Answer:
x = 20
Step-by-step explanation:
The three angles make up a straight line.
A straight line has 180 degrees.
x + 3x + 100 = x80 Combine
4x + 100 = 180 Subtract 100 from both sides
4x = 180 - 100
4x = 80 Divide by 4
x = 80/4
x = 20
At least means it can be larger than or equal to.
X >= 15
No more than means less than or equal to:
X <= $7
Answer:
1. Y = 2, 1, 4, 7, 10
2. Y = -12, -8, -4, 0, 4
3. Y = -7, -5, -3, -1, 1
Step-by-step explanation:
all of the numbers in the x value you just substitute in the x place in problem
1. Y = 3x + 4
x: -2, -1, 0, 1, 2
Y = 3(-2) + 4
Y = -6 + 4
Y = -2
You then have:
x: -2, -1, 0, 1, 2
y: -2,
Y = 3(-1) + 4
Y = -3 + 4
Y = 1
You then have:
x: -2, -1, 0, 1, 2
y: -2, 1
just continue substituting each x variable into the x place to get your y variable.
I know you asked for the first 6 but I feel like if I just give you the answers to all of them you will not learn it, so I only gave the first 3, and I recommend trying to do the last 3 yourself. I'm sure you'll do well. <3
I think your answer would be less than (I'm not really good at math so sorry if you get it wrong ;v) Hope I helped :]
5 * 3/10?
If this is correct then this is pretty easy...
Because 5/1 = 5 we can make it 5/1 to make multiplication easier.
5/1 * 3/10
5*3=15
1*10=10
The answer is 15/10.
15 and 10 are both divisible by three.
The reduced answer is 3/2.
