What is the cost of 4 pounds of butter if 2 kilograms cost $3.20

Answers

Answer 1

Answer:
In this modern space age in which we live, we'll need to be careful.

2 kilograms weighs 4.409 pounds on Earth. If that much
costs $3.20, then the cost for 4 pounds is

(4 / 4.09) x (3.20) = $2.90 .

But what if you grow up to live or work on the Moon ?

2 kilograms weighs only 0.73 pounds on the Moon. If that much
costs $3.20, then the cost for 4 pounds up there is

(4 / 0.73) x (3.20) = $17.54 .

The thing to remember is that if you make frequent trips between
the Earth and the Moon, make sure you buy stuff by mass, not by
weight. The weight changes when you take it somewhere else,
and you don't want to get cheated.

The quotient of 33/6,789

Answers

Answer:

The quotient of 33/6,789 is 0.0049.

Step-by-step explanation:

$(33)/(6,789)$

Reduce the given fraction into lowest form:

$(33)/(6,789)=(11)/(2,263)$

Now with help of long division method divide 11 by 2,263:

$(11)/(2,263)=0.0048608\approx 0.0049$

The quotient of 33/6,789 is 0.0049.

The quotient is an answer to a division problem, so basically you just have to do the fractional division indicated by the fraction itself. The fraction bar literally means "divided by"... so the fraction literally reads
33 divided by 6,789.

To divide, you have to add a decimal to 33 and then add some zero's until you have enough to do the math (33.00000). You can add as many zero's as you want and it doesn't change the value of 33.

Check the picture, I did the long division in case you don't know how.
I rounded the answer to the nearest ten thousandths place.

4(2+3c)=56 What would be the answer? Really Need Help On Sovling Multi-Step Equations

Answers

this should help you, Simplifying 4(2 + 3c) = 56(2 * 4 + 3c * 4) = 56(8 + 12c) = 56Solving8 + 12c = 56Solving for variable 'c'.Move all terms containing c to the left, all other terms to the right.Add '-8' to each side of the equation.8 + -8 + 12c = 56 + -8Combine like terms: 8 + -8 = 00 + 12c = 56 + -812c = 56 + -8Combine like terms: 56 + -8 = 4812c = 48Divide each side by '12'.c = 4Simplifyingc = 4

8 + 12C = 56

12C = 48

C = 4

Evaluate the expressions 3x-2 and 4x+4 for the following value of x.

Answers

Question:

Evaluate the expressions 3x - 2 and 4x + 4 for the following values of x. When you have found the value for each expression, write a statement using <, >, or = that shows how the two values are related. a. x = 0 b. x = -6 c. x = 5 d. x = -2

Answer:

Part a: $4x+4>3x-2$

Part b: $4x+4=3x-2$

Part c: $4x+4>3x-2$

Part d: $4x+4>3x-2$

Explanation:

Part a: Substituting $x=0$ , we get,

$\begin{aligned}3 x-2 &=3(0)-2 \n&=-2\end{aligned}$

$\begin{aligned}4 x+4 &=4(0)+4 \n&=4\end{aligned}$

The value of $3x-2$ is less than $4x+4$

Thus, $4x+4>3x-2$

Part b: Substituting $x=-6$ , we get,

$\begin{aligned}3 x-2 &=3(-6)-2 \n&=-18-2 \n&=-20\end{aligned}$

$\begin{aligned}4 x+4 &=4(-6)+4 \n&=-24+4 \n&=-20\end{aligned}$

The value of $3x-2$ and $4x+4$ are equal.

Thus, $4x+4=3x-2$

Part c: Substituting $x=5$ , we get,

$\begin{aligned}3 x-2 &=3(5)-2 \n&=15-2 \n&=13\end{aligned}$

$\begin{aligned}4 x+4 &=4(5)+4 \n&=20+4 \n&=24\end{aligned}$

The value of $3x-2$ is less than $4x+4$

Thus, $4x+4>3x-2$

Part d: Substituting $x=-2$ , we get,

$\begin{aligned}3 x-2 &=3(-2)-2 \n&=-6-2 \n&=-8\end{aligned}$

$\begin{aligned}4 x+4 &=4(-2)+4 \n&=-8+4 \n&=-4\end{aligned}$

The value of $3x-2$ is less than $4x+4$

Thus, $4x+4>3x-2$

Which expression is equivalent to 30(1/2x-2)+40(3/4y-4)?1.45xy-220
2.15x-30y-220
3.15x+30y-220
4.15x+30y-64

Answers

The expression is equivalent to the expression 30(1/2x - 2) + 40(3/4y - 4) will be 15x + 30y - 220. Then the correct option is C.

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expression is given below.

⇒ 30(1/2x - 2) + 40(3/4y - 4)

Simplify the expression, then we have

⇒ 30(1/2x - 2) + 40(3/4y - 4)

⇒ 15x - 60 + 30y - 160

⇒ 15x + 30y - 220

The expression is equivalent to the expression 30(1/2x - 2) + 40(3/4y - 4) will be 15x + 30y - 220. Then the correct option is C.
