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

One angle of an isosceles triangle measures 72°. Which other angles could be in that isosceles triangle? Choose all that apply.
54°
59°
36°
72°
Answer:
72 and 36
Step-by-step explanation:
Since it is an isosceles triangle we know that one of the angles will be 72 degrees as well. I added both of the 72s and got 144. A triangle has 180 degrees. Subtract 144 from 180 and you get 36.

Ellen bought new fish for her home aquarium. She bought 4 Turquoise Guppies and 3 Sunburst Tetra GLO Fish and spent a total of $41.73. Danielle bought 3 Turquoise Guppies and 5 Sunburst Tetra GLO Fish for a total of $56.02. How much was one Turquoise Guppy.
Answer: Ellen: 4t + 3s = 41.73
Danielle: 3t + 5s = 56.02
t = $3.69 each
Step-by-step explanation:
with 4t + 3s = 41.73 and 3t + 5s = 56.02
you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get
-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get
11/5t = 8.118 then divide 8.118 by 11/5 to get
t = 3.69

Hank is throwing a surprise party. The party costs $20 per person. Create an equation and graph to represent the relationship between the cost of the party and the number of friends attending.
Complete the following table:
Number of friends (f) 5 10 15 20
Cost of party (c) 100 200 300 400
Plots the points from the table onto the graph.
Answer: Answer with Step-by-step explanation:
Since we have given that
Cost of party per person = $20.
Let the number of friends be 'f'.
Let the cost of party be 'p'.
According to question, our equation becomes
p= 2f
So, if p = 100, then f = p/2 = 100/2 = 50 if f = 10, then, p = 2f = 2 • 10 = 20 If p = 300 then, f = 300/2 = 150, If f = 20, then, p = 2f = 2 • 20 = 40 So, Table as follows:
Number of friends cost of party
50 100
10 20
150 300
20 40

Rose has $426.00 in her checking account. 1⁄3 of her money will go toward bills. How
much of her money does she have left in her checking account? DO NOT PUT UNITS!!! Only put
numbers for your final answer.
Answer:
$284
Step-by-step explanation:
First, find 1/3 of 426 by multiplying 1/3*426
With your answer (142), subtract that from the total in your checking account.
426-142=284
This means, After withdrawing the amount she will use to pay bills, Her left over total will be 284 dollars.

A coefficient must have a multiplication sign after it. A True B False
Answer:
False
Step-by-step explanation:
Examples
The coefficient of 6x is 6. The coefficient of 19x is 19.
A coefficient is the number that is paired with a variable, but it does not need to have a multiplication sign after it in a equation.
The statement that a coefficient must have a multiplication sign after it is false
A coefficient is a number or expression that appears before a variable.
Take for instance:
The coefficient of x in 3x is 3The coefficient of y in 20y is 20The coefficient of z in 3xz is 3xIn the above samples, there is no multiplication sign after the coefficients.
Hence, the statement is false.

Cole has a rectangular garden with an area of 16.02 square meters. What is the width, in meters, of the garden?
Answer:
3.56m
Step-by-step explanation:Parameters given:
Area of the rectangular garden = 16.02m^2
Length of the rectangular garden = 4.5m
The Area of a rectangle can be calculated for using the formula below
Area (square meters) = length (meters) × width (meters)
Therefore, 16.02m^2 = 4.5m × width
Width = 16.02m^2 / 4.5m
Width = 3.56m
Therefore the width in meters of the garden is 3.56m
See the attachment below for an illustrative diagram
A = area
l = length
w = width

How would you classify the relationship between the two angles (2x+6 and 96) in the figure on the right?? Based on that classification, what is true about the measures of those two angles? Then find the value of x.
The photo is attached. :]
Answer:
They are vertical angles, all vertical angles are congruent, x=45.
Step-by-step explanation:
2x+6=96, subtract 6 from each side, => 2x=96, divide both sides by 2, => [tex]\frac{2x}{2}[/tex]=[tex]\frac{96}{2}[/tex]
x=45.
