Answer:
There are 8 girls
Step-by-step explanation:
We see that right now there are 6 more boys than girls and if there were 2 girls there would be 14 boys meaning there would be 12 more boys than girls if you continue in this pattern you would get-
7:1= 6 more boys 35:5=30 more boys
14:2= 12 more boys 42:6= 36 more boys
21:3=18 more boys 49:7= 42 more boys
28:4= 24 more boys 56:8= 48 more
This shows us that if there are 8 girls in group there are 56 boys meaning there are 48 more boys than girls if the group had 8 girls
An algebraic expression to represent the value of this car after M months is y=Mx+C.
We have given that the
The straight-line depreciation equation for a car is,
y = -2,680x + 26,800.
therefore after 4moths
y = -2,680(4) + 26,800.
y = -10720 + 26,800.
y=16080
<h3>
What is the slope?</h3>
The slope of a line is a measure of its steepness. Mathematically, the slope is calculated as rise over run (change in y divided by change in x)
b. For find after the 75 months replace x by 75 and slolve the given inequality.
Suppose that M represents the length of time in months when
the car still has value.
An algebraic expression to represent the value of this car after M months.
y=Mx+C.

Sum= addition
times= multiplication
at least= ≥
"At least" means the left side of the equation cannot be any less than 11. The left side will be at least/at minimum 11.
2x + 1 ≥ 11
subtract 1 from both sides
2x ≥ 10
divide both sides by 2
x ≥ 5
ANSWER: x ≥ 5; x is greater than or equal to (or "at least") 5
Hope this helps! :)
