Answer:

3:2 is equal to 12:8 and 12:8 is not 9:8

Step-by-step explanation:

Ratios are also fractions

3/2 is also 12/8

12/8 is not 9/8

Simplify (3x + 5) + (2x - 9) - (4x + 3
Law Incorporation [45]
If you would like to simplify (3 * x + 5) + (2 * x - 9) - (4 * x + 3), you can do this using the following steps:

(3 * x + 5) + (2 * x - 9) - (4 * x + 3) = 3 * x + 2 * x - 4 * x + 5 - 9 - 3 = 1 * x - 7 = x - 7

The correct result would be x - 7.

What the answer to this equation be?
scoray [572]

If you expand the square, you have

\dfrac{1}{4}x^2-3x=7x+8-10x

Simplify the right hand side:

\dfrac{1}{4}x^2-3x=-3x+8

Cancel the -3x appearing on both sides:

\dfrac{1}{4}x^2=8

Multiply both sides by 4:

x^2=32

Consider the square root of both terms (using the doubles sign):

x=\pm\sqrt{32}=\pm4\sqrt{2}

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°

Which one is correct? A,B,C, or D?
Paladinen [302]

Answer:

B

Step-by-step explanation:

3x-7 <-4

Firstly solve this.

+7 +7

3x<3

÷3 ÷3

x<1

And because the inequality symbol isn't "equal to", the circle isn't coloured in.

The line will go from 1 to behind 0
