<u>Given:</u>
The two equations are 
and 
We need to solve the equations using elimination method.
<u>Elimination method:</u>
Let us multiply the equation by 5, we get;
---------(1)
Now, multiplying the equation by -2, we get;
--------(2)
Adding equations (1) and (2), we have;
Thus, the value of y is 3.
Substituting in the equation , we have;
Thus, the value of x is 4.
Hence, the solution of the system of equations is (4,3)
Therefore, Option A is the correct answer.
Assume Alan's brother has x coins before Alan gave him 48 coins
x+48=1.4x (increased by 40%)
0.4x=48
x=120
120+140=260
answer is 260 coins
Hello from MrBillDoesMath!
Answer:
The correct answer is p >= -5/3
but I don't see that answer as a provided choice (?)
Discussion:
Solve:
2(6p-5) >= 3(p-8) - 1 =>
2*6p - 2*5 >= 3*p - 3*8 -1 =>
12p -10 >= 3p - 24 - 1 => (subtract 3p from both sides)
12p-3p - 10 >= -25 => (add 10 to both sides)
9p >= -25 + 10 = -15 =>
p >= -15/9 = -5/3

MrB
Correct answer: the first choice !
So allison spent 3/5 meaning she saved 2/5 because 3/5 + 2/5 = 5/5
change the 2/5 into decimals by 2 ÷ 5 = 0.4
multiply $55 with 0.4
55 x 0.4 = 22
so she ends up saving $22
