Apply the distributive property to create an equivalent expression.
−9⋅(5j+k)=

Answers

Answer 1
Answer:

Multiply the number outside the parenthesis by each term inside the parenthesis:

-9 * 5j = -45j

-9 *k = -9k

−9⋅(5j+k) = -45j - 9k
Answer 2
Answer:

Answer:

-45j-9k.

Step-by-step explanation:

The given expression is

-9\cdot (5j+k)

We need to find the equivalent expression of given expression.

According to the distributive property,

a(b+c)=ab+ac

Using distributive property the given expression can be rewritten as

-9\cdot (5j)-9\cdot (k)

-45j-9k

Therefore, the required expression is -45j-9k.

The number of tomato plants (t) is twice the number of pepper plant (p) A. t=2+p
B. +t=p
C.2t=p
D. t=2p

Answers

the number of tomato plants (t) is (=) twice (2 times) the number of pepper plants (p)
t=2(p)

so the anser is t=2p or D
D. T=2p

This is because the number of tomato plants (t) is (=) twice (2) the number of pepper plants (p)

9/2 as a mixed number

Answers

In order to make (9)/(2) a mixed number you have to do division. (9)/(2)=4 (1)/(2). Check:4 (1)/(2)= (4*2+1)/(2)= (9)/(2). Therefore, (9)/(2) as a mixed number is \boxed{4 (1)/(2)}. Hoped I helped. :)
To find a mixed number, you can see that 2/2 can stand for one. So you find out, how many 2/2s are in 9/2. The answer is 4 but then you still have 1/2 left. So you end up with 4.5 or 4 1/2

What does 8(x-3) equal?

Answers

8 ( x - 3 ) = *8x + -24* or *8x - 24* (theyre the same thing) what You do is just distribute the 8 to ALL numbers inside parantheses. Hence, 8 times x is *8x* and 8 times a negative -3 is *-24*. Hope i helped!
