what is 2x-15+21= -18
Answer:
2x - 15 +21 = -18
2x + 6 + 18 = 0
2x + 24 =0 ...it is a linear equation
if u want to solve for X then..
2x = -24
X = - 24
2
X = -12
a rectangle has a length of 25x^3 and a width of 5x^2. Fkns the area.
Answer:
Step-by-step explanation:
I hope you want the area.
Area = L * W
L = 24x^3
W = 5x^2
Area = 24x^3 * 5x^2
Area = 120 * x^(3 + 2)
Area = 120 * x^5
Note
When you multiply numbers or letters that have powers, if the base for both of them is the same, the powers are added.
The above answer is an example x^2 * x ^3 are letters (x) that are raised to the 2nd power and the 3rd power. You add the powers.
Numbers can do the same thing

Solve the following system of equations by substation.
5y = 7x + 22
x = -6y + 17
A. (2,-1)
B. (5,3)
C. (-1,3)
D. (-1,4)
Answer:
C. (-1, 3)
Step-by-step explanation:
Label the 2 equations:
5y= 7x +22 -----(1)
x= -6y +17 -----(2)
Substitute (2) into (1):
5y= 7(-6y +17) +22
5y= -42y +119 +22 (Expand bracket)
5y= -42y +141 (Simplify)
42y +5y= 141 (+42y on both sides)
47y= 141
y= 141 ÷47 (÷47 on both sides)
y= 3
Substitute y= 3 into (2):
x= -6(3) +17
x= -18 +17
x= -1
Thus, the solution is (-1, 3).

Answer:
x(3 + 4)
4(3x + 1)
Step-by-step explanation:
3x + 4x
The common factor is x, so factor out the x.
3x + 4x = x(3 + 4)
12m + 4
The common factor is 4, so factor out the 4.
12m + 4 = 4(3x + 1)

Greatest Common Factor (GCF) and Lowest Common Multiple (LCM) of (40, 42) ASAP Please
Answer:
the gcf for 40 and 42 is 2
and lcm for 40 and 42 is 840
Step-by-step explanation:
the factors of 40 are 1,2,4,5,8,10,20,40 ; the factors of 42 are 1,2,3,6,7,14,21,42 .
So what they have in common for GCF is 2 for a factor .
multiples of 40: 40, 80, 120,160,200,240,etc.
multiples of 42 : 42, 84,126,168,210,252,etc.
What they have in common for LCM is a multiple is 840

In the equation y = kx, what does the variable k represent?
A. The dependent variable
B. The constant of variation
C. The independent variable
D. The direct variation equation
Answer:
I think it B but I really don't know cause need like an example
The k in the equation represents Option B) The constant of variation
What is a constant in an equation?A constant is a value or number that never changes in expression; it's constantly the same. For example, 36 and 82 are constant because its face value is 36 and 82 respectively. Its value never changes.
Given here the equation y=kx where k is the slope and a scalar value thus it is independent of x and y and thus is a constant.
Hence, The k in the equation represents Option B) The constant of variation

Solve please. 20 points.
Answer:
336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
336 cm^2
A computer store changed the price of a laptop. It was originally $900, but now it is $1,100.Find the percent of change
Answer:
The percent of change is 22.22%.
Step-by-step explanation:
You can calculate the percent of change by subtracting the original number from the final number and dividing that by the original number. Then, you have to multiply the result for 100:
percent of change=((1,100-900)/900)*100
percent of change=(200/900)*100
percent of change=22.22%
According to this, the answer is that the percent of change is 22.22%.
Which statement about the data is true
Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean.
Step-by-step explanation:
A is wrong, because the standard deviation is +/-0.15 (the measure up or down from the mean)
B is wrong, because the mean is exactly 0.5
C is wrong, because 1 standard deviation up from the mean is 0.65, and 0.7 is outside of that.
