Answer:

50

Step-by-step explanation:

There are 50 candies in the bag.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

John ate 40% of the candies in a bag.

If John ate 20 candies.

let the total number of Candies be x.

So, 40% of x = 20

40/ 100 x = 20

x = 2000/ 40

x= 50

Hence, there are total 50 Cadies.

Answer:x = 3

because (34x - 2) and (32x + 4) are two opposite angles

=> 34x - 2 = 32x + 4

⇔ 34x - 32x = 4 + 2

⇔ 2x = 6

⇔ x = 3

Answer:

{x+y=36

0.1x+0.25y=5.4

Step-by-step explanation:

just took the test sorry for being late

The system of equation that is used to find how many dimes and quarters Victor has is :

x + y = 36

0.1x + 0.25y = 5.40

x = number of dimes

y = number of quarters

Therefore,

Total number of coins will be

1 dime = $0.1

1 quarters =$0.25

Therefore,

Total amount of dollars will be

combine the equations:

x + y = 36

0.1x + 0.25y = 5.40

Therefore, the system of equation that is used to find how many dimes and quarters Victor has is as follows:

x + y = 36

0.1x + 0.25y = 5.40

Answer:

  factors: (x +5) and (2x -1)

  zeros: -5 and 1/2

Step-by-step explanation:

The factorization can be aided by considering the factors of ac=2·(-5) that have a sum of b=9.

  -10 = -1×10 = -2×5

The sums of these factors are ...

  -1+10 = 9 (the pair we want), and -2+5 = 3

This means we can rewrite the function as ...

  g(x) = 2x² +10x -x -5

and factor by grouping.

  g(x) = (2x² +10x) -(x +5)

  g(x) = 2x(x +5) -1(x +5) = (2x -1)(x +5)

The factors of g(x) are (x +5) and (2x -1).

__

The zeros of the function are the values of x that make these factors be zero.

  x+5 = 0   ⇒   x = -5

  2x -1 = 0   ⇒   2x = 1   ⇒   x = 1/2

Answer:

The two middle sisters will each receive $250 and $350 respectively

Step-by-step explanation:

Let

The 4th sister = x

The 3rd sister = 100 + x

The second sister = 200 + x

The first sister = 300 + x

Total amount to share = $1,200

x + (x + 100) + (x + 200) + (x + 300) = 1,200

x + x + 100 + x + 200 + x + 300 = 1,200

4x + 600 = 1,200

4x = 1,200 - 600

4x = 600

Divide both sides by 4

x = 600/4

= 150

x = $150

There two middle sisters are:

The 3rd sister = 100 + x

= 100 + 150

= $250

The second sister = 200 + x

= 200 + 150

= $350

The two middle sisters will each receive $250 and $350 respectively

The 4th sister = x = $150

The first sister = 300 + x

= 300 + 150

= $450

If group of boy scouts are hiking the Appalachian Trail. They determine that they are traveling at a rate of 5 miles every 2 hours. It took 4hrs them to travel 10 miles.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

A group of boy scouts are hiking the Appalachian Trail.

They are traveling at a rate of 5 miles every 2 hours

We need to find how long will it take for them to travel 10 miles at the same rate.

Let x be the required time

5/2=10/x

Apply cross multiplication

5x=20

Divide both sides by 5

x=4

Hence it took for them 4 hours to travel 10 miles of distance

Answer: It should be division property of equality.

Answer:

Division Property of Equality

Step-by-step explanation:

To solve this problem Remus needs to isolate the variable, which means to get rid of the 7. Since the 7 is being multiplied the opposite operation needs to be used; the opposite of multiplication is division. So each side needs to be divided by 7, the division property of equality tells us that an equation can be divided by anything as long as it is done on both sides. So to solve use the division property of equality to do 7q/7=49/7, which equals q=7 when simplified.

Answer:

A) rectangular prism

Explanation:

The base is a rectangle, not a pentagon nor hexagon. So B and D are out.

The difference between a prism and a pyramid is the shape.

Prism just tends to be extensions of the base while the pyramid would have a pointy top, just like a pyramid.

There is no pointy top on the object, so it is a rectangular prism.
