Answer:
it is the 1st one
Step-by-step explanation:
because you have to add up all three sides because you need 180 then subtract that answer from 180 and you will get your answer
Answer:
x = - 6
Step-by-step explanation:
Let x b number, according to instructions´ we must
1.-Multiply by 4
2.-Subtract 6
3.-Divide by 2
4.-Arturo says his new number - 15
4,.Which one was the original number ??
The maths expression for that is :
(4*x - 6 ) / 2 = - 15
we solve for x
4x - 6 = - 30
4x = - 24
x = - 6
Answer:
No
Step-by-step explanation:
equation is y=2x+3
The point we have is (15,29)
i.e. x=15 and y=29
if we put x=15 in the equation we should get the value of y=29
y=2(15)+3
=30-3
=27
Here, we didn't get y=29 instead we got y=27
So the point (15,29) doesn't follow that equation
Answer:
yes
there would be 7525 runners
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r) n
FV = Future value
P = Present value
R = interest rate
N = number of years
6500 x (1.05)^3 = 7525 runners
See, pls, the offered decision:
1. this ratio has another form: 2x/3x/4x;
2. the difference between the largest and the smallest is 4x-2x=10.
Then x=5, and the sequence of numbers is 10/15/20, where 15 is the middle number.
Answer: 15.
