x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3
Answer:
the answer is D
Step-by-step explanation:
Plan 1 is the best choice because plan 2 would be an extra $120.00 more for the year.
No because Pam is reading 42 pages every hour so in 5 hours she would have only read 210 pages. Zack is reading 45 pages in an hour so he would finish just under 5 hours.
Answer:
<em>4,524 gallons</em>
Step-by-step explanation:
The volume of any cylinder is
π (radius)² (height) .
The pool's radius is 1/2 its diameter = 8 ft. So its volume is
π (8 ft)² (3 ft)
= π · (64 ft²) · (3 ft)
= π · 192 ft³
= 603.2 ft³ .
(603 ft³) · (7.5 gal / 1 ft³) = 4,524 gallons
Hope this helps :D
