QUESTION 1 OF 5<br> 10(23+ 7) = 100l + 100l<br> What is the value of l in the equation above?

aalyn [17]

Answer:

1.5

Step-by-step explanation:

An equation 10(23+7)=100ℓ+100ℓ is given and we are asked to find the value of ℓ.

To solve the equation, we have to move all the values containing ℓ on one side and other values on other side of equality.

10(23+7)=100ℓ+100ℓ

Multiply 10 with 23 and 7 which gives

(10 * 23 ) + ( 10 * 7) = 200 ℓ

Solving the above equation,

230 + 70 = 200 ℓ

300 = 200 ℓ

=> ℓ = 300 / 200

=> ℓ = 3/2

=> ℓ = 1.5

The difference between the roots of the quadratic equation x2+x+c=0 is 6. Find c.

NemiM [27]

We have that
$x_{1} - x_{2} = 6$
Let y be the first root, then y - 6 will be the second one. Since both roots make the quadratic equation equal to 0, we have that:
$y^{2} + y + c = (y - 6)^{2} + (y - 6) +c$
Solve for y:
$y^{2} +y +c = y^{2} - 12y + 36 + y - 6 +c \\ y + 12y - y = 30 \\ y = \frac{5}{2}$
Plug in y = 5/2 into original quadratic equation and solve for c:
$( \frac{5}{2}) ^{2} + \frac{5}{2} +c = 0 \\ c= - \frac{5}{2} - \frac{25}{4} \\ c = - \frac{35}{4}$
So, the answer is c = -35/4

The attendance at Southview High School's seven home football games was as follows: 575, 630, 720, 575, 525, 623, and 692. What

Nutka1998 [239]

Mode=most
1) order the numbers from least to greatest
525,575,575,623,630,and 692
2)Any number that is repeated it is the mode if there is no number repeated there is no mode.
3)575 is repeated the most so that is your mode

Hope It Helps!
