Answer:
x=4
Step-by-step explanation:
Cross multiply both sides to get 2(3x)=(x+20). Simplify to get 6x=x+20. Subtract x from both sides to get 5x=20, and divide both sides by 5 to get 4 as the value of x. The value of x will be your answer.
Answer:
A.) x = 4
Step-by-step explanation:
If [tex]\frac {(x+20)} {2} = 3x[/tex], then we plugin values:
[tex]\frac {(4+20)} {2} = 12[/tex] which is equal to 3(4).

Isabella noticed that when she doesn't study for a test, on average she makes a 45. Isabella also realizes that for every hour she studies, on average she scores an additional 7 points. Which of the following represents g, get average test score she studied for h hours?
a. 7-5h=g
b. 7+5h=g
c. 45+7h=g
d. 45-7h=g
Answers
Answer:
C. 45 + 7h = g
Step-by-step explanation:
This one would be correct because you have to add 7 points to the 45 points she would get on average without studying, without forgetting to multiply 7 by the number of hours that Isabella studied.
Example:
Let's say that Isabella studied for 3 hours. We could replace the h for the number of hours that she studied.
45 + 7(3) = g
Now you just have to solve the equation.
45 + 21 = g
Following the rules of PEMDAS, you would get rid of the parenthesis first by multiplying 7 times 3. Now you just have to add and you will have your answer for g.
g = 66

to express in decimal form , we have to join convert the mixed fraction into a improper fraction.
8 7/90 = d * w + n
= 90 * 8 + 7
= 720 + 7
= 727 / 90
now you have to make the denominator into a mutiple of 10
= 727 / 90 divided by 9

Choose 1 answer: Choose 1 answer:
Answers
Answer:
45mL hot cocoa is more chocolateyStep-by-step explanation:
When Arjun makes hot cocoa, if he add 20mL of chocolate syrup to 3ounces of water, let us know the equivalent chocolate in one ounces of water.
20mL = 3 ounces
x = 1 ounce
cross multiply
3x = 20
x = 20/3
x = 6.67 mL
This means he must have add 6.67mL of chocolate to 1 ounce of water.
Similarly, if 45mL is added to every 6 ounces
45mL = 6ounces
x = 1 ounce
cross multiply
6x = 45
x = 45/6
x = 7.5mL
This means he must have add 7.5mL of chocolate to 1 ounce of water.
The hot cocoa that is more chocolatey is the one with the highest amount of chocolate in 1 ounce. That is 45mL hot cocoa

Which of the choices below best describes the domain and range of this problem. Domain would be tickets sold and range would be amount of money he collected. Elijah has already sold $40 worth of tickets for a local raffle. He has 5 tickets left to sell at $5 per ticket.
Answers
Answer:
Step-by-step explanation:
Amount of ticket sold = $40
If one ticket is $5, we need to know the amount of ticket he sold that fetched Elijah $40
$5 = 1ticket
$40 = x tickets
Cross multiply
5x = 40
x = 40/5
x = 8tickets
If he has 5tickets left to sell at $5 per ticket, the total tickets the sold will be 8+3 = 13 tickets
The domain of the problem will be [1, 13]
For the range:
The amount of the remaining 5tickets will be (5×$5) = $25
Initial amount made = $40
Total amount he collected = $25+$40
= $65
The range if the problem will be [$5, $65]
