Xavier is x years old and Yvonne is y years old. Yvonne is 7 years older than Xavier. Four times Yvonne’s age is equal to 200. (a) Write an equation that could be used to solve for Yvonne’s age, y. (b) How old is Yvonne? Show your work and don’t forget the unit. (c) How old is Xavier? Show your work and don’t forget the unit

Answers

x+7= Yvonne's age.

a. 4(x+7)=200

b. 4(x+7)=200
4x+28=200
4x=172
x=43
Yvonne is 43 years old.

c. 43-7=Xavier's age.
36
Xavier is 36 years old.
You would have to write an equation. I would use the equation 4y=200. Thats your answer for (a). Then reverse the equation and solve to figure out the answer to (b). What we do to one side we do to other, right? So we would divide each side by 4. That leaves us with y=50. There's your answer to (b). Now to find Xavier's age we would simply do Yvonne's age minus 7. 50-7=43. There's your answer to (c).
A) 4y=200
B) 50 years old
C) 43 years old
Hope this helps!!!!

Show your work x2 – 2x – 35 = 0

Answers

Answer:

x=7     x=-5

Step-by-step explanation:

x^2 – 2x – 35 = 0

Factor

What 2 numbers multiply to -35 and add to -2

-7*5 = -35

-7+5 = -2

(x-7) (x+5) =0

Using the zero product property

x-7 =0       x+5=0

x-7+7=0+7      x+5-5=0-5

x=7     x=-5

In the continental United States,the ratio of states that border an ocean is 7:9 .How many of the states border an ocean?

Answers

Answer:  21 states

Step-by-step explanation:

Since, The total number of states in the continental United States is 48 in which some are in the border of ocean and some are not in the border of ocean.

According to the question,

The ratio of the states having the border to the ocean and not having the border to the the ocean = 7 : 9

Let the states having the border to the ocean = 7x

The the states do not having the border to the ocean = 9x

Thus,  7x + 9x = 48

⇒ 16 x = 48

⇒ x = 3

Thus, the states having the border to the ocean = 7 × 3 = 21

In the continental United States, the number of states that border an ocean is 7/16 of the total number of states.

To find the number of states that border an ocean, we need to determine the specific values that correspond to the ratio. Let's denote the number of states that border an ocean as 7x and the number of states that do not border an ocean as 9x, where x is a common factor.

According to the given ratio, the equation is:

7x : 9x

To simplify the ratio, we can divide both sides by x:

7 : 9

Now, we can analyze the ratio. Since it is stated that the ratio applies to the continental United States, the total number of states is irrelevant. We are only concerned with the proportion of states that border an ocean to those that do not.

Based on the simplified ratio of 7:9, we can conclude that out of every 16 states, 7 of them border an ocean while the remaining 9 do not.

Therefore, in the continental United States, the number of states that border an ocean is (7/16) of the total number of states.
