Answer:

Ashley=13 messages

Frank=20 messages

Chang=2x+14=40 messages

Step-by-step explanation:

Number of texts sent by each person;

Ashley=x

Frank=x+7

Chang=2(x+7)=2x+14

Total number of text messages=Number sent by Ashley+Number sent by Frank+Number sent by Chang

where;

Total number of text messages=73

Replacing;

73= x+(x+7)+(2x+14)

x+x+2x+7+14=73

4x+21=73

4x=73-21

4x=52

x=52/4

x=13

Ashley=13 messages

Frank=x+7=13+7=20 messages

Chang=2x+14=(2×13)+14=40 messages

HELP ME PLEASE ASAP!!!!!: Stock worth $60 a share dropped in value by 20% on Monday. Then, it dropped again by $10 the next Tues
vredina [299]

Answer:

$58.9

Step-by-step explanation:

In this question, we're going to go step by step to get the final price of the share.

We know that the stock started off as $60 per share, so that would be our starting value.

The stock dropped by 20%, so let's calculate the drop in price.

60 • 0.20 = 12

60 - 12 = 48

On Monday, the value of the stock was $48

On Tuesday, the stock dropped by $10, so calculate that drop as well

48 - 10 = 38

On Tuesday, the stock value is at $38

The stock increased by 55%, so we need to calculate the increase.

38 • 1.55 = 58.9

This means that the final price of the share was $58.9

2. Two rectangular fields with identical shapes and areas are to be fenced side by side. The total area enclosed is 8mi^2 and th
CaHeK987 [17]

Step-by-step explanation:

Let length is x and breadth is y.

The formula for the area and the perimeter of a rectangle is given by :

A = xy

P = 2(x+y)

Here, A = 8 mi² and P = 16 miles

Putting all the values,

xy = 8

y=8/x ......(1)

2(x+y) = 16

x+y = 8 .....(2)

Put equation (2) in equation (1) as follows :

x+\dfrac{8}{x}=8\\\\x^2+8=8x\\\\x^2-8x+8=0

When we solve, we get :

x = 6.82 miles, 1.17 miles

Put the value of x in equation (1)

When x = 6.82 miles,

y = 8/6.82

y = 1.17 miles

When x = 1.17 miles,

y = 8/1.17

y = 6.82 miles

Hence, the dimension of the field is 6.82 miles and 1.17 miles.

Vesnalui [34]

Answer:

(80-10)/(2*2*12)

Step-by-step explanation:

80 - 10 = # of minutes

            = 70 minutes

In 70 minutes, you can make 2 batches.

In 2 batches, you can make 4 dozen muffins.

4 dozen = 4 x 12 = 48

Therefore the answer is 48 muffins

Equation: (80-10)/(2*2*12)
