14 x 4 = 56
Jonia needs 56 tablets to fill Mr. Robinson’s prescription.
5(a - 2b) - 3(a - 2b) |use distributive property: a(b - c) = ab - ac
= 5a - 10b - 3a + 6b
= (5a - 3a) + (-10b + 6b)
= 2a - 4b

Step-by-step explanation:
First, you need to multiply 3x5 and Sunday you 2B-3B. Now the problem is 18-15+-1. Since there is no exponents, multiplication, or division in this problem anymore, we are going to add. 15+-1=0. Now we have 18-0. 18-0=18. Therefore the answer is 18
First, I would create a number line that includes the number -4 to 4, with 1/4 notches (3 notches between each number).
For 3, I would count 3 numbers to the right from zero.
For 2.25, I would count 2 numbers from zero, plus one additional notch to the right. Remember that each notch represents 1/4, or 0.25.
For the opposite of 4, I would count 4 to the left to -4. The opposite of 4 is -4.
For -(-1 1/2), I would remember that this number is actually 1 1/2, since a negative times a negative number is positive. I would count one number to the right of zero, plus two notches.
