If you subtract 25 from 12 you will get 13 cents. So you will get back 1 dime and 3 pennies.
I hope this helped you :)
I believe the answer is either 5 or -1.5
4n - 7 = 13
7 - 4n = 13
4(5) - 7 = 13
7 - 4(-1.5) = 13
4(5) - 7 = 13
Answer:
a=21
AB=23.9
BC=19.5
CD=(23.9)
AD=19.5
Step-by-step explanation:
Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:
a-1.5=19.5
add 1.5 to both sides
a=21
now substitute 21 in for a in each equation.
AB=CD so
AB=23.9
BC=AD so
BC=19.5
CD=(21)+2.9 so
CD=(23.9)
AD is given so
AD=19.5
