Answer:
a = 6
Step-by-step explanation:
120 = 3 + 3(7a - 3) (by PEDMAS, expand parentheses first by distributive property)
120 = 3 + 7a(3) - 3(3)
120 = 3 + 21a - 9
120 = 21a - 6 (add 6 to both sides and rearrange)
21a = 120 + 6
21a = 126 (divide both sides by 21)
a = 126/21
a = 6
Step-by-step explanation:
120-(3+3*(7*a-3))=0

Simplify this expression (xy^4)^6
Answer:
x^6*y^24
Step-by-step explanation:
This will become:
[tex]x^6*(y^4)^6[/tex]
Next, multiply the exponents for y:
x^6 * y^24
So the answer is x^6*y^24
The vertex form of the equation of a parabola is y = 5(x-3)2 - 6.
What is the standard form of the equation?
9514 1404 393
Answer:
y = 5x² -30x +39
Step-by-step explanation:
Multiply it out and collect terms.
y = 5(x -3)² -6
y = 5(x² -6x +9) -6 . . . . . expand the square
y = 5x² -30x +45 -6 . . . . use the distributive property
y = 5x² -30x +39 . . . . . . collect terms
_____
The expansion of a binomial square is ...
(a +b)² = a² + 2ab + b²
In this problem, we have a=x, b=-3.
Answer:
y = 5x² -30x +39
the answer above me explains it better go look at it
Simplify the expression. 7d + 3 - 2d
Answer:
5d+3
Step-by-step explanation:
just as you combine regular numbers you can combine terms that have the same variable raised to the same exponent, and 7d-2d=5d. So the equation simplifies to 5d+3

The first night in a hotel costs 40 dollars. All additional nights cost 27 dollars. How many nights did we stay
at this hotel if the total bill was 148 dollars?
Answer:
5
Step-by-step explanation:
First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)
Answer:
4 nights
Step-by-step explanation:
148-40=108
108÷27=4
So, you spent 4 nights at the hotel.

What is the value of x in the equation below
6(x-8)=72
Answer:
x = 20
Step-by-step explanation:
6(x-8)=72
6x-48=72
6x-48+48=72+48
6x=120
6x/6=120/6
x = 20
hope it's helpful ❤❤❤❤❤❤
THANK YOU.

Answer: x=20
Step-by-step explanation:
Distribute the 6 to the values in the parentheses
6x - 48 = 72
Add 48 to each side
6x = 120
Divide each side by 6
x = 20
Two straight lines have equations y = p x + 4 y = p x + 4 and p y = q x − 7 p y = q x − 7 , where p p and q q are constants. The two lines meet at the point ( 3 , 1 ) ( 3 , 1 ) . What is the value of q q ?
Answer:
q = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The point of intersection (3, 1 ) is the solution to both equations
Using
y = qx - 7 and substituting x = 3, y = 1
1 = 3q - 7 ( add 7 to both sides )
8 = 3q ( divide both sides by 3 )
[tex]\frac{8}{3}[/tex] = q

Solve 8x – 5 = 23 + 4x.
Answer: X equals 7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
First you want to simplify the equation
8x + (-5) = 23 + 4x
-5 + 8x = 23 + 4x
Then solve for x, but before we do that we !!!must!!! move all terms that have x to the left. Everything else would go to the right.
So we add -4x to both sides ..
-5+ 8x + (-4x) = 23 + 4x + (-4x)
-5 + 4x = 23 + 4x + (-4x)
-5 + 4x = 23 +0
-5 + 4x = 23
Then add 5 to both sides of the equation:
-5 + 5 + 4x = 23 + 5
0 + 4x = 23 + 5
4x = 23 + 5
4x = 28
Then divide each side by 4:
x = 7
And there you have it. The answer is 7. Hope this helps! :)
-2(x-3)+4x = -(-x+1) SOLVE EQUATION AND SHOW STEPS ...NEED ANSWER NOW
Answer:
x=-7
Step-by-step explanation:
-2(x−3)+4x=−(−x+1)
Step 1: Simplify both sides of the equation.
−2(x−3)+4x=−(−x+1)
−2)(x)+(−2)(−3)+4x=x+−1(Distribute)
−2x+6+4x=x+−1
(−2x+4x)+(6)=x−1(Combine Like Terms)
2x+6=x−1
2x+6=x−1
Step 2: Subtract x from both sides.
2x+6−x=x−1−x
x+6=−1
Step 3: Subtract 6 from both sides.
x+6−6=−1−6
x=-7
)Elliot has been running a lawn care business since 2000. He cuts grass, trims, and weed whacks yards for his customers throughout the season. Each year, he has increased his fee by the same amount. The table shows what Elliot charged each customer for two given years of his business:
Year Lawn Care Fee
2000 $750
2010 $1350
A. What is the rate of change and initial value for Elliot’s business? How do you know?
B. Write an equation in slope-intercept form to represent the fees that Elliot charges each year.
Answer:
Rate of change = (1350 - 750)/(2010 - 2000) = 600/10 = $60
Initial value = $750
Equation is y = 60x + 750; where y is the amount charged to customer and x is the number of years from 2000.

Jake lives 2⅓mile from school. He decides to walk to the shop on his way home. The shop is 1⅜mile from school. A) What is the shortest possible distance from the shop to his home? B) What is the largest possible distance from the shop to his home?
Answer:
Shortest distance = 23/24
Farthest distance = 3 17/24 miles
Step-by-step explanation:
Distance of home from school = 2 1/3 miles
Distance of shop from school = 1 3/8 miles
Shortest distance possible :
(2 1/3 - 1 3/8) miles
(7/3 - 11/8) miles
L. C. M = 24
(56 - 33) / 24
23 / 24 miles
The farthest distance :
(2 1/3 + 1 3/8) miles
(7/3 + 11/8) miles
L. C. M = 24
(56 + 33) / 24
89 / 24
= 3 17/24 miles

take 10 and multiply it by 11 to get the length of the other side.
110
set the equation equal to that length
5x+10=110
-10 on both sides
5x=100
÷5 on both sides
x=20
