A jar contains 0.85 liter of strawberry juice and 0.50 liter of mango juice. Celina poured 0.15 liter of watermelon juice into the jar. She then drank 0.30 liter of the mixture. Part A: Write an expression to represent the total amount of juice left in the jar. (5 points)

Part B: Simplify the expression and identify which property is used in each step.

1.20

Step-by-step explanation:

0.85+0.50+0.15=1.50 -0.30=1.20

Step-by-step explanation:

PART A-To solve the question I must first add 0.85, 0.50 and 0.15 to a sum of 1.50, then I must subtract 0.30 from 1.50 to equal 1.20 which is how much juice is left.

PART B-I can simply the expression by doing this. 0.85 + 0.50 + 0.15 + ( -0.3 ) = 1.20. I used assositive property in adding because it does not matter what you add first.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
