Answer:
20
Step-by-step explanation:
This sequence follows a pattern of doubling then subtracting by two. The last action was 12 to 10, which is subtracting by two, so the next must be multiplying by 2.

Step-by-step explanation:
Let's solve your system by substitution.
2x−2y=−4;2x+y=11
Rewrite equations:
2x+y=11;2x−2y=−4
Step: Solve2x+y=11for y:
2x+y=11
2x+y+−2x=11+−2x(Add -2x to both sides)
y=−2x+11
Step: Substitute−2x+11foryin2x−2y=−4:
2x−2y=−4
2x−2(−2x+11)=−4
6x−22=−4(Simplify both sides of the equation)
6x−22+22=−4+22(Add 22 to both sides)
6x=18
6x/6 = 18/6
(Divide both sides by 6)
x=3
Step: Substitute3forxiny=−2x+11:
y=−2x+11
y=(−2)(3)+11
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5
Answer:
The fraction form of 33% is 1/3
Hi, first, the grammar has been a bit confusing, but i think i have it. the question is that one group has 28 baseball cards and another has 68, right? in order to tell how much each person could have received, we first have to know how many people there were and divide the numbers of cards by that. since you never specified the number of people in the groups, i can't solve it completely. all together you have 96 cards. i hope this helps.
