how do we find the value of a variable x in an equation?
Answer:
READ BELOW
Step-by-step explanation:
To solve for x, bring the variable to one side, and bring all the remaining values to the other side by applying arithmetic operations on both sides of the equation. Simplify the values to find the result.
The price of a gallon of apple cider is $7.00. The price
of eight 4.23 ounce juice boxes is $2.39.
Peter wants to have at least a gallon of either only cider
or only juice. Which product is the better deal?
Answer:
Apple Cider is the better deal.
Step-by-step explanation:
1 gallon is 128 ounces.
8 times 4.23 is 33.84. So each purchase is 33.84 ounces. If you multiply 33.84 ounces by 4 you get 135.36. (I did 4 because 3 would be too little to make a gallon).
After that you need to multiply 2.39 and 4. You need to do this because it will tell you the cost. That will come out to 9.56$.
So, that is why the apple cider is a better deal, because it is 7$ and the other would be 9.56$.
Hope this helps :-)

23 - 2x = 10 ??!! HELP PLSS
x = 6.5
Explanation:
[tex]\sf 23 - 2x = 10[/tex]
subtract 23 from both sides
[tex]\rightarrow \sf 23-2x-23=10-23[/tex]
simplify the following
[tex]\rightarrow \sf -2x=-13[/tex]
divide both sides by -2
[tex]\rightarrow \sf \dfrac{-2x}{-2}=\dfrac{-13}{-2}[/tex]
simplify
[tex]\rightarrow \sf x=\dfrac{13}{2}[/tex]
in decimals
[tex]\sf \rightarrow x = 6.5[/tex]
Recheck the following
[tex]\hookrightarrow \mathrm{23 - 2(6.5) = 10}[/tex]
[tex]\hookrightarrow \mathrm{23 -13 = 10}[/tex]
[tex]\hookrightarrow \mathrm{10 = 10}[/tex]
L.H.S = R.H.S thus. x = 6.5

Only 3/5 of the University students wanted to become math teachers if 3500 did not want to become math teachers how many university students were there?”
Answer:
8750
Explanation:
There are 5/5 math teachers in the university. 3/5 of them did not want to become math teachers which means 2/5 of the math teachers is equal to 3500.
3500=2/5
divide 3500 by 2 to get 1/5 of the math teachers.
3550/2=1750
1750 is 1/5 of the math teachers.
multiply 1750 by 5 to get 5/5 of the math teachers
1750*5= 8750

Answer choices 14x, 18x, 5x + 9 or 9x + 9
Answer:
5x+8 because 7x-2x=5x and you cant do anything with the 9 so it just stays as a hang on at the end.
Step-by-step explanation:
Answer:
7x + 9 - 2x
We need to combine like terms (meaning terms that have the same power and variables);
(7x - 2x) + (9)
5x + 9

Suppose that y varies inversely with x. Write an equation for the inverse variation.
y = 4 when x = 6
Answer:
y = 24/x
Step-by-step explanation:
[tex]\qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}} ~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\cfrac{\stackrel{\downarrow }{k}}{x}~\hfill } \\\\ \textit{\underline{x} varies inversely with }\underline{z^5} ~\hspace{5.5em} \stackrel{\textit{constant of variation}}{x=\cfrac{\stackrel{\downarrow }{k}}{z^5}~\hfill } \\\\[-0.35em] ~\dotfill[/tex]

Solve for x. Round to the nearest tenth, if necessary.
Answer: 20.4
Step-by-step explanation:
Solve for a:
9a-54=36
Answer:
a=10
Step-by-step explanation:
Step 1: Add 54 to both sides.
9a−54+54=36+54
9a=90
Step 2: Divide both sides by 9.
9a\9 =90\9
a=10
Answer:
a=10
Step-by-step explanation:
Add 54 to both sides. You get 9a=90. Divide both sides by 9 and you get a=10.
Evaluate m+(n/1.2). If m=4.204 and n= 4.5
Hey there!
m + (n/1.2)
= 4.204 + (4.5/1.2)
= 4.204/1+ (4.5/1.2)
= 4.204/1 + 4.5/1.2
= 4.204 + 3.75
= 7.954
Therefore, your answer is: 7.954

(x + 5)2 – 64 = 0
lesser x =
greater x =
Answer:
Step-by-step explanation:
( x + 5 )² - 64 = 0
( x + 5 )² = 64
x + 5 = ± √64
x + 5 = ± 8
(1). x + 5 = - 8
x = - 13 ( lesser )
(2). x + 5 = 8
x = 3 ( greater )
A school bus can safely carry as many as 76 students. If 19 students are already on the
bus, how many more can board the bus?
Answer:
57 students can still board
Step-by-step explanation:
If it carries 76 students total and 19 are already on, we must find the difference
This means we subtract
76 - 19 = 57
If Ill m, solve for x and y.
(7y - 20" (5x - 38)
(3x - 4)
Answer:
Solve for x = 17
Solve for y = 9
The value of x and y from the figure are 17 and 7 respectively
From the given diagram, we are told that I ll m, hence:
5x - 38 = 3x - 4 (alternate interior angle)Get the value of x
5x-3x = -4 + 38
2x = 34
x = 34/2
x = 17
Also from the triangle:
7y - 20 + 5x - 38 = 90
7y + 5x -58 = 90
7y + 5(17) = 90 + 58
7y + 85= 148
7y = 148 - 85
7y = 63
y = 63/7
y = 9
Hence the value of x and y from the figure are 17 and 7 respectively

A planting bed contains 0.75 tons of soil. A landscaper will apply fertilizer to the bed. The directions say to apply 1 ounce of fertilizer for every 100 pounds of soil.
How many ounces of fertilizer should the landscaper apply?
Answer:
15 ounces
Step-by-step explanation:
0.75 tons is equal to 0.75 * 2000, or 1500, pounds (1 ton is 2000 pounds). Let x represent the number of ounces of fertilizer that should be applied. Set up a proportion:
[tex] \ \frac{1}{100} = \frac{x}{1500} [/tex]
Solving this for x, we have x = 15. So the landscaper should apply 15 ounces of fertilizer.
