What is the variable in the algebraic expression - 9b + 11

Answer:

c is the correct option

Answer:

It would be d. 215,483 cm³

Step-by-step explanation:

Using the formula for volume of a cylinder which is πr²h and using 3.14 instead of π, we can put the numbers in.

3.14 (15²) (305) = 215,483

r = 15 because to get the radius you have to divide the diameter by 2.

Answer:

3:5 = 6: 10

Step-by-step explanation:

(3/5) × (2/2) = (3 × 2) / (5 × 2) = 6/10

Equivalent fractions can be written by multiplying or dividing both the numerator and the denominator by the same number. This is the reason why these fractions get reduced to the same number when they are simplified.

Let us understand the two ways in which we can make equivalent fractions:

Multiply the numerator and the denominator by the same number, or,

Divide the numerator and the denominator by the same number.

Hey there! 

3:5 

= 3 × 2 : 5 × 2

= 6 : 10

Therefore, your answer is: 6 : 10

Good luck on your assignment & enjoy your day!

Answer:

Step-by-step explanation:

1. Add: 2 1/4 + 3 2/3 = 5 11/12

2. Subtract: 6 11/12 - 5 11/12 = 1

So, 6 11/12 - (2 1/4 + 3 2/3) = 1

By Solving the given expression 6( 11/12) - (2 (1/4) + 3 (2/3)) the final answer will be 4(1/2).

By using the concept of arithmetic to solve a subtraction problem involving mixed numbers. We'll break down the steps for you, starting with the operation inside the parentheses, and then proceed to find the final result. Let's get started!

To solve 6(11/12) - (2 (1/4) + 3 (2/3)), we need to tackle the operation inside the parentheses first.

First, let's simplify the addition inside the parentheses:

2(1/4) + 3(2/3)

To add these mixed numbers, we need to find a common denominator. In this case, the least common multiple of 4 and 3 is 12. So, we'll convert both fractions to have a denominator of 12.

2(1/4) can be rewritten as

= 2 * 3/12 + 1 * 3/12

= 6/12 + 3/12

= 9/12

3(2/3) can be rewritten as

= 3 * 4/12 + 2 * 4/12

= 12/12 + 8/12

= 20/12

Now, our expression becomes:

6(11/12) - (9/12 + 20/12)

Next, let's add the fractions inside the parentheses:

= 9/12 + 20/12

= 29/12

Now, our expression becomes:

6 (11/12) - 29/12

To subtract the fractions, we again need a common denominator, which is 12 in this case.

6(11/12) can be rewritten as

= 6 * 12/12 + 11/12

= 72/12 + 11/12

= 83/12

Finally, we have:

83/12 - 29/12

Subtracting the fractions, we get 54/12.

Now, we simplify the result to a mixed number:

54/12 is equivalent to 4(6/12), which can be further reduced to 4(1/2).

So, the final answer is 4(1/2).

Answer: You would swap the ineqaulity

Step-by-step explanation:

Multiplying or dividing both sides by a negative number reverses the inequality. This means < changes to >, and vice versa. For example, given that 5 < 8 we can multiply both sides by 6 to obtain 30 < 48 which is still true.

Answer:

(8,0)

Step-by-step explanation:

y= 0.50x - 4

y= -0.25x + 2

I changed it to make it:

0.25x + y = 2

-0.50x + y = -4

--

We subtract the y's and every equation to cancel out the y.

0.25x - (-0.50x) = 0.75x

2-(-4)=6

0.75x = 6

x = 8.

Plug the x into either equation. We'll do the first eqn.

0.25(8)+y=2

2 = y = 2

y = 0.

(8,0).

Answer:

x = 8, y = 0

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y=\dfrac{1}{2}x-4&\\y=-\dfrac{1}{4}x+2\end{cases}[/tex]

First, substitute the first equation into the second:

[tex]\implies \dfrac{1}{2}x-4=-\dfrac{1}{4}x+2[/tex]

SOLVE FOR X.

Step 1: Multiply both sides by [tex]4[/tex] and simplify.

[tex]\\\implies 4\left(\dfrac{1}{2}x\right)-4(4)&=4\left(-\dfrac{1}{4}x\right)+2(4)\\\\\implies \dfrac{4}{2}x-16=-\dfrac{4}{4}x+8\\\\\implies 2x-16=-x+8[/tex]

Step 2: Add (1)[tex]x[/tex] to both sides.

[tex]\\\implies 2x + x-16=-x+x+8\\\\\implies 3x-16=8[/tex]

Step 3: Add [tex]16[/tex] to both sides.

[tex]\\\implies3x-16+16=8+16\\\\\implies 3x=24[/tex]

Step 4: Divide both sides by [tex]3[/tex].

[tex]\\\implies \dfrac{3x}{3}=\dfrac{24}{3}\\\\\implies \boxed{x=8}[/tex]

SOLVE FOR Y.

Step 1: Substitute [tex]8[/tex] as the value of [tex]x[/tex] in any of the given equations.

[tex]\\\implies y=\dfrac{1}{2}(8)-4[/tex]

Step 2: Simplify.

[tex]\\\implies y=4-4\\\\\implies \boxed{y=0}[/tex]

The solution to this system of equations is (8,0).

Step-by-step explanation:

If she was trying to make it 4 times bigger is multiply the length or the width by a factor of 4

If the starting measurements were

5ft long and 4 1/2 feet wide you simply multiply the two

5 x 4.5 = 22.5 ft

Then when trying to make it 4 times bigger multiply your answer by 4

22.5 x 4 = 90ft^2

Step-by-step explanation:

Answer:

b < 3071/390

Step-by-step explanation:

1) Multiply both sides by 100 :      3.9b x 100 + 3.29 x 100 < 34 x 100

2) Refine :      390b + 329 < 3400

3) Subtract 329 from both sides :      390b + 329 - 329 < 3400 - 329

4) Simplify :        390b < 3071

5) Divide both sides by 390 :       390b/390 < 3071/390

6) b < 3071/390

Answer:

$3.75

Step-by-step explanation:

Change 15% to a decimal by moving the decimal two places left.

15% = 0.15

Multiply

$25 x 0.15 = $3.75

The tip given by Tiana to the server is of $3.75 .

Given, that Tiana's bill is of $25 .

Total bill = $25

Tip to the server = 15%

Convert percent to fractions,

15% ⇒ 15/100

15% ⇒ 0.15

The tip is 15% of the total bill .

So, rewrite in form of equation,

15% of $25

= 0.15 × 25

= $3.75

Thus the tip to the server is of $3.75 .
