<span> the next three terms are : 8×(-1/2) ;(-4)×(-1/2) ;2×(-1/2)
</span>-4 ; 2 ; -1
Answer:
45 pound plate = 4
10 pound plate = 8
Step-by-step explanation:
x = 45 pound plate
y = 10 pound plate
x + y = 12 - - - (1)
45x + 10y = 260 - - (2)
x = 12 - y
45(12 - y) + 10y = 260
540 - 45y + 10y = 260
540 - 35y = 260
-35y = 260 - 540
-35y = - 280
y = 280 / 35
y = 8
x = 12 - y
x = 12 - 8
x = 4
Whenever you multiply or divide a negative number to both sides, you flip the sign
ex.
if you have x>1, and multiply -1 to both sides, then -x <-1
in your case, the best way to remove the -2 from the denominator would be to multiply -2 to both sides. Since you multiplied by a negative number, you need to switch the sign from < to >
Answer:
x=4 and x=-3
Step-by-step explanation:
You have to set each one equal to zero and solve for x
x-4=0 x+3=0
+4 +4 -3 -3
x=4 x=-3
