Answer:

Step-by-step explanation:

1 oz = 0.0625 lb

Ratio of the hiker an backpack in the first row = 152.25 lb : 14.5 lb

                                                                            = 21 : 2

Hiker's weight       Backpack weight                  Total weight (in lb)

1). 152 lb 4 oz                14 lb 8 oz                (152+14) lb (4+8) oz = 164lb 12oz

                                                                                                  = 16.75 lb

2). 107 lb 10 oz               10 lb 4 oz                (107+10) lb (10+4) oz = 117 lb 14 oz

                                                                                                        = 117.875 lb

3). 129 lb 15 oz           [tex]\frac{129.9375}{x}=\frac{21}{2}[/tex]                 (129+12) lb (15+6)oz = 141 lb 21 oz

                              x = 12.375 lb                                                      = 142.3125lb

                              x = 12 lb 6 oz

4). [tex]\frac{x}{8.75}=\frac{21}{2}[/tex]                   8 lb 12 oz                 (8 + 91) lb (14+12) oz = 99 lb 26 lb

   x = 91.875 lb                                                                                = 100.625 lb

  x = 91 lb 14 oz

5). [tex]\frac{x}{10}=\frac{21}{2}[/tex]                     10 lb                           (105 + 10) lb = 115 lb

    x = 105 lb                    

Answer:

Unit rate = 1 1/2 cups per serving

Step-by-step explanation:

1/2 serving has 3/4 cup

1 serving

3/4 * 1/2 = 3/4 * 2/1 = 6/4 = 6/4 / 2 = 3/2 = 1 1/2

Answer:

f(5) = 124

Step-by-step explanation:

Step 1: Define

f(x) = 22x + 14

f(5) = x = 5

Step 2: Substitute and evaluate

f(5) = 22(5) + 14

f(5) = 110 + 14

f(5) = 124

2. Next, you want to decide each side by 3 making it s = ⅓

Answer:

5t-5

Step-by-step explanation:

The minimum number of $0.10 stamps he needs to use is 1 stamp.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

let x represents the number of $0.44 cent stamps

and, y represents the number of $0.10 cent stamps

Ori uses all 3 of the $0.44 cent

=0.44x3

= 1.32

Then, 1.47-1.32= 0.15

We have at least 2 dimes for the equation

=0.44(3)+0.10(2)≥1.47

= 1.32+0.20≥1.47

= 1.52≥1.47

Then,  number of $0.10 stamps he needs to use

= 0.15/ 0.10

= 1.5

= 2 or 1 stamps

The value of x and y from the equation is 1/6 and 5/6 respectively

x = 1/6

y = 5/6

What is an Equation?

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 first equation be A

11x - 7y = -4   be equation (1)

Let the second equation be B

-14x - 2y = -4   be equation (2)

On simplifying , we get

Multiply equation (2) by 7 , we get

-98x - 14y = -28   be equation (3)

Multiply equation (1) by 2 , we get

22x - 14y = -8   be equation (4)

Subtract equation (4) from equation (3) , we get

-120x = -20

Divide by 120 on both sides , we get

x = 1/6

Now , substituting the value of x in equation (1) , we get

11x - 7y = -4  

11 ( 1/6 ) - 7y = -4

Adding 7y on both sides , we get

7y - 4 = 11/6

Adding 4 on both sides , we get

7y = 11/6 + 4

7y = 35/6

Multiply by 7 on both sides , we get

y = 5/6

Hence , the value of x is 1/6 and value of y is 5/6

Answer: x = -44

Step-by-step explanation:

1/2(x - 10) = [tex]\frac{3}{4}[/tex] (x+8)    Apply the distributive property

1/2x  - 5 = 3/4x + 6       Add 5 to both sides

         +5              +5

  1/2x = 3/4x + 11    Subtract 3/4x  from both sides

-3/4x       -3/4x

    -1/4x = 11       Divide both sides by -1/4

     x =   -44

x = 3,7

Answer:

2.5

Step-by-step explanation:

When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.

Because we don't know what x is, we have to work backwards.

The opposite of multiplying is dividing, so here we can do...

15/6  and that equals 2.5

To check you replace x with 2.5 like so,

6(2.5)= 15 and it is true!
