One postive interger is 5 less than another. The product of the two intergerd id 24. What are the intergers?

Nesterboy [21]

Your function will be 24=X+(Y+5)

to solve you subtract 5 from each side giving you 19=X+Y now you divide the 19 by 2 so you figure out the base integers giving you 9.5

now you add 5 to one of your integers meaning 9.5+5=14.5

so your integers are 9.5 and 14.5

to check this you do 14.5-9.5 which equal 5 now you do 14.5+9.5 which equals 24

Solve each equation. Be sure to check your solution. 0.3a = 51

Aleksandr-060686 [28]

Answer:

a = 170

Step-by-step explanation:

0.3a = 51

a = 51 : 0.3

a = 51 : 3/10

a = 51 x 10/3

a = 510/3

a = 170

0.3x170 =

= 3/10x170

= 510/10

= 51

.The conversion of square feet to square yards can be represented by direct variation. Three square yards are equivalent to 27 s

Citrus2011 [14]

Answer:

The constant of variation is 1/9

The equation representing the direct variation is y/x= 1/9

Step-by-step explanation:

In direct variation, y/x=k denotes the equation, with k being the constant of variation. Here, y is the number of square yards and x is the number of square feet. Therefore, as we know that 27 square feet = 3 square yards, we can write one point (x₁, y₁) as (27 square feet, 3 square yards). Plugging x₁ and y₁ into our equation, we get

y/x = k

3 / 27 = k

(3/27) / (3/3) = 1/9* = k

Therefore, the constant of variation is 1/9

Next, as stated previously, y/x = k represents the equation of direct variation. Therefore, y / x = 1/9 as our equation

* because 3 is a factor of both 3 and 27, we can divide both the numerator and denominator by 3 to keep the fraction the same but also simplify it. One way to find the greatest common factor is to list the factors of each number and see the highest number that is a factor of both
