Answer: x = − 10
Step-by-step explanation:
X − 8 = − 20 =
12 − 28 = − 16
28 = − 16
2 − 12 = − 10
x = − 10
Simplify 4x + 5y - 13xy - x - 2y
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]

Solve for n.
d=2m +3n
Answer:
n= 1/3d - 2/3m
Step-by-step explanation:
d=2m+3n
Step 1: Flip the equation.
2m+3n=d
Step 2: Add -2m to both sides.
2m+3n+−2m=d+−2m
3n=d−2m
Step 3: Divide both sides by 3.
3n/3 = d-2m/3
Therefore
n= 1/3d - 2/3m
Hope this helps!
Plz name brainliest if possible.
Answer:
n = d - 2m
3*
Step-by-step explanation:
First we want to get n alone on one side, so we should subtract 2m from both side;
d = 2m + 3n
3n = d - 2m
Now to get n by itself, we need to divide by 3 from both sides;
3n = d - 2m
n = d - 2m
3*
*Pretend there is a fraction bar between d - 2m and 3
the difference between objects being "similar" vs. "congruent
Answer: See below
Step-by-step explanation:
The difference between similar and congruent is the size and shape.
If two objects are similar, they look similar to each other, meaning they look the same, but not exactly the same. It can be 2 stuffed animals that look the same, but different sizes. One can be large and other can be small.
If two objects are comgruent, you know that they are EXACTLY the same. They are the same size, shape, etc. Using the example from above, you have either two large stuffed animals, or two small stuffed animals. The two large animals would be congruent to each other, same for the small animals.
Congruent means that they are identical. They are exactly the same in every way.
Similar can mean they look the same but they are not identical.
For example, a triangle that has been scaled down in size is still similar to the original triangle but they are not congruent.
I believe thats what it is.
Solve the equation.

Answer:
No Solution
Step-by-step explanation:
There are no values of x that make the equation true.
solve for Y!!!!!!!
12x+16y=96
12x + 16y = 96
Subtract 12x from both sides
16y = 96 - 12x
Divide each side by 16
y = 6 - 0.75x

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

Find the weekly wages for a person who earns $12 an hour and worked 8 hours from Monday through Sunday
Answer:
$672 per week.
Step-by-step explanation:
12x8 = 96
96x7 = 672
Answer:
$665 per week
Step-by-step explanation:
first you do 12*8 to see how much money the person gets per day, which would be 96 dollars per day. then, multiply 96 by 7, to calculate how much the person gets per week, which is $665 per week if this helped plz plz plz give me brainliest :D
Expand.
If necessary, combine like terms.
(2x + 5)(x – 5) =
To Expand: (2x + 5)(x - 5).
(2x + 5)(x - 5)
= 2x(x - 5) + 5(x - 5)
= 2x² - 10x + 5x - 25
= 2x² - 5x - 25 Ans.
(Combined the like terms)
Answer:
2x² - 5x - 25
Step-by-step explanation:
Use FOIL method
(2x + 5)(x - 5) = 2x*x + 2x*[-5] + 5*x + 5*[-5]
= 2x² -10x + 5x - 25 {add like terms}
= 2x² - 5x - 25
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'
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!

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
