Answer:

15x - 35 + 20y

Step-by-step explanation:

Simplify. Distribute 5 to all terms within the parenthesis:

5(3x - 7 + 4y) =

5 * 3x = 15x

5 * -7 = -35

5 * 4y = 20y

15x - 35 + 20y is your answer.

Multiply and do math

Answer:

holaaaaaaaa q tallllll

Answer: Choice C) There are 3000 milliliters in 3 liters

mL is the abbreviation for milliliters

L is the abbreviation for liters

Since 1000 mL = 1 L, we can multiply both sides by 3 to get 3000 mL = 3 L

Answer:

[tex](x^2-4y)(x^4+4x^2y+16y^2)[/tex]

Step-by-step explanation:

Factoring

We need to recall the following polynomial identity:

[tex](a^3-b^3)(a-b)(a^2+ab+b^2)[/tex]

The given expression is:

[tex]x^6- 64y^3[/tex]

To factor the above expression, we need to find a and b, knowing a^3 and b^3. a is the cubic root of a^3, and b is the cubic root of b^3:

[tex]a=\sqrt[3]{x^6}=x^2[/tex]

[tex]b=\sqrt[3]{64y^3}=4y[/tex]

Now we apply the identity:

[tex]x^6– 64y^3=(x^2-4y)[(x^2)^2+(x^2)*(4y)+(4y)^2][/tex]

Operating:

[tex]x^6– 64y^3=(x^2-4y)[x^4+4x^2y+16y^2][/tex]

The remaining factors cannot be factored in anymore. Thus the completely factored form is:

[tex]\boxed{(x^2-4y)(x^4+4x^2y+16y^2)}[/tex]

Answer:

136 degrees

Step-by-step explanation:

if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136

Answer:

Angle ABC is equal to 136 degrees.

Step-by-step explanation:

Since sides AB and BC are congruent (meaning they are equal to each other),  they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.

Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.

136 + 22 + 22 = 180, so this works!

Answer:

-To find the cost of one gallon of gas in Toronto, you have to multiply the cost of one liter of gasoline for 3.8 as you know that there are 3.8 liters in one gallon:

$0.91*3.8=$3.46

This means that a gallon of gas cost $3.46 in Toronto.

-$3.46-$2.29=$1.17

Considering that one gallon of gasoline cost $2.29 in Buffalo and $3.46 in Toronto, the cost is greater in Buffalo. The cost is greater by $1.17.

Step-by-step explanation:

Answer:

4^3

Step-by-step explanation:

When you are multiplying exponents with the same base (for this problem the base is 4) you add together the exponents. It is kinda hard to explain but that is just a rule you can use. So, 4^(5+(-2))=4^3

Answer:

The bridge can hold 1 ton

Step-by-step explanation:

Given that :

Model of bridge built is exactly 4 times smaller than actual bridge

Model bridge : actual bridge

1 : 4

From test,

Model bridge can hold 8000 ounces

Since actual bridge is 4 times the model bridge,;

Then, actual bridge should hold (8000 * 4) ounces = 32000 ounces

16 ounces = 1 pound

2000 pound = 1 ton

Hence,

32,000 ounces = (32000 / 16) pounds = 2000 pounds

Hence,

2000 pounds = 1 ton

Answer: 1 ton

Step-by-step explanation:

Answer:

Check explanation

Step-by-step explanation:

Here, we want to make a prove;

Mathematically , since D is the midpoint of CE

Then;

CE = CD + DE

Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE

I.e CD = DE

Hence, we can express CE as follows;

CE = DE + DE

CE = 2 DE

Divide both sides by 2

CE/2 = DE

Hence; DE = 1/2 CE

Answer:

7(x+5)-(2xy^2)

Step-by-step explanation:

"The product of 7" means multiplied by 7

"The sum of x and 5" implies addition

"minus the product of 2, x, and the square of y" means 2, x, and the square of y are all multiplied together subtracted from 7(x+5)

Hope this helps.

