Answer:

[tex]9m = 270[/tex]

[tex]m = \$30[/tex]

Joaquin needs to save $30 each week.

Step-by-step explanation:

Total money required for buying a surf board = $369

Money saved every week for first 11 weeks = $9

Total money saved in first 11 weeks = 11 [tex]\times[/tex] 9 = $99

Joaquin wants to buy the surf board in 9 more weeks.

To find:

Money to be saved each week for the next 9 weeks so that the surf board can be bought?

Solution:

Let the money to be saved each week for the next 9 months = $[tex]m[/tex]

Total money to be saved in the next 9 months = $9[tex]m[/tex]

Now, let us find the remaining amount of money to be saved by subtracting the total money saved from the cost of surf board. And then compare it with $9[tex]m[/tex].

[tex]369 - 99 = 9m\\\Rightarrow 9m = 270[/tex]

Solving the equation, we get:

[tex]m = \$30[/tex]

Therefore, Joaquin needs to save $30 each week.

Answer:

2.79 mi/hr    ( for the time they were actually moving)

Step-by-step explanation:

average speed = total distance / total time

                      = ( 10.4 + 8.6 mi) / ( ( 181 + 227 min )/60 min/hr) =2.79 mi/hr

Answer: 19, 35

Step-by-step explanation:

Two numbers: x and y.

x+y=54

x+16=y

x+x+16=54

2x+16=54

2x=38

x=19

19+y=54

y=35

19, 35

Answer:

x = 35

y = 19

Step-by-step explanation:

16 + x + y = 54

-16              -16

x + y = 38

          ÷2

x = 19

y = 19

The larger number is 16 more than the smaller number

x = 19 + 16 = 35

x = 35

y = 19

35 + 19 = 54

54 = 54

The longest side of the quadrilateral (in inches) is 29 inch.

Here,

The lengths of the four sides of a quadrilateral (in inches) are consecutive integers.

The perimeter is 110 inches.

We have to find the value of the longest side of the four side lengths.

What is Perimeter of quadrilateral?

The sum of all length of sides of a quadrilateral is called the Perimeter of quadrilateral.

Now,

The lengths of the four sides of a quadrilateral (in inches) are consecutive integers.

Let the length of quadrilateral are;

x, x + 1, x + 2 and x + 3

The longest length = x + 3

Since, The perimeter is 110 inches.

Hence,

x + (x + 1) + (x + 2) + (x + 3) = 110

x + x + 1 + x + 2 + x + 3 = 110

4x + 6 = 110

4x = 110 - 6

4x = 104

x = 26 inch

Hence, The longest length = x + 3 = 26 + 3 = 29 inch

Therefore, The longest side of the quadrilateral (in inches) is 29 inch.

Answer:

128 fluid ounces

Step-by-step explanation:

As per linear equation, there are 128 ounces of fluid in a gallon.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

Given relations for any fluid is:

1 cup = 8 ounces

1 pint = 2 cups

1 quart = 2pints

1 gallon = 4 quarts

Therefore,

1 gallon

=  4 quarts

= 4 (2) pints

= 8 pints

= 8(2) cups

= 16 cups

= 16(8) ounces

= 128 ounces

Therefore, for any particular fluid 128 ounces equal to 1 gallon.

15=x  5x=75

Step-by-step explanation:

90/6=15

6 is how many x's there are in total meaning that 1 x = 15

15*5=75 so one angle is 15 while the other is 75

75 + 15= 90

90+90=180 getting you the 180 degrees

Answer:

-14

Step-by-step explanation:

Find out how many times (-11) , (-1) and 17 appears.

(-11) is four times and (-1) is four time.

4 * (-1) + 4 * (-11) = 4 * (-1 - 11)

17 is appearing two times.

2*17

Now, the expression is,

4 * (-1 - 11) + 2 *17

4 * (-1 - 11) + 2 *17 = 4 *(-12) + 34

                            = - 48 + 34

                             = -14

Answer:

21 pounds

Step-by-step explanation:

Given that f varies inversely with l then the equation relating them is

f = [tex]\frac{k}{l}[/tex] ← k is the constant of variation

To find k use the condition f = 15 when l = 7, then

15 = [tex]\frac{k}{7}[/tex] ( multiply both sides by 7 )

105 = k

f = [tex]\frac{105}{l}[/tex] ← equation of variation

When l = 5 , then

f = [tex]\frac{105}{5}[/tex] = 21 pounds

Step-by-step explanation:

10+5(x−4)=35 Step 1: Simplify both sides of the equation. 10+5(x−4)=35

10+(5)(x)+(5)(−4)=35(Distribute)

10+5x+−20=35

(5x)+(10+−20)=35(Combine Like Terms)

Answer: 8% Error

Step-by-step explanation:

Lets go ahead and change the equation to a format that we're more familiar with.

Original:

50 -> 46

But what's easier is if we are working with 100's because of 100% right?

So lets do this.

100 -> 92

All I did was multiply both by 2 to get 100 to 92. Now it's easier to determine because of what we're looking at. 100-92 is 8% which also makes 50 to 46 an 8% error because of the symmetry between both equations. Enjoy!
