Answer:7
Step-by-step explanation:
8+4=12
2(x-1)= 2x-2
12=2x-2
now add 2 to both sides
14=2x
And divide both sides by 2
7=x
5.82% = 0.0582 in decimal form.
If u multiply the first equation by -4, u get -2x - y = -20
and when u add the 2 equations..
-2x - y = -20
2x + 3/8y = 5
-----------------
0 - 5/8y = -15.....u notice that the x terms r eliminated.
2/3 of 18...." of " means multiply
2/3 * 18 = 36/3 = 12....she has memorized 12 words so far
Not much of an expert... Pretty sure it's something like this...
(5x100) + (5x90) + (5x8)
Then you solve the brackets...
500 + 450 +40
Then you add it all together...
=990
