The correct answer is C, hope it’s right :)
To convert Hectometers to kilometers you divide by 10:
8.7 / 10 = 0.87 kilometer
8.7 hectometers = 87 kilometers = FALSE.
Multiply centigrams by 10 to get milligrams:
4.02 x 10 = 40.2
4.02 centigrams = 40.2 milligrams = TRUE.
Milliliter to liter:
Divide milliliters by 1000:
0.001 / 1000 = 0.000001
0.001 milliliter = 0.1 liter = FALSE.
Meter to kilometer:
Divide meters by 1000:
0.004 / 1000 = 0.000004
0.004 meter = 0.000004 kilometer = TRUE.
Answer:
x = 4.7
Step-by-step explanation:
30x - 140 -(x - 4)
Multiply the -1 into (x - 4)
30x - 140 - x + 4
Add/subtract
29x - 136 = 0
+136
Option B is correct. The required expression on expansion of 20х-[2х -(х+2)-(6-x 2 )-(28 +x+x2] is 20x + 36
Expressions are function that does not include "equal" sign
Given the expression
20х-[2х -(х+2)-(6-x² )-(28 +x+x2]
Expand and collect the like terms
= 20х-[2х -х-2-6+x² -28 - x - x²]
= 20x - [x - 8 + x² - 28 - x - x² ]
x and x² cancels out from the expression to have
= 20x - [- 8 - 28]
= 20x -(-36)
= 20x + 36
Hence the required expression on expansion is 20x + 36
