1.29x = 69.99
x = 69.99/1.29 = 54.26
(1.29x + 1.80y)÷(x+y) = 1.603
(69.99 + 1.80y)÷(54.26+y) = 1.603
69.99 + 1.80y = 1.603y + 86.97
1.80y - 1.603y = 86.97 - 69.99
0.197y = 16.98
0.197y/0.197 = 16.98/0.197
y = 86.20 gallons of ultra

Let g represent the number of gallons of ultra.
.. 1.603 = (1.80g +69.99)/(g +69.99/1.29)
.. 1.603(g +69.99/1.29) = 1.80g +69.99
.. 1.603(1.29g +69.99) = 1.29(1.80g +69.99)
.. 69.99(1.603 -1.29) = 1.29g(1.80 -1.603)
.. g = 69.99*(1.603 -1.29)/(1.29*(1.80 -1.603))
.. g ≈ 86.203

Edhelper Gas must sell 86.203 gallons of ultra to make the average selling price 1.603.

If 1/4x - 1/4 = 2 then 2 + 1/4 = 1/4x.
so 3/4 = 1/4x
3/4 is equal to 1/1.33 (reduce by dividing both numerator and denominator by 3)
so 4 x ? = 1.33. 1.33 / 4 = 0.3325
so (if you're solving for x) I believe the answer is x = 0.3325

??????????????????????
never [62]

Answer:

I belive the answer would be the first one. 2^28 x 3^20 x 9^4

Step-by-step explanation:

This is becasue you need to multiply the power on the outside of the parenthesis, (4).     7 times itself 4 times is 28, 5 times itself 4 times is 20, and then use the 4 for the 9. Hope this helps!

Solve 7x- c= k for x. <br>A. X = 7(k+C) <br>B. x = 7(K-C) <br>C. X = k+c/7 <br>D. X= k-c/7​
antoniya [11.8K]

Answer:

C

Step-by-step explanation:

you add c to both side which will then make it 7x=k+c then you would divide 7 from both sides leaving you with x=k+c/7. Except 7 will be under the k and c.
