Hello,
(5x-2)+(2x+6)=67
==>7x+4=67
==>7x=67-4
==>7x=63
==>x=63/7
==>x=9
|AB|=5x-2=5*9-2=45-2=43 (miles)
The unit rate is 10:1 because unit rates are out of 1
You would find that by dividing 20 and 2 by the same number to get to one for this specific problem. 20 divided by two is ten and two divided by two is one. So that is your answer for part b. I can’t draw a graph however so sorry
Answer:
The first question is 9.
The second is 36.
The third is 8 1/2
Step-by-step explanation:
For the first one, there are 8 cubes plus the two halves, which equal 1 so 8 plus 1 equals 9.
The second one is 9 divided by a quarter which is 1/4, 9 divided by 1/4 equals 36.
For the third, length times witdth times height equals volume. So then (you don’t have to do it in order but) 2 times 1 times 4 1/4 equals 8 1/2.
Currently Josefin is 42. So let’s do doubled ages, since we’re adding 32 that means we have to be doubling 32. Which means Annette was 64, so 10 years ago!
Final answer: 10 years ago
Step-by-step explanation:
Total Price=SI+Priciple
SI=P×R×T
P=$1000
R=6%
T=3yrs
SI= 1000×0.06×3yrs
=$180
Total Price= Priciple + SI
=$1000 + $180
=$1180
