Answer: X = -3

Explanation: subtract 8 from both sides to be left with -4x = 12, then divide both sides by -4 to isolate x which would leave you with X = -3

Hope that helps!

Estimate the quotient by rounding each number to the nearest whole number. 33.7/ 9.5
GrogVix [38]

Answer: 34/10=3.4 The estimated quotient is 3.4

Step-by-step explanation: Basically,  you are dividing 33.7 by 9.5, but first you will need to round to the nearest whole number. A whole number does not contain a decimal. 33.7 rounded to the nearest whole number is 34. 9.5 rounded to the nearest whole number is 10. So, you are dividing 34 by 10.  34 divided by 10 is 3.4.

How do you solve this? If you can answer on paper
ser-zykov [4K]

Answer:

∠?=40°

Step-by-step explanation:

Remember that in a line AND a triangle there are <u>180 degree</u>s.

You correctly found the third angle in the left triangle to be 69°, Now plug it into the equation for a line, including 71°:

<u>69°+71°+x=180°</u>

1) Combine the degrees:

140°+x=180°

2) Subtract 140° from both sides:

x=40°

We have now found the bottom left angle for the triangle on the right to be 40°

To find the angle labeled "?" You must plug in all of the known angles of the triangle to be equal to 180°:

40°+100°+x=180°

1) Combine the degrees:

140°+x=180°

2) Subtract 140 from both sides:

∠?=40°
