Answer:
D
Step-by-step explanation:
Multiply both sides by 12 to get x+36<_84.
Then move the constant to the right to get x by itself: x<_84-36
Subtract 36 from 84 to get 48.
Now you're left with x<_48
btw <_ is less than or greater than i just don't know how to place the sign on top of the underscore :/ hope this helped :)
You need to differentiate the equation to find the answer
Answer:
45/-3=-15
Step-by-step explanation:
A negative integer is a negative whole number that is the opposite of a counting number. It is simply an integer less than 0.
Answer: If he has 3 mystery books, and those are 1/8 of his whole collection, he has 24 books.
Step-by-step explanation:
3 = 1/8 × x
multiply both sides by the reciprocal of 1/8 which is 8/1 ("flipped fraction")
8 × 3 = 8/1(1/8) x <em>When you multiply a fraction by its reciprocal, it produces 1, so it "cancels" in the multiplication</em>
<em>24 = x </em>
<em>This may seem complicated, but understanding the process will help you solve more complicated questions like this in the future, I hope.</em>

Answer:
a = 4,
b = 12
c = 10
d = 15
Step-by-step explanation:
Since the product of each column is equal, therefore,
b*5 = 60
b = 60 ÷ 5 = 12
c*6 = 60
c = 60 ÷ 6 = 10
Since the sum of each column are equal, therefore,
12 + 10 + a = 5 + 6 + d
22 + a = 11 + d
Think of a number you can add to 22, and another number you can add to 11, which will make both sides equal. Add both numbers, whenmultiplied together should give you 60.
Factors of 60 are:
(a, d)
(1, 60) => 22 + a = 11 + d => 22+1 = 11+60 (incorrect)
(2, 30) => 22 + a = 11 + d => 22+2 = 11+30 (incorrect)
(3, 20) => 22 + a = 11 + d => 22+3 = 21+20 (incorrect)
(4, 15) => 22 + a = 11 + d => 22+4 = 11+15 => 26 = 26 [CORRECT]
(5, 12) => 22 + a = 11 + d => 22+5 = 11+12 (incorrect)
(6, 10) => 22 + a = 11 + d => 22+6 = 11+10 (incorrect)
Therefore,
a = 4,
d = 15
