Answer:
-11x
Step-by-step explanation:
-10x - x
Due to -10x being negative, you would add -x and it would then be -11x.
Answer:
84%
Step-by-step explanation:
The empirical rule states that 68% values are within 1 standard deviation of mean, i.e,
70
±
15
or from 55 to 85. Since normal distribution is symmetric, we must have (32%) outside this range, and 32/2=16% on the right if this range. Hence below 85 we have (100-16) % = 84%
X=60
That’s the answer
What I did to get it
(3x-60)=120
+60. +60
3x =180
————. = 60
3
X=60
Hoi!
To solve this, first plug in the values for x and y.
x = 2, so anywhere you see x, put 2 in its place.
y = 3, so anywhere you see y, put 3 in its place.

4 × 2 = 8

× 3 =


=
is your answer.