Answer:

[tex]\huge\boxed{x = 11,\ y = 3}}[/tex]

Step-by-step explanation:

In order to find the value of x and y in this, we have to note a couple of angle relationships.

We know that angles [tex]13x-19[/tex] and [tex]9x+25[/tex] are the same because they are corresponding angles. This means that when a line intersects two parallel lines, the angles formed are congruent to the second line.

This means both expressions for the line will be equal to each other:

[tex]13x-19 = 9x+25[/tex]

We can now solve for x.

Add 19 to both sides:

[tex]13x = 9x+44[/tex]

Subtract 9x from both sides:

[tex]4x=44[/tex]

Divide both sides by 4:

[tex]x=11[/tex]

Now that we know that x = 11, we can use another angle relationship to find y.

We know that [tex]13x-19[/tex] and [tex]17y+5[/tex] are supplementary angles. This means their angle measurements add up to 180°.

Since we know the value of x, we can find the measure of the angle [tex]13x-19[/tex].

[tex]13(11) -19\\\\143-19\\\\124[/tex]

So the [tex]13x-19[/tex] angle is equal to 124 degrees. Since this and [tex]17y+5[/tex] are supplementary, that means [tex]17y+5[/tex] must be equal to [tex]180-124=56[/tex] degrees.

[tex]17y+5=56[/tex]

Subtract 5 from both sides:

[tex]17y=51[/tex]

Divide both sides by 17:

[tex]y=3[/tex]

So, x = 11 and y = 3.

Hope this helped!

Answer:

Y=3

X=11

Step-by-step explanation:

9x + 25 is = to 13x - 19 so you would do exactly that.

9x + 25 = 13x -19

-9x -9x

25 = 4x -19

+19 +19

44 = 4x

4 4

11 = x

9*11+25= 124

And 124 is not equal to 17y+5 so the equation would be

124 + 17y +5 = 180

124 + 5 = 130

129 + 17y = 180

-129 -129

17y = 51

17 17

Y= 3

Answer:

BC is 24 units

Step-by-step explanation:

Given that: AB = 7 units

                  EC = 18 units

From a sketch for the question, we have a triangle ABC. Such that:

AC = AE + EC

But,

AE = AB = 7             (radius of the circle)

So that,

AC = 7 + 18

     = 25 units

Applying Pythagoras theorem to triangle ABC, we have:

[tex]/AC/^{2}[/tex] = [tex]/AB/^{2}[/tex] + [tex]/BC/^{2}[/tex]

[tex]25^{2}[/tex] = [tex]7^{2}[/tex] + [tex]/BC/^{2}[/tex]

[tex]/BC/^{2}[/tex] = 625 - 49

          = 576

BC = [tex]\sqrt{576}[/tex]

     = 24

Thus, BC is 24 units.

Answer:

1 banana = 0.25

Step-by-step explanation:

Find the proportion. Simply divide the cost from the amount of bananas given:

0.50/2  = 0.25

1.00/4 = 0.25

1.50/6 = 0.25

$0.25 is the cost per banana, and is your proportion.

~

Answer:

1 banana = + $0.25

2 bananas = + $0.50

Step-by-step explanation:

If it is increasing %0.50 for every 2 bananas then that also means it's increasing $0.25 for every 1 banana.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Anaconda:

Current length = 5.23metres

Growth rate = 1.27 metres per month

Python :

Current length = 4.76metres

Growth rate = 2.04metres per month

Number of months (m) in which both will be of the same length:

Anaconda = python

5.23 + 1.27m = 4.76 + 2.04m

Solve for m

5.23 - 4.76 = 2.04m - 1.27m

0.47 = 0.77m

0.47 / 0.77 = 0.77m / 0.77

0.610 = m

Answer:

Use the ABS function to find the absolute value of a number. The absolute value of a non-negative number (a positive number, or zero), is the same number. For example, the absolute value of 4 is 4.

Step-by-step explanation:

Explanation: The absolute value is defined as the distance from a number to 0 , and so it is always positive. So, the absolute value of −6 will be the distance from −6 to 0 on the number line, and it is 6
