A clown bought 5 bags of round balloons with 24 balloons in each bag. The clown also bought 3 bags of long balloons with 36 ball

dimaraw [331]

Answer:

247 blown up balloon left

Step-by-step explanation:

5 bags of round balloon with 24 balloon in each bag =

= 5 x 24 = 120 round balloons

3 bags of long balloon with 36 balloon in each bag =

= 3 x 36 = 108 long balloons

Part 1 Answer

120 round balloons - 108 long balloon = 12 balloons

therefore the clown bought 12 more round balloon than long balloon

Part 2

3 bags of heart-shaped balloons with 14 balloons in each bag =

= 3 x 14= 42 heart-shaped balloons

All the balloons were blown which equals

120 round balloons + 108 long balloons + 42 heart-shaped balloons =

= 270 balloons

23 balloons out of the 270 balloons burst which equals

270 blown balloon - 23 burst balloon = 247 blown-up balloons left

so,

247 blown-up balloons were left

Complete the equation of the line through<br> (-10, 3) and (-8, -8).

ad-work [718]

The answer is y = -5.5x - 52.

First, let's find the slope of the line.

m = Δy/Δx

m = -8 - 3 / -8 - (-10)
m = -11 / -8 + 10
m = -11/2
m = -5.5

Now, substitute the slope and one of the given points in the point slope equation.

<u>y - y₁ = m (x - x₁)</u>

y - 3 = -5.5 (x - (-10))
y - 3 = -5.5 (x + 10)
y - 3 = -5.5x - 55
y = -5.5x - 52

9x+2y-27z=-155 -11x-y+37z=208 19x+6y-52z=-304

Paladinen [302]

Answer:

(x,y,z)=( -2, -1 ,5)

Step-by-step explanation:

9x+2y-27z=-155 (1)

-11x-y+37z=208 (2)

19x+6y-52z=-304 (3)

(1) *3 ;(2) *6 ;(3)*1, you have

27x+6y-81z=-465 (1)

-66x-6y+222z=1248 (2)

19z+6y-52z=-304 (3)

(1) +(2), you have

-39x+141z= 783 (4)

(4) /3, you have

-13x +47z=261 (4)

(2) +(3), you have

-47x+170z=944 (5)

From ( 4) and (5), you have equations

-13x +47z=261 (4)

-47x+170z=944 (5)

(4)*(-47); (5)*13, you have

611x-2209z=-12,267 (4)

-611x+2210z=12,272 (5)

(4)+(5), you have

z=5

Replace z=5 in (4), you have

611x- 2209*5=-12,267

611x- 11,045 =-12,267

611x=-1222

x= -2

Replace x=-2, z=5 in (1) , you have

9*(-2) +2y -27*5=-155

-18+2y-135=-155

-18+2y=-20

2y=-2

y=-1

Result (x,y,z)=( -2, -1 ,5)

Here are the equations of 4 straight lines. Two of these lines are parallel what are the two parallel lines? A) y=2x+4. B) 2y=x+

Alchen [17]

Put ur equations in y = mx + b form and compare the slopes(m) and the y intercepts (b). Parallel lines will have the same slope but different y intercepts.

A) y = 2x + 4....slope is 2, y int is 4
B) 2y = x + 4
y = 1/2x + 2.....slope is 1/2 and y int is 2
C) 2x + 2y = 4
2y = -2x + 4
y = -x + 2.....slope is -1 and y int is 2
D) 2x - y = 4
-y = -2x + 4
y = 2x - 4....slope is 2 and y int is -4

ur parallel lines will have same slope and different y int.....so ur answer is A and D.
