B.(0.5,5)
C.(8,-1)
D.(5,0.5)

Answers

Answer:

C. (8, -1)

Step-by-step explanation:

{y = ¼x - 3}

{2x + 4y = 12

2x + 4[¼x - 3] = 12

2x + x - 12 = 12

3x - 12 = 12

+ 12+ 12

The ratio of points scored by 3 boys in a game is 7:10:12. If the sum of their scores is 232, what was the highest score?

Answers

Answer:

96 points

Step-by-step explanation:

Ratio problems can be solved like this:

Let x equal an unknown value.

Now, we can write an equation.

7x + 10x +12x = 232

We want to find 12x, so we have to find x first. We can simplify our equation to:

29x = 232

Now, divide both sides by 29.

x=8

We then solve for 12x by multiplying 8 and 12, and get 96 points.

Write a word phrase for each algebraic expression 25-0.6x

Answers

The word phrase for each algebraic expression 25-0.6x is twenty five minus  zero point six. multiply x ( the unknown numerical value).

What is word phrase?

A word phrase is a collection of two or more words that together communicate one thought, but do not constitute a whole sentence.

The word phrase of "25" is twenty five.

The word phrase of "-"is minus.

The word phrase of "0.6" is zero point six.

And x is any unknown numerical number.

0.6x means the two numbers are multiplied.

So,  the word phrase of "25-0.6x" is twenty five minus  zero point six multiply x ( the unknown numerical value).

So, the word phrase of "0.6x" is zero point six multiply x ( the unknown numerical value).

Therefore, the word phrase for each algebraic expression 25-0.6x is twenty five minus  zero point six multiply x ( the unknown numerical value).

Find three consecutive even integers such that the sum of the smallest to the largest 36

Answers


If they were all the same integer, then each one would be
1/3 of 36, and you would have

                                           12  +  12  +  12  =  36 .

But you don't want them to all be the same number.  You
want them to be three consecutive even numbers.

Fine !  Take 2 away from the first 12, and glue it onto the last 12 .
Their sum doesn't change, but now you have

                                             10  +  12  +  14  =  36 .
First, I would set up an equation (assuming 36 is the sum of all 3 numbers). 

x+(x+2)+(x+4)=36
               3x+6=36
                   -6   -6
                   3x=30
                   ---   ---
                   3     3
                   x=10

Now, we just plug in the numbers to find the consecutive integers
10+(10+2)+(10+4)
10+12+14

So your 3 consecutive even integers are 10,12 and 14
