9. AABC and ADEF are similar. Find the values of x and y. (1 point)


A. x=7, y = 12
B. x=21, y = 12
C. x= 14, y = 18
D. x=7, y = 18

Answer:

$13.64

Step-by-step explanation:

38/100 cross multiplied by x/22 multiply 22 and 38, then divide by 100

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:

19.4

Step-by-step explanation:

23.8-4.4=19.4

Answer: 12%

Step-by-step explanation:

Total number of people in 6th grade: 70+80 = 150

Total numbers of lefties: 11 + 7 = 18

Percent:

18 ÷ 150 = 0.12

0.12 x 100 = 12

Answer:

12%

Step-by-step explanation:

80+70=150 which is the whole

11+7= 18 which is the part

The equation is

Part= Percent x Whole

18= % x 150 or 18 divided by 150 is

.12 or 12%

Step-by-step explanation:

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).

Answer:

x(b) or b(x)

Step-by-step explanation:

x for the number of people who suggested.

b for the number of bracelets given.

The bracelets are not needed in this equation because they do not relate the the total amount of donations collected.

let's first introduce some variables:

let p= the number of people

let d= the suggested amount of of donation

equation:

number of people × suggested amount of donation

d×p

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:

4.75 seconds

Step-by-step explanation:

14.7 - 9.95

Answer:

The Olympian completed the 100-meter dash 4.75 seconds faster than the gym teacher. You could also say he was 3.25 meters per second faster.

Step-by-step explanation:

To get 4.75 I just subtracted and found the difference between both of their times.

To find the difference between their speeds, I divided 100 by each time to get each person's distance per second. The olympian's speed was 10.05 meters per second and the gym teacher's speed was 6.80 meters per second. To find the difference between these, I subtracted the same way I did with the time difference.

Answer:

90ft^2

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

I belive its 15

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 .
