I need help. i’m failing geometry

Answers

Answer 1

4x +7 =12x-1
-7 from both sides
4x=12x-8
-12x from both sides
-8x=-8
x=1
for y
y+1=3y-11
-1 from both sides
y=3y-12
-3y from both sides
-2y=-12
y=6

Answer 2

Answer:

x = 1 and y = 6

Step-by-step explanation:

so the opposite sides are equal to each other, therefore

4x + 7 = 12x - 1

and y + 1 = 3y - 11

so for the xs

start by adding 1 to each side

4x + 8 = 12x

subtract 4x from both sides

8=8x

divide by 8

x=1

for the ys

subtract one from each side

y= 3y -12

subract 3y from each side

-2y=-12

divide by -2

y=6

Choose the triangle in which angle 2 is not an exterior angle.
help me...new freinds?

Answers

Answer:

The third triangle

Step-by-step explanation:

The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.

So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.

The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.

The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.

The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.

Hope this helps! Feel free to ask any questions! :)

A toll road company has two plans for customers. One plan charges $10 per month for rental of a transponder (a box that identifies your car on the toll roads) plus $0.60 per mile driven. The second plan does not require that you rent a transponder. Instead, it charges customers $0.75 per mile driven on the toll road. Find the minimum number of miles you would need to drive in a month to make the first deal a better deal.

Answers

Answer:

The minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

Step-by-step explanation:

For the first deal to be a better deal it has to cost less than the second plan and you can write an equation in which the first plan has a lower cost than the second one:

10+0.60m<0.75m, where:

m is the number of miles driven

Now, you can solve for m:

10<0.75m-0.60m

10<0.15m

10/0.15<m

m>66.6

According to this, the answer is that the minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.
