if hayden and uri have 1250, and hayden and willow have 830, and uri has 4 times more than willow. how much does hayden have​
svp [43]

Answer:

690

Step-by-step explanation:

Let

hayden have "h"

uri have "u"

and

willow have "w"

Hayden & Uri have 1250. we can write:

h + u = 1250

Hayden & Willow have 830, so we can write:

h + w = 830

Uri has 4 times than Willow, so we can write:

u = 4w

Putting 3rd equation in first, we get:

h + u = 1250

h + 4w = 1250

Now, we take 2nd and 4th equation, which are:

h + w = 830

h + 4w = 1250

Multiplying this first one with -1, gives us:

-1 * [h+w=830] = -h - w = -830

Now we add this up with 4th equation. Shown below:

- h - w = - 830

h + 4w = 1250

----------------------

4w - w = 1250 - 830

3w = 420

w = 420/3

w = 140

We know u = 4w, so u = 4 * 140 = 560

u = 560

Also, we know h + w = 830, so

h + 140 = 830

h = 830 - 140

h = 690

Thus Hayden has 690

An explosion causes debris to rise vertically with an initial velocity of 160 feet per second. What is the speed of debris when
lisov135 [29]
The question is asking what v_final is, given that v_initial is at 300 feet. and v_initial is at 0 feet.  
We know there will be a constant downward acceleration of 32.15 ft/s^2.
 Use the following equation: 
 v_final^2 = v_initial^2 + 2ah
 v_final^2 = (160 ft/s)^2 + 2(-32.15 ft/s^2)(300 ft) = 6310 ft^2/s^2
 v_final = (6310 ft^2/s^2)^1/2 = 79.4 ft/s.

In a family, each brother has as many sisters as brothers, but each sister has twice as many brothers as she has sisters. How ma
daser333 [38]

Answer:

4 brothers and 3 sisters

Step-by-step explanation:

Let x be the number of brothers and y be the number of sisters in the family.

1.  Each brother has x-1 brothers and y sisters. If each brother has as many sisters as brothers, then

x-1=y.

2. Each sister has y-1 sisters and x brothers. If each sister has twice as many brothers as she has sisters, then

2(y-1)=x.

3. Solve the system of two equations:

\left\{\begin{array}{l}x-1=y\\ \\2(y-1)=x\end{array}\right.\Rightarrow 2(y-1)-1=y,\\ \\2y-2-1=y,\\ \\2y-y=2+1,\\ \\y=3.

Then

x=y+1=3+1=4.
