We know that Marcus spent 10 hours on his homework this week so:
10 hours = 100%
Marcus is saying that he spent 110% more time doing his homework this week, in comparison to last week.
Then to see if he is correct we have to find 110% of 10 hours.
So if: 100% of 10 hours = 10 hours
And: 10% of 10 hours (equivalent to 600 minutes) = 1 hour (or 60 minutes)
Then we add the two: 10 hours + 1 hour
And we get: 11 hours
As a result, Marcus is correct; he did spend 110% more time on his homework this week.
Hope this helps! :D
Answer:
The answer is $2.50
Step-by-step explanation:
Its correct bruh
Answer:
Variant A
Step-by-step explanation:
1)y= - 3x+1
2)y+5= - 3(x-2)
y+5= - 3x+6
y= -3x+1
They are equal
Hey there! :D
Substitute y for 5x-1.
3x+2y=11
y=5x-1
3x+2(5x-1)=11
3x+10x-2=11
13x-2=11
13x=13
x=1
Now, plug that in to find y.
y=5x-1
y=5(1)-1
y=5-1
y=4
(1,4) <== the solution
I hope this helps!

Let x = amount invested in 2% CD and y = amount invested in 3% CD
x + y = 60000
0.02x + 0.03y = 1600
SOLVE THE 1st EQUATION FOR x AND SUBSTITUTE RESULT IN 2nd
0.02(60000 - y) + 0.03y = 1600
1200 - 0.02y + 0.03y = 1600
0.03y = 400
y = 13333.34
x = 46666.66
