Answer:
B) 11.8
Step-by-step explanation:
First write in 4 for x and 2 for y
Then multiply 1.3 times 6 (4+2) and subtract 2-6
Your expression should now be 7.8 +4
After adding these, it should be 11.8
Hello from MrBillDoesMath!
Answer: infinite solutions
Discussion: I did a double take on this one but the left hand is
a + 3 + 2a = 3a +3
and the right hand side is
-1 + 3a + 4 = 3a + (4-1) = 3a + 3
The left and right sides of the equation are identical for all "a", i.e. for infinitely many "a" values.
Regards, MrB.
Answer:
as below
Step-by-step explanation:
1st the difference is 4 b/c half of 4 = 2
and
2*smaller +greater = 13
so check out small number that are 4 apart.. like 2 and 6
2(2)+6 =10
2(3) +7 = 13 aahh hah.. that's it
3 and 7 are the numbers being hunted :P
Answer:
Option 3: mean increases by 3
Step-by-step explanation:
Current mean:
[50+76+78+2(79)+80+81+2(82)+83] ÷ 10
= 77
Without the outliers:
[76+78+2(79)+80+81+2(82)+83] ÷ 9
= 80
80 - 77 = 3 (increase)
Since one package cost $24 and each person puts $6 .you then divide 24 divided by 6 then you get four people
