Answer: 60°
Step-by-step explanation:
- the two angles created by CD and EF are vertical angles so they are equal
- one angle is 30° so the other one is 30° and it splits an existing 90° angle so 90-30 = 60 so x is 60°
hope this helps :)
X = ski rentals, y = snowboarding rentals
x + y = 28......x = 28 - y
16x + 19y = 478
16(28 - y) + 19y = 478
448 - 16y + 19y = 478
-16y + 19y = 478 - 448
3y = 30
y = 30/3
y = 10
x + y = 28
x + 10 = 28
x = 28 - 10
x = 18
so 18 rented skis and 10 rented snowboards
Answer:
1
Step-by-step explanation:
So hmmm there are 5pennies in a nickel, and 10pennies in a dime and 25pennies in a quarter
now, in $6.10, there are 610 pennies
n = amount of nickels coins
d = amount of dime coins
q = amount of quarter coins
so... we know, there are 5*n or 5n pennies in the nickels, and 10*d or 10d pennies in the dimes and 25*q or 25q in the quarter coins, and we know their sum is 610 pennies total, thus
5n + 10d + 25q = 610
now, there are 4 more "n" then "d", so whatever "d" is, "n" is 4 more than that
n = d + 4
and twice as many "q" than "n", so, whatever "n" is, then
q = 2n
solve for "d", to see how many dimes are there
what about the nickels? well, n = d + 4
what about the quarters? well, q = 2d + 8
If you have e two linear functions and on a graph they are parallel that means they have the same slope with different y intercepts. If they are parallel and have the same y intercept then they would be the same graph. So no it’s not possible because there would not be two different graphs/functions; they would be exactly the same.
