Answer:

\huge\boxed{\sf x =6,\ y = 42}

Step-by-step explanation:

Let the numbers be x and y

<h3>Given condition:</h3>

x + y = 48 --------(1)

y = 7x -------------(2)

Put Eq. (2) in (1)

x + 7x = 48

8x = 48

Divide 8 to both sides

x = 48/8

<h3>x = 6</h3>

Put x = 6 in Eq. (2)

y = 7 (6)

<h3>y = 42</h3>

\rule[225]{225}{2}

Assume a is the 1st number and b is the 2nd number, a + b = 48

<em>b = 7a</em> (the second number is seven times the first number​)

<em>a = a</em>

So, equation:<em> </em>a + 7a = 48

<em>a + 7a = 48</em>

<em>8a = 48</em>

a = 6

To find b = <em>7 (6)</em> = 42

Hope it helps!

Answer: The exponential function would be

Step-by-step explanation:

Since we have given that

We have points (0,15) and (2,24)

First we take when x= 0, y = 15.

So, our equation becomes,

and we take when x = 2 and y = 240

So, the exponential function would be

Select each equation which is equivalent to 60% of 25.
krek1111 [17]

The equation which is equivalent to 60% of 25 are x • 1.6 = 25, 0.6 • 25 = x and x/25=60//100

Percentages can be expressed as decimals or fractions.

Given the expression 60% of 25, this can b expressed as:

  • 60% of 25 = x

where x is the result of the expression.

  • 60/100 * 25 = x

Expressing 60% as a decimal will give;

0.6 of 25  = x

0.6 * 25 = x

From the expression 60/100 * 25 = x, this can also be written as:

25 = 100/60 x

25 = 10/6 x

25 = 1.6x

Hence the equation which is equivalent to 60% of 25 are x • 1.6 = 25, 0.6 • 25 = x and x/25=60//100
