Answer:
<em>The answer is 200</em>
Step-by-step explanation:
<em>To solve the question given, let us recall the following,</em>
<em>Let r4=200 miles apart</em>
<em>r=50 mph combined speed
</em>
<em>Where </em>
<em>2f+10=50
</em>
<em>2f=40
</em>
<em>f=20
</em>
<em>f+10=30
</em>
<em>or we can express it in another way,</em>
<em>which is</em>
<em>f x4+(f+10)x 4=200
</em>
<em>f x4+f x4+40=200
</em>
<em>8f+40=200</em>
<em>Then</em>
<em>8f is =160
</em>
<em>f=20
</em>
<em>f+10=30
</em>
<em>Therefore,</em>
<em>4x 20+4 x 30=200
</em>
<em>80+120=200
</em>
<em>200=200</em>

Answer:
The three gallon container is the better buy. See below.
Step-by-step explanation:
8 pints
2 pints = 1 quart.

3 gallons = 12 quarts.
The cost of 1 quart = 54.48/12 = 4.54
Answer:
-9
Step-by-step explanation:
set y to 0
-2x + 1/2y = 18
-2x +1/2(0)=18
-2x / -2 = 18 /-2
x = -9
168÷21=8
The scale factor is 8
36×8=288
The building is 288 inches
