What value of x makes the equation below true? -26 = 60 + x
Answer:
x = -86
Step-by-step explanation:
60+ (-86)= -26
Answer:
x = -86
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-26 = 60 + x
Step 2: Solve for x
Subtract 60 on both sides: -86 = xRewrite: x = -86Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -26 = 60 - 86Subtract: -26 = -26Here we see that -26 does indeed equal -26.
∴ x = -86 is the solution to the equation.

9 oranges cost $3.60. How much are 4 oranges?
Answer:
$1.60
Step-by-step explanation:
Set up an equation where you have the total oranges (o) on top and the cost (c) on the bottom. So you will have two fractions equaling each other. So you will have o/c=o/c. Now you just have to replace the variables with what you know. 9 oranges= $3.60, and you want to know how much 4 oranges cost. Since the cost per orange is the same, no matter how many oranges you buy if you divide the amount of oranges by the price you will always get the same number. So replace the variables with the numbers you know and you get,
9/$3.60=4/c
Now to solve an equal fraction problem, simply cross multiply (multiply the two numbers diagonal so 4 and 3.6), and divide (take the multiplied number and divide by the number remaining which will be the number diagonal from the variable) which gives you $1.60 for four oranges.

Dylan opened a credit card account with $575.00 of available credit. Now that he has made some purchases, Dylan's account only has $465.75 of available credit. What is the percentage decrease of the amount of available credit in Dylan's account?
A.
14%
B.
81%
C.
19%
D.
23%
Answer:
C.) 19% decrese
Step-by-step explanation:
575.00 - 465.75 = 109.25
109.25/575.00 = 0.19
0.19 = 19%
575.00 - 465.75 = 109.25
109.25/575.00 = 0.19 = 19%
Therefore, the percentage decrease of the amount of available credit in Dylan's account is 19%.
