Answer:

Step 1: Multiply the whole number by the denominator: 7 × 8 = 56.

Step 2: Add the product you got in Step 1 to the numerator: 56 + 1 = 57.

Step 3: Divide the sum from Step 2 by the denominator: 57 ÷ 8 = 7.125.

Step-by-step explanation:

Answer:

21

Step-by-step explanation:

Let the three consecutive integers be;

    x , x + 1 and x + 2:

The sum of squares of the two smaller numbers:

  The two smaller numbers are x and x+ 1

Sum of their squares:

           x² + (x+1)²;

        x² + x² + 2x + 1 = 2x² + 2x + 1

It is 45 more than the square of the larger number:

    Larger number = x + 2

        (x+2)² = x² + 4x + 4

 45 more;

        x² + 4x + 4 + 45  = x² + 4x + 49

Both are equal:

 2x² + 2x + 1 =  x² + 4x + 49  

  2x² - x² + 2x - 4x + 1 - 49 = 0

      x² - 2x - 48 = 0

      x² - 6x + 8x - 48 = 0

      x(x - 6) + 8(x - 6) = 0

      (x + 8)(x-6) = 0

      x + 8 = 0 or x - 6 = 0

      x  = -8 or x = 6

We choose x = 6 because it makes the solution true as a positive integer

  Sum of the three numbers:

     x + x + 1 + x + 2 = 6 + 6 + 1 + 6 + 2 = 21

6/8-5/8= 1/8

Answer:

1/8 of the jelly beans

Step-by-step explanation:

You need to create a common denominator between the two fractions. Since both 4 and 8 go into 8, that will be the common denominator. To get 4 to 8, you have to multiply by 2, so to even it out you multiply the numerator by 2(3x2) which equals 6. Now the first fraction is 6/8 and the second is still 5/8. If he ate 5/8 of 6/8 jelly beans, you need to subtract. 6/8 minus 5/8 is 1/8

Answer:

1.   487.5%

2.  43.45

Step-by-step explanation:

Remember the formula for a proportion: ((part)/(whole)) = ((percent)/(100))

1.

The part is given, 78, and the whole is given, 16.

Set up a porportion:

78/16 = percent/ 100

Simplify:

39/8 = percent /100

Cross products

39/8 = percent/100

8percent = 3900

Inverse operations

8percent = 3900

/8     /8

percent = 487.5

487.5%

2.

The percent is given, and the whole is given.

Set up a proportion:

part/55 = 79/100

Cross products

part/55 = 79/100

100part = 4345

Inverse operations

100part = 4345

/100    /100

part = 43.45

43.45

Answer:

No

Step-by-step explanation:

It isn't a positive linear association nor a negative linear association. If you were to connect those lines, it would not be a linear function of any kind of association.

Answer:

Yes

Step-by-step explanation:

Yes the answer is 6 x 2 - 36 ÷ 12 and it is correct. Although you could change this arithmetic expression by adding parenthesis to make it easier to read and know which operations come first, like so...

(6 x 2) - (36 ÷ 12)

This would make it easier to see that the 6x2 must be done first and then the 36/12 before doing the subtraction.

Answer:

the answer is a i believe

Step-by-step explanation:

The solution is Option A.

The total time it took to travel from the house to Gurnee Mills is given by the equation A = 2 hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total time to travel from the house to Gurnee Mills be A

Now , the equation will be

The time it took to travel to Gurnee Mills without waiting = 1 hour

The waiting time before travel = 1 hour

So , the total time to travel from the house to Gurnee Mills A = time it took to travel to Gurnee Mills without waiting + waiting time before travel

Substituting the values in the equation , we get

The total time to travel from the house to Gurnee Mills A = 1 + 1

On simplifying the equation , we get

The total time to travel from the house to Gurnee Mills A = 2 hours

Therefore , the value of A is 2 hours

Hence , the the total time is 2 hours

Answer:

(x + y)² = 35

Step-by-step explanation:

The expansion of

(x + y)² = x² + 2xy + y²

           = x² + y² + 2xy ← substitute given values

          = 25 + 2(5)

           = 25 + 10

           = 35

Answer:

35

Step-by-step explanation:

[tex]xy = 5 \\ \\ {x}^{2} + {y}^{2} = 25 \\ \\ \because \: {(x + y)}^{2} = {x}^{2} + {y}^{2} + 2xy\\ \\ \therefore {(x + y)}^{2} = 25 + 2 \times 5 \\ \\ \therefore {(x + y)}^{2} = 25 + 10 \\ \\ \huge \red{ \boxed{\therefore {(x + y)}^{2} = 35}}[/tex]
