Answer:
x = 9
Step-by-step explanation:
Distribute
2x+2*5=3x+1
2x+10=3x+1
Subtract 3x from both sides
-x+10=1
Subtract 10 from both sides
-x=-9
Multiply both sides by -1
x=9
Answer: x=9
Step-by-step explanation: 2(x + 5) = 3x + 1
2(x+5)
2x+2(5)
2x+10-10= 3x + 1-10
2x-3x=3x-9-3x
-x/-1=-9/-1
x=9
For the expression 6 + y - 3, determine the coefficient for the variable term.
A -3 B 0 C 1 D 6
Explanation:
Think of 6 + y - 3 as 6 + 1y - 3
y and 1y are the same thing because 1 times any number is that same number.
The coefficient is the number to the left of the variable, so the coefficient is 1.

Answer:
X = 119, Y = 61, Z = 119
Step-by-step explanation:
These are supplementary angles and equal 180.
180 - 61 = 119
Opposite angles are congruent
-3x + y = -14
x= -2y + 14
Which variable should an expression be substitute for?
9514 1404 393
Answer:
x
Step-by-step explanation:
There is already an expression given for x, so that is the easiest variable to substitute for.
Substituting for x using the second equation, you have ...
-3(-2y+14) +y = -14
6y -42 +y = -14
7y = 28
y = 4
x = -2(4) +14 = 6
The solution is (x, y) = (6, 4).
_____
Substitution for x is the easiest.
__
The first equation could be rearranged to give an expression for y:
y = 3x -14
Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.

You rent an apartment that costs $800 per month during the first year, but the rent is set to go up $170 per year. What would be the monthly rent during the 8th year of living in the apartment?
The monthly rent during the 8th year of living in the apartment will be $2160.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.
Then the monthly rent during the 8th year of living in the apartment will be
Let y be the monthly rent and x be the number of years.
Then we have
y = 170x + 800
The rent after 8 years, then the rent will be
y = 170 × 8 + 800
y = 1360 + 800
y = $ 2160
Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.

19 3/7 - 12 6/7
Plz show how u got your answer
Answer:
16 4/7
Step-by-step explanation:
First, you cant subtract 3/7 from 6/7 so take 1 from 19, which turns it to 18. And add that one to 3/7 to get 10/7, or just add 7 to your numerator. So now you have 18 10/7 - 12 6/7. so subtract 18 - 12 to get 6, and the subtract 10/7 - 6/7 to get 4/7. You dont actually have to subtract the denominator just the numerators, because the denominatos are the same so you leave them just the way they are. I hope this helps :)

Answer:
a. m<DAB = 36°
b. m<B = 54°
c. m<C = 74°
Step-by-step explanation:
a. m<DAB = m<CAB + m<CAD
m<DAB = 20° + 16° (substitution)
m<DAB = 36°
b. m<B = 180° - (90° + m<DAB)
m<B = 180° - (90° + 36°) (substitution)
m<B = 54°
c. m<C = 180° - (90° + m<CAD)
m<C = 180° - (90° + 16°) (substitution)
m<C = 74°

High-definition televisions have an aspect ratio of 16: 9. The following answer choices are television screen sizes rounded to the nearest inch. Which could be a High-definition television?
Answer:
18.5 in approx
Step-by-step explanation:
Given data
aspect ratio of 16: 9
L= 16in
W= 9 in
We want to find the diagonal of the TV
applying Pythagoras theorem
d^2= l^2+w^2
d^2= 16^2+ 9^2
d^2=256+81
d^2= 337
d= √337
d= 18.35 in
Hence the tv is 18.5 in approx
helpppppp do i plug 7 in or still one? WILL MARK BRAINLIST
Answer:
154
Step-by-step explanation:
The expression is [tex]f(x)=4x^2-7x+7[/tex] and we know that [tex]f(x)=f(7)[/tex]. Therefore, you will have to substitute x with 7.
Calculations:
[tex]f(x)=4x^2-7x+7[/tex]
[tex]f(7)=4(7)^2-7(7)+7[/tex]
[tex]4(49)-49+7= 154[/tex]
Answer:
I think that you need to plug 7 in to the x's
Step-by-step explanation:
Yes it looks very weird, but if you don't think that is right, Use the 7 for the F's.
One of them should come out right. :3
