Answer:

Decimal form: 1.6

Fraction Form: 1    6/10

Step-by-step explanation:

The denominators are 2, 3, and 4.  The least common denominator is the least common multiple (LCM) of these numbers.

To find the LCM, first write the prime factorizations.

2 = 2¹

3 = 3¹

4 = 2²

The LCM is therefore 2² × 3 = 12.

Rewrite the fractions with a denominator of 12.

⁷/₄ + ¹/₂ + ⁵/₃ + ¹/₃ + ¹/₄ + ¹/₂

= ²¹/₁₂ + ⁶/₁₂ + ²⁰/₁₂ + ⁴/₁₂ + ³/₁₂ + ⁶/₁₂

Now that the denominators are the same, we can simply add the numerators.

= ⁽²¹⁺⁶⁺²⁰⁺⁴⁺³⁺⁶⁾/₁₂

= ⁶⁰/₁₂

= 5

Answer:

y = x - 5 :)

Step-by-step explanation:

use point-slope form to create an equation for this line.

find the slope first by subtracting the y-values from each other, and the x-values from each other.

-3-(-8) = 5                       <- y-value

2-(-3) = 5                        <- x-value

5/5 = 1                            <- slope

plug the slope and one of the points into the point-slope equation.

y - (-3) = 1(x - 2)

y + 3 = x - 2

subtract 3 from both sides.

y = x - 5

graph this by placing a point on -5 on the y-axis, and going up by 1 and right by 1 for the slope of 1.

Step-by-step explanation:

Hey there!

The line passes through points; (-3,-8) and (2,-3).

Now; use formula for double point.

[tex](y - y1) = \frac{y2 - y2}{x2 - x1} (x - x1)[/tex]

Put all values.

[tex](y + 8) = \frac{ - 3 + 8}{2 + 3} (x + 3)[/tex]

Simplify it.

[tex](y + 8) = \frac{5}{5} (x + 3)[/tex]

[tex]y = x + 3 - 8[/tex]

[tex]y = x - 5[/tex]

Therefore, the equation is y= x-5.

Fraction: y= 3/2x-3

or

Decimal: y= 1.5x-3

Step-by-step explanation:

Turn 3x-2y=4 into y=mx+b form

Subtract 3x from both sides

-2y=4-3x

Divide -2 from both sides

y= -2+3/2x

y= 3/2x-2

Since the line is parallel, use slope 3/2

Put point (6,6) into equation to find b

6=3/2(6) + b

y= 3/2x-3

Answer:

Step-by-step explanation:

y= 3/2x-3

Answer:

x = (d + b/c)/a

or x = d/a + ba/c

Step-by-step explanation:

1. ax - b/c = d

2. ax = d + b/c

3. x = (d + b/c)/a  (can also be written as x = (d + b/c)*1/a)

4. x = d/a + ba/c

Step 1 is given.

In step 2, b/c was added to both sides of the equation. This works because division is ahead of subtraction in the order of operations.

In step 3, both sides were divided by a.

(optional) In step 4, 1/a was multiplied by the values inside the parenthesis as a means to further simplify the equation.

Answer:

r i r

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

First, distribute. 12r + 16 = -16r - 40

Then get r on one side by adding 16r to both sides then subtracting 16 from both sides.                  28r = -56

Finally, divide by 28 on both sides to get r by itself.

r = -2

Answer:

170

Step-by-step explanation:

Ann, Ben, and Cindy were eating strawberries.

The ratio of the numbers of berries they ate is 5:5:7.

If Cindy ate 30 strawberries less than Ann and Ben together,

find:

what is the total number of strawberries the three of them ate?

solution:

add the ratios 5 + 5 + 7 = 17

since Cindy ate 30, less than Ann and Ben together so, the equation is

7x = 5x + 5x - 30

7x - 10x = -30

x = 30/3

x = 10

ann 5 x 10 = 50

ben 5 x 10 = 50

cindy 7 x 10 = 70  

total            = 170

Answer:

x ≈ 39.8

Step-by-step explanation:

cos∅ = adjacent / hypotenuse

Since we are given a right triangle, we can use trigonometry to help us solve for missing values:

cos34° = x/48

x = 48cos34°

x = 39.7938

x ≈ 39.8

Answer:

170

Step-by-step explanation:

You have to multiply the amount of ounces you want converted by 28.35. Then you have your ounces converted to grams.

If you use this formula then you would have, 170 X 28.35 = 170.1

When you round 170.1 to the nearest whole number you will get 170.

The conversion of 6 ounces into grams is 170 grams.

Multiplication or division by a numerical factor, selection of the correct number.

Multiply the number of ounces you want to be converted by 28.35. Use the conversion.

1 ounces = 28 .35 grams

6 ounces = 6 x 28.35 grams

6 ounces = 170 grams.

Hence, 6 ounces is equal to 170 grams.

Step-by-step explanation:

When combining like terms with exponents, you just add them together as long as they have the same exponent. 3x^3 + 2x^3 = 5x^3

9z+5z=14z

6x^2 has no like terms.

Using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

The law of Syllogism is a method of deductive reasoning which involves drawing a conclusion from two premises.

Applying this law, there are usually three statements.

Statement 1: If a, then b (premise)

Statement 2: If b then c (premise)

Statement 3: If a, the c (conclusion)

In the question above, in the same vein, from the first and second statement, we can conclude that:

If a figure is a square, then it is not a triangle, because a square has 4 sides and a triangle doesn't.

Therefore, using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.
