3-3*6+2=? and explain how you came up with correct answer.

DedPeter [7]

Apply the PEMDAS rule to solve.

Multiplication   ⇒ 3*6 = 18

Rewrite    ⇒ 3-18 + 2

Straight across since we have opposite operations   ⇒ 3- 18 = -15

-15 + 2 = -13

Answer:   -13

The average temp at the south pole is -54°f. The average temp on the equator is 92°f. How much warmer is the average temp on the

podryga [215]

The answer to this question would just be the distance between -54 and 92. The easiest way to solve this would be with absolute value. If you have questions about what that means let me know.
|-54|+92=t
54+92=t
146=t
The average temp in the equator is 146 degrees Fahrenheit warmer than the average temperature in the south pole

Solve the system by graphing. (Enter your answers as a comma-separated list. If the system is inconsistent, enter INCONSISTENT.

timama [110]

Answer:

Part 1) The system has infinite solutions. Is a DEPENDENT system

Part 2) The solution of the system is the point (5,7)

Part 3) The solution of the system is the point (4,3)

Part 4) The number of investor that contributed with $4,000 was 33 and the number of investor that contributed with $8,000 was 27

Step-by-step explanation:

Part 1) we have

$x+y=7$ ------> equation A

$-x-y=-7$ ------> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The system has infinity solutions (both lines are identical)

see the attached figure

Is a DEPENDENT system

Part 2) we have

$x+y=12$ ------> equation A

$2x+3y=31$ ------> equation B

Solve the system by the elimination method

Multiply equation A by -2 both sides

$-2(x+y)=12(-2)$

$-2x-2y=-24$ ------> equation C

Adds equation B and C and solve for y

$2x+3y=31\\-2x-2y=-24\\---------\\3y-2y=31-24\\y=7$

Find the value of x

substitute the value of y in the equation A (or B or C) and solve for x

$x+(7)=12$

$x=5$

The solution is the point (5,7)

Part 3) we have

$3x+y=15$ ------> equation A

$x+2y=10$ ------> equation B

Solve the system by the elimination method

Multiply equation A by -2 both sides

$-2(3x+y)=15(-2)$

$-6x-2y=-30$ -----> equation C

Adds equation B and equation C

$x+2y=10\\-6x-2y=-30\\---------\\x-6x=10-30\\-5x=-20\\x=4$

Find the value of y

substitute the value of x in the equation A (or B or C) and solve for y

$3(4)+y=15$

$12+y=15$

$y=3$

therefore

The solution is the point (4,3)

Part 4) Formulate the situation as a system of two linear equations in two variables

Let

x ----> the number of investor that contributed with $4,000

y ----> the number of investor that contributed with $8,000

we have that

The system of equations is

$x+y=60$ ------> equation A

$4,000x+8,000y=348,000$ -----> equation B

Solve the system by elimination method

Multiply by -4,000 both sides equation A

$-4,000(x+y)=60(-4,000)$

$-4,000x-4,000y=-240,000$ -----> equation C

Adds equation B and equation C and solve for y

$4,000x+8,000y=348,000\\-4,000x-4,000y=-240,000\\-----------\\8,000y-4,000y=348,000-240,000\\4,000y=108,000\\y=27$

Find the value of x

Substitute the value of x in the equation A ( or equation B or equation C) and solve for x

$x+27=60$

$x=33$

The solution of the system is the point (33,27)

therefore

The number of investor that contributed with $4,000 was 33 and the number of investor that contributed with $8,000 was 27
