Answer:
For every 5 female birds in the pet store, there are 3 male birds.
Step-by-step explanation:
Ratios are used to represent a proportion. In this case, we are comparing female and male birds. So, since female is 5 and male is 3, the ratio is 5:3
You do: 1/2 job/hr
Your friend does: 1/3 job/hr
Together: (1/2 + 1/3) job / hr
= (3/6 + 2/6) job/hr
= 5/6 job/hr .
Since you do 5/6 job/hr, the corresponding
inverse unit rate is
6/5 hr/job
= 1 and 1/5 hr/job
= 1.2 hours/job
= 1 hour 12 minutes per job.
Answer:
1.) 12x-10
2.)18x+10
Step-by-step explanation:
Eliminate x's by adding te 2 equations
add them
-2x+15y=24
<u>2x+9y=24 +</u>
0x+24y=48
24y=48
divide both sides by 24
y=2
sub back
2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3
x=3
y=2
(x,y)
(3,2)
Well 9x40 would be the solution, so what is 9x40? That will be your answer.
