Well Step 1 is to do 56-26.
56
+70
=126 So we did that and it came out to 126.
Now we have to do 126-26.
126
-26
=100 in which 100 is your FINAL ANSWER!!!!
To do this you equate the two and use x for hours.
So your equation looks like this: 100+15x=75+17x. Now move like terms to get 25=2x. The job will be 12.5 hours long to cost the same.
Answer:
y = -3
Step-by-step explanation:
y= 1/4x and x = -12
Substitute x=12 into the first equation
y = 1/4(-12)
y = -3
Put this into ratio form:
20 baskets/ 4 minutes.
This means for every 4 minutes, you can make 20 baskets.
Now solve for 1 minute...how many baskets can you make in one minute.
You can solve this in many ways:
1. Cross Multiply:
20/4 = x/1...20×1= 20 ÷ 4= 5 baskets per minute
2. Simplify- (simpler way to solve)
20 baskets ÷ 4 minutes= 5 baskets in 1 minute
3. Critical Thinking:
how many times can 4 go into 20? 5 times. So there are:
5 baskets per minute
Answer: 4.64805 pounds of CO₂ was produced
Step-by-step explanation:
Given that;
wattage = 4694 watt = 4694 /1000 = 4.694 kW
time in use t = 10hrs
CO₂ was produced = ?
Total Energy produced = wattage × time = 4.694 kW × 10hrs = 46.95 kWh
we know that 1 kWh produces 0.99 pounds of CO₂
so
46.95 kWh will produce ⇒ 46.95 kWh × 0.99 = 4.64805 pounds of CO₂
Therefore 4.64805 pounds of CO₂ was produced
