Answer: x = 9 -3y
Step-by-step explanation:
Hi, to answer this question we have to solve the system by substitution:
a)3x − 4y = 12
b)2x + 6y = 18
If we isolate "y" on b)
2x + 6y = 18
2x = 18 -6y
x = 18/2 - 6/2y
x = 9 -3y is a possible equation
Doing the same thing with the other equation a) , and isolating "y" in both expressions, the only possible equation is the one founded above.
Answer:
k = -7
Step-by-step explanation:
2k+3k-13=-48
5k - 13 = -48
5k = -48 + 13
5k = -35
k = -7
200,000 + 10,000 + 3,000 + 400 + 10 + 6 + 0.1 + 0.06
Answer: x=1.5811389999999999 , or 1.59
Step-by-step explanation:
First, Subtract 20 from both sides.
12x2+20−20=50−20
12x2=30
Then, Divide both sides by 12:
12x^2/12 = 30/12
⇒ you get : x^2 = 5/2
After, Take square root.
x= ± √ 5/2
Finally you answer is going to be =1.5811389999999999 OR, 1.59

Answer:
Answer: 6^2
Step-by-step explanation:
Givens
- Express the integers raised to a power as integers.
- 10^2 = 100
- 4^3 = 64
Solution
- Subtract 64 (which is 4^3) from 100. See if what is left is a power of 6
- 100 - 64 = 36 Yes the remainder is 36
- 36 = 6*6 = 6^2
