NeX [460]

Answer:

p = -6

Step-by-step explanation:

1) Distribute 3 through the parenthesis {3p + 12 = p}

2) Subtract 12 from each side {3p = p - 12}

3) Subtract p from each side {2p = -12}

4) Divide each side by 2 {p = -6}

The set of all positive integers that are divisible by both 15 and 35 is infinite. What is the least positive integer in this se

solniwko [45]

Answer:

105

Step-by-step explanation:

A "set" is a group of numbers.

A "positive integer" is a whole number that's bigger than zero.

"divisible by both 15 and 35" means a number that 15 and 35 goes into (with no remainder)

"least" means smallest.

15 and 35 both go into 105.

Find the area of a circle with a circumference of 6.28 units.<br> units2

Nuetrik [128]

Answer:

$circumference = 2\pi r\\\\6.28 = 2\pi r\\\\r = \frac{6.28}{2\pi}$

$Area = \pi r^2 = \pi (\frac{6.28}{2\pi} )^{2} = \frac{6.28 \times6.28}{4\pi} = 3.14 square \ units$

Please solve this system of equations.<br> 5x-2y=9<br> 12x-8y=4

sp2606 [1]

Answer:

(4,11/2)

Step-by-step explanation:

5x-2y=9

12x-8y=4

A quick look will tell us that neither the x- nor the y- coefficient is the same in both equations, so combining the two by addition or subtraction. We can see that 2 is a multiple of 8, since 2 x 4 = 8. We should multiply the first equation by 4.

4(5x-2y=9)

Now we need to decide if we should add or subtract the equations.

20x-8y=36

12x-8y=4

Since we need to have a -8 and a +8 to eliminate the variables, we should subtract them. Change all the signs of the second equation and combine.

20x-8y=36

-12x-8y=4

----------------

8x=32

Divide both sides by 8 to get the x-value:

$\frac{8x}{8} = \frac{32}{8}$

x=4

Now that we have our x-value, we need to plug in the y-value.

5x-2y=9

5(4)-2y=9

20-2y=9

-2y=-11

y=11/2

So our solution is (4,11/2)

Let's check our work.

5x-2y=9

5(4)-2(11/2)=9

20-22/2=9

20-11=9

9=9

12x-8y=4

12(4)-8(11/2)=4

48-88/2=4

48-44=4

4=4

Our solution is correct.
