The large cup is best to buy. This is because it costs 11 cents per ounce for the medium cup and 11 cents for the large cup as well. You get almost double the amount for the same price with the large cup.

How to solve 1 2/3j=15
ivann1987 [24]

Answer:

j = 9

Step-by-step explanation:

The answer to the question above is solved below.

1 \frac{2}{3}j = 15

Convert the mixed numbers to improper fraction following the step: 1×3 = 3 +2 =5 / 3j = 5/3j

\frac{5}{3}j  = 15

Eliminate the fraction of the equation left hand side by multiplying both sides by 3

3 \times  \frac{5}{3}j = 3 \times 15

5j = 45

Divide both sides by 5

\frac{5j}{5}  =  \frac{45}{5}

j = 9

thus \: if \: 1  \frac{2}{3}j = 15. \: j = 9

A car used 16 gallons of gas to travel 240 miles . How many gallons would the car use to travel 180 miles
Nikitich [7]

Answer: 12 gallons

Step-by-step explanation:

The car uses 16 gallons to travel 240 miles. You need to calculate how many miles is in a gallon. So, divide 240 by 16 (you get 15). That is 15 miles per gallon. Next, you divide 180 by 15 to calculate how many gallons it would take you to travel 180 miles if there are 15 miles in a gallon.

Help geometry is so hardddd I’m failing
Umnica [9.8K]

Answer:

The answer is 3. (4,-2)

Step-by-step explanation:

Without doing the math to determine the length of the segment(s), plot the points on a graph. The only one that falls on the line is (4,-2). If we call (4,-2) C, then AC is approximately 12 units, CB is approximately 6 units. 12:6 = 2:1

HELP! 15 POINTS!
Brut [27]

It's pretty easy to go through the choices and none has a[2]=-36 and a[5]=2304.  Something's probably wrong with the way the question is typed, but I will answer what's written.

a_n = a + (n-1) d

a_2 = -36 = a + d

a_5 = 2304 = a + 4d

Subtracting,

2340 = 3d

d = 2340/3 = 780

a = -36 - d = -36 - 780 = -816

Answer: a[n] = -816 + 780(n-1)  which is none of the above

Check:

a_2 = -816 + 780= -36 \quad\checkmark

a_5 = -816 + 780(4) = 2304 \quad\checkmark
