Answer:

7/22

Step-by-step explanation:

Step 1: Define/explain.

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: Solve.

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22

22 is the LCM.

Now, we change the fractions to where they both have denominators of 22.

**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**

$9/11*2/2=18/22$

$1/2*11/11=11/22$

Now, subtract as normal.

$18/22-11/22=7/22$

$7/22 (simplified).$

Step 3: Conclude.

Therefore, 9/11 - 1/2 = 7/22.

Lee and two friends shared a pizza. She also bought a lemonade for $2.25. Lee's share of the bill was $7.25.What was the total c

GaryK [48]

Answer:

$15

Step-by-step explanation:

You first need to subtract 2.25 from 7.25 which leaves you with 5 dollars. Since Lee's share of the pizza cost 5 dollars, and 3 people ate the pizza, you need to multiply 5*3 and get 15 dollars. This is the total pizza cost.

For question 4, $x = 18$ units,

For question 5, $x = 8.333$ units.

Step-by-step explanation:

Step 1:

Since the given polygons are similar to each other, all the ratios of one polygon to the other will remain equal for all the values of the two similar polygons.

We take the ratio of the same sides of both polygons i.e. the ratio of the lengths or the ratio of the widths.

Step 2:

For question 4, the first rectangle has a length of 9 units while the width is 3 units.

For the second rectangle, the length is x as x is greater than the width in the first rectangle. The width is 6 units.

The ratio of the first rectangle to the second is;

$\frac{3}{6} : \frac{9}{x} , x = (9)(\frac{6}{3} ) = 18.$ So $x = 18$ units.

Step 3:

The shapes in question 5 are made of a square and a triangle.

For the first shape, the side length is 6 units while the side of the triangle is 10 units.

For the second shape, the side length is 5 units while the side of the triangle is x units.

The ratio of the first shape to the second is;

$\frac{6}{5} : \frac{10}{x} , x = (10)(\frac{5}{6} ) = 8.333.$ So $x = 8.333$ units.

in a recent year, one united states dollar was equal to about 82 japanese.how many japanese yen are equal $100?$1,000?$10,000?

Ugo [173]

$\sf 1 ~dollar = 82~yens\\\\100~dollars = 82 \times 100~yens= 8,200~yens\\\\ 1,000~dollars = 82 \times 1,000~yens = 82,000~yens\\\\10,000~dollars=82\times10,000~yens=820,000~yens$

Lyrx [107]

The correct answer for this question is this one: "y = -x + 2"

 y - intercept = (0,2) slope = -1

y = mx + b
2 = -1 (0) + b
b = 2

so the equation of the line is
y = -x + 2
Hope this helps answer your question and have a nice day ahead.

2+d=2-3(d-5)-2 Pls show work

defon

2 + d = 2 - 3(d- 5) - 2

First, cancel 2 on both sides. / Your problem should look like: $d = -3(d - 5) - 2$
Second, expand. / Your problem should look like: $d = -3d + 15 - 2$
Third, simplify -3d + 15 - 2 to get -3d + 13. / Your problem should look like: $d = -3d + 13$
Fourth, add 3d to both sides. / Your problem should look like: $d + 3d = 13$
Fifth, add d + 3d to get 4d. / Your problem should look like: $4d = 13$
Sixth, divide both sides by 4. / Your problem should look like: $d = \frac{13}{4}$

Answer as fraction: $d = \frac{13}{4}$
Answer as decimal: $d = 3.25$
