So first start out by writing an expression for the cost of the child and the adult separately.
Child:
6 + 1r ($6 + $1 per ride)
Adult:
10 + 1.5r ($10 + $1.50 per ride)
to find how much more the adult will spend, just do Adult Expression - Child Expression which will be:
10 + 1.5r - (6 + 1r) just simplify this
For Part B, use your equation from part A where r = 7
Answer:
20
Step-by-step explanation:
8x - 27 = 7x - 4
8x-7x = 24-4
x = 20
I hope im right!!
12=8 18=12 24=16 (find 2/3 of each one)
So 8, 12 and 16
Answer:
√14 and √42. hope this helps.
One example could be, 2 • (9x + 6y)
