#5: cost: y
Number of beads: x
y=0.48*x
So for 4 beads: 1.92
for 5 beads: 2.4
#6: the x th term in the sequence is y
y=17-2x
The 10th term is -3
Answer:
Let's solve your equation step-by-step.
−3.1x+7−7.4x=1.5x−6(x−

)
Step 1: Simplify both sides of the equation.
−3.1x+7−7.4x=1.5x−6(x−

)
−3.1x+7+−7.4x=1.5x+(−6)(x)+(−6)(

)(Distribute)
−3.1x+7+−7.4x=1.5x+−6x+9
(−3.1x+−7.4x)+(7)=(1.5x+−6x)+(9)(Combine Like Terms)
−10.5x+7=−4.5x+9
−10.5x+7=−4.5x+9
Step 2: Add 4.5x to both sides.
−10.5x+7+4.5x=−4.5x+9+4.5x
−6x+7=9
Step 3: Subtract 7 from both sides.
−6x+7−7=9−7
−6x=2
Step 4: Divide both sides by -6.
−6x. /−6
