals 5. So downloading a video costs $5.

Step 2 - Find how much it costs to buy 12 videos by multiplying the cost of 1 video to how many you bought, 12. We already found out 1 video costs $5, so that would 12 x $5, which equals $60. That means those 12 video downloads costed you $60 dollars.

Step 3 - Find out how many songs you can buy with your remaining credit. If you already payed $60 dollars worth of videos, then you only have $10 dollars left to spend because $70 - $60 is $10. So if every song costs $1 dollar, then you'd be able to purchase 10 more songs until you reach your credit, $70 dollars.
