Answer:

Step-by-step explanation:
Negative numbers are "smaller" than positive numbers. Just arrange them.
2500/5=500 this is the unit rate
Answer:
2(a+3b)-(b+c)=
2(4+3(2))-(2+3)=
2(4+6)-(5)=
2(10)-5=
20-5=
15
Step-by-step explanation:
1/16 You need to multiply 2x2x2x2 since all the coins are both two sided
Answer:
x=1.816298 or x=−1.162524
Step-by-step explanation:
Step 1: Multiply both sides by x^2.
x2=x4−3x3+8x2−16
x2−(x4−3x3+8x2−16)=x4−3x3+8x2−16−(x4−3x3+8x2−16)(Subtract x^4-3x^3+8x^2-16 from both sides)
−x4+3x3−7x2+16=0
(Use quartic formula)
x=−1.162524,1.816298
Check answers. (Plug them in to make sure they work.)
x=1.816298(Works in original equation)
x=−1.162524(Works in original equation)
