please help me brainliest for correct answer the sides of a triangle are as follows; (3x - 2), (-5x) and (8x + 7). what is the expression of the perimeter?

Answers

Answer 1

Answer:

Perimeter = 6x + 5.

Step-by-step explanation:

The perimeter is the sum of the three sides.

Perimeter = 3x - 2 + (-5x) + 8x + 7

= 3x - 2 - 5x + 8x + 7

= 3x - 5x + 8x - 2 + 7

= 6x + 5.

Answers

Answer:

15 ounces per box

Step-by-step explanation:

The rate StartFraction 165 ounces Over 11 boxes EndFraction describes the relationship between the number of boxes and the weight of the crackers in the boxes. What is the weight, in ounces, of one box?

Total weight of crackers in the boxes = 165 ounces

Total number of boxes = 11 boxes

What is the weight, in ounces, of one box?

Weight per box of crackers =

Total weight of crackers in the boxes / Total number of boxes

= 165 ounces / 11 boxes

= 15 ounces per box

The weight, in ounces, of one box is 15 ounces

Paula has a large ball of yarn that she is going to use to knit a scarf for the winter. Every square inch on the scarf requires a certain number of yards of yarn from the ball. A linear model of this situation contains the values (11 , 352.99) and (30 , 126.7), where x represents the number of square inches knitted on the scarf, and y represents the number of yards remaining on the ball of yarn. How many yards of yarn did Paula start with?

Answers

Answer:

She started with 484 yarns

Step-by-step explanation:

Given

[tex](x_1,y_1) = (11,352.99)[/tex]

[tex](x_2,y_2) = (30,126.7)[/tex]

Required

Number of yarns she started with

The interpretation of this question is to calculate the y intercept.

We strt by calculating the slope (m)

[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]

[tex]m = \frac{352.99 - 126.7}{11 - 30}[/tex]

[tex]m = \frac{226.29}{-19}[/tex]

[tex]m = -11.91[/tex]

Next, we calculate the linear equation as follows;

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex](x_1,y_1) = (11,352.99)[/tex]

[tex]m = -11.91[/tex]

[tex]y - 352.99 = -11.91(x - 11)[/tex]

[tex]y - 352.99 = -11.91x + 131.01[/tex]

Make y the subject

[tex]y= -11.91x + 131.01 + 352.99[/tex]

[tex]y= -11.91x +484[/tex]

A linear equation has the form

[tex]y=mx + b[/tex]

Where

[tex]b = y\ intercept[/tex]

By comparison.

[tex]b = 484[/tex]

Hence, she started with 484 yarns

Amadahy wants to buy a card and two gifts for her friend. Cards cost 3.49 each and gifts cost $10.63 each. Amadahy has a 20$ bill. Does she have enough to buy these items? If so, how much change will she receive? Will she receive? If not, how much more money does she need

Answers

Answer:

Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).

Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).

If you need only 1 c of milk, what is your best choice at the grocery store---- a quart container, a pint container, or a 1/2 gal container?

Answers

Step-by-step explanation:

Since 1 gallon = 4 quarts ⇒ (1/2) gallons = 2 quarts

1 gallon = 8 pints ⇒ (1/2) gallons = 4 pints

1 gallon = 16 cups ⇒ (1/2) gallons = 8 cups

Therefore from the given relation with gallons we can describe the relation between the cups, quarts and pints.

(1/2) Gallon > quarts > pints > cups

If we need 1 cup of milk then a pint container will be the best choice at a grocery store.

Answers

Answer:

Step-by-step explanation:

You are planning a thanksgiving fest for all your family and friends. You invite 224 people. You plan to have a piece of pie for each guest. You only have $191 left in your budget. How many of each type of pie should you hut

Let the number of pumpkin pies = p

The number of apple pies = a

Pumpkin pies have 6 pieces and cost $5. Apple pies have 8 pieces and cost $7.

Hence:

p + a = 224 people

p = 224 - a

$5 × p + $7 × a = $191

5p + 7a = 191..... Equation 1

Substitute 224 - a for p in Equation 1

5(224 - a) + 7a = 191

1120 - 5a + 7a = 191

- 5a + 7a = 191

How do you divide 2.16 by 3

Answers

Answer:

by moving the decimal in both numbers twice to the right and doing normal long division (the decimal in 3 is at the end) to get the answer of 0.72

Answer:

The answser is 0.72 because you divide 2.18 by 3

Step-by-step explanation:

for using bace ten blocks you have too move the decimal number 2 spaces to the right. 2.16-->216 You need 21 ten rods and 6 cubes. Why: I wouldn't do 2 hundred flats because 2 isn't divisible by 3. Put the ten rods into 3 equal group, then do the same with the cubes. You should end up with 7 in each group since 21 divided by 3 is 7. You should also end up with 2 cubes in each group. So in one group you have 72. Now move the decimal back to where it came from, 2 spaces to the left. Now you have 0.72.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph take two points (0,3) and (5,6)

Slope m=6-3/5-0=3/5

Now let us find y intercept

3=3/5(0)+b

b=3

So formula for C in terms of n is C=3/5n+3

Hence,  the formula for C in terms of n is C=3/5n+3

Which of the following graphs correctly graph y=4^x
(PICS BELOW!!!) (HURRY)

Answers

Answer:

Thus, the 2nd or lower graph represents the graph of  [tex]y\:=\:4^x[/tex].

The correct graph is also attached below.

Step-by-step explanation:

Given the function

[tex]y\:=\:4^x[/tex]

Let us determine the y-intercept by setting x=0, and then determining the corresponding y-value.

now substituting x = 0 in the function

[tex]y=\:4^0\:[/tex]

Apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]

[tex]y = 1[/tex]

Thus, the y-intercept is (0, 1)

Now, if we closely observe the 2nd graph or lower graph, the y-intercept of the lower graph is (0, 1)

Thus, the 2nd or lower graph represents the graph of  [tex]y\:=\:4^x[/tex].

The correct graph is also attached below.

Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse?

Answers

Answer: I need to find the additive inverse of the number being su tracked. That number is -9.6. The additive inverse of -9.6 is 9.6.

Step-by-step explanation:

Answer:

Additive inverse can be defined as adding a number with the opposite or the negative of that number to equal zero. The additive inverse of 1 is (-1), the additive inverse of 2 is (-2) and so on.

Example: 5 + (-5) = 0

In this example, (-5) is the additive inverse.

You can then take additive inverse one step when finding the additive inverse when subtracting rational numbers.

Example: 7 - 4 = 7 + (-4)

3 = 3

When finding the inverse, it is important to keep in mind that what you do to one side, you must do the opposite to another. In the example above, because you subtracted a positive four on one side, you are going to add a negative four to the other. This will make the equation equal on both sides.
