answer:
statements
1. <5 = <6
2. <4 + <5 = 180
3. <4 + <6 = 180
reasons
1. given
2. definition of linear pair
3. substitution
step-by-step explanation:
- i have written the statements and reasons seperately so just put them in the order i have
- in a proof we always put the given first
- now, we can see that <4 and <5 are "together" in a straight line, therefore they are linear pairs
- linear pairs add up to 180 (always)
- now that we have that, we can use susbtitution to get the answer want/prove what we want to prove
In expanded form, it would be 9*10 + 5*1 + 4 * 0.1 + 1 * 0.01 + 7 * 0.001. Hope this helps!
There are 10 marbles, out of these 10 there are 4.
The probability of her picking a blue marble is 4/10
This can be simplified to 2/5
X = 4
EXPLANATION:
45/60 can be simplified by dividing both 45 and 60 by the same number.
We already know the numerator is 3.
so we have to do the equation 45 divided by 3. which is 15.
so now we do 60 divided by 15 to find x.
So x = 4
