The table below shows the price, in dollars, for the number of balloons indicated.

zysi [14]

Yes, the price is proportional because you can reduce their fractions:
16/4 = 4
24/6 = 4
36/9 = 4
56/14 = 4

!HELP I'M GOING TO FAIL! Find the missing horizontal side. Vertical side, and area of the playground.

Lyrx [107]

Answer:

Horizontal side: 7 ft

Vertical side: 12 ft

Area: 286 ft

Step-by-step explanation:

horizontal: 25 - 18 = 7

vertical: 10 + 2 = 12

area= (25x12) - (2x7) = 286

David wants to hang a mirror in his room. The mirror and frame must have an area of 8 square feet. The mirror is 2 feet wide and

hoa [83]

Answer:

4x^2+10x-2=0

Step-by-step explanation:

So the total area of mirror: 2*3 = 6 ft sq

8-6 = 2 ft sq is the area of the frame

x is the thickness of the frame

so we have (2*x)*2+(3*x)*2+x*x*4= 2

4x+6x+4x^2=2

-> 4x^2+10x-2=0

Suppose PR = 54, solve for QR 4x-1 3x-1 P R

Svet_ta [14]

Answer:

$QR = 23$

Step-by-step explanation:

P, A, and R are collinear.

PR = 54

$PQ = 4x - 1$

$QR = 3x - 1$

To solve for the numerical length of PR, let's generate an equation to find the value of x.

According to the segment addition postulate:

$PQ + QR = PR$

$(4x - 1) + (3x - 1) = 54$ (substitution)

Solve for x

$4x - 1 + 3x - 1 = 54$

Combine like terms

$4x + 3x - 1 - 1 = 54$

$7x - 2 = 54$

Add 2 to both sides

$7x - 2 + 2 = 54 + 2$

$7x = 56$

Divide both sides by 7

$\frac{7x}{7} = \frac{56}{7}$

$x = 8$

$QR = 3x - 1$

Plug in the value of x into the equation

$QR = 3(8) - 1 = 24 - 1$

$QR = 23$
