Answer:
Multiple answers would work
Step-by-step explanation:
From the subtraction sign before the 18x, we can infer that one of the equations has a negative number. So, know we have this:
(x-?) (x+?)
There are multiple answers this could be,
(x-18) (x)
(x-20) (x+2)
You get where I am going...
If you went with the first on (x-18) (x), then you wouldn't have to add anything.
(x-20) (x+2) = x^2 - 18X - 40.
To be honest this one stumped me. Some just have multiple answers. My guess is that you have to fill out the boxes so maybe the first answer wouldn't work.
Sorry I couldn't give a concise answer. Though their probably is one obivious answer that I am missing.
Answer:
I think its 16, 32, or 36.
Step-by-step explanation:
Because I set it up like 2/100 = x/18 and then do the math

Solve for d

Answers
Given:
The equation is
[tex]-\dfrac{1}{4}d-\dfrac{2}{5}d=39[/tex]
To find:
The value of d.
Solution:
We have,
[tex]-\dfrac{1}{4}d-\dfrac{2}{5}d=39[/tex]
Taking LCM, we get
[tex]\dfrac{-5d-8d}{20}=39[/tex]
[tex]\dfrac{-13d}{20}=39[/tex]
Multiply both sides by 20.
[tex]-13d=39\times 20[/tex]
Divide both sides by -13.
[tex]d=\dfrac{39\times 20}{-13}[/tex]
[tex]d=-3\times 20[/tex]
[tex]d=-60[/tex]
Therefore, the value of d is -60.

Answers
Answer:
x = -0.4
Step-by-step explanation:
Given:
-9x + 0.4 = 4
To move all constant to the right side of the equation, perform subtraction operation
That is, subtract 0.4 from both sides of the equation
-9x + 0.4 - 0.4 = 4 - 0.4
-9x = 4 - 0.4
-9x = 3.6
Perform division operation to isolate the variable
That is, divide both sides by -9
-9x / -9 = 3.6 / -9
x = -0.4
Answer:
1 Subtract 0.4
2 Divide by -9 on both sides
3 -0.4

Answer:
-29
Step-by-step explanation:
replace the variables with the numbers provided. m = -4 so replace the m in the equation with -4:
3 - (-4)n
same thing with the n. n=-8 so replace the n in the equation with -8:
3 - (-4)(-8)
and then all you have to do after that is solve it using PEMDAS
multiply -4 and -8 first:
3 - 32
then solve 3-32 and you end up with -29.
what is 9 : 45 = 6 : ?
Answers
Answer:6:45
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
a ratio is just a fraction
9:45 = 9/45
6:x = 6/x
now you have 9/45 = 6/x
cross multiply:
9 * x = 45 * 6
9x = 270
divide both sides by 9
9x/9 = 270/9
x = 30

Answers
Answer:
Step-by-step explanation:
Simplifying
2x + -8y = 56
Solving
2x + -8y = 56
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '8y' to each side of the equation.
2x + -8y + 8y = 56 + 8y
Combine like terms: -8y + 8y = 0
2x + 0 = 56 + 8y
2x = 56 + 8y
Divide each side by '2'.
x = 28 + 4y
Simplifying
x = 28 + 4y
