angle a and b are supplementary, The measure of Angle B is 10 degrees less than 4 times of the measure of A. What is the measure of Angle A?
Answer:
a=23°45'
Step-by-step explanation:
a+b=180°
b=a•4-10°
a+a•4-10°=180°
2a•4-10°=180°
2a•4= 190°
2a=190°/4
2a= 47°30'
a=47°30'/2
a= 23°45'

What is the solution to
-(6x+8)= 4(17 – x)?
Answer:
x=30
Step-by-step explanation:
Simplifying
6x + 8 = 4(x + 17)
Reorder the terms:
8 + 6x = 4(x + 17)
Reorder the terms:
8 + 6x = 4(17 + x)
8 + 6x = (17 * 4 + x * 4)
8 + 6x = (68 + 4x)
Solving
8 + 6x = 68 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
8 + 6x + -4x = 68 + 4x + -4x
Combine like terms: 6x + -4x = 2x
8 + 2x = 68 + 4x + -4x
Combine like terms: 4x + -4x = 0
8 + 2x = 68 + 0
8 + 2x = 68
Add '-8' to each side of the equation.
8 + -8 + 2x = 68 + -8
Combine like terms: 8 + -8 = 0
0 + 2x = 68 + -8
2x = 68 + -8
Combine like terms: 68 + -8 = 60
2x = 60
Divide each side by '2'.
x = 30
Simplifying
x = 30

I know the answer is .78, but don’t understand why? .9-.6X.2
Step-by-step explanation:
When you multiply 0.6 and 0.2, you do not get 1.2. Rather, the product would be 0.12.
We have the equation [tex]0.9-(0.6)(0.2)[/tex]
To show you what is happening, lets convert these numbers into fractions
This would give us [tex]\frac{9}{10} -(\frac{6}{10})(\frac{2}{10})[/tex]
Recall that when you multiply two fractions, you multiply the numerators and denominators separately. Doing so gives us
[tex]\frac{9}{10} -\frac{6*2}{10*10}[/tex]
Which then becomes
[tex]\frac{9}{10} -\frac{12}{100}[/tex]
The last thing we need to do is to create a common denominator
[tex]\frac{90}{100}-\frac{12}{100}=\frac{78}{100} =0.78[/tex]
Another way to see what is happening is by thinking about the numbers in scientific notation. Doing so would give us
[tex]9*10^{-1}-(6*10^{-1})(2*10^{-1})[/tex]
Once we multiply these terms, we get
[tex]9*10^{-1}-6*10^{-1}*2*10^{-1}\\\\9*10^{-1}-12*10^{-2}[/tex]
Now we can convert these numbers into decimals to get
[tex]0.9-0.12=0.78[/tex]

Which of the following values are solutions to the inequality 10+ x > 7?
I. – 7
II. - 1
III. - 3
Answer:
II
Step-by-step explanation:
All the other options create a number that is smaller than 7, while the inequality suggests otherwise.
While, II create the number 9 - which is indeed bigger then 7

Answer:
[tex]x=\frac{-3d-9}{k-d}[/tex]
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d
[tex]x=\frac{-3d-9}{k-d}[/tex]
Answer:
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d

What are the coefficients in this expression? 2x +9y+(-4) Select all that apply.
A 2
B 9
C 9y
D 2x
Answer: A and B
Step-by-step explanation:
Coefficient is the number or term that came before a variable.
If you can't understand this, I will provide some examples.
Coefficient in 3x is 3, 3 came before x which is a variable-------------------------------------------------------------------
2x + 9y + (-4)
2x: coefficient is 2
9y: coefficient is 9
-4: no coefficient, it is just a constant

help me!!!!!!!! Evaluate: 30 - 12÷3×2
Answer:
22
Step-by-step explanation:
30 - 12 :3 ×2
30 - 4 ×2
30 - 8
22
Answer:
22
Step-by-step explanation:
The order of operations states that 12÷3×2 (division and multiplication) is done first from left to right .
12÷3×2 = 4 × 2 = 8
Therefore , 30 - 12 ÷ 3 × 2 = 30 - 8 = 22.
So, the answer is 22. Hope this helps!
