Answer:

10100

Step-by-step explanation:

Use this formula,

\frac{n}{2} (2 {a} + d(n - 1)

where n is the amount of even intergers, a is the starting term, d is the common difference.

  • the amount of even intergers from 2 to 200 is 100
  • The starting number is 2
  • The common difference is 2

\frac{100}{2} (4 + 2(99)

50(4 + 198)

50(202)

10100

I NEED THE ANSWER ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!<br><br><br><br><br> 1/7-3(3/7x-2/7)
melomori [17]

Step-by-step explanation:

x in (-oo:+oo)

1/7-(3*((3/7)*x-(2/7))) = 0

1/7-3*((3/7)*x-2/7) = 0

1/7-3*(3/7*x-2/7) = 0

(-3*7*(3/7*x-2/7))/7+1/7 = 0

1-3*7*(3/7*x-2/7) = 0

7-9*x = 0

(7-9*x)/7 = 0

(7-9*x)/7 = 0 // * 7

7-9*x = 0

7-9*x = 0 // - 7

-9*x = -7 // : -9

x = -7/(-9)

x = 7/9

x = 7/9

Converting units is always an exercise in linear relationships. how many inches is 2.50 m? (2.54 cm=1.0 inch)
madam [21]

There are 98.4252 inches in 2.50m.

Unit Conversion is defined as a process that involves multiplication and division by a numerical factor or a particular conversion factor.

For Example .Convert 2m into cm.

As we know that 1m=100cm

multiplying both sides by 2 we get

2m = 200 cm.

According to the question

It is given that 2.54 cm = 1 inch

1cm = \frac{1}{2.54} inch

100cm=\frac{100}{254} inch

1m = \frac{100}{2.54} ( as 100cm = 1m)

we need 2.50 m So we multiply both sides by 2.50

2.50m=\frac{2.50*100}{2.54} \\\\  2.50m=\frac{250}{2.54}

2.50m=98.4252 inch

Therefore , there are 98.4252 inches in 2.50m.
