7x+9=2x+39 i need all the steps
Answer:
Step-by-step explanation:
7x+9=2x+39
7x+9-9=2x+39-9
7x=2x+30
7x-2x=2x+30-2x
5x=30
5x/5=x
30/5=6
x=6
Answer:
X=6
Step-by-step explanation:
7x+9=2x+39
First, subtract 9 from both sides like this
7x+9 -9 =2x+39-9
equaling 7x=2x+30
Then, subtract 2 from both sides like this
7x - 2=2x -2+30
equaling 5x=30
Lastly you divide 5 from both sides like this
5x / 5 = 30 / 5
equaling x=6

Shari plans to sell pies at a festival for 3 days
-a table costs $40.00 a day to rent
-shari plans to sell each pie for $8.50
-each pie costs her $2.00
how much profit will shari earn if she sells 75 pies per day
Answer:
She will earn $517.5 in profit and will pay $120 for 3 days in rent of the table, and each pie will gain her $6.50 profit.
Explanation:
8.5*75= 637.5
63.5-120= 517.5
8.5-2=6.5

The measures of the angles of a triangle are shown in the figure below. Find the measure of the smallest angle.
(2x+18)°
55°
(4x+11)°
Answer:
(2x+18) degrees
Step-by-step explanation:
A triangle is a total of 180 degrees, so you would do:
(2x+18)+55+(4x+11)=180
(2x+4x)+(18+55+11)=180 <- take out parentheses and add like terms
6x+84=180 <- subtract 84 from both sides of the equation
6x=96 <- divide 6 from each side
x=16
Now that you know what x is you would plug it into each of the angles
Angle 1: 2x+18 --> 2(16)+18= 32+18= 50
Angle 2: 55
Angle 3: 4x+11 --> 4(16)+18= 64+18= 82
Then out of these three angles of the triangle, angle 1 (2x+18) would be the smallest.

#10 and 11
Questions are in the Picture
Answer:
Step-by-step explanation:
For problem 10:
1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)
2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)
3. 9/x=(9+6)/10 (Substitute the given values into this equation)
4. x=6 (Use algebra to solve for x)
For problem 11:
1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)
2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)
3. 14/(14+7)=18/(18+x) (Substitute given values)
4. x=9 (Solve for x)

One market sells a 3-kilogram bag of tortillas for 45 pesos, and the second market sells 2 kilograms of tortillas for 22 pesos.
Which unit price is lower? / Would I subtract 2 kilo from 22 pesos?
Answer:
The second market is cheaper
Step-by-step explanation:
For the first market:
If the 3Kg = 45 pesos
then 1Kg = 15 pesos because you divide it by 3
In the same way for the second market:
2Kg = 22pesos
so 1Kg is 11 pesos as you divide it by 2.
Therefore the second market is cheaper as the unit price is lower.

Which point is located at (8, 6)?
On a coordinate plane, point A is 8 spaces to the right and 6 spaces up. Point B is 8 spaces to the right and 8 spaces up. Point C is 6 spaces to the right and 8 spaces up. Point D is 6 spaces to the right and 6 spaces up.
A
B
C
D
Answer:
Point A is located at (8,6)
Step-by-step explanation:
As I said in the last answer I did for u, (8,6) basically means x is 8 and y is 6. If you see A, A is located on 8 for x and 6 for y. the others are incorrect such as B because B is on the 8 for x but the y is on 8. hope this helps '∆'
Answer:
A
Step-by-step explanation:
A is the answer because you look down at 8 and count up 6 times but dont count the 8 and your answer would be A ( A, 8 ) is on 6 .
Which of these systems of equations would be best solved using the subtraction method?
I. 2x−7y+3y = 4 −6x−4y = −52
II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52
Answer:
Step-by-step explanation:
1. x+2y=6 or x=6-2y
3x-2y=2
3(6-2y)-2y=2
18-6y-2y=2
18-8y=2
-8y=-18+2
-8y=-16
y=-16/-8
y=2 ans.
x+2*2=6
x+4=6
x=6-4=2 ans.
Proof:
3*2-2*2=2
6-4=2
2=2
I leave the rest for you to practice with.
3. 4x+y=7
2x+5y=-1
5. 3x+2y=-2
6x-y=6
Solve the system using the elimination method. Show all your steps.
7. -3x+3y=3
3x+y=9 add.
---------------------------------
4y=12
y=12/4
y=3 ans.
3x+3=9
3x=9-3
3x=6
x=6/3
x=2 ans.
Proof:
-3*2+3*3=3
-6+9=3
3=3
I'll leave the rest for practice.
9. -5x+12y=20
x-2y=-6

Hannah's hair was 18 inches long .Three years later it was 33 inches long. What was the percent increase,to the nearest hundredth, of Hannah's hair length?
Answer:
54%
Step-by-step explanation:
if you take 18 and divide it by 33 you would get 54
The 83.33 percent increase in Hannah's hair length.
What is the meaning of percentage?A percentage is a number or ratio expressed as a fraction of 100.
Hannah's hair was 18 inches long
After three years,
it was 33 inches long
[tex]Difference\ (increase\ in\ length) = 33-18=15\ inches[/tex]
[tex]percent\ increase = \dfrac{Increase}{Original\ Number}\times100=\dfrac{15}{18}\times100=83.3333\\\\percent\ increase = 83.33 (nearest\ hundredth)[/tex]
Hence 83.33 % increase in Hannah's hair length after three years.
