Her speed is increasing between A) 0 - 10 minutes.

You can see this because the graph line is inclining. Everywhere else it is either staying the same (her speed is neither increasing or decreasing) or declining ( slowing down).

20 - 25 she is decreasing.
10 - 20 she is going the same speed.

The product of two numbers is 240. The first number is 8 less than the second number. Write an equation can be used to find x

DaniilM [7]

Answer:

The equation x = y-8

The equation (y-8) y = 240

The first number x = 12 and second number y =20

Step-by-step explanation:

Explanation:-

Step(l):-

Let 'x' be the first number and 'y' be the second number

Given the product of two numbers is 240

Given data x y = 240 …(l)

Given data the first number is 8 less than the second number.

x = y-8...(ll)

Substitute (ll) in equation (l) , we get

(y-8) y = 240

$y^{2} -8y -240 =0$

$y^{2} -20y+12y -240 =0$

$y(y -20)+12(y -20) =0$

$(y +12)(y -20) =0$

y = -12 and y = 20

Y= -12 is not satisfied

we can choose y = 20

Step(ll):-

Given data x =y-8

substitute value y = 20 in x = y -8

x = 20-8 = 12

Final answer:-

The first number x = 12 and second number y =20

The division is using extra zeros.
2 * 16 = 32, but 3200 was placed below 3426.

Now 1 * 16 = 16, so 160 goes below 226.
The number that goes in the box is 160.
