Answer:

The combined like terms to create an equivalent expression 20(-1.5r+0.75) is -30r + 15.

Step-by-step explanation:

Consider the provided expression:

20(-1.5r+0.75)

Use the distributive property: a(b + c) = ab + bc

-30r + 15

After using distribution property there are no more like terms. Thus, -30r + 15 is the simplest form.

Hence, the combined like terms to create an equivalent expression 20(-1.5r+0.75) is -30r + 15.

(6+3)4 I don't understand what it means I really need some help​
Over [174]

Answer:

36

Step-by-step explanation:

Hullo :D

If you're having trouble understanding, you might not understand the Order of Operations.

P - Parenthesis. Solve what's inside the Parenthesis first

E - Exponents. Solve for Exponents second.

M - Multiply. Multiply numbers third. (left - to - right with division, too)

D - Divide. Divide fourth. It is interchangeable with multiplication, as well.

A - Addition. Add fifth.

S - Subtract sixth. It is interchangeable with Addition, as well.

With that in mind, all we need to do is identify these types in the equation:

(6+3)4

We see parenthesis. We will solve them first according to the Order of Operations:

6 + 3 = 9.

(9)4

We see multiplication. We solve them next according to the Order of Operations:

9 × 4 = 36.

Thus, the final answer is \boxed{36}.

Hope this helps!

Find the four arithmetic means between -21 and -36.
lara31 [8.8K]
The numbers given in the problem above are part of an arithmetic sequence with first and sixth terms equal to -21 and -36, respectively. Firstly, calculate for the common difference (d).
 
                                    d = (-36 - -21) / (6 - 1) = -3

The arithmetic mean is calculated by adding -3 to the term prior to it. 

            a2 = -21 + -3 = -24               a3 = -24 + -3 = -27
            a4 = -27 + -3 = -30               a5 = -30 + -3 = -33

Thus the four arithmetic means are -24, -27, -30, and -33.

professor190 [17]

Answer:

The fraction of smoothies sold were either banana or strawberry is  \frac{11}{12}.

Step-by-step explanation:

Given:

Of the smoothies sold yesterday at Marlins smoothie shop, 5/6 were banana and another 1/12 were strawberry.

Now, to find the fraction of the smoothies sold were either banana or strawberry.

Fraction of smoothie were of banana = \frac{5}{6} .

Fraction of smoothie were of strawberry = \frac{1}{12} .

Now, to get the fraction smoothies sold were either banana or strawberry by adding both the fractions of banana and strawberry:

\frac{5}{6} +\frac{1}{12} \\\\=\frac{10+1}{12} \\\\=\frac{11}{12}

Therefore, the fraction of smoothies sold were either banana or strawberry is  \frac{11}{12}.
