I also need help with this two.
1.0.5=41x-2(1.3x-4)
2. 8.7=3.5m-2.5(5.4-6m)
Eliana/Yasmin -- I've already done three problems for you. Now it's your turn.
I'll be glad to check your answers.
A Ball Bounced Four Times,reaching Three Fourths Of Its Previous Height With Each Bounce .after The Fourth Bounce,the Ball Reached A Height Of 27 Cm. how High Was The Ball When It When It Was Dropped?
To solve these equations, let's go step by step. Here's how you can solve each equation:
1. 1.0.5 = 41x - 2(1.3x - 4)
Start by distributing the multiplication across the parentheses:
1.0.5 = 41x - 2 * 1.3x + 2 * 4
Simplify the expression:
1.0.5 = 41x - 2.6x + 8
Combine like terms:
1.0.5 = 38.4x + 8
Now, we want to isolate the variable "x" on one side of the equation. Let's move the constant terms to the right side by subtracting 8 from both sides:
1.0.5 - 8 = 38.4x + 8 - 8
-6.5 = 38.4x
Finally, divide both sides of the equation by 38.4 to solve for x:
x = -6.5 / 38.4
Simplify the result or express it as a decimal or fraction if needed.
2. 8.7 = 3.5m - 2.5(5.4 - 6m)
Distribute the multiplication across the parentheses:
8.7 = 3.5m - 2.5 * 5.4 + 2.5 * 6m
Simplify the expression:
8.7 = 3.5m - 13.5 + 15m
Combine like terms:
8.7 = 18.5m - 13.5
Move the constant terms to the right side by adding 13.5 to both sides:
8.7 + 13.5 = 18.5m - 13.5 + 13.5
22.2 = 18.5m
Finally, divide both sides of the equation by 18.5 to solve for m:
m = 22.2 / 18.5
Simplify the result or express it as a decimal or fraction if needed.
