Answer: 3n+21
Step-by-step explanation: it’s the distributive property so you multiply the number outside the parentheses times the numbers or number inside the parentheses
Answer:
3n+21
IF the question required =0 then move the 21 to the other side
and divide both sides by 3 and x would equal to -7
Step-by-step explanation:
3(n+7)
use the distributive property, so multiply 3 with n and 7
3n+21

(ex. 1 + 11 = 12, so (1, 11) is a solution)
Answer:
2+10=12
3+9=12
4+8=12
5+7=12
6+6=12

i'm little confused on this
Answer:
x = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x
Now, you have 8x - 1 + 3 = 7
Seperate the 8x from the other numbers
8x = 1 - 3 + 7 ---> 6
8x = 6
Now simplify
x = [tex]\frac{6}{8}[/tex] <----- to reduce, divide the numerator and denominator by 2
Hence,
x = [tex]\frac{3}{4}[/tex]
X + 9 =20 x=___ help
Answer:
x = 11
Step-by-step explanation:
x + 9 = 20 (Subtract 9 from both sides)
x = 20 -9
x = 11
Verify:
11 + 9 = 20 (Correct)

Answer:
A. exponential; constant % rate of change
Step-by-step explanation:
Each round has 50% of the players of the previous round, so the rate of change is a constant percentage. That makes the function a decaying exponential function, matching choice A.

20y-10x=5 in slope intercept form can you explain the steps
Given:
The equation is
[tex]20y-10x+5[/tex]
To find:
The slope intercept form of the given equation.
Solution:
The slope intercept form of a linear equation is
[tex]y=mx+b[/tex]
Where, m is slope and b is the y-intercept.
We have,
[tex]20y-10x=5[/tex]
We need to isolate y. Add 10x on both sides.
[tex]20y-10x+10x=5+10x[/tex]
[tex]20y=5+10x[/tex]
Divide both sides by 20.
[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]
[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]
[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]
[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]
Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].
Find the equation of a line which is parallel to y= 2/5 x + 17 and passes through (-15,12)
Answer:
y = 2/5x + 18.
Step-by-step explanation:
The line will have the same slope of 2/5.
Using the point-slope form of a line:
y - 12 = 2/5(x - -15)
y - 12 = 2/5(x + 15)
y = 2/5x + 6 + 12
y = 2/5x + 18.
Answer:
y = (2/5)*x + 18
Step-by-step explanation:
Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .
Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y = (2/5)*x + 18.
If longest out of a triangle is 3 inches longer than the shorter side. The medium size is 2 inches longer than the shorter side. If the perimeter is 26 inches, what are the length of the three sides
Answer:
Shortest side = 7 inches.
Medium side = 9 inches.
Longest side = 10 inches.
Step-by-step explanation:
Let the shortest side be x.
Translating the word problem into an algebraic equation, we have;
Shortest side = x
Medium side = x + 2
Longest side = x + 3
The perimeter of a triangle is given by the addition of all its three (3) sides.
Mathematically, the perimeter of a triangle is given by the formula;
[tex] P = A + B + C [/tex]
Substituting into the equation, we have;
26 = x + x + 2 + x + 3
26 = 3x + 5
3x = 26 - 5
3x = 21
x = 21/3
x = 7 inches.
Therefore, the length of the three sides are;
Shortest side = x = 7 inches.
Medium side = x + 2 = 7 + 2 = 9 inches.
Longest side = x + 3 = 7 + 3 = 10 inches.
A rectangular prism has a length of 5 cm, a width of 2 cm, and a height of 1 cm.

Select each correct answer.
O 5.2.1
12.1
o 1}(5+2)
o (123•15)
Answer:
The first two options
Step-by-step explanation:
The formula is V= l x w x h So that is why the first one works.
The second one works because of the commutative property of multiplication which says that the number don't have to be in a certain order so They multiplied the first 2 numbers which equals 12 1/2 which means 12 1/2 x 1/2 would work

Diana bought a total of 22 items including boxes of pizza and sodas for an upcoming event. Each box of pizza cost $8 and each soda cost $1.50. If Diana spent a total of $137, which of the following is a true statement?
A. Diana bought 16 boxes of pizza.
B. Diana bought more sodas than boxes of pizza.
C. Diana bought 6 boxes of pizza.
D. Diana bought an equal number of sodas and pizzas
Answer:
B. I think
Step-by-step explanation:
1.50 times 86 equals 129 witch would mean Diana bought 86 sodas
8 is equal to 1 pizza so Dianna could have bought 1 pizza
86>1
8+129 is 137 so I think the answer is B.
