Answer:</h2>
In this exercise we have the following pattern:
1, -12, 12, -1
So we need to find the rule for this patter. First of all, let's take the first number, which is 1:
1
To find the second number, which is -12, we must subtract 13, because:
1 - 13 = -12
To find the third number, which is 12, we must add 24, because:
-12 + 24 = 12
In conclusion, the correct answer is A.) subtract 13, then add 24
Answer:
the answer is twenty four
To solve, you need to find the least common multiple of the denominator.
In this case, its 30.
3*9= 27/30
1*10 = 10/30
She walked 37/30 miles or 1 mile and 7/30th of a mile
Answer:
b. 4x^2 -7x +5
Step-by-step explanation:
When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...
(7x^2 -5x +4) - (3x^2 +2x -1)
= (7 -3)x^2 +(-5 -2)x +(4 -(-1))
= 4x^2 -7x +5 . . . . . matches B
Answer:
x = 5. y = 4
Step-by-step explanation:
7x - 4 = 31
7x = 35
x = 5
4y + 8 = 24
4y = 16
y = 4
