<u>Part 1) </u>The sum of 4 and three times a number is 19

Let

x----------> the number

we know that

4+3x=19\\3x=19-4\\x=15/3\\x=5

therefore

<u>the answer part 1) is equal to</u>

The number is equal to 5

<u>Part 2)</u> The difference of twice a number and 7 is 9

Let

x----------> the number

we know that

2x-7=9\\2x=9+7\\x=16/2\\x=8

therefore

<u>the answer part 2) is equal to</u>

The number is equal to 8

<u>Part 3) </u>Ten less the quotient of a number and 3 is 6

Let

x----------> the number

we know that

\frac{x}{3} -10=6\\\\ \frac{x}{3} =16\\\\x=16*3\\\\x=48

therefore

<u>the answer part 3) is equal to</u>

The number is equal to 48

<u>Part 4)</u> Five times the sum of a number and 4 is -15

Let

x----------> the number

we know that

5(x+4)=-15\\5x+20=-15\\5x=-15-20\\x=-35/5\\x=-7

therefore

<u>the answer part 4) is equal to</u>

The number is equal to -7

4+3X=19, 3X=19-4=15, X=5

2Y-7=9, 2Y=9+7=16, Y=8

A/3-10=6, A/3=6+10=16, A=16*3=48

5(B+4)=-15, B+4=-15/5=-3, B=-3-4=-7

For the following figure what’s the value of x?
Leto [7]

Answer:

x = 8 in

y = 8sqrt(2) in

Step-by-step explanation:

x = 8

AC = BC

Because opposite angles are equal.

8² + 8² = hyp²

hyp² = 64 + 64 = 128

hyp = sqrt(128)

hyp = 8sqrt(2)

Where sqrt is the square root

Alex73 [517]

Answer:

-0.5x² + 20x + 100

Step-by-step explanation:

Given:

R = 25x - 0.5x²

C = 100 + 5x

P = R - C

Where,

P = profits

R = Revenue

C = Cost

which expression represents her profit in dollars?

P = R - C

R = 25x - 0.5x²

C = 100 + 5x

= 25x - 0.5x² -(-100 + 5x )

= 25x - 0.5x² + 100 - 5x

= -0.5x² + 20x + 100

The expression which represents her profit in dollars is -0.5x² + 20x + 100
