7x+9=5x+3
2x+9=3
2x=-6
x=-3
Answer:
equation is 7x +9 = 5x +3x = -3Step-by-step explanation:
7x +9 = 5x +3
combine like terms
7x - 5x = 3 - 9
2x = -6
x = -6/2
x = -3
proof:
7x +9 = 5x +3
7(-3) +9 = 5(-3) +3

Find the x- and y-intercepts of the graph of the equation.
f(x) = 4x – 12
x-intercept
(x, y) =
y-intercept
(x, y) =
Answer:
x intercept is (3, 0). y intercept is (0, -12).
Step-by-step explanation:
x intercept is when y = 0. [f(x) = y] So 0 = 4x - 12. Solving for x gives you a value of 3. [12 = 4x; divide by 4]
y intercept is when x = 0. So y = 4(0) - 12. Solving for y gives you a value of -12. [y= 0 - 12; y = -12]

bracelet is $18. Need help what Is this solution
Answer:
the answer is $12
Step-by-step explanation:
to get the answer you would multiply 18 by 2/3 or you can divide by 3 then multiply what you get from dividing by 3 by 2.
version 1: 18(2/3) = ?
12
version 2: 18/3=?
6 you want to multiply by to because that is 1/3 of the original price

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets of information is given by b = 1500p where p represents the number of packets and b represents the number of bytes of information.
a. How many packets would be needed to transmit 30,000 bytes of information?
Answer:
20
Step-by-step explanation:
If you have 1,500 per package and you need to find how many you will need to get 30,000 all you have to do is divide 30,000 by 1,500 and you get 20 packages. So the final equation would be 30,000=1500(20)
HOPE THIS HELPS!
Answer:20 Packets
Step-by-step explanation:Each packet is worth 1500b so 30,000b/1500b gives you 20 packets

The value of m varies inversely as the square of n. When n = 3 m = 6.
What is the positive value of n when m = 13.5?
(I already know C. is wrong)
A. 18
B. 2
C. 9 XXXX
D. 4
Answer:
B.]2
Step-by-step explanation:
The required positive value of n is 2. Hence, option B is correct.
Important information:
m varies inversely as the square of n.Whem n = 3, then m = 6.Inverse proportion:It is given that m is inversely proportional to the square of n. So,
[tex]m\propto \dfrac{1}{n^2}[/tex]
[tex]m=\dfrac{k}{n^2}[/tex] ...(i)
Where, k is the constant of proportionality.
Substitute m = 6 and n = 3 in the above equation.
[tex]6=\dfrac{k}{3^2}[/tex]
[tex]6=\dfrac{k}{9}[/tex]
[tex]6\times 9=k[/tex]
[tex]54=k[/tex]
Substitute this value in (i).
[tex]m=\dfrac{54}{n^2}[/tex]
Substitute m = 13.5 in the above equation.
[tex]13.5=\dfrac{54}{n^2}[/tex]
[tex]n^2=\dfrac{54}{13.5}[/tex]
[tex]n=\pm \sqrt{4}[/tex]
[tex]n=\pm 2[/tex]
Therefore, the required positive value of n is 2. Hence, option B is correct.

Suppose 7 quesadillas is 49 dollars and 2 mexican burritos are 10 dollars. Find the price of 1 quesadilla and 10 mexican burritos. Explain how you set up this algebraic expression.
Answer:
17$
Step-by-step explanation:
quesadillas =x
burritos =y
7x =49 $
x=49 :7
x=7$cost a quesadillas
2 y =10$
y=10 :2
y=5$cost a burrito
x+10y
7 +2×5
17 $cost 1 quesadilla and 10 burritos
Answer:
1 quesadilla is 7 dollars and 10 burritos are 50 dollars
Explain:
49/7 is 7, so each quesadilla is 7 dollars. Also, 10/2 is 5 dollars, so each burrito is 5 dollars.

Mr. Nell is painting his coffee table. The micture that he adds to the paint is made of 5/6 cup
baking soda for every 5 tablespoons of water.
What is the rate in cups of baking soda per tablespoon of water?
Answer:
1/6 cups
Step-by-step explanation:
5/6 /5 = 5/6 divided by 5
= 5/6 x 1/5
= 1/6
so your answer is 1/6 cups of baking soda per tablespoon of water
yw ;)
The rate for cups of baking soda per tablespoon of water is 1/6.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The mixture that he adds to the paint is made of 5/6 cup baking soda for every 5 tablespoons of water.
Hence, The rate for cups of baking soda per tablespoon of water is,
⇒ 5/6 ÷ 5
⇒ 5/6 × 1/5
⇒ 1/6

option 2: [tex]\large \frac{10}{12}[/tex]
Step-by-step explanation:
when dividing fractions, you can actually multiply them together by the reciprocal of the second one. (reciprocal is just flipping the fraction)
so, [tex]\frac{2}{3}[/tex] ÷ [tex]\frac{4}{5}[/tex]
becomes [tex]\frac{2}{3} * \frac{5}{4}[/tex]
to multiply fractions together, just multiply the top and bottom.
