Answer:
The value of x is 1
Step-by-step explanation:
1/2 x - 3/4 = 3/8 - 5/8 x
1/2 x + 5/8x = 3/8 + 3/4
9/8 x = 9/8
x = 1
Answer:
yes it is
Step-by-step explanation:
Answer:
Step-by-step explanation:
Plug x for y and y for x.
y = 2x^2 + 2
x = 2y^2 + 2
Then isolate the y variable.
x - 2 = 2y^2
sqrt(x - 2) = 2y
(sqrt(x - 2))/2 = y
Answer:
About 40 students are left handed
Step-by-step explanation:
The answer is 22
<span>The sum of two numbers is 48:
x + y = 48 </span>⇒ x = 48 - y
<span>One third of one number is 5 greater than one sixth of another number:
1/3x =5 + 1/6 y </span>
<span>
1/3(48 - y) = 5 + 1/6y
1/3 * 48 - 1/3 * y = 5 + 1/6 y
16 - 1/3y = 5 + 1/6y
16 - 5 = 1/6y + 1/3y
11 = 1/6y + 2/6y
11 = 3/6y
y = 11 * 6 / 3
y = 22
x = </span>48 - y
x = 48 - 22
x = 26
The smallest number is 22.
