In rectangle QRST, QS= 3x + 7 and RT= 5x - 3. Find the lengths or the diagonals of QRST

Marina CMI [18]

Answer:

The lengths of the diagonals is 22.

Step-by-step explanation: Since the shape is a rectangle, the diagonals are congruent, we can form the equation 3x+7=5x-3.

Solve for x; 2x=10-->x=5.

Plug 5 into one of the equations. 3(5)+7=22. 5(5)-3=22

Nonamiya [84]

Answer: 2.72 hours

Step-by-step explanation:

Let's call $t_1$ while it takes Wade to paint the room

Let's call $t_2$ while it takes Rhonda to paint the same room.

Then we know that:

$t_1 = 5\ hours\\t_2 = 6\ hours$ .

Let's call it t as it takes Rhonda and Wade to paint the same room working together.

Now we use the following formula to calculate t.

$\frac{1}{t}=\frac{1}{t_1}+\frac{1}{t_2}$

$\frac{1}{t}=\frac{1}{5}+\frac{1}{6}$

$\frac{1}{t}=\frac{11}{30}$

$t=\frac{30}{11}$

$t=2.72\ hours$

If they work together they will be able to paint the room in 2.72 hours

Ax-b=c solve for b<br> A- b= -ax-c<br> B- b=ax+c<br> C- b= -ax+c<br> D- b=ax-c

Alex

Ax - b = c....subtract ax from both sides
-b = -ax + c <==
or it could also have been b = ax - c (but that ones not there)
