8x+3-10x=2(x-2)+3

Answers

Answer 1

Answer:

x = 1

Step-by-step explanation:

8x + 3 - 10x = 2(x - 2) + 3

Distribute the 2

8x + 3 - 10x = 2x - 4 + 3

Combine like terms

-2x + 3 = 2x - 1

Add 1 to both sides

-2x + 4 = 2x

Add 2x to both sides

4 = 4x

Divide both sides by 4

x = 1

Equation: 5 + 8x < 3(2x + 4)


• So let’s first distribute:

Multiply 3 by (2x + 4)

That will be 6x + 12.


Put into the question: 5 + 8x < 6x + 12


• Now we can move the numbers around and UNDO to solve for x.

I will move the coefficient first, so subtract 6x from both side, so that it is easier:

5 + 8x < 6x + 12
- 6x < - 6x

That will be: 5 + 2x < 12


Now we’ll subtract the 5 from both side:

5 + 2x < 12
- 5 < -5

That will left with: 2x < 7


Now we divide both side by 2 to left with x.

2x < 7
—- —-
2 2

Now that will be: x is less than 3.5

x < 3.5


Since the inequality is open, the dot is white, or not shaded.

And since x is less than 3.5, any number less than 3.5 is the answer, so A is the answer.

Car repairs: Let be the event that a new car requires engine work under warranty and let be the event that the car requires transmission work under warranty. Suppose that ,P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .
(a) Find the probability that the car needs work on either the engine, the transmission, or both.
(b) Find the probability that the car needs no work on the engine.

Answers

Answer:

a) 0.11 =  11% probability that the car needs work on either the engine, the transmission, or both.

b) 0.9 = 90% probability that the car needs no work on the engine.

Step-by-step explanation:

P(E) = 0.10 , P(T) = 0.02 and P(E,T) = 0.01 .

This means that:

Only engine: 0.1 - 0.01 = 0.09

Only transmission: 0.02 - 0.01 = 0.01

Both engine and transmission: 0.01

(a) Find the probability that the car needs work on either the engine, the transmission, or both.

0.09 + 0.01 + 0.01 = 0.11

0.11 =  11% probability that the car needs work on either the engine, the transmission, or both.

(b) Find the probability that the car needs no work on the engine.

Probability of needing work on engine:

0.09 + 0.01 = 0.1

Not needing:

1 - 0.1 = 0.9

0.9 = 90% probability that the car needs no work on the engine.

Answers

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Andy works at a grocery store. The manager of the store would like Andy to set up a display of apples. Part of the display will include bags of apples. If there are 39 pounds of apples in the back of the store, how many bags of apples can Andy make for the display?

Answers

Answer:
Andy can make 26 bags for the display.

Step-by-step explanation:
Quantity of apples in the back of the store = 39 pounds
Quantity of apples in one bag = pounds
Here,

Number of bags = Quantity of apples in the back of the store / Quantity of apples in one bag

So, Andy can make 26 bags for the display of apples.

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 4500 × 0.04 × 2 = 360

I = $ 360.00

The simple interest accumulated

on a principal of $ 4,500.00

at a rate of 4% per year

for 2 years is $ 360.00.

Answer:

2250

Step-by-step explanation:

you times 4500 with 2 and get 9000. Then, you take the 9000 and divide it by 4 and get 2250.
