(4w-8)+(3w+6)=180
7w-2=180
7w=180+2
7w=182
w=26
Answer:
x = -8/3
y = 4
Step-by-step explanation:
I assume you want to solve for x and y.
The best way to do this with the two formulas given is elimination. This means add the two equations together.
6x + 5y = 4
-6x + y = 20
The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with
6y = 24
Now solve for y by dividing both sides by the 6.
y = 24/6 = 4
Now that we have y, you can plug it into one of the equations and solve for x.
Let's use -6x + y =20.
So plug in the 4 for y to get -6x + 4 = 20
Subtract the 4 from both sides then solve for y by dividing both sides by the -6.
-6x = 16
x = -16/6
You can reduce that down so that x = -8/3.
Answer:
Options (A), (B) and (C)
Step-by-step explanation:
In the given figure,
Length of side AD = 16 units
If this side is scaled by a factor = k
Then the length of the corresponding side will be = 16k
If 0 < k < 1,
Then length of the corresponding side will be less than 16.
[Example: If k =
Therefore, scaled side of the corresponding side of the quadrilateral = = 4]
That means length of corresponding sides may be 4, 6.5 and 12.
Options (A), (B) and (C) will be the answer.
Answer:
k=5
Step-by-step explanation:
subtract 14 from both sides
36 is a perfect square, but its factors include 1 and 36, 6 and 6, 4 and 9, 3 and 12, and 2 and 18. that's 9 factors, not 3.
