4x + 15 = 6x + -11
Reorder the terms:
15 + 4x = 6x + -11
Reorder the terms:
15 + 4x = -11 + 6x
Solving
15 + 4x = -11 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
15 + 4x + -6x = -11 + 6x + -6x
Combine like terms: 4x + -6x = -2x
15 + -2x = -11 + 6x + -6x
Combine like terms: 6x + -6x = 0
15 + -2x = -11 + 0
15 + -2x = -11
Add '-15' to each side of the equation.
15 + -15 + -2x = -11 + -15
Combine like terms: 15 + -15 = 0
0 + -2x = -11 + -15
-2x = -11 + -15
Combine like terms: -11 + -15 = -26
-2x = -26
Divide each side by '-2'.
x = 13
Simplifying
x = 13
Answer:
hello : 6.23x10^14 > 8.912x10^12^12
Step-by-step explanation:
let : A= 6.23x10^14 and B = 8.912x10^12
A= (6.23x10^2) x10^12 ... because : 10^14 = 10^2x10^12
A = 623 x 10^12
623 > 8.912
so : A > B
Answer: Game land sells 20 crayons for 5 cents less.
Step-by-step explanation:
Hi, to answer this question we have to calculate the price per crayon in each store, by dividing the amount paid in each case by the number of crayons that each store offers.
Toy world (T): 25/4 = 6.25 cents per crayon
Game land (G): 30/5 = 6 cents per crayon
Now, we have to multiply the cost per crayon by 20.
T=6.25 x 20 = 125 cents
G=6 x 20 =120 cents
So, comparing both costs, Game land sells 20 crayons for 5 cents less.
125-120 = 5 cents
