Answer:
by exterior angle sum property
(ext ang.F=ang G + ang H)
Step-by-step explanation:
therefore,
- 14x+1=89+(5x-7)
- 14x+5x=89-7+1
- 19x=90-7
- 19x=83
- x=83/19
- x=4.36(approx)
Answer:
every number you can think of
Step-by-step explanation:
6x - 3y = -6
=> 3(2x - y) = -6
=> 2x - y = -2
And you see there's a problem here. The question doesn't have enough information because x and y can be every numbers.
Take an example, x can be 200 and y can be 402 or x can be 5 and y can be 12.
Rewrite or check the question again so I can solve this :)
Given the equation:
Step 1: Factor -2 out of the variable terms
Step 2: Divide both sides by -2.
Answer:
63
Step-by-step explanation:
A composite number is a whole number. It can be defined as a number that is divisible by 1, itself and other factors. This means a composite number has two or more factors. A prime number cannot be a composite number.
The seven smallest composite numbers are:
4, 6, 8, 9, 10, 14, 16,
Their total sum = 4 + 6 + 8 + 9 + 10 + 14 + 16 = 63
Therefore, the sum of the seven smallest composite numbers which cannot be determined to be composite simply by using the divisibility rules (for 2,3,4,5,6,8,9 or 10) is 63.
Answer:
-7/15
Step-by-step explanation:
You want to isolate the d variable so you take out anything on the side of d to make d alone. To make d isolate the 15/42 has to go.
So...multiply
* right side
the answer to the equation above is 1. d is now alone, because 1*d is just d.
Since you multiplied 42/15 on the right, you've to do the same thing on the left.
* left side
Divide the 6 by itself and also by 42. Or multiply the numerator and denominator.
The answer you get is -7/15.
