Chad drove 168 miles in 3 hours. How many miles per hour did Chad drive?

Answers

Answer 1

Answer:

°° Let's see -

Basically, you divide the number of miles Chad drove by the number of hours it took. Then, it gives you the number of miles Chad drove in one hour. Let's try it!

168 ÷ 3 = 56

You can now see that Chad drove 56 miles in one hour.

Solve each quadratic equation by factoring. 6n^2-18n-18=6

Answers

Divide by 6 to get:

n^2-3n-3=1

Subtracting 1, we see that:

n^2-3n-4=0

Factoring, we have:

(n-4)(n+1)=0

Therefore, 4 and -1 are the solutions, since if either n-4 or n+1 is zero, the whole expression is zero.

$6n^(2)-18n-18=6 \n \n 6n^(2)-18n-24=0 \n \n 6(n^(2)-3n-4)=0 \n \n n^(2)-3n-4=0 \n \n n^(2)-4n+n-4=0 \n \n n(n-4)+(n-4)=0 \n \n (n+1)(n-4)=0 \n \n n+1=0 \ \vee \ n-4=0 \n \n n=-1 \ \vee \ n=4 \n \n n\in \lbrace -1,4 \rbrace$

What is the quotient of 6 and -1/5?

Answers

Answer:

The quotient of 6 and -1/5 is -30.

Step-by-step explanation:

Consider the provided information.

We need to find the quotient of 6 and -1/5

To find the quotient of 6 and -1/5 divide them as shown.

Translate the provided statement.

$6/ (-1)/(5)$

$(6)/(-(1)/(5))$

$=-6* 5$

$=-30$

Hence, the quotient of 6 and -1/5 is -30.

What really helps is looking at it like a positive and negative number line. Adding a negative is the same as subtracting a positive, and visa versa. The quotient is 5.8

Adding fractions and decimos

Answers

To add a fraction, you add the numerator(topnumber) to the other numerator. You also add the denominator(bottomnumber) to the other denominator. If the denominators are not alike, youhave to find the LCD and change the fractions, so that they are alike.For example:
1/2 +3/4
The denominators are unalike. So you have tofind the LCD (Least Common Denominator). The LCD is 4. Since 3/4already has 4 as the denominator, you only have to change 1/2. Youchange the 2 to 4, so it will look like this: 1/4. You still aren'tdone. You need to change the numerator. Since you multiply 2 by 2 to getfour, you need to multiply 1 by 2. Now you have:
2/4+3/4 You add and get:
5/4
Since this is an improper fraction, you have to simplify it. You divide the numerator by the denominator:
5 divided by 4 is 1 with 1 left over. You turn it into a fraction. So your answer is 1 1/4.

For decimals, you align the numbers then add.
1.34 + 56.2

1.34 See how I aligned the decimal points?
+56.2 That is how you align decimals. Now you just add.
