Answer:

x = (b + 5/a)

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and equals:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 5 to both sides of the equation:

ax - 5 (+5) = b (+5)

ax = b + 5

Next, divide a from both sides to isolate the variable, x:

(ax)/a = (b + 5)/a

x = (b + 5)/a

x = (b + 5/a) is your answer.

Mackenzie picked 20 strawberries, 5 blueberries, and 15 raspberries. What was the ratio of the number of strawberries to the tot

Korvikt [17]

Answer:

20:40

Step-by-step explanation:

Because part of the ratio is the total number of berries, we need to add up all of the berries.

20+15+5=40

The number of strawberries picked is 20, so the ratio is 20:40

PLEASE HELP!!!<br> Which expressions simplify to a rational answer? Select each correct answer.

Bond [772]

ANSWER

The first three expressions will simplify to a rational answer.

EXPLANATION

Let us simplify the expressions then we can see which of them are rational.

$7\sqrt{3} \times \sqrt{3}$

We multiply out the roots to get

$7\sqrt{3} \times \sqrt{3}=7 \times (\sqrt{3})^2$

This simplifies to

$7\sqrt{3} \times \sqrt{3}=7 \times 3$

$7\sqrt{3} \times \sqrt{3}=21$

This is a rational number hence the answer is rational.

$\sqrt{5} \times \sqrt{5}=(\sqrt{5})^2$

$\sqrt{5} \times \sqrt{5}=5$

This is also a rational solution.

$2\sqrt{9} \times \sqrt{4}=2\times3\times2$

$2\sqrt{9} \times \sqrt{4}=12$

This one too is a rational solution.

$\sqrt{3} \times \sqrt{16}=\sqrt{3}\times4$

$\sqrt{3} \times \sqrt{16}=4\sqrt{3}$

This is an irrational answer because √3 is an irrational number and multiplying a rational number, 4 by an irrational number results in an irrational number.

A sector of circle C shown below has a radius of 6 centimeters and a central angle that measures 80 degrees. Which expression be

777dan777 [17]

Answer:

The area of the sector is 8*pi cm² or 25.13272 cm².

Step-by-step explanation:

In order to calculate the area of a circular sector we can apply a rule of three in such a way that the circle's area, pi*r² cm², is related to 360º in such a way that "x" cm² is related to the angle of the sector. We have:

pi*r² cm² ---------> 360º

x cm² ------------> 80º

pi*r²/x = 360/80

360*x = 80*pi*r²

x = 80*pi*r²/360

x = 80*pi*(6)²/360

x = 80*pi*36/360

x = 8*pi cm²

The area of the sector is 8*pi cm² or 25.13272 cm².
