15:45 in simplest form is 1:3
the LCM of 15 and 45 is 15, and when you divide both by 15, you get 1:3
All you have to do is move the denominator on the other side, by multiplying.
a-10
------- = -9
20
multiply 20 x -9
= -180
then it becomes a-10=-180
+10 +10
a=-170
Answer:
a rise of 20 degrees
Step-by-step explanation:
since it started at -2 degrees, you have to add enough to get out of the negatives.
-2 + 2= 0, then 0+18 to get to the 18°
-2 + 20 = 18
You take your x, divide by 7. Take your 7x and add 6+4 and divide by 7. Then you have 112 degrees.
So 2×9=18 so she spend $18 on the pounds of food so 25-18=7 so the nuber of treats she can buy 7 treats for the animal shelter
