Answer:
35 one-dollar bills
18 ten dollar bills
Step-by-step explanation:
We can solve this problem by using logic. First we have to understand that if all the 53 bill were $10 bills, then the combined monetary value would be...
53 x $10 = 530$
Now we start to replace the $10 bills with 1$ and each time we replace 1 bill, the combined monetary value will decrease by...
$10 - $1 = $9
We also know that we need to decrease the combined monetary value all the way to $215, which mean there has to be...
(530 - 215) / 9 = 35 one dollar bills.
And now since we know there are 35 one-dollar bills, that means there has to be...
53 - 35 = 18 ten dollar bills
Answer:
y=3x+4
Step-by-step explanation:
first you find the slope by doing change in y over change in x. The change in y is 9 because 7-(-2)=9. The change in x is 3 because 1-(-2)=3. Then you do 9/3 which is 3, which is your slope, or m.
So now you know y=3x+b, then you substitute one of the points in for x and y, and you get 7=3(1)+b, where b is your y-intercept. then you solve, and find that b=4.
Now you put it into slope intercept form, which is y=mx+b, where m=3 and b=4, so you are left with y=3x+4.
Leave a thanks if I am correct please.
Answer:
No solution
Step-by-step explanation:
4x+15 doesn't equal anything so it's impossible to solve.
Unless you forgot to add what it equals I can't solve it for you :(
