dybincka [34]

Answer:

8/9

Step-by-step explanation:

1 blue, 2 yellow, 7 red, 6 green, and 2 purple marbles = 18 marbles

The number that are not yellow = total - yellow

P( not yellow) = number that are not yellow / total

                       = (18-2) / 18

                       = 16/18

                       =8/9

Showing algebraic support, find the value of x.
Travka [436]

Answer:

x = 52.5

Step-by-step explanation:

The triangle on the left has 2 congruent sides, thus is isosceles

The base angles of an isosceles triangle are also congruent, thus

x = \frac{180-75}{2} = \frac{105}{2} = 52.5

.y=x+2<br> y = 2x - 5<br> How do we solve this
otez555 [7]

Answer:

X=7

Y=9

.y=x+2

y = 2x - 5

Use equivalents y=y so you get:

X+2=2x-5

X-2x=-5-2

-x=-7

X=7

Y=x+2=7+2=9

A photocopier increased the sides of a square in the ratio 4:5.
Svetach [21]

Answer:

The sides are increased by a percentage of 25%

Step-by-step explanation:

Let

x -----> the length side of the original square

y ----> the length side of the increased square

we have

\frac{x}{y} =\frac{4}{5}

y=\frac{5}{4}x

y=1.25x

the increase is calculated by subtracting x from y

so

y-x=1.25x-x=0.25x

Remember that

0.25=\frac{25}{100}=25\%

therefore

The sides are increased by a percentage of 25%
