solve: 4+8 1/2 -:- (1/4) to the third power.
solve -11-(x+30)=-41-2 (5x-18)
please show your work
can someone please help me with this one,
From your information, I do not know how to deal with the first problem. "/" is used online to indicate division.
-11-(x+30)=-41-2(5x-18)
Get rid of parentheses.
-11-x-30 = -41-10x-36
Combine like terms.
9x = -36
x = -4
thank you
To solve the expression 4+8 1/2 -:- (1/4) to the third power, follow the order of operations (also known as PEMDAS/BODMAS):
Step 1: Simplify within the parentheses.
Since there are no parentheses, move to the next step.
Step 2: Simplify any multiplication or division.
In this case, the division operation -:- (1/4) means to divide by (1/4). To simplify, we multiply by the reciprocal:
4 + 8 1/2 * (4/1)
Now we can multiply:
4 + (8 * 4/1) + 1/2
Simplify further:
4 + 32 + 1/2
Step 3: Simplify any addition or subtraction.
To add the whole numbers and fractions, convert the whole number into a fraction with the same denominator as the fraction:
4 + 32/1 + 1/2 * (2/2)
Combine fractions:
4 + 32/1 + 2/2
Convert 4 to a fraction:
4/1 + 32/1 + 2/2
Now, find a common denominator (which is 2 in this case) and add the fractions:
(4 + 32 + 2) / 1 = 38/1 = 38
Finally, raise it to the third power:
38^3 = 38 * 38 * 38 = 54,872
To solve the equation -11 - (x + 30) = -41 - 2(5x - 18), we'll follow these steps:
Step 1: Simplify within the parentheses.
-x - 30 = -41 - 10x + 36
Step 2: Combine like terms on both sides of the equation.
Starting with the left side:
-x - 30 = -10x + 36
Step 3: Isolate the variable on one side.
To do this, we'll move all the terms with x to the left side and the constants to the right side.
-x + 10x = 36 + 30
Combine the like terms:
9x = 66
Step 4: Solve for x.
Divide both sides of the equation by 9:
(9x)/9 = 66/9
x = 22
So, the solution to the equation is x = 22.
