melomori [17]

Answer:

Chantal and Trisha will have both traveled 105 miles in 20 minutes.

Step-by-step explanation:

y is distance in miles, x is time in hours.

The two equations are:

y = \frac{20}{x} + 45

y = \frac{35}{x}

Set them equal to each other and solve for x:

\frac{35}{x} = \frac{20}{x} + 45

\frac{35}{x} - \frac{20}{x} = 45

\frac{35-20}{x} = 45

\frac{15}{x} = 45

x = \frac{15}{45} = \frac{1}{3} hours = 20 minutes

Plug that back into the equations to confirm this x gives the same y:

y = \frac{20}{1/3} + 45 = 105 miles

y = \frac{35}{1/3} = 105 miles

Create an equivalent expression by simplifying the expression below.
BabaBlast [244]

Answer:

see explanation

Step-by-step explanation:

Given

- \frac{1}{2} [ - \frac{3}{2} c + 6c + 1 ] - 3c

Distribute the square bracket by - \frac{1}{2}

= \frac{3}{4} c - 3c - \frac{1}{2} - 3c ← combine like terms

= \frac{3}{4} c - 6c - \frac{1}{2}

= \frac{3}{4} c - \frac{24}{4} c - \frac{1}{2}

= - \frac{21}{4} c - \frac{1}{2}
