Prove that the value of the expression: 731^2−631^2 is divisible by 100

Ivanshal [37]

Answer:

Step-by-step explanation:

731² - 631² is the difference of squares.

731² - 631² = (731+631)(731-631) = 1362×100

therefore, 731² - 631² is divisible by 100

Molly read 50 out of the 200 pages in her fiction book. Joel is also reading a fiction book, but his book has 280 pages in total

katrin [286]

Answer:

$x = 70$

Step-by-step explanation:

Given

Molly: 50 out of 200

Joel: x out of 280

Required

Find x

Start by representing the giving parameters as ration

Molly= 50 : 200

Joel = x : 280

From the question, the ratios are equivalent. So,

$50 : 200 = x : 280$

Convert to fractions

$\frac{50}{200} = \frac{x}{280}$

Solve for x

$x = \frac{50}{200} * 280$

$x = \frac{1}{4} * 280$

$x = \frac{280}{4}$

$x = 70$

What value of x gives y=-2?<br><br> plz help !

Ivanshal [37]

Answer:

-1

Step-by-step explanation:

to find x, use the following formula:

y = mx + b

(y = 0)

(m = change in y-value ... which is 2)

(x = change in x-value ... which is 2)

(b = y-axis ... which is -2)

y = mx + b

y = $\frac{2}{2}$ + -2

$\frac{2}{2}$ = 1

y = 1 + -2

y = -1
