Answer:

x=21

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+5+5x+7=180

Step 1: Simplify both sides of the equation.

3x+5+5x+7=180

(3x+5x)+(5+7)=180(Combine Like Terms)

8x+12=180

Step 2: Subtract 12 from both sides.

8x+12−12=180−12

8x=168

Step 3: Divide both sides by 8.

8x /8 = 168 /8

x=21

Of the coffee makers sold in an appliance store, 4.0% have either a faulty switch or a defective cord, 2.5% have a faulty swi

lukranit [14]

Answer: Hence, Probability that a coffee maker will have a defective cord is 0.376=37.6%.

Step-by-step explanation:

Since we have given that

Let A be the event of getting a faulty switch.

Let B be the event of getting a defective cord.

Here, P(A∪B) = 4% = 0.04

P(A∩B) = 0.1% = 0.001

P(A) = 2.5% = 0.025

We need to find P(B):

As we know that

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\0.04=P(A)+0.025-0.001\\\\0.04=P(A)+0.024\\\\P(A)=0.04-0.024=0.376$

Hence, Probability that a coffee maker will have a defective cord is 0.376=37.6%.
