You first have to divide 1,425/ 9, you’ll later then get the answer of 158 with a remainder of 3, the three can’t be evenly distributed and so THE ANSWER IS 3

the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80. What
Sladkaya [172]

Answer:

$166.42.

Step-by-step explanation:

We have been given that the price of the cell phone is expected to increase by 165% in September 2015. The current price of a cell phone is $62.80.

The price of cell phone in September 2015 will be $62.80 plus 165% of $62.80.

\text{The predicted cost of a cell phone in September 2015}=\$62.80+(\frac{165}{100}*\$62.80)

\text{The predicted cost of a cell phone in September 2015}=\$62.80+(1.65*\$62.80)

\text{The predicted cost of a cell phone in September 2015}=\$62.80+\$103.62

\text{The predicted cost of a cell phone in September 2015}=\$166.42

Therefore, the predicted cost of a cell phone in September 2015 will be $166.42.

A=1/2b(c+d) solve for c
TiliK225 [7]

Answer:

c = \frac{2A}{b} - d

Step-by-step explanation:

Multiply both sides by 2 to eliminate the fraction

2A = b(c + d) ← divide both sides by b

\frac{2A}{b} = c + d ← subtract d from both sides

\frac{2A}{b} - d = c

Complete the function table.
Nesterboy [21]

Step-by-step explanation:

with the y= 4x +1

they find the first column by replacing x in the function by 0

meaning if x= 0 then y=4(0) + 1 so y=1

for the second column if x =2 then y= 4(2) +1 so y= 9

for the 3rd one if x =4 then y = 4(4)+1 so y = 17
