So 22.5 per barrel
so 22.5
x represents the number of 22.5 barrels
y represents the number of 35 barrels
so
x+y=1250
then find the total cost
1250 barrels
27.5 per so mutiply by 1250 and get 34375 total cost
22.5x+35y=34375
we have 2 senctances
x+y=1250
22.5x+35y=34375
elimination
mulitply first equation by -35 to clear y
-35x-35y=-43750
add to second equation
-35x-35y=-43750
<u>22.5x+35y=34375 +</u>
-12.5x+0y=-9375
-12.5x=-9375
multiply -1
12.5x=9375
divie both sides by 12.5
x=750
subsitute
x+y=1250
750+y=1250
subtract 750
y=500
750 barrells of the 22.5 oil should be included and
500 barrells of the 35 oil should be included
Answer:
it is 706.5 in sq
Step-by-step explanation:
Hello,
<u>We have :</u>
27 = 3³ = 3 × 3 × 3
³ = × ×
<u>So :</u>
The cube root of 27³ is :
3 × = 3
( because : (3)³ = 27³ )
<u>We have :</u>
8 = 2³ = 2 × 2 × 2
<u>So :</u>
The cube root of 8 is : 2
with 
and 
<u>We have :</u>
Have a nice day :)
Answer:
b and e.
Step-by-step explanation:
You will find this by solving each equation for 15b (get 15b by itself)
3 3/8. To figure this out, figure out how many times 8 goes into 27.
8 goes into 27 three times.
Now, multiply 8 and three together to figure out how many eights there are in 3.
3 = 24/8
There are still 3/8 remaining.
Your answer would be
3 3/8.
