Answer:
If we are choosing students at random from all students who got a B:
Total number of non-female students who got a B: 19
Total number of students who got a B: 36
Probability: 19/36
If we are choosing students at random from all students:
Total number of non-female students who got a B: 19
Total number of students: 78
Probability: 19/78
Answer:
Step-by-step explanation:
I think your question is to write WRITE A SYSTEM OF EQUATIONS in that situation.
And here is my answer:
- Let m - the number of minutes
1. The first choice is to pay $10.00 per month plus &0.09 per MB of data
<=> y = 0.09m + 10
2. The second choice is to pay $16.00 per month plus $0.07 per MB of data
<=> y = 0.07m + 16
So the system of equation is:
Hope it will find you well.
Take x common from the denominator
and simplify
Answer:
y = - 2x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ← m is the slope
To calculate m use the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (0, 0) ← 2 points on the line
m = = = - 2
y = - 2x ← equation of line
Answer:x=7
Step-by-step explanation:
Use BODMAS
Open bracket first
2x+4+x=8+2(3+x)-3
2x+4+x=8+6+2x-3
2×+x-2x=8+6-3-4
×=7
