Answer:

seventeen twenty ones

Step-by-step explanation:

2/3 - 4/7 + 15/21 = 17/21

Answer:

1. < 1 and < 3 are supplementary, meaning that the sum of these two angle measures is equal to 180 degrees. They are also alternate interior angles.

2. < 1  and < 2 are congruent, meaning that the measures of both of these angles are the same and are equal. They are also corresponding angles.

Answer:

2, 6, and 7

Yes, the smallest 2 sides sides add up to be larger than the longest side.

3, 3, and 3

Yes, any 2 sides sides add up to be larger than the other side. These sides would form an equilateral triangle.

5, 7, and 12

No, the smallest 2 sides sides do not add up to be larger than the longest side. 5 and 7 add up to be equal to 12 but not larger.

Step-by-step explanation:

If the 2 smallest sides of a triangle add up to be larger than the longest side, then the sides can create a triangle.

Answer:

x = 50°

Step-by-step explanation:

triangles add to 180 degrees

180 = 110 + 20 + x

180 = 130 + x

-130

x = 50°

Answer:

50°

Explanation

Since we know that a triangle is made up of [tex]180[/tex]° we can make an equation,

[tex]x+110+20=180[/tex]

solve it and we get that

[tex]x=50[/tex]°

Answer:

x=6

Step-by-step explanation:

2(3x-4)=28 is the formula.
Divide each side by 2 to get 3x-4=14

Subtract 4 on each side to get 3x=18
Then divide by 3 on each side to get the answer
x=6

The width of Saul's garden bed of rectangle form will be 6 feet.

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

The perimeter of the rectangle = 2( length + width).

As per the given,

Perimeter = 2(L + W) = 28 feet

The length of the garden bed will be 4 less than twice the width.

L = 2W - 4

2(2W - 4 + W) = 28

3W - 4 = 14

3W = 18

W = 6 feet

Hence "The width of Saul's garden bed of rectangle form will be 6 feet".

Answer: 75 + 0.05x = phone plan cost

Step-by-step explanation:

Define the following:

x = number of minutes used

Since you pay $75 upfront at the beginning of each month we have 75 in the equation.

We are given that 5 cents are charged for every minute of use. That's in addition to the $75 paid already. Remember to put 5 cents as 0.05.

⇒ 75 + 0.05x = phone plan cost

Answer:

The maximum height it reaches after its first bounce is 70 percent of 200 feet or 140 feet. After the second bounce, it reaches a height of 70 percent of 140 feet or 98 feet. In a similar fashion, the ball continues to rebound to a height that is 70 percent of the highest point of the previous bounce.

Step-by-step explanation:

dog = 35/85 = x/51

=> x = 35 x 51 / 85 = 7 x 51 / 17 = 21

Answer:

she is going to make 21 new dog cookies among 51 new cookies.

Step-by-step explanation:

Total cookies made → 35 + 14 + 36 = 85 cookies.

probability of making dog cookies: [tex]\frac{35}{85}[/tex]

so if new 51 cookies to be made,

among them dog cookies will be: [tex]\frac{35}{85}[/tex] * 51 = 21 dog cookies.

Not enough info.

Step-by-step explanation:

Parallelograms all have 2 equivalent side lengths. However, the rectangle is not the only parallelogram. A rectangle needs to have all right-angle corners (90 degrees).  You can see the small shape to the right of the drawing also has 2 equivalent side lengths but is not a rectangle.

Answer:

The answer is 10

Step-by-step explanation:

Answer:

to do this question, add width + height. 4/6 + 2/5 are not normally add-able. So to correct this, we find the most common factors. There is 1, 5, and 6 at highest. 5 and 6 share a high number multiple if you combine them. This multiple is 30. So now, keep, change, flip.

4x2 is 8.

6x5 is 30.

I would say the answer should be eight thirtieths.

Part A.

Both of them are partly correct. It is an absolute function, so for negative x's, y's are decreasing. For positive x's, y 's are increasing

They are nonlinear too

f(x)=|x|

because every y is positive even when the x values drop to negative. Therefore, and absolute function has to be used.

Answer:

Part A: 4x is the expression you would use. The variable "x" represents the number of deserts she would make.

Part B: 4x=24 is the equation you would use.

4x=24

Step 1 is to divide 4 on both sides. 4x/4 is x and 24/4 is 6. The new equation is x=6

Heather can make 6 deserts.

Step-by-step explanation:

Trust me!!! Have a nice day.

A) an expression with a variable that represents the amount of strawberries Heather needs for the desserts is,

⇒ 4x

B) There are 6 dessert she can make.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Heather is planning a dessert display.

And, She needs 4 ounces of strawberries for each dessert.

Let x represent number of dessert.

Hence, an expression with a variable that represents the amount of strawberries Heather needs for the desserts is,

⇒ 4x

And, If Heather has 24 ounces of strawberries

Then, Number of desserts is.

4x = 24

x = 6

Thus,

A) an expression with a variable that represents the amount of strawberries Heather needs for the desserts is,

⇒ 4x

B) There are 6 dessert she can make.

Step-by-step explanation:

Answer:

3/8

Step-by-step explanation:

We already know that 3/4 of the cookies are not chocolate chips, and half of those remaining cookies are peanut butter. We have to divide the fraction 3/4 in half.

We would actually write it as "3/4 * 1/2" because 1/2 is the reciprocal (fraction flipped upside-down) of 2 (which is what we would've divided it by to get halves). 3/4 * 1/2 = 3/8
