Answer: The ratio is wrong, it's 5 boys 6 girls
Explanation: To find this you would find the LCF (Least Common Factor) which would be 7, and divide both by 7, being 35/7 and 42/7, giving you the answers 5 and 6.
Answer:
ok that is correct because you start with 25 and then add 9 each week so 25+9w
Step-by-step explanation:
To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.
<h3>What is the average?</h3>
Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:
- 69 seconds.
- 58 seconds.
- 45 seconds.
- 120 seconds.
- 76 seconds.
The average time of my group of friends would be:
69 + 58 + 45 + 120 + 76 = 368
358 ÷ 73.6 seconds
The average of my group of friends would be 73.6 seconds.
According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.
Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

To find the x and y-intercept, we can write an equation in slope intercept form.
first, we need to find the slope
the formula for slope is
m= (y₂-y₁)/(x₂-x₁)
now just put any two points into the equation
m=(10-5)/(-9-(-15)
m=5/6
so now we can write the slope-intercept equation
y=5/6x + b
in a slope-intercept equation, b is equal to the y-intercept, so we can take one of our 3 pairs of points and put them into the equation to solve for b
15= 5/6(-3) +b
15=-2.5 + b
17.5 = b
so now we know the y-intercept is (0,17.5)
now we can write the equation as
y= 5/6x + 17.5
since the x intercept is when y=0, we can set y to 0 and then solve for x
0= 5/6x +17.5
-17.5 = 5/6x
-21 = x
by setting y to zero, we figured out that the x-intercept is (-21,0)
hope this helped!
a. 1.15
b. 6.20 divided by 4 = 1.55
c. 5 divided by 4 = 1.25
