Answer:
3x + 1/5y = 7
1/5y = 7 - 3x
y = 5 (7 - 3x)
y = 35 - 15x
Step-by-step explanation:
Answer:
6.39
Step-by-step explanation:
divide the total cost by the total amount of the item for the unit price:
38.34/6=6.39
You can solve this in two ways.
First way:
Let’s find out how many my friend makes in one minute.
12/5=2.4
He makes 2.4 in one minute. Let’s multiply that by 20 to find what he makes in 20 minutes.
2.4•20=48
My friend made 48 desserts.
Second way:
Let’s make a ratio.
12 desserts:5 minutes
X desserts: 20 minutes
Whatever you do to one side, you have to do to the other. Since you are multiplying the minutes by 4, you have to multiply the desserts by 4.
12•4=48
So, my friend made 48 desserts.
Tell me if this helps!!!
120% of 590=1.20*590=708.
For x% of a number y, the answer is x/100*y.
120 because 60 times two is 120 and six times two is twelve
