Translate the sentence into an inequality.
Twice the difference of a number and 3 is at least -20.

Answers

Answer 1

Answer: 2n-3>=-20

Step-by-step explanation: instead of the equal sign put a line under the sign <

Answer 2

After translating the given statement, the inequality will be 2x - 3 ≥ -20.

What is inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values.

Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the information in the question,

The statement for the inequality in the question,

Twice, the difference between a number and 3 is at least -20.

Let the number be x.

Twice the number is 2x.

So,

2x - 3 ≥ -20

Answers

Answer:

40 did it on edge

Step-by-step explanation:

The unit rate of calories per ounce will be 40 calories/ ounce

What is proportion ?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are given that 4-ounce container of Greek yogurt contains 160 calories and it is to calculate for one ounce calories contain in Greek yogurt :

4-ounce = 160

1- ounce = 160/4

=40

Therefore, the unit rate of calories per ounce = 40 calories/ ounce.

2 Truths & One Lie

- 39 - b = - 3

1. The Variable is B in this Equation
2. b = -36
3. b = 36

Which one is a Lie?

Justify your decision.

WILL GIVE 20 POINTS!!

Answers

Answer:

b = 36 is the lie.

Step by step:

If we plug in b with it equaling -36 the equation will be

-39 - (-36) which you remove the minus from the -36 and change the subtraction to addition and you get

-39 + 36 = -3

In the end b = -3

So the other one must be wrong, but just incase we will plug it in.

-36 - 36 = 0

Plugging in 36 for b results in 0 which is not correct.

If c – a = b, then true statement is A. a + b = c

What is commutative property?

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.

Now the given statement is,

c – a = b

adding a to both the the side

c – a + a = b + a

⇒ c = b + a

Using commutative property of addition we get,

a + b = b + a

Therefore, we get

⇒ c = a + b

Thus the true statement is A. a + b = c

For each question, draw a figure. Label the information on the figure. Write an equation that solves the
problem. Find the two answers requested. On AC, B is between A and C. For each question, find x and AB.
10. AB = 2x + 5, AC= 10x + 2. BC= 4x + 9.
11. AB = 3x, BC =x-6, AC = 8x - 14

Answers

Answer:

See attachment for the figures drawn for each question.

10. x = 3; AB = 11

11. x = 2; AB = 6

Step-by-step explanation:

10. AC = 10x + 2

AB = 2x + 5

BC = 4x + 9

AB + BC = AC (segment addition postulate)

(2x + 5) + (4x + 9) = 10x + 2 (substitution)

The equation above is what we would use to solve the problem as follows:

2x + 5 + 4x + 9 = 10x + 2

Combine like terms

6x + 14 = 10x + 2

6x - 10x = -14 + 2

-4x = -12

Divide both sides by -4

x = 3

AB = 2x + 5

Plug in the value of x

AB = 2(3) + 5 = 6 + 5

AB = 11

11. AB = 3x

BC = x - 6

AC = 8x - 14

AB + BC = AC (segment addition theorem)

3x + (x - 6) = 8x - 14 (substitution)

Use the equation to solve for x as follows:

3x + x - 6 = 8x - 14

Collect like terms

4x - 6 = 8x - 14

4x - 8x = 6 - 14

-4x = -8

x = 2 (dividing both sides by -4)

AB = 3x

AB = 3(2)

AB = 6
