First lets put these numbers into improper fractions. 4 2/5 becomes 22/5 becomes we multiple the 4 by the denominator,5, and add to the dividend.
We do the same process with 16 1/2 and get 33/2.
We then need to set these equations so that they have the same base. In these case a common factor is 10.
We multiple our first equation by 2 and get 44/10, and then we multiple our second equation by 5 and get 165/10.
We then setup the equation (44/10)*x=165/10
We can multiple each side out by 10, leaving us 44x=165
Divide each side by 44, which leaves us with x=165/4
When you simiplify the problem we are left with x and our answer.
When done correctly you will find that it takes 3 3/4 minutes to fill a tank that holds 16 1/2 gallons.
Answer: The square root of 8 is expressed as √8 in the radical form and as (8)½ or (8)0.5 in the exponent form. The square root of 8 rounded up to 8 decimal places is 2.82842712. It is the positive solution of the equation x2 = 8.
Step-by-step explanation:
Answer:
(-3, -2)
Step-by-step explanation:
Look at the second equation, we can easily rearrange it to make x the subject.
x - 4y = 5
x = 4y + 5
Now lets put that into the second equation
2x - 2y = -2
2(4y + 5) - 2y = -2
6y + 10 = -2
6y = -12
y = -2
Now lets find x!
x = 4y + 5
x = 4(-2) + 5
x = -3
Now lets format the answer like the question says (ordered pair)
(-3, -2)
Recap: We used substitution and made an equation to work out one of the variables first, then found the second variable using the first.
Answer:
Step-by-step explanation:
y+1 =(3/4)x+9/4
y=(3/4)x+1/4
If the question is, what is it? It is called this figure a pencil of lines.
А pencil of lines can consist of any number of straight, the main thing that they all had one common point. Here you can find a lot of vertical angles and rays.
