Step-by-step explanation:
Let's solve your equation step-by-step.
−5(x+4)=70
Step 1: Simplify both sides of the equation.
−5(x+4)=70
(−5)(x)+(−5)(4)=70(Distribute)
−5x+−20=70
−5x−20=70
Step 2: Add 20 to both sides.
−5x−20+20=70+20
−5x=90
Step 3: Divide both sides by -5.
−5x
−5
=
90
−5
x=−18
This is a unit rate question. We can solve this in chronological order of steps:
Step 1: Write out the beginning for the first unit rate.
Faith completed 60 burpees in 5 minutes last week.
Step 2: Since 60 burpees were completed in 5 minutes, we can divide 60 by 5 to find how many burpees were completed in 1 minute.
60 divided by 5 equals 12.
5 divided by 5 equals 1.
Our fraction for how many burpees Faith did in a minute last week is 12/1. This reduces to 12, meaning that Faith did 12 burpees last week.
Step 3: Find the unit rate for this week.
Faith completed 78 burpees in 6 minutes this week. Because of this, we can divide 78 by 6 to find how many burpees Faith completed this week.
78 divided by 6 equals 13.
6 divided by 6 equals 1.
Our final fraction for how many completed burpees Faith did this week is 13/1, which reduces to 13. Therefore, Faith completed 13 burpees per minute this week.
Your final answer: In terms of separate values, Faith completed 12 burpees per minute last week and 13 burpees per minute this week. If you need help, let me know and I will gladly assist you.

Answer:
Looks like you gave the answer already.
a = 8 and c = 5.5
Step-by-step explanation:
2a + 4c = 38.00 --> x3 --> 6a + 12c = 144
3a + 3c = 40.50 --> x2 --> 6a + 6c = 81
6c = 33
c = 5.5
a = 8
