Answer:

x=−27

Step-by-step explanation:

5(x+3)=4(x−3)

Step 1: Simplify both sides of the equation.

5(x+3)=4(x−3)

(5)(x)+(5)(3)=(4)(x)+(4)(−3)(Distribute)

5x+15=4x+−12

5x+15=4x−12

Step 2: Subtract 4x from both sides.

5x+15−4x=4x−12−4x

x+15=−12

Step 3: Subtract 15 from both sides.

x+15−15=−12−15

x=−27

Answer:

Step-by-step explanation:

Given

5(x + 3) = 4(x - 3) ← distribute both sides

5x + 15 = 4x - 12 ( subtract 4x from both sides )

x + 15 = - 12 ( subtract 15 from both sides )

x = - 27 → B

Margarita [4]

Answer:

5 + 3x = 41

x = 12 miles

Step-by-step explanation:

A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled.

Let x is the number of miles traveled.

If the total cost of the fare was $41.00 then

5 + 3x = 41 eq. 1

The above equation can be used to determine the number of miles traveled.

Solving the equation for x,

5 + 3x = 41

3x = 41 - 5

3x = 36

x = 36/3

x = 12 miles

Therefore, 12 is the total number of miles traveled if the fare was $41.00.

A manufacturer of a certain type of large machine wishes to buy rivets from one of two manufacturers. It is important that the b

Anvisha [2.4K]

Answer:

Not solvable.

Step-by-step explanation:

The normal way to answer this question would be to use the following formula formula for Standard Normal Distribution

$P(X) = P (\frac{X-u}{a})$

Where

$X$ = Minimum Breaking Strength = 10,000 psi

$u$ = Mean Breaking Strength = 14,000 psi / 13,000 psi

$a$ = Standard Deviation of each manufacturer

We put in the values, get the values of Z and use the Standard Normal Distribution Table to get the values for each manufacturer and compare. The manufacturer with the lower value will produce the lower amount of defective sprints.

Since standard deviation values are not given in this question we cannot solve this equation.
