Expand and simplify each of the following expressions.
(a) 5(a + 2b) – 36
(b) 7(p + 10q) + 2(6 + 79)
(c) a + 3b – (5a – 4b)
(d) x + 3(2x – 3y + z) + 7z

A:5a+10b−36

B:7p+70q+17

C:−4a+7b

D:7x−9y+10z

Step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
