The answer is 7.5
But u need 8 tables because you cant cut a table in half. The number facts that i used was 60 divided by 8.
PS. Please like this answer or i wont answer anymore of your questions
Answer:
i) x points; ii) 2x - 75 = -25; iii) x = 25
Step-by-step explanation:
i) Starting points
Let's say you had x points before doubling your score.
(ii) The equation
After doubling score: 2x points
After losing 75 points: (2x - 75) points
At end of game: -25 points
The equation is
2x - 75 = -25
iii) Solution to equation
2x - 75 = -25 Add 75 to each side
2x = 50 Divide each side by 2
x = 25
I would first add 5 and 2 together, then multiply that by 3. Finally you would subtract the 1. After solving for what is inside the parentheses you would multiply it by 2 for your final answer.
2•(3(5+2)-1)
2•(3(7)-1)
2•(21-1)
2•(20)
40
The topics you should learn are equating denominators and fractions. This is summing up simple fractions.
So we have to make denominators' numbers the same in order to sum up them all (we can sum fractions if the denominators are the same) , and we did it by cross product (that thing on the picture)
Equating by lcm (least common multiple) is the easiest way, because you might see bigger numbers on other questions, and cross product will bring much bigger numbers, so this technic might confuse you.
By the way lcm of 4 and 5 is already 20
Hope it helps!
Answer:

Step-by-step explanation:
We can divide polynomials by other polynomials by dividing each term by the denominator. Remember, when we divide a variable by itself, we must change the exponent in our answer according to exponent rules.
