Answer:-3/4
Step-by-step explanation:
5x+2=x-1
5x-x=-1-2
4x=-3
X=-3/4
It's basically 30 divide by 3/5
which becomes 30*5/3
The answer is 50
3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
Answer:
80
Step-by-step explanation:
You need to calculate the circumference of this wheel to determine how far it travels with each revolution.
First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.
You need to calculate the circumference of this wheel to determine how far it travels with each revolution.
First, you need to know the diameter of a circle, which is the length of a straight line drawn through the circle.
The magic number here is pi, which is roughly 3.14159265. The digits to the right of the decimal point continue infinitely.
Dividing a circle’s circumference by pi will give you a circle’s diameter.
Multiplying a circle’s diameter by pi will give you a circle’s circumference.
Answer:
585
Step-by-step explanation:
let 'f' = females
based on sample, set up this proportion:
32/75 = f/1371
cross-multiply:
75f = 1371(32)
75f = 43872
f = 584.96
