Jamie's age is n. (given)

Brian's age is 2n. (given)

Half of Brian and Jamie's present age is (n +2n)/2 = 3n/2.

Let m represent Morgan's age now. Then

... m + 8 = 2 + 3n/2 . . . . . in 8 years, Morgan's age will be 2 more than ...

Subtract 8 to find Morgan's present age:

... m = 3n/2 - 6 . . . . Morgan's present age

A map has a scale of 1.5 in : 26 mi. If the distance between city A and City
alekssr [168]

Answer:

The real distance is 260 miles

Step-by-step explanation:

From the question;

1.5 inches in map is 26 miles

Thus;

15 inches will be x miles

To get the value of x, we do a cross-multiplication

we have this as:

15 * 26 = 1.5 * x

x = (15 * 26)/1.5

x = 10 * 26 = 260 miles

For the shaded bit all you need to do is 8.5 × 6.
if you are to get the other bit then do 8.5 × 8
if it is to be both then just do that and add them together

What is 6 divide by 2 times 3 times 100 multiply by 700 and divide by 1.37 and multiply by 0.778 and then add 0.778913 times 100
3241004551 [841]

Answer:

~460032.8

Step-by-step explanation:

Essentially, when this is written out, we get:

6 ÷ 2 × 3 × 100 × 700 ÷ 1.37 × 0.778 + 0.778913 × 100 × 10 × 1.77 × 444444.47 ÷ 7777777.0999 + 100

Order of operations says to do multiplication and division first, so let's calculate 6 ÷ 2 × 3 × 100 × 700 ÷ 1.37 × 0.778 separately:

6 ÷ 2 = 3

3 × 3 = 9

9 × 100 = 900

900 × 700 = 630000

630000 ÷ 1.37 = 459854

459854 × 0.778 = 357766

Now calculate 0.778913 × 100 × 10 × 1.77 × 444444.47 ÷ 7777777.0999:

0.778913 × 100 × 10 × 1.77 × 444444.47 = 612744929

612744929 ÷ 7777777.0999 ≈ 78.78

Add these all up:

357766 + 78.78 + 100 ≈ 460032.8
