Answer:
She type <u>75 words</u> in 1 minute.
Step-by-step explanation:
Given:
Lolo typed 1,125 words in 15 minutes.
Let w represent the number of words typed each minute.
Now, to find the number of words she type in 1 minute if Lolo typed the same number of words each minute.
So, we solve it by using cross multiplication method:
<u><em>As 1125 words is equivalent to 15 minutes.</em></u>
<u><em>Thus, w number of words equivalent to 1 minutes</em></u>.
By cross multiplying we get:
⇒ 
<em>Dividing both sides by 15 we get:</em>
⇒ 
⇒ 
Therefore, she type 75 words in 1 minute.
Answer:
Simplest form = 4<em>z </em>+ 21
Case 1: True, Case II: false and Case III: true
Step-by-step explanation:
18<em>z </em>- 7( -3 + 2z)
= 18<em>z</em> + 21 - 14z
= 18<em>z</em> -14z + 21
= 4<em>z </em>+ 21
So, in the above expression we have two terms. First term is 4z and second term is 21.
So the first case is true. As the expression has two terms.
The coefficient of <em>z </em>is a number which is multiplied by <em>z</em>. Therefore, Second case is false as the coefficient of <em>z</em> is 4.
The constant is a number which is not multiplied by any variable. Therefore, third case is true as the constant number in above expression is 21.
Answer:is 30
Step-by-step explanation:
So u can say 5+5=10, well if the answer is 10 then 10+10= 20 and then if u add 10 to 20 you will get 30
you can used the give answer app and will tell you everything
The opposite of multiplication is division, so if you take the signaler number after the equal sign divide it by the number before and it will give you the missing number like this:
(I'm only going to do a few and then you try it. I can check it when you are done)
6 x ____ = 60 <<<Divide 6 by this number
60 ÷ 6 = 10
6 x 10 = 60
140 ÷ 10 = 14
140 = 14 x 10
500 ÷ 50 = 10
50 x 10 = 500
Hope this helps!
