What is the missing reason in the proof

Area is Length x width.

Area = 4x * 5

Area = 20x

Replace A in the inequality:

Now you have 100 <= 20x <= 1,000

Now solve for x by dividing all 3 by 20:

5 <= x <=50

Check to see if they are viable:

4(5) x 5 = 20 x 5 = 100

4(50) x 5 = 200 x 5 = 1,000

Since the lowest number equals 100 and the largest number equals 1,000 all values of x would be viable. The answer is YES.

Answer:

  x = 3

Step-by-step explanation:

We don't know what equation you think is wrong.

The solution to the problem is ...

  x/2 +x/6 = 2

  x(1/2 +1/6) = 2 . . . . working using the given fractions

  x(3/6 +1/6) = 2

  x(4/6) = 2

  x(2/3) = 2

  x = (3/2)(2)

  x = 3

We can also work this by eliminating fractions first.

  x/2 +x/6 = 2

  3x +x = 12 . . . . multiply the equation by 6

Answer:

Cheryl's age = x = 7 years

Rita's age = y = 17 years

Step-by-step explanation:

Let

Cheryl's age = x

Rita's age = y

Two years ago, Rita was three times older than Cheryl

(y - 2) = 3(x - 2)

y - 2 = 3x - 6

y = 3x - 6 + 2

= 3x - 4

y = 3x - 4

In 3 years, Rita will be twice older than Cheryl

(y + 3) = 2(x + 3)

y + 3 = 2x + 6

y = 2x + 6 - 3

= 2x + 3

y = 2x + 3

Equate both equations

3x - 4 = 2x + 3

Collect like terms

3x - 2x = 3 + 4

x = 7 years

Substitute x = 7 into

y = 2x + 3

= 2(7) + 3

= 14 + 3

= 17

y = 17 years

Cheryl's age = x = 7 years

Rita's age = y = 17 years

Answer:

The answer should be 3/22.

Step-by-step explanation:

To multiply the fractions, multiply the numerators and denominators separately.

3 times 1 over 4 times 8,

Multiply straight across,

Answer should be 3/22

The 3/4 times 1/8 equals 3/32.

To calculate the product of fractions, you multiply the numerators together to get the numerator of the result, and multiply the denominators together to get the denominator of the result.

For 3/4 times 1/8:

Numerator: 3 × 1 = 3

Denominator: 4 × 8 = 32

Answer: See explanation

Step-by-step explanation:

Fron the question, we are informed that she bought 10 ounces of spicy popcorn for $2.50.

a. How much does popcorn cost per ounce?

1 ounce of popcorn = $2.50/10 = $0.25

b. How much popcorn can you buy per dollar?

Since 1 ounce of popcorn cost $0.25, $1 can buy popcorn worth:

= $1/$0.25

= 4 ounce of popcorn.

The relationship between the ounce of popcorn and the amount spent is an illustration of a linear function.

From the question, we have:

[tex]\mathbf{10oz - \$2.50}[/tex]

(a) The cost per ounce

To do this, we simply divide both sides by 10

[tex]\mathbf{Cost = \frac{\$2.50}{10oz}}[/tex]

[tex]\mathbf{Cost = \$0.25/oz}[/tex]

Hence, the cost per ounce is $0.25

(b) Popcorn for $1

To do this, we simply divide both sides by 2.5

[tex]\mathbf{Popcorn- \frac{10oz}{\$2.50}}[/tex]

[tex]\mathbf{Popcorn- 4oz/\$}[/tex]

Hence, the amount of popcorn for $1 is 4 ounces

(c) Represent as equations

In (a),  the cost per ounce is $0.25.

So, the equation is:

[tex]\mathbf{y = 0.25x}[/tex]

In (b),  the amount of popcorn for $1 is 4 ounces

So, the equation is:

[tex]\mathbf{x = 4y}[/tex]

Where: x represents the size of popcorn, and y represents the cost.

Answer:

see below

Step-by-step explanation:

Let f = number of friends

all but one friend got 6 pieces   and 1 friend got 2  for a total of 50 pieces

6(f-1) + 2 = 50

Subtract 2 from each side

6(f-1) +2-2 = 50-2

6(f-1) = 48

Divide by 6

6(f-1)/6 = 48/6

f-1 = 8

Add 1 to each side

f-1+1=8+1

f=9

Answer:

d = 10 sqrt(2)

Step-by-step explanation:

The distance formula is

d = sqrt( (y2-y1) ^2 + ( x2-x1)^2)

d = sqrt( (-1-9) ^2 + ( -4-6)^2)

d = sqrt( (-10) ^2 + ( -10)^2)

d = sqrt( 100+100)

d = sqrt(200)

d = sqrt( 200*2)

d = sqrt(100) sqrt(2)

d = 10 sqrt(2)

Answer:

Total pounds of spinach = 5 pounds

Pounds used for salad = 0.5 pounds

Step-by-step explanation:

Let

Total spinach = x

She used pan of spinach pie for a party = 3/5x

Remaining spinach = x - 3/5x

= 5x-3x/5

= 2/5x

She used 3/4 of the remaining spinach for a pan for her family

3/4 of 2/5x

= 3/4 × 2/5x

= 6/20x

= 3/10x

she used the rest to make a salad.

Salad = x - (3/5)x - (3/10)x

= (1 - 3/5 - 3/10)x

= (10-6-3/10)x

= 1/10x

If rose used 3 pounds of spinach to make the pan of spinach pie for the party how many pounds of spinach did rose use to make the saled

She used pan of spinach pie for a party = 3/5x

3/5x = 3 pounds

Divide both sides by 3/5

x = 3 ÷ 3/5

= 3 × 5/3

x = 5 pounds

Salad = 1/10x

= 1/10 * 5

= 5/10

= 0.5 pounds

Step-by-step explanation:

Answer:

Step-by-step explanation:

Factoring  x2-6x-30

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -30

Step-1 : Multiply the coefficient of the first term by the constant   1 • -30 = -30

Step-2 : Find two factors of  -30  whose sum equals the coefficient of the middle term, which is   -6 .

     -30    +    1    =    -29

     -15    +    2    =    -13

     -10    +    3    =    -7

     -6    +    5    =    -1

     -5    +    6    =    1

     -3    +    10    =    7

     -2    +    15    =    13

     -1    +    30    =    29
