Answer:
1 skateboard will cost $73 and the other will cost $72
Step-by-step explanation:
Skateboard A (Original) = X
Skateboard B (+$1) = X + 1
Solving for X
(x + 1) + x = 145
2x + 1 - 1 = 145 - 1
2x = 144
2/2 = x
144/2 = 72
x = 72
Answer:
Step-by-step explanation:
Don’t know
Using the Pythagorean theorem:
14^2 = 8^2 + x^2
196 = 64 + x^2
Subtract 64 from both sides:
132 = x^2
Take the square root of both sides:
X = 11.49
Rounded to nearest tenth = 11.5
8.354•11.81=98.66074 pounds
Because the question is asking "about" how much that water weighs, I would round he answer to 99 pounds
Answer:
see explanation
Step-by-step explanation:
a bit more info is needed so this may be wrong.
so first you add up the x values which is 12x+8x+x=21x
then you can see we have a problem, we dont know the x value so the answer would be 21x +3
but we can go a bit further to get an answer as 3(7x+1)
this is also known as factorisation.
so ans: 3(7x+1)
