When is subtraction always the first operation done in an expression?

A Never
B When it follows addition in an expression.
C When it is the first operation in an expression, from left to right.
D When it is in parentheses in an expression.

Answer 2
C

The order of operations tells us the correct steps for solving a math problem.
PEMDAS
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtract
Subtraction is the last step, so if none of the 5 steps before it are in the equation, then that is when you will do subtraction first.

Answers

Answer:

Ok so I’m stuck with this question too But I got the top part.

p=1/6

q=2/6

r=3/6

s=3/6

A) The probabilities placed at P, Q, R and S on the tree diagram are;

P = 1/6; Q = 1/3; R = 1/4; S = 1/4

B) The probabilities of her winning or losing is;

Probability that she will win = 5/12

Probability that she will lose = 7/12

A) From the given tree diagram, we can see that;

At point P; Only 1 is rolled.

Since there are 6 possible numbers, then Probability at P = 1/6

At point Q; either 2 or 3 can be rolled.

Since there are 6 possible numbers, then Probability at Q = 2/6 = 1/3

At point R; 4,5, or 6 can be rolled on first roll.

Thus, Probability on first roll = 3/6

At R on second roll if she gets even, probability on second roll = 3/6

At S on second roll if she gets odd, probability on second roll = 3/6

Thus;

Overall probability at R = 3/6 × 3/6 = 1/4

Overall probability at S = 3/6 × 3/6 = 1/4

B) Probability that she will win are the probabilities at P and R.

Thus, probability that she will win = 1/6 + 1/4 = 5/12

Probability that she will lose are the probabilities at Q and S.

Probability that she will lose = 1/3 + 1/4 = 7/12

A. 2(3x + 12)
B. 28 + 4x – 4 + 2x
C. 5x + 7 + x + 17
D. 3(8 + 3x)

Answers

Answer:

D

the answer is D because when you multiply 3(8 + 3x), it will give you 24+9x

3(8 + 3x)  is not equivalent to 24 + 6x.

Option D expression is not equivalent to 24 + 6x.

What is an expression?

An expression or algebraic expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them.

According to the question

Expression is NOT equivalent to 24 + 6x

A . 2(3x + 12)

= 2(3x) + 2(12)

= 6x  + 24

= 24 + 6x

B. 28 + 4x – 4 + 2x

= (28 - 4) + (4x + 2x)

= 24 + 6x

C. 5x + 7 + x + 17

= (5x + x) + (7 + 17)

= 6x + 24

= 24 + 6x

D. 3(8 + 3x)

= 3(8x) + 3(3x)

= 24 + 9x

Hence, Option D is not equivalent to 24 + 6x.

3(8 + 3x)  is not equivalent to 24 + 6x.

Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 3.

Answers

Answer:

1 / 36

Step-by-step explanation:

A roll of 2 fair dice :

Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36

Probability = required outcome / Total possible outcomes

Required outcome = total less than 3 = 1 (from sample space provided)

Hence,

P(total less than 3) = 1/36

Solve for w. -34=-6+w/4

Answers

Answer:

w=−112

Step-by-step explanation:

-34=-6+w/4

Simplify both sides of the equation.

−34=−6+ w /4

−34=−6+ 1 /4 w

−34= 1 /4 w−6

Flip the equation.

1 4/ w−6=−34

Add 6 to both sides.

1 /4 w−6+6=−34+6

1 /4 w=−28

Multiply both sides by 4.

w=−112

Answer:

w = - 112

Step-by-step explanation:

-34=-6+w/4

1. Add 6 on both sides

-34 + 6 = -6 + 6 + w/4

-28 = w/4

2. Multiply 4 on both sides since it's the opposite of dividing

-28 * 4= w/4 * 4

- 112 = w

A rectangular water tank is 80 m long, 50 m wide and 60 m height. If the
depth of water in the tank is 45 m, find the volume of water required to
completely fill the tank?*

A)240,000cm3
B)60,000cm3
C)180,000cm3
D)120,000cm3

Answers

Answer: 2

Step-by-step explanation:

80 x 50 x 60 is volume of tank

240000

Water is already filled to 45 so volume up to that is

80x 50 x 45 = 180000

Subtract to find the difference needed to fill tank

240000 - 180000 = 60000

The volume of water to completely fill the tank is A) 240,000cm³.

What is volume?

Volume is defined as the amount of three-dimensional space occupied by some close object.

We know the volume of a cuboid is (Height×Width×Length).

Given a rectangular water tank is 80m long, 50m wide and 60m in height and the depth of the water is 45m.

To obtain the volume of water we have to take 45m as the height or we can think of the height of the tank is 60m but water can only be filled up to 45m.

∴ The volume of the water is (80×50×45) m³.

= 180,000 m³.

Answer:

200 minutes

Step-by-step explanation:

25 * 8 = 200

200 minutes

The rate will be 8.33 minutes per picture. Then the number of minutes will be 200 minutes.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Clayton draws 3 pictures in 25 minutes. Then the rate is given as,

Rate = 25 / 3

Rate = 8.33 minutes per picture

He drew 24 pictures this week. Then the number of minutes is calculated as,

⇒ 24 x 8.33

⇒ 200 minutes

The rate will be 8.33 minutes per picture. Then the number of minutes will be 200 minutes.
