A number is 6 times another number and their difference is 30. What are the numbers?

Alenkasestr [34]

Answer:

x=36

y=6

Step-by-step explanation:

Let the numbers be x and y

Condition 1

x=6y ----------(1)

Condition 2

x-y=30 ------------(2)

Putting 1 in 2

6y-y=30

5y=30

Dividing both sides by 5

y=6

Now

Putting y=6 in 1

We get

x=6(6)

x=36

The grocery store makes a 20% profit on baked goods. The profit for baked goods last month was $600. What was the total sales fo

torisob [31]

Let x = total sales of baked goods remember 20% = .20 as a decimal

so the equation would be .20x = $600

divide both sides by .20

.20x/.20 = $600/.20

x = $3000 the total sales of baked goods

CHECK: 20% times $3000 = .20 times $3000 = $600

The function f is defined by f(x) = 2x²-1.<br> Find f (2x).

umka21 [38]

Answer: $f(2x)=8x^2-1$

Step-by-step explanation:

All that is required here is to substitute x = 2x into the right side in the same way that is done for a numeric value.

$f(2x) = 2(2x)^2-1\\f(2x) = 2(4)x^2-1\\f(2x) = 8x^2-1\\$
