Answer:
The answer is 600000
Step-by-step explanation:
"kilo" means 1000, so you add 3 zeros in the end. Hope this helped!
Put common terms in evidence and simplify:
Answer:
2nd one
Step-by-step explanation:
(90 x 5) - 3 = 447
-25 15/19 + 9/1
get a common denominator of 19
they multiplied 9/1 * 19/19 = 171/19
-25 15/19 + 171/19 =
change the mixed number to an improper fraction
(19* 25 +15)/19 = 490/19
-490/19 + 171/19 =
add together
-319/19
now convert the improper fraction back to a mixed number
19* 16 =304 319-304=15
-319/19 =-16 15/19
AREA OF A RECTANGLE IS 42 UNITS
Rectangle: Triangle:
A = L * W A = hb / 2
A = (x-8) * 6 A = (7(x-3)) / 2
A = 6x - 48 A = (7x - 21) / 2
Since the problem states that both rectangle and triangle have the same area.Then:
6x - 48 = (7x - 21) / 2
1) Eliminate the denominator 2 by multiplying both sides by 2.
2 * (6x - 48) = 2 * ((7x - 21) / 2)
12 x - 96 = 7x - 21
Find x. Transfer like numbers and change their signs.
12x - 7x = 96 - 21
5x = 75
5x / 5 = 75 / 5
x = 15
Substitute x by its value:
Rectangle: Triangle
A = (x-8) * 6 - A = (7(x-3)) / 2 Areas of both Rectangle
A = (15 -8 ) * 6 A = (7(15-3)) / 2 and Triangle is the same.
A = 7 * 6 A = (7 * 12) / 2
A = 42 units A = 84 / 2
A = 42 units
