Answer:

18 boys

Step-by-step explanation:

we add 2 and 3 because they are equal parts:

2+3=5

Then we divide 45 by 5 because we want to find what 1 part equals"

45/5=9

We now do 9*2 to get an answer of:

9*2=18

hope this makes sense!

cluponka [151]

Answer:

$18.15

Step-by-step explanation:

Given that price before tax = $220

State sales tax rate = 4.6%

Dollar amount of state sales tax,

= 4.6% x $220

= 0.046 x 220

= $10.12

County sales tax rate = 3.65%

Dollar amount of state sales tax,

= 3.65% x $220

= 0.0365 x 220

= $8.03

Total amount of sales tax = $10.12 + $8.03 = $18.15

Find the equation of the line that passes through points (4,5) and (-1,6).
steposvetlana [31]
First find the slope using the formula m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}
Substitute the values in:
m= \frac{6-5}{-1-4}= -\frac{1}{5}
Point-slope form is y=m(x-x_{1})+y_{1}
Substitute (it doesn't matter which point you choose; I chose (4,5):
y=- \frac{1}{5} (x-4)+5=-\frac{1}{5}x+\frac{29}{5} 
Therefore, the answer is D. y=-\frac{1}{5}x+\frac{29}{5}

A person can do a job in 6 days. Another can do the same job in 4 days. If they work together, how long do they need to finish t
stepan [7]

Answer:

5 days

Step-by-step explanation:

This would have to do with average. So if one does it in 6 days and the other does it in 4 days, you would do the number between them. So 5 is between 4 and 6.

The more complicated way of thinking of it is like this...

add 6 and 4           6+4     that  would  =   10

Because we added two numbers, we have to divide by two.

10/2      which equals 5.

If it was numbers closer together like. 6 and 7 the middle numbeR would be 6.5 for example.

I hope this helped!!
