1/10(x + 11) = -2(8 -x)
please show your steps, will give brainliest.

Answers

Answer:

X = 1.9

Step-by-step explanation:

Distribute first!

1/10(x + 11) = -2(8 - x)

1/10x + 11 = -16 - (-x)

Then simplify (if need be):

1/10x + 11 = -16 + x

Combine like terms:

11 + 16 = 1x - 1/10x

27 = .9x

Divide to get your x by itself:

27/.9 = .9x/.9

27/.9 = x

Solve:

X = 30

Answer:

-149/9=x

Step-by-step explanation:

Use distributive property first

1/10x +11/10= -16 +x

move x's to one side and the constants to the other

11/10= -16 +x -1/10x

11/10 -16= 9/10x

simplify the constants

-16x10/10= -160/10 + 11/10= -149/10

-149/10=9/10x

multiply by reciprocal

-1490/90=x

simplify

-149/9=x

An art club sells 42 large candles and 56 small candles.
a. Write and simplify an expression that represents the profit.
expression for the profit: _(_-x)+_(_-y)
simplified expression for the profit: _______
b. A large candle costs $5, and a small candle costs $3. What is the club’s profit?
club's profit: $__

Answers

Answer:

Profit = $(700 - 42x - 56y)

Step-by-step explanation:

For large candles, the selling price is $10 and its making cost is $x.

So, by selling a large candle the profit is $(10 - x)

Again for small candles, the selling price is $5 and its making cost is $y.

So, by selling a small candle the profit is $(5 - y)

Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)

⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}

⇒ P = $(700 - 42x - 56y) (Answer)

A carton of two dozen eggs includes three with cracks. How many eggs without cracks can be expected in six dozen eggs?

Answers

Answer:

Step-by-step explanation:

because 2 dozens is 24, and since there are three cracked eggs in two dozens, in six dozens, which is 72 eggs, since 24 times 3 is 72, we have to multiply 3 times 3, which is nine, so 9-72,which is 73.

The number of eggs without cracks can be expected in six dozen eggs will be 63.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A carton of two dozen eggs includes three with cracks.

Crack egg = 3 / (12 x 2)

Crack egg = 3 / 24

Crack egg = 1/8

The number of non-crack eggs is given as,

Non-crack egg = (24 - 3) / 24

Non-crack egg = 7/8

Then the total number of eggs in six dozen is given as,

Total egg = 12 x 6

Total egg = 72

Then the total number of non-crack eggs is given as,

Total non-crack eggs = 72 x 7 / 8

Total non-crack eggs = 63

The number of eggs without cracks can be expected in six dozen eggs will be 63.

Television sizes are determined by the length of their diagonal measure. Michael just bought a new television. The height of the television is 37 inches and the length is 71 inches.

Using the Pythagorean Theorem, what is the size of Michael’s new television? Round your answer to the nearest whole inch (whole number).

Part A: What parts of the right triangle have you been given? Are you looking for a leg or the hypotenuse?

Part B: Set-up your equation by substituting the correct numbers into the Pythagorean Theorem formula.

Part C: Solve for the missing length rounded to the nearest whole number. Remember to show ALL work for each step.

Part D: What is the size of the television rounded to the nearest whole inch (whole number)? REMEMBER: We’re looking for the length of the diagonal, as that is the measurement used to determine TV Sizes.

Answers

Answer:

Part A we are given the legs and are looking for the hypotenuse

Part B 37^2 + 71^2 = c^2

Part C 37^2 + 71^2 = c^2

961+5041 = c^2

6002 = c^2

Take the square root of each side

sqrt(6002) = sqrt(c^2)

77.47257579=c

c = 77

Part D The size is 77 inches

Step-by-step explanation:

The pythagorean theorem is a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

a = 37 and b = 71 were are looking for the diagonal ( or hypotenuse) which is the size

37^2 + 71^2 = c^2

961+5041 = c^2

6002 = c^2

Take the square root of each side

sqrt(6002) = sqrt(c^2)

77.47257579=c

Rounded to the nearest whole number

77 =c

The size is 77 inches

There are 213 calories in three ounces of a certain ice cream. How many calories are there in one pound?
1 pound = 16 ounces
Before you try that problem, answer the question below.
How many ounces will you need to find the number of calories for? ( don;t forget Convert the given number of pounds to ounces)

Answers

Answer:

1. considering that there are 16 ounces in one pound, and the question is asking for one pound, I would think that there would only need to be 16 ounces observed.

2. Through calculations of the given number of oz, there are 71 calories per oz. By multiplying that by 16 (the number of oz in a lb) there are a total of 1,136 calories in a lb.

I believe the answer is 1,163 calories, I could be totally wrong..
