Answer:

first number is 5

second number is 7

Step-by-step explanation:

let x and y represent the first and second number

5x - 2y = 11 ........ equation 1

3x - 2y = 11.......... equation 2

so by elimination, equation 1 minus equation 2

5x - 3x - 2y - 2y = 11 - 1

2x = 10

x = 5

therefore the first number is 5

put x = 5 into equation 1

5x - 2y = 11

5(5) - 2y = 11

25 - 2y = 11

-2y = 11 - 25

-2y = - 14

y = 7

therefore the second number is 7

hope it helps .

sasho [114]

Answer:

r

Step-by-step explanation:

<u>Function Modeling</u>

The problem gives us the following conditions: The bottom of Ignacio's desktop is 74.5 cm from the floor, and the top of his legs is 49.3 cm from the floor. We know the chair where he's sitting at has a knob that raises the legs 4.8 cm per clockwise rotation r. This means that the total distance the legs are raised for r rotations is 4.8r. The total distance of his legs from the floor is then:

49.3+4.8r

This distance cannot reach or exceed 74.5 cm, thus

49.3+4.8r

Solving for r

\displaystyle r

Or, equivalently

\boxed{r

Find the perimeter of a rhombus whose diagonals are
mojhsa [17]

Answer:

Rhombus Side = sqr root [(34 / 2)^2 + (30 / 2)^2]

Rhombus Side = sqr root [17^2 + 15^2]

Rhombus Side = sqr root [289 + 225}

Rhombus Side = sqr root [514]

Rhombus Side = 22.6715680975

Rhombus Perimeter = side * 4 = 90.68627239  cm

Larry earns $11.25/hour selling televisions. He also earns 4.5% commission on his sales. What is his
monitta

Answer:

C) $573.75

Step-by-step explanation:

We can come up with the equation of this Gross Weekly pay as:

P(t)=11.25t+0.045S

Where P is the amount Larry will get paid, t is the time worked and S is the amount of sales he generated that week.  This was derived from the fact that 11.25 is the slope and 0.045S is the y-intercept.  By plugging in those values we have:

P(35)=11.25(35)+0.045(4000)=573.75

C) $573.75
