Answer:
no solution
Step-by-step explanation:
1/2(2-4x)+2x=13
We simplify the equation to the form, which is simple to understand
1/2(2-4x)+2x=13
Simplifying:
+ 0.5*(2-4x)+2x=13
Reorder the terms in parentheses
+(+1-2x)+2x=13
Remove unnecessary parentheses
+1-2x+2x=+13
We move all terms containing x to the left and all other terms to the right.
-2x+2x=+13-1
We simplify left and right side of the equation.
0x=+12
0=12
The left and right sides are not equal, therefore there is no solution. This equation is invalid.
Answer:
160
Step-by-step explanation:
Is means equals and of means multiply
24 = 15% * N where N is the unknown number
Change to decimal form
24 = .15 N
Divide each side by .15
24/.15 = .15N/.15
160 = N
1) h ≥ 19
2) y > 6
3) 2x ≤ 10
x ≤ 5
4) 9x ≤ 45
x ≤ 5
Answer:
Irrational number, any real number that cannot be expressed as the quotient of two integers. For example, there is no number among integers and fractions that equals the square root of 2. ... Each irrational number can be expressed as an infinite decimal expansion with no regularly repeating digit or group of digits.
Answer:
Step-by-step explanation:
Let x be the normal body temperature
X is N(99, sigma)
Sample mean x bar = 98.2 and s = 0.63
Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285
It is safe since 1.5 <1.96 critical value of z at 95%
