Jack said that if you take a number and multiply it by a fraction, the product will always be smaller than what you started with
ELEN [110]

Answer:

Is not correct. The product not always will be smaller.

Step-by-step explanation:

A fraction could increase a number if you multiply it.  

If the numerator is higher to the  denominator,  it will increase it.  

If the numerator is smaller to the  denominator,  it will decrease it.

<u>For example,</u>

10 x 4/3

For fraction multiplication, multiply the numerators and then multiply the denominators to get

10×4/1×3=40/3= 13,33

13,33 is higher than 10.

5 x 10/3

For fraction multiplication, multiply the numerators and then multiply the denominators to get

5×10/1×3=50/3

16,66 is higher than 5.

Write the equation in the standard linear equation form (Ax+By=C) if possible. Is the equation linear? y/3+x=5
mojhsa [17]

Answer:

3x + y = 15

Step-by-step explanation:

y/3 + x = 5

You can first move the x and y variable around so it fits the standard linear equation format.

x + y/3 = 5

In order to make it look more like the standard format, you can multiply both sides of the equation by 3 to get rid of the 3 in the denominator of the y variable.  It would look like this:

3 ( x +y/3) = 3 ( 5 )

When you multiply this out, you get this:

3x + y = 15

Use distributive property to remove parentheses -6(-5y+3x-2)
NISA [10]

Answer:

30y - 18x +12

Step-by-step explanation:

Distribute (multiply) -6 to all terms within the parenthesis. Remember to follow the sign rules: negative x negative = positive ;  negative x positive = negative

-6(-5y) = 30y

-6(3x) = -18x

-6(-2) = 12

Combine:

30y - 18x + 12 is your answer
