Answer:

The Least common multiple ( LCM) of 5 and 7 is 35

Step-by-step explanation:

We list the first few multiples of 5 and 7a and identify the common multiples .

The least among the common multiples is the LCM of 5 and 7.

LCM 5 and 7

Multiples of 5: 5,10,15,20,25,30,35,40,45

Multiples of 7: 7,14,21,28,35,42,49

<u>The</u><u> </u><u>Least</u><u> </u><u>common</u><u> </u><u>multiple</u><u> </u><u>of</u><u> </u><u>5</u><u> </u><u>and</u><u> </u><u>7</u><u> is</u><u> </u><u>3</u><u>5</u><u> </u><u>.</u>

<u>l</u><u> </u><u>hope</u><u> </u><u>it</u><u> </u><u>helps</u><u> </u><u>❤</u><u>❤</u>

What is the answer to the equation 13=1/6y + 2x
Eddi Din [679]
13=1/6y+2x
-1/6y  -1/6y
-1/6y+13=2x
         -13 -13
-1/6y=2x-13
   *-6   *-6
y=-12x-13

*I multiply it by -6 because -6 is the reciprocal of -1/6, and I can't divide -1/6, actually I can, but it just going to be more confusing that way, and the fastest way to get rid of the -1/6 when you solving this type of equation is multiply it by its reciprocal.

Find the slope between the two points: (3,-2) and (4,7)
cupoosta [38]
To find slope given two points, there is a formula you can use: (y2-y1)/(x2-x1). Y2 stands for the second y coordinate and y1 stands for the first y coordinate. The same logic applies to the x's. Let's assume that (3, -2) is x1, y1 and (4,7) is x2, y2. Let's plug them into the formula.

(7-(-2))/(4-3).
7-(-2)=9 for total y value.

4-3=1 for the x value.

Now we divide them.
9/1=9. 9=m. M is the variable commonly used for slope. Hope this helped!

Water weighs 62.4 pounds per cubic foot. How much does the water in a tank that measures 7 ft × 4 ft × 9 in, weigh?
andriy [413]

Answer:

  • <u>1,310 lb</u>

Explanation:

<u>1) Calculate the volume of the water in the tank.</u>

  • Area of the base of the tank: B = 7 ft × 4 ft = 28 ft²
  • Height of the tank: H = 9 in = 9 in × 1 ft / 12 in = 0.75 ft
  • Volume of the tank: V = area of the base × height = B × H = 28 ft² × 0.75 ft = 21 ft³.

<u>2) Calculate the weight of 21 ft³ of water.</u>

Since this is not a chemistry question but a math question, I will not use the fomula of density but set a proportion with one unknown:

  • 62.4 lb / 1 ft³ = x / 21 ft³

Solve for x:

  • x = 21 ft³ × 64 lb / ft³ = 1,310.4 lb.

So, rounding to the next integer, the water in the tank weighs 1,310 pounds, when it is full.

What is the equation of the line that passes through the points (−2, 1) and (1, 10)?
Viktor [21]

Answer:

3x - y = -7

Step-by-step explanation:

y = mx + b

m = deltay/deltax

m = (10 - 1)/[( 1 - (-2)]

m = 9/3 = 3

y = 3x + b

From (-2 | 1) we see that when x = -2, y = 1

Placing into the equation, in order to find b (y-intercept)

y = 3x + b

1 = 3(-2) + b

b = 7

y = 3x + 7 or 3x - y = -7
