3x+4=7 solve equation with work.
Answers
3+4=7
3x1=3
3+4 =6 so X =1
Answer:
X=1
Step-by-step explanation:
reverse multiplication -
7=4+3x
we know one value so we just isolate the 3x
7-4=3, meaning that 3x has to be equal to 3.
Then we just do 3/3=1 so therefore x=1
Also if you wanna check it then you can plug x=1 into the equation.

A company buys $4 phone cases and marks them up 250%. How much do they sell the phone cases for?
Answers
Answer:
$10
Step-by-step explanation:
Take the $4 that the company spends per phone case and multiply it by 2.5 which represents the 250% markup, and the result is $10
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The original price is:
100% = $4
New price:
250% = 250% x 4 =
The cost of the phone case after the 250% markup is $10.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
We have,
The original cost of the phone case = $4
Percentage markup = 250%
We can consider that the phone case's original price is 100%.
Now we need to find the price at a markup of 250%.
The cost of the phone case after the markup percentage.
= 250% of 4
= 250/100 x 4
= 5/2 x 4
= 5 x 2
= $10
Thus,
The cost of the phone case after the 250% markup is $10.

It took Helen 15 days to knit 100% of a quilt. Assuming she knit the same amount every day, how many days did it take her to knit 40% of the quilt?
Answers
Answer:
6
Step-by-step explanation:
100% -----> 15 days
40% ------> ? days
how to solve: (40 x 15) devided by 100
= (600) devided by 100
= 6
therefore, it took het 6 days to knit 40% of the quilt.
Answer:
Ok so 100% - 40% = 3/5 but if you do it in a decimal its 0.6 but if you subtrack 15 - 40% it kinda a impossible problem so lets try 40% - 15 = 73/5 and as a decimal 14.6...Uhm thats really all I can give you for your problem.
