The value of x is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−9/4
Answer:
70 students
Step-by-step explanation:
As, 30% Mike surveyed
And these 30% are 21 students
So 30% of X = 21
= 30/100 x X = 21
= 30X = 2100
So X = 2100/30
X = 70
So 70 students were surveyed
The quantity remaining will be
.. 448*(1/2)^(24/6) = 448/16 = 28 . . . . grams
Answer:
(-3,5)
Step-by-step explanation:
When you reflect over the x axis, the y value's sign changes.
So we have:
-3,5
Answer:
x = -4
Step-by-step explanation:
Step 1: Define
j(x) = 3x + 1
j(x) = -11
Step 2: Substitute and solve for <em>x</em>
-11 = 3x + 1
-12 = 3x
x = -4
