Answer:

Step-by-step explanation:
we know that
The algebraic expression of seven-tenths is equal to the number 7 divided by ten

The algebraic expression of the product of 5p and 3 is equal to multiply 5p by 3

therefore
The algebraic expression of seven-tenths of the product of 5p and 3 is equal to

Answer:
n = 3
e = 5
Step-by-step explanation:
10n + 3e = 45
2n + 5e = 31
10n + 3e = 45
10n + 25e = 155
o + 22e = 110
e = 5
to fix 5 into the first equation
10n + 3(5) = 45
10n + 15 = 45
10n = 45 -15
10n = 30
n = 3
Answer:
The equation of the line would be y = -1/2x - 15
Step-by-step explanation:
To find the equation, we need to start by looking at the original equation's slope, which is 2. Perpendicular lines have opposite and reciprocal slopes, so the new line will have a slope of -1/2.
Now we use that and the point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 10 = -1/2(x + 50)
y - 10 = -1/2x - 25
y = -1/2x - 15
Answer:
0.2239
Step-by-step explanation:
Given that you have two hats. In one hat are balls numbered 1 through 15. In the other hat are balls numbered 16 through 25. I first choose a hat, then from that hat, I choose 3 balls, without replacing the balls between selections.
Either I or II hat can be selected.
Prob of selecting any one hat = 0.5
After selecting I hat, selecting 3 balls can be done in 15C3 ways and from II hat it can be done in 10C3 ways.
total no of ways of selecting 3 balls = (10+15)C3 = 2300
