Answer:
j=1/2k+5/2
Step-by-step explanation:
2j−k=5
Step 1: Add k to both sides.
2j−k+k=5+k
2j=k+5
Step 2: Divide both sides by 2.
2j/2=k+5/2
j=1/2k+5/2
That means that they did the same as last time they took the test
Answer:
6
Step-by-step explanation:
A painter mixes 2 1/2 pints (2.5 pints) of yellow paint with 4 pints of red paint to make a certain shade of orange paint. The ratio of yellow paint to red paint is 2.5:4. In order to find the pints of yellow paint needed to be mixed with 10 pints of red paint, we will use conversion fractions.
10 red pints × (2.5 yellow pints/ 4 red pints) ≈ 6 pints (we round off to 1 significant figure)
