Answer:
(-5, 3)
Step-by-step explanation:
Elimination seems like the best method to use here.
x+y=-2
x-y=-8
---------
2x=-10
Divide everything by two
x=-5
Now plug it back into one of the original equations,
-5+y=-2
Add 5 to everything
y=3
Answer:
The correct answer is C.
Step-by-step explanation:
There are 8 slots on Spinner B.
3 of those slots have squares.
Hence out of all the slots, 3/8 of them have squares.
Hope this helps:) Goodluck!
Answer:
c=10mm
Step-by-step explanation:
Using pythagoras theorem,
hypotenuse²=base²+altitude²
=√19²+9²
=19+81
=100
Hypotenuse²=100
Hypotenuse=√100
=10
Answer:
9) C: x=4, y=2rt3
10) A: XY/YZ
11) A: XY/XZ
Step-by-step explanation:
9 - that is a 30, 60, 90 triangle so the ratios will be a, root3a, 2a
10 - tan = opposite / adjacent
11 - cos = adjacent/hypotenuse
Answer:
675 gallons of syrup
96 cans
Step-by-step explanation:
Capacity of tank = 1,000 gallons
Danielle filled 65 5-gallon cans with syrup.
Gallons filled = 65 × 5 gallons
= 325 gallons of syrup
Gallons left in the tank = 1,000 - 325 gallons of syrup
= 675 gallons of syrup
3 12-packs Of regular cola = 3 × 12 packs = 36 packs
4 12- packs of diet cola = 4 × 12 packs = 48 packs
2 6-packs of orange soda = 2 × 6 packs = 12 packs
Total cans = 36 + 48 + 12
= 96 cans
