Answer:
(1,4)
x= 1
y= 4
(I checked on desmos and this is correct)
Step-by-step explanation:
I'm going to solve this by substitution
To do this we need to get a variable by istelf in any equation
We'll start with 18x-2y=10
We can add 2y and divide by 2 to get
y=9x-5
This is what y will equal for now and we can plug this in for y in the second equation
3x+16(9x-5)=67
This is rather easy to solve
147x-80=67
147x=147
this means that x=1
We can then use this value for x and plug it into any equation
let's just do the first one
18*1-2y=10
This is easy to solve as well and you should get
-2y=-8
y=4
this means that x=1
y=4
You can't simplify this further but can convert it to Trignometric form.
2(cos(pie/6)+ísin(pie/6))

?idk maybe it's supposed to be how long it's on the top but I know that not right sorry I dont get it
Answer:
it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
Step-by-step explanation:
1.5 pound = 1 1/2 pound equivalent to 3/2 pounds
3/5 of a 1.5-pound
= 3/5 × 3/2 pounds
= 9/10 lbs of goldfish eaten in 5/6 hours
how long, in hours, would it take her to finish a 5-lb box of goldfish?
Find the ratio
9/10 lbs of goldfish : 5/6 hours = 5lbs of goldfish : t hours
9/10 ÷ 5/6 = 5 / t
Solve for t
9/10 × 6/5 = 5 / t
54 / 50 = 5 / t
Cross multiply
54 × t = 50 × 5
54t = 250
Divide both sides by 54
t = 250 / 54
= 4 34/54
= 4 17/27 hours
Therefore, it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
