A bag contains green marbles and blue marbles,

dexar [7]

There are 13 green marbles in the bag.

Step-by-step explanation:

Total marbles = 18

Let,

Green marbles = x

Blue marbles = y

According to given statement;

The number of green marbles is 2 less than 3 times the number of blue marbles.

x = 3y-2 Eqn 1

x+y=18 Eqn 2

Putting value of x from Eqn 1 in Eqn 2;

$(3y-2)+y=18\\3y-2+y=18\\4y=18+2\\4y=20$

Dividing both sides by 4

$\frac{4y}{4}=\frac{20}{4}\\y=5$

Putting y=5 in Eqn 1

$x=3(5)-2\\x=15-2\\x=13$

There are 13 green marbles in the bag.

Marely walked around 2 rectangular parks. One measures 54 feet by 38 feet and the other measures 32 feet by 22 feet.

galben [10]

Answer:

130 feet or 39.6m

Step-by-step explanation:

for Marely's first rectangular park, L=54 and B= 38

Total perimeter of distance walked in first rectangular park is 2(L+B), which is 2(54+38) =184 feet

For Marely's second rectangular park, L= 32 and B=22

Total perimeter of second distance 2(L+B), which is 2(32+22) = 108 feet

Total perimeter covered by Marely = (P1+P2) 184+108 = 292 feet

Marely's brother = 2(L+B)

2(48+33) = 162 feet

Hence, difference is 292-162 = 130 feet or 39.6m

What is -5x + 3y= 12 in slope intercept form?

babymother [125]

Answer:

y = (5/3)x + 4

Step-by-step explanation:

-5x + 3y = 12 (What you start with)

3y = 12 + 5x (Adding 5x to both sides)

y = (5/3)x + 4 (Dividing the equation by 3)
