for the holiday season, brookfield zoo will be setting up for holiday magic, its annual lights festival. bob's job is to set up lights on various bushes and trees. on monday, bob used 44 strands of light to decorate 2 bushes and 3 trees. on tuesday, bob used 56 strands of lights to decorate 5 bushes and 3 trees. assuming all bushes and all trees are decorated with the same amount of lights, how many strands of light did bob use on each?
let x = strands of lights on bushes.
let y = strands of lights on trees.

a) create equation 1, which represents the amount of lights used on monday:
equation 1:

b) create equation 2, which represents the amount of lights used on tuesday:
equation 2:

c) solve for x. x =

d) use your x-value to solve for y. y =

e) bob used _blank_ strands of lights for each bush, and _blank_ strands of lights for each tree.
(i think the answer is either 22 strands of lights for each bush or 22 strands of lights for each tree but i don't know if 22 is right and if its right which one it goes too, tree or bush? )

(a)Equation representing amount of lights on Monday is 2 x  + 3 y = 44

(b)Equation representing amount of lights on Tuesday is 5 x  + 3 y = 56

(c) Bob uses 4 stands of light on Bushes

    and Bob uses 12 strands of lights on trees.

Step-by-step explanation:

Let x = strands of lights on bushes.

Let y = strands of lights on trees.

Bob used 44 strands of light to decorate 2 bushes and 3 trees on Monday.

So, the number of light on 2 bushes  = 2x

and  the number of light on 3 tress  = 3 y

⇒ 2 x  + 3 y = 44

Also, On Tuesday, Bob used 56 strands of lights to decorate 5 bushes and 3 trees.

So, the number of light on 5 bushes  = 5x

and  the number of light on 3 tress  = 3 y

⇒ 5 x  + 3 y = 56

Now, solving the system of equations:

2 x  + 3 y = 44

5 x  + 3 y = 56

Subtract equation (2) from (1), we get

2 x  + 3 y  - (5 x  + 3 y)  = 44   - 56

or, 2x - 5x = - 12

or, 3x  =  12 ⇒ x =  12/3  = 4    or x  = 4

Using x  = 4 in 2x + 3y = 44

2(4)  + 3y  =  44

or, 3y = 44- 8 = 36

or y = 36 /3 = 12 or y  = 12

So, the value of x  = 4, and y = 12

Hence, here Bob uses 4 stands of light on Bushes

and Bob uses 12 strands of lights on trees.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

answer: 193

explanation:

200-7 = 193
