Answer:
3x
Step-by-step explanation:
What you know
This is an equilateral triangle
the x's are all the same
you could write x + x + x = 3x = 16
Multiplying is just adding repeatedly
Answer:
brown = 12
yellow = 30
orange = 36
Step-by-step explanation:
let 'b' = # brown
let '18+b' = # yellow
let '3b' = #orange
add them together and set equal to 78
b + 18 + b + 3b = 78
5b + 18 = 78
5b = 60
b = 12
y = 12 + 18 = 30
o = 3(12) = 36
12 + 30 + 36 = 78
Answer:
10lbs because you would multiply 4.5 by 2.205 which would be 9.9208 which would round to ten
Step-by-step explanation:
Thank you ! You have done all the heavy lifting for us,
and given us the expression in factored form.
The factors are (y - 2) and (x + 3) .
2x-7+-6x-3 2x+-6x=-4x
-4x-10=0
-5/2 is the answer
