Answer:
the answer to the whole equation is x=30.
Step-by-step explanation:
do 2/3(2) and -1/2(3)
4/6x and -3/6x
add the -3/6x to the other side
7/6x or 1 and 1/6x=5
times both by 6
x=30
1 divided by 5 is 0.2
0.2 <—- the 2 is in the tenths place so it is 20%
Your answer is B
Answer:
Number 7 is the last one which is 5x+6=8x-15. The answer to number 8 is x=7.
Step-by-step explanation:
5x+6=8x-15
-5x+15 -5x+15
--------------------
21 = 3x

3 3
x=7
Answer:
One fruit kabob and one smoothie
Two fruits kabobs and two smoothies
Three fruit kabobs and one smoothie
One fruit kabob and two smoothies
Explanation:
In this situation, the basic combination John can afford is simply to buy one fruit kabob and one smoothie ( $1.75 + $ 2.50 = $4.25) because he wants at least one unit of each item. Additionally, it is possible to add more units of each item to create new combinations or possibles, just make sure they do not total more than 9 dollars, which is the money John has. Here are some of the possible combinations:
Two fruit kabobs and two smoothies
Fruit kabobs: $1.75 x 2 = $3.5
Smoothies: $ 2.50 x 2 = $5
Total: $8.5
Three fruit kabobs and one smoothie
Fruit kabobs: $1.75 x 3 = $5.25
Smoothie: $2.50
Total: $7.75
One fruit kabob and two smoothies
Fruit kabob: $1.75
Smoothies: $2.50 x 2 = $5
Total: $6.75
Answer:
12 - 6 x (0 + 15) = 34
How I got my answer
First, how i got my answer was that I had to solve the equation first, ignoring the answer. I got 0 x 6 = 0, then I did 124 - 0 = 124, then I did 124 - 15 = 109, which clearly isn't 34. I figured that we have to put the parentheses around the zero because if we don't, we are going have to multiply something by zero, which always gets zero. After that, I decided that I should put the parentheses around either the 6, or the 15. I did both, and saw which one was correct. If we put it around the 6, we get, 124 - (6 x 0) + 15 = 124 - 0 - 15 = 124 - 15 = 109, which isn't 34. Then I checked 124 - 6 x (0 + 15) = 124 - 6 x 15 = 124 - 90 = 34, and we just got the answer.
P.S. Sorry if it was confusing, I didn't really know how to explain it
