Help. Math Got Me Super Stumped

Answer:

x=-1

Step-by-step explanation:

I'm weird and love these types of problems.

Ok first off we need to get x alone. To do that we need to first get rid of the 7.

We can do that by adding it because you have to use the opposite operation to get rid of it.

5x - 7 (+7) = -12 (+7)

See if you add -7 + 7 you get 0 which is why you have to use the opposite.

5x = -5

To get x alone you have to divide 5 because 5 is being multiplied by x.

5x(/5) = -5(/5)

x= -1

So x= -1

If you ever need more help, don't be afraid to reach out. I hope that helps!

Find angles a, b and c? <br> Please help.
laiz [17]

Answer:

B=112 degrees A=68 degrees and C=68 degrees

Step-by-step explanation:

the opposite angle of the 112-degree angle is the angle on the top left of the page, this means both of the angles are the same. You can then tell that that angle is the same as the one across from it because it shows on the page.  You can then figure out the opposite angle which is B so that means angle B is equal to 112 degrees. To figure out angle A you can just do 180 minus the angle B which is 112 degrees. You now know angle A which is 68 degrees, now to find the angle C you just have to notise that angle C is the opposite angle of angle A. This means that algle C is also 68 degrees.

Your race car weighs 1.5 tons. To make the car faster, you replaced the steel body with carbon-fiber and reduced the weight by 3
Elenna [48]
1.5 tons = 3000 pounds (because 1 ton is 2000 pounds)
Subtract 300 pounds, and you get 2700 pounds.
