Alexxx [7]3 years ago

Answer:

7. x = 4

8. x = 10

Step-by-step explanation:

7. The angles are equal to each other so you can do

40 = 12x - 8

48 = 12x

4 = x

8. The angles add up to be 180 degrees so you can combine them and set them equal to 180

6x + 12x = 180

18x = 180

x = 10

Ty needs to cut strips of wrapping paper that are each 9 inches wide. if Ty has 2 rolls of wrapping paper that are each 15 feet
stiks02 [169]
Find the total length in inches of one of the rolls:
15*12=180 inches.

Now multiply the length of one roll (180 inches) by 2 to find the total length:
180*2=360 inches.

Divide by the width of the strips to find the total number of strips:
360/9=40 strips

Answer:

c = 160 - 3(45)

Step-by-step explanation:

if c = the number of characters left;

160 = maximum number of characters that can be used in a text

3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)

(# of char left) = (max # char) - (# char already used) so:

c = 160 - 3*(45)

c = 160 - 135

c = 25

Mollie watches a film that lasts 130 min it begins at 6:15 pm. What time did it end?
Natalka [10]
Answer:

Starts at 6:15

Note: An hour is 60 minutes.

So an hour after 6:15 is 7:15 and an hour after that is 8:15. Now just add another 10 minutes and you get 8:25.

So the film ended at 8:25.

The graph for the equation y=-2x+1 is shown below.
Tpy6a [65]

Answer:

Step-by-step explanation:

Given the equation y=-2x+1 and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect. Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel. To have this result, we must have that they have the same slope but different y intercept. That is take m = -2 and b any value different to +1. For example, the b = 6. So

y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.
