Answer:
x = -1
Step-by-step explanation:
AB + BC = AC = 28
the way from A to C goes through B.
so, the total way of A to C is the sum of the way from A to B and then from B to C.
=>
(5x + 10) + (2x + 25) = 28
7x + 35 = 28
7x = -7
x = -1
Answer:
B
Step-by-Step Explanation:
if you do a <u>Percent Proportion</u> you will get:
_1__ = _0.1_ 0.1x10=1
1000 100
Use distributive property: multiply the number outside the bracket by each number inside it
1. 14x+21=35 14x=14 x=1
2. -32x-24=40 -32x=64 x= -2
3. 16-10x=-44 -10x=-60 x=6
An = a1 + (n-1)d
an = 27 + (n-1)(-6)
