Which expression is equivalent to the expression shown?
4(-9 + (-3) + 8)

A
4(12 + 8)

B
4(-9) + 4(3 + 8)

C
4(1) + 4(-3)

D
4(-9) + 4(5)

Answers

The answer would be D.

The equivalent expression is 4(-9)+4(5), so option D is correct.

Equivalent expression:

Important information:

The given expression is [tex]4(-9+(-3)+8)[/tex].

The given expression can be written as:

[tex]=4(-9+(-3+8))[/tex]

[tex]=4(-9+5)[/tex]

[tex]=4(-9)+4(5)[/tex]

So, option D is correct.

The value of the given expression is:

[tex]4(-9+(-3)+8)=4(-4)[/tex]

[tex]4(-9+(-3)+8)=-16[/tex]

The value of other expressions are:

[tex]4(12+8)=80\neq -16[/tex]

[tex]4(-9)+4(3+8)=8\neq -16[/tex]

[tex]4(1)+4(-3)=-8\neq -16[/tex]

[tex]4(-9)+4(5)=-16[/tex]

It means options A, B and C are incorrect.

Therefore, the equivalent expression is 4(-9)+4(5), so option D is correct.

The coffee cup can hold 7/9 of a pint of liquid. If Emily pours 2/3 of a pint of coffee into a cup, how much more milk can she add?

Answers

1/9 pints of milk can be added by a customer

Step-by-step explanation:

We have to subtract simple fractions to find the amount of milk that can be added to a cup of coffee

Given

Total Capacity of a cup = 7/9 pints

Coffee to be added in a cup = 2/3 pints

So in order to find the amount of milk that can be added we have to subtract the amount of coffee from the total capacity of cup.

So,

Hence,

1/9 pints of milk can be added by a customer

Answers

Answer:

-42/4 or -10 1/2

Step-by-step explanation:

So you might want to convert the mixed numbers to improper fractions.

15/4*(-14/5)

Then what you want to do is cross multiply.

Since 5 can go into 15 that would make it into..

3/4*(14/1)

which makes it way easier to multiply.

3*(-14)= -42

4*(-1)= -4

your answer would be

-42/4 or -10 1/2

Explain why constant terms expressed as different rational number types can be combined.

Answers

Answer:

Constants, as the name suggest, stay constant, meaning that their value never changes. For example, 2 will always be 2 and 9.4 will always be 9.4. On the other hand, the values of variables can change. Take, for example, the variable 2x. When x = 1, 2x = 2 and when x =2, 2x = 4 so the value of 2x can change depending on what x is. You can't combine constants and variables because they are not like terms, basically, one can change and the other can't and you cannot combine terms that are not like each other.

Find the area of the triangle, since the top of the shape is 13m then the bottom is also 13m.

4+4=8

So the base of the triangle cutout is 5m

Now find the area of the triangle. The formula for this is:

A=1/2 * base/height

A=1/2 * 5/6
