Answer:

Length is 22.5 ft

Width is 16.5 ft

Step-by-step explanation:

4L-w=73.5

4L=73.5+w

L=(73.5+w)/4

P=78

P=2L+2w

78=2[(73.5+w)/4]+2w

78=(73.5+w)/2+2w

78=(73.5+w+4w)/2

2•78=73.5+5w

156=73.5+5w

156-73.5=5w

82.5=5w

82.5/5=w

16.5=w

L=(73.5+w)/4

=(73.5+16.5)/4

=90/4

L=22.5

To solve -3 = -19 + d/5, what steps would you use?

Phantasy [73]

Answer:

1)Add 19

2)Multiply by 5

Step-by-step explanation:

$-3=-19+\frac{d}{5}$

Adding 19 to both sides.

$-3+19=-19+19+\frac{d}{5}\\\\16=\frac{d}{5}$

Multiplying 5 to both sides.

$16\times5=\frac{d}{5}\times 5\\80=d\\\\$

∴ $d=80$

One hose can fill a small swimming pool in 65 minutes. A larger hose can fill the pool in 60 minutes. How long will it take the

adelina 88 [10]

<h2><u>22 minutes 44 seconds</u></h2>

Step-by-step explanation:

1st horse time taken = 65 min/job; invert to get rate = 1/65 job/min

2nd horse time taken = 35 min/job ; invert to get rate = 1/35 job/min

Together Time taken = <em>n</em> min/job ; invert to get rate = 1/<em>n</em> job/min

------------------

Equation :-

Rate + Rate = together rate

1/65 + 1/35 = 1/n

-----------------------------

35<em>n</em> + 65<em>n</em> = 35*65

-----------------

100<em>n</em> = 2275

<em>n</em> = 22.75 minutes = <u>22 </u><u>minutes</u><u> 45 </u><u>seconds</u>
