Answer:

B. 40

Step-by-step explanation:

Angle C is linear with ACD, so the 2 angles = 180 degrees. 180 - 155 = 25.

All 3 angles need to add to 180, so 115 + 25 + angle B = 180

140 + angle B = 180, so angle B is 40 degrees.

Solve to find the value for x in the linear equation: 3(−4x + 5) = 12.1. Use the distributive property: 2. Use the subtraction p

Brrunno [24]

Answer:

$x =\frac{7}{12}$

Step-by-step explanation:

Given equation,

$3(-4x + 5) = 12$

Step 1 : Using distributive of equality,

$3(-4x) + 3(5) = 12$

Step 2 : simplify,

$-12x + 15 = 12$

Step 3 : Using subtraction property of equality,

$-12x = 12 - 15$

Step 4 : Simplify,

$-12x = -7$

Step 5 : Using division property of equality,

$x =\frac{7}{12}$

How do you know that the sum of 7-1g and 7-2 is rational?

user100 [1]

The sum of 7-1 and 7-2 will be a rational number because sum of rational numbers is a rational numbers.

A rational number is a number which can be written in p/q form where q≠0.

We know that when two rational numbers is added then the sum is also a rational number. And when two rational numbers are subtracted then the difference is also a rational number.

So in the given question, lets study the term differently that is,

i) 7 - 1 is a rational number because their difference is equal to 6 and it can be written in p/q form which is 6/1.

ii) 7 – 2 is also a rational number as their difference will be 5 which is a rational and can be written in p/q form which is 5/1.

So when these two rational numbers are added their sum will also be a rational number which is 11.

I'm struggling with this question i need help. please and thank you

The answer is 100X because if you do 5x-4x first it will be 1x. Later on, if you do the exponent you have 1x times 1x. Then you do 1x+9x = 10x

Then you do 10x times 10x because of the exponent is telling you how times you do it and it equals to 100x.

Answer= 100x

I hope this helps YOU!
