lox (x) = -5
rewrite the equation in exponential form:
10^-5 = x
10^-5 = 1/10000
1/10000 = 0.00001
That is the correct answer.
The answer is 8/10 and that simplified is 4/5
An orange ... o grams = ?
a pineapple ... p = 7 * o
p = 870 grams + o
If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:
7 * o = 870 + o
7 * o - o = 870
6 * o = 870 /6
o = 870 / 6
o = 145 grams
p = 7 * o = 7 * 145 grams = 1015 grams
Result: A pineapple weights 1015 grams and an orange 145 grams.
Answer:
C. I & III
Step-by-step explanation:
I simplifies to ...
2(6x +15 -5x) +4 = 40
12x +30 -10x +4 = 40
2x +34 = 40
__
II simplifies to ...
40 = 2(15 -x) +4
40 = 30 -2x +4
40 = -2x +34 . . . . . . not equivalent to I (sign of x-term is different)
__
III simplifies to ...
12x +30 -10x +4 = 40
2x +34 = 40 . . . . . . equivalent to I
___
I & III are equivalent
Y = yearbook club
d = drama club
y + d = 84
d = y + 16
now we sub y + 16 in for d in the first equation
y + d = 84
y + (y + 16) = 84
2y + 16 = 84
2y = 84 - 16
2y = 68
y = 68/2
y = 34 <=== yearbook club students
d = y + 16
d = 34 + 16
d = 50 <=== drama club students
