Any time you have a subtraction and a negitive right next to eachother, it means to add. So, you would add 13 and 1 to get 14, then keep the denominator 19 to get 14/19.
Step-by-step explanation:
Answer:
y=1/2x+5/2
Step-by-step explanation:
expand the point-slope form and rearrange to y=mx+b
y-3=1/2(x-1)
y-3=1/2x-1/2
y=1/2x+5/2
Hey there! I'm happy to help!
Let's represent Ben's age with a B and Jeff's with a J in a few equations below.
B=J-9 (Ben is 9 years younger than Jeff)
B+10+J+10=67 (In 10 years, the sum of their ages will be 67)
We know that B is equal to J-9. So, in the second equation, we can replace B with J-9 to solve for J.
J-9+10+J+10=67
We combine like terms.
2J+11=67
We subtract 11 from both sides.
2J=56
We divide both sides by two.
J=28
And, we know that Ben is nine years younger than Jeff, so this means Ben is 19 years old.
Ben is 19 years old and Jeff is 28.
I hope that this helps! Have a wonderful day! :D
Answer:
the 7th
0.007805 or 59 / 756
Step-by-step explanation:
To determine the Friday that he needed more pounds, determine the number of pounds he needed per dog for each Friday.
to do this, divide the total pounds by the number of dogs
on the 14th
3/8 ÷ 35 =
3/8 x 1/35 = 3/280
on the 7th
1/2 ÷ 27 =
1/2 x 1/27 = 1/54
to determine which fraction is larger multiply each by 100 to determine its percent
3/280 x 100 = 1.071
1/54 x 100 = 1.852
1/54 is larger. Thus, more pounds was needed on Friday the 7th
the difference between these fractions should be determined
- 
=
= 59 / 756
