Step-by-step explanation:

The third line of the solution is incorrect. It should be ...

  5x +2 = -5x +2

Then the one solution can be found:

  10x = 0 . . . . . . . . . add 5x-2 to both sides

A teacher divided 60 stickers among 3 students in a ratio of 2:3:5. How many stickers did each student receive?

Answers

Answer:

12:18:30

Step-by-step explanation:

I do RSM too, have a good day :)

The number of stickers did each student receive get is 12, 18 and 30 respectively.

Given that, a teacher divided 60 stickers among 3 students in a ratio of 2:3:5.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Here, 2+3+5=10

Number of stickers student 1 get

= 2/10 × 60

= 12

Number of stickers student 2 get

= 3/10 × 60

= 18

Number of stickers student 3 get

= 5/10 × 60

= 30

Therefore, the number of stickers did each student receive get is 12, 18 and 30 respectively.

examine the spinner at right. If the central angle of region A is 7 calculate the expected value of one spin.Round to the nearest hundredth..pls hurry

Answers

Answer:

The whole angle on a circle is equal to 360°.

This means that:

∠A + ∠B = 360°.

Here we know that ∠A = 7°

Then ∠B = 360° - 7° = 353°

Now, if the probability is evenly distributed for all the angles, then the probability that the spinner lands in A is equal to the quotient between the measure of the angle A, and the measure of the total circumference, this will be:

Pa = 7°/360° = 0.019

And the same for B:

Pb = 353°/360° = 0.981

Now, the expected value can be calculated as:

Ev = ∑xₙ*pₙ

Where xₙ is the event n, and pₙ is its probability.

Then:

x₁ = A = 100

p₁ = Pa = 0.019

x₂ = B = 2

p₂ = Pb = 0.981

The expected vale will be:

Ev = 100*0.019 + 2*0.981 = 3.862

Rounding to the nearest hundredth, the second digit after the decimal point, we have:

Ev = 3.86

(1) 51
(2) 64
(3) 72
(4) 102

will give brainliest asap!


Answers

It will be 3. 72 is your answer

Given the diagram given where lines n and p are parallel, and transversals r and s are perpendicular, the measure of angle 1 is: [tex]\mathbf{1) 51^{\circ}}[/tex]

The angle measure where two perpendicular lines intersect each other equals 90 degrees.

Therefore, the angle formed as shown in the figure attached, where transversals r and s meet = 90 degrees.

Since lines n and p are parallel lines, therefore:

[tex]m \angle 1 + 90 = 141[/tex] (alternate interior angles are equal)

Subtract 90 from each side

[tex]m \angle 1 = 141 - 90\\\\\mathbf{m \angle 1 = 51^{\circ}}[/tex]

Therefore, given the diagram given where lines n and p are parallel, and transversals r and s are perpendicular, the measure of angle 1 is: [tex]\mathbf{1) 51^{\circ}}[/tex]

x – 2y = 1
2x + 3y = -12

Answer:

x= -3

y= -2

From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.

X-2y=1
X=1+2y

2(1+2y)+3y=-12
2+4y+3y=-12
2+7y=-12

Janet can do a job in 3 hours, and Garry can do the same job in 2 hours. If Janet works for 1 hour before Garry comes to help, how long will it take them to do it together.

Answers

Answer:

48 minutes

Step-by-step explanation:

Given that:

Time taken by Janet = 3 hours

Janet's rate = 1/3 job / hour

Time taken by Garry = 2 hours

Garry's rate = 1/2

Rate of working together :

1/3 + 1/2 = (2 + 3) /6 = 5/6 job/hour

If Janet works for one hour before Garry joins ;

1/3 of the job has been done by Janet

1 - 1/3 = 2/3 of the job left

Hence to finish the job together, it will take :

Fraction of JOB left ÷ rate of working together

(2/3 ÷ 5/6)

= 2 /3 * 6/5

= 12 / 15

= 4 / 5 hours

(4/5) * 60

= 240/5

At a candy store, you can buy pre-filled bags of candy that weigh 2 1/4 pounds for $8. At this same rate, how much would a 4 pound
bag of candy cost?

Answers

Answer:

$14.22

Step-by-step explanation:

step one:

given data

we are told that 2 1/4( 2.25 pound) of candy cost $8

let us find the cost of 1 pound first

so

2.25 pound cost  #8

1 pound will cost x

cross multiply

x=8/2.25

x=$3.55 for one pound.

step two:

Hence  if 1 pound cost $3.55

4 pound will cost = 3.55*4= $14.22
