Julli [10]3 years ago

What you do to on side of an equation (=) you must do to the other to keep both sides equal.

r3-2+2=+2  (add 2 to both sides of the equation to simplify the left side)
which becomes
r3=2
r3/3 = 2/3 (divide both sides by 3) Note 3/3 =1 and 1 r is the same as r
which becomes
r=2/3 .

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

One positive number is 5 times another number . The difference between the two numbers is 80, Find the numbers.
nika2105 [10]
---------------------------------------------------------------------------------------------------
Define the numbers:
---------------------------------------------------------------------------------------------------
Let x be one number.
One number = x
Other number = 5x

---------------------------------------------------------------------------------------------------
Construct the equation:
---------------------------------------------------------------------------------------------------
5x - x  = 80

---------------------------------------------------------------------------------------------------
Combine like terms:
---------------------------------------------------------------------------------------------------
4x = 80

---------------------------------------------------------------------------------------------------
Divide by 4 on both sides:
---------------------------------------------------------------------------------------------------
x = 20

---------------------------------------------------------------------------------------------------
Find the 2 numbers:
---------------------------------------------------------------------------------------------------
One number = x = 20
Other number = 5x = 5(20) = 100

---------------------------------------------------------------------------------------------------
Answer: The two numbers in increasing order are 20 and 100.
