Answer:
7(6m - 4) = -364
multiply 7 for both variables in the parenthesis
42m - 28 = -364
move 28 to other side
42m= -336
divide 42 on both sides
m= -8
ANSWER
Find out the expression gives the percent of survey participants who chose swimming.
To proof
As given
75 girls at a summer camp were asked to complete a survey about their favorite outdoor activity.
27 girls chose swimming
32 girls chose hiking.
FORMULA

total girls = 75
girls chose swimming = 27
put in the formula

= 36%
36% of survey participants who chose swimming
Hence proved
To solve the expression, the steps are add 19 and multiply by 5
<h3>How to solve the expression</h3>
Given the equation;
-3 = -19 + d/5
First,
Collect like terms
-3+ 19 = d/5
Add the values on the left side
We have
16 = d/5
Cross multiply
16 × 5 = d
We then have
d = 80
Thus, to solve the expression, the steps are add 19 and multiply by 5

Answer:
Step-by-step explanation:
Since the ratio is 4x:4x:7x, if we add all those numbers up we get 15. Then we do 75/15 to get what x equals. So we get 5. So x equals 5. Following the rules of multiplication, you do 4(5):4(5):7(5), and simplifying that further, you get 20:20:35. If we add all those values up, we should get 75, and we do!
If you're wondering why I did 4x:4x:7x instead of 4:4:7, it's because a ratio is just a...well ratio? It's easier to visualize if you put a variable because the variable could be anything, and you would have to multiply all the given values to get the same proportions. In summery, I did it so it was easier to visualize
The variable X (percentage) over 100 and 23 over 80.
