Answer:
14w
Step-by-step explanation:
I don't know how to explain it any simpler than just to give you the answer which is 14w.
There is a more mathematical way of getting the 14w, but I'm guessing you won't like it. Use the distributive property. Put brackets around the given expression
7w + 7w = (7w + 7w)
On each side of the plus sign there is a common factor and that common factor is w
w(7 + 7) Now add the two 7s together.
14w
You could say to me, why didn't you take out the 7 to start with. You could
7 ( w + w) but w and w add up to 2w
7*2w
14 w
All you have to do for this is count every week the amount of money Duane and Mick earn. We'll start with $5 from Duane and $2 from Mick on the first week. The second week, only Mick gives $2, and so on. To earn $45, the two boys will have worked 10 weeks. I hope this helped! :)
Answer:
Step-by-step explanation:
Let x = $ invested in 8% account
y= $ invested in 10.5% account
x + y= 12000
0.08x + 0.105y = 1145
$4600 invested in the 8% account
and $7400 invested in the 10.5%
account
So you get 30.1 miles out of one gallon of gas, therefore you multiply the 30.1 by 7
30.1 x 7 = 210.7
this means that you would travel 210.7 miles on seven gallons of gas
6.7-2.3= 4.4 is the answer to the problem
