Answer:
49 coins.
Step-by-step explanation:
It takes 10 dimes to equal a dollar, therefore fourty dimes equals four dollars.
Eight more dimes for the eighty cents, and one nickel for the 5 cents.
Since angle CDA + angle ABC = 180 then DC is Parallel to AB by transversal of parallel line theorem c-pattern for co-interior angles. to help visualize it draw it
F(-5)=3(-5)+4=-11
g(-2)=4(-2)^2+2=18
Answer:
x=-5, y=-1
Step-by-step explanation:
Substitute x=-4+y into -2x-5y=15. So we have
-2(-4+y)-5y=15
8-2y-5y=15
-7y=7
y=-1
And x is -4+y so x= -4+(-1)= -5.
