What is the value of x?<br><br><br><br> Enter your answer in the box.
Grace [21]
The shapes are similar.
When two figures are similar, the ratios of the lengths of their corresponding sides are equal.
Therefore,
\frac{42}{(15 + 42)} = \frac{x}{10 + x}

Simplify:
\frac{42}{57} = \frac{x}{10 + x}
Cross multiply:
42(10+x) = 57x
420 + 42x = 57x
420 = 57x - 42x
420 = 15x
x = (420÷15)
x = 28

Kaya used these steps to solve the equation 7 + 2x = 2(x - 1) + 4. Which choice describes the meaning of her result, 7 = 2?
Whitepunk [10]

Answer is A

7 + 2X = 2(X-1) + 4

7 + 2X = 2X-2+4

7 + 2X = 2X + 2 whether 2X = 2X-5  or 5 + 2X = 2X still  0 = 5 Or 0= -5 which is not possible

Which of the following situations results in an answer of 23 ? Select three that apply.
Nata [24]

Answer:

The first, second, and fourth questions.

Step-by-step explanation:

None of these result in an answer of 23, so I'm assuming that you meant 2/3.

<em />

<em>"Two gallons of water are needed to fill 3 fish tanks of equal size. How many gallons of water are required for each tank?"</em>

2 gallons divided between 3 tanks is 2 divided by 3, so 2/3.

<em />

<em>"Three cats share 2 cans of tuna. How much of a can does each cat receive?"</em>

2 cans divided between 3 cats - it's the same as the above problem, just with cats and tuna cans instead of tanks and gallons of water. Each cat gets 2/3 of a can.

<em />

<em>"Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?"</em>

2 bags divided between 5 parrots would be 2/5 of a bag for each parrot.

<em />

<em>"Two apples are split among 3 people. How much of an apple does each person receive?"</em>

Two apples split among 3 people - like the first 2 questions, this also equals 2/3.

<em />

<em>"Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?"</em>

Three dogs EACH drink 2 cups of water means that the answer is 2*3=6 cups.

<em>"Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?"</em>

Three cupcakes are split between 2 children - they will each get 3/2 of a cupcake, or 1 1/2.

Jasmine has only $46.50 to spend at forever 21. She wants to buy a shirt that costs $19, including tax, and some bracelets that
ivanzaharov [21]
46.50 - 19 = 5.50x

We get the 46.50 from her budget and the 19 from the shirt she wants to buy. If we subtract 19 from 46.50, we'll get the amount of money Jasmine can spend on bracelets.

46.50 - 19 = 27.50

She has $27.50 to spend on bracelets. Now, we divide that by 5.50 (the price of a bracelet) to see how many she can buy.

27.50 ÷ 5.50 = 5

Jasmine can buy 5 bracelets.

Hope this helps!
