Answer:

4. -12, 5. 9, 6. 17

Step-by-step explanation:

Since they're all integers, the negative numbers are on the left side and the positive integers are on the right. Therefore the opposites would be -12 for number 4, 9 for number 5, and 17 for number 6.

What the answer to this equation be?
scoray [572]

If you expand the square, you have

\dfrac{1}{4}x^2-3x=7x+8-10x

Simplify the right hand side:

\dfrac{1}{4}x^2-3x=-3x+8

Cancel the -3x appearing on both sides:

\dfrac{1}{4}x^2=8

Multiply both sides by 4:

x^2=32

Consider the square root of both terms (using the doubles sign):

x=\pm\sqrt{32}=\pm4\sqrt{2}

Goryan [66]

Answer:

\large \boxed{\sf \ \ 69 \ \textbf{touchdowns } 11 \ \textbf{field goals } \ }

Step-by-step explanation:

Hello,

Touchdown is 7 points, field goals is 3 points

Let's note a the number of touchdowns and b the number of field goals, we can write

   (1)    a + b = 80

   (2)    7a + 3b = 516

(2) - 3*(1) gives

7a + 3b - 3(a + b) = 516 - 3*80

<=> 7a + 3b -3a - 3b = 516 - 240 = 276

<=> 4a = 276

<=> a=\dfrac{276}{4}=69

And then from (1) b = 80 - 69 = 11

Hope this helps
