What are some examples of how you have used, or could use, algebraic equations to solve problems in your everyday life?
pshichka [43]
We use algebraic equations in our daily lives without knowing it. For example, when we go shopping, calculate grocery expenses, or even fill our gas tanks, we are using equations. Let's say we needed to fill our gas tank, but we only had $15.00 to do so. If the price of gas is $3.00 per gallon, how many gallons could we buy? We use the simply algebraic equation of \frac{x}{y} to calculate the total gallons that can be bought. x = the money we have. y = price per gallon of gas. \frac{15}{3} = 5. So with $15.00, we can buy 5 gallons of gas; and that is just one example of using an algebraic equation in everyday life!

(a+b)²=d<br> Isolate a on one side
PilotLPTM [1.2K]

Answer:

a=sqrt(d)-b, a=-sqrt(d)-b

Step-by-step explanation:

(a+b)^2=d

(a+b)=sqrt(d)

a+b=sqrt(d), a+b=-sqrt(d)

a=sqrt(d)-b, a=-sqrt(d)-b

There is a 4 digit number that when multiplied by 4 is the reverse.
mote1985 [20]

Answer:

The answer is 2178, if you multiply it by 4, you would get 8717

Step-by-step explanation:

HERE ARE THE STEPS IF YOU NEED THEM!!

1. Lets say the number is written as ABCD (1000a+100b+10c+d).

2.Multiplying it by 4, gives you DCBA (1000d+100c+10b+a)

3. By divisibility of 4, BA is a two-digit number divisible by 4.

4.Now, the largest possible value of ABCD is 2499, because anything more will result in a five digit number when multiplied by 4.

5. Out of the two possibilites 1 and 2 for A, [3] follows that A is even, so 2.

6. From [5], D is either 8 or 9. However, since D times 4 would end in 2, D is 8.

7. Using [2], 4000a+400b+40c+4d = 1000d+100c+10b+a, which would simplify to 2c-13b = 1 after substituting A = 2 and D = 8.

8.The only possible value of (b,c) where they would both be single digit integers is (1,7). Also to note from [3], B is odd. And from [4], B is either 1 or 3.
