Answer:
Hey there!
There are 13 clubs in a deck of cards.
There are 4 tens.
However, the tens overlap with the clubs, so there are 16 cards to choose.
16/52=4/13
Let me know if this helps :)
Answer:
c
Step-by-step explanation:
4 times 2 is 8. 3 and 3 times -4 is -12
8 minus -12 is negative 4
<u>Compound inequality:</u>
A compound inequality contains two or more inequalities that are separated either by "and" or "or".
And: It indicates that both statements of the compound sentence satisfies at the same time.
Or: This indicates that as long as either statement is true, the entire compound sentence is true.
For example:
1.
Here, and denotes that intersection or the overlap will be the desired result.
2.
Since the joining conjunction is or we can come to a point that the entire compound sentence is true.
AND CASES:
A number is a solution to the compound inequality if the number is a solution to both inequalities. It can either be written as x > -1 and x < 1 or as -1 < x < 1.
OR CASES:
A number is a solution to the compound inequality if the number is a solution to at least one of the inequalities. It is written as x < -1 or x > 1.
Answer:
x = 7, y = 2
Step-by-step explanation:
x= 4y -1
since x is by itself 4y-1 will substitute for x in the other equation x+2y=11
it will become 4y-1+2y=11
+1 +1
add one to both sides since is doesn't have a variable.
it will become 4y+2y= 12 now add 4y+2y
becomes 6y=12
_ _
6 6
divide by 6 on each side and you get y=2.
now x=4(2)-1 you will substitute y into the first equation.
x=8-1 subtract 8 from 1 to get 7.
x=7
y=2
