Answer:
a) 7/2 or 3.5
b) 4.8
form equation and solve them
a}n = 17
Explanation:
a) 2m + 8 = 15
Subtract 8 from both sides: 2m + 8 - 8 = 15 - 8
Simplify: 2m = 7
Divide both sides by 2: (2m)/2 = 7/2
Simplify: m = 7/2 or 3.5
b) 10x - 3 = 45
Add 3 to both sides: 10x - 3 + 3 = 45 + 3
Simplify: 10x = 48
Divide both sides by 10: (10x)/10 = 48/10
Simplify: x = 4.8
To form and solve an equation for Ashley’s problem, we need to translate the words into mathematical expressions. Here are the steps and solution:
a) Ashley thinks of a number if i double my number and add 6 the answer is 40
Let n be Ashley’s number.
If we double the number, we get 2n.
If we add 6 to the doubled number, we get 2n + 6.
The answer is equal to 40, so we can write an equation: 2n + 6 = 40
To solve for n, we need to isolate it on one side of the equation by using inverse operations.
Subtract 6 from both sides: 2n + 6 - 6 = 40 - 6
Simplify: 2n = 34
Divide both sides by 2: (2n)/2 = 34/2
Simplify: n = 17
