That factor is odd because if the last number is odd the whole number is odd
Answer: The largest angle is 7x
Step-by-step explanation:
Their sum is 180, so
3x + 5x + 7x = 180
5x = 180 --> x = 12
The largest angle is 7x, which is 7(12) = 84
3 blue, 2 red, 5 white........total of 10 sweaters
probability that red is picked first : 2/10 reduces to 1/5
replace
probability of second pick being white : 5/10 reduces to 1/2
replace
probability of third pick being blue : 3/10
probability of all of this happening : 1/5 * 1/2 * 3/10 = 3/100 <==
Unlikely because 2 girls over 7 children is less then 50%
The answer is -5.
Steps:
1. I multiplied the top equation by 2 and the bottom equation by 3 and then added them together.
2. 24x=72 is what you should have now. I divided each side by 24 to get x=3.
3. I plugged 3 in for x in one of the equations to get y=-8.
4. -8+3=-5.
