Let x = smallest number
y = middle number
z = largest number
Equations:
sum of 3 numbers: x + y + z = 15
two times smallest is 1 less than largest: 2x = z - 1
sum of largest and smallest is 10: z + x = 10
z + x = 10 can be solved for z ⇒ z = 10 - x
substitute into 2x = z - 1 ⇒ 2x = 10 - x - 1
3x = 9
x = 3 (divided both sides of equation by 3)
Since z + x = 10 ⇒ z + 3 = 10 ⇒ z = 7
Substitute values for x and z into x + y + z = 15 ⇒ 3 + y + 7 = 15
y + 10 = 15
y = 5
answer: 3, 5, 7
You know that’s tuff that’s really tuff that’s literal overdose in words just like I would answer it if you can make it into an equation instead of a word problem
Answer:
$2450
Step-by-step explanation:
One week = 7 days
$350 = 1 day
$ 2450 = 7 days(1 week)
350 * 7 = 2450
Answer: 8
Orignal Equation : 5x + 16 = 56
Step 1 - Subtract 16 from each side to get 5x alone.
5x + 16 - 16 = 56 - 16
5x = 40
Step 2 - Get x alone
5x/5 = 40/5
x = 8
