21 cars, 32 motorcycles.
create a system of equations using x for cars and y for motorcycles.
\left \{ {{x+y=53} \atop {4x+2y=148}} \right.
multiply the top equation by 2 to prepare for elimination method
\left \{ {{2x+2y=106} \atop {4x+2y=148}} \right.
subtract terms
\left \{ {{2x+2y=106} \atop {-4x-2y=-148}} \right.  = (-2x = -42)
divide both sides by negative 2 to solve for x
x =21
plug in x  into original equation to solve for y.
21 + y = 53
subtract both sides by 21
y=32

In the collection of beads, StartFraction 4 Over 20 EndFraction are blue. Which model shows the percent of beads that are blue?
jolli1 [7]

Option B model shows the percent of beads that are blue.

Solution:

Fraction of beads blue = \frac{4}{20}

To convert it into percent multiply the fraction by 100.

$\text {Percent of} \ \frac{4}{20}=\frac{4}{20}\times 100\%

                     $=\frac{4\times 100}{20} \%

Cancel the common factors, we get

                    = 20%

                    $=\frac{20}{100}

This means total number of boxes 100 and shaded in blue color 20.

Therefore option 2 represents \frac{20}{100}.

Hence option B model shows the percent of beads that are blue.
