Alvin is 8 years older than Elga. The sum of their ages is 78. What is Elga's age?
Mazyrski [523]

Answer:

35

Step-by-step explanation:

ok let's look at these old farts.

alvin is 8 years older than elga, so elga needs 8 more years to be as old as Alvin is. AKA,

Alvin = Elga + 8

The sum of their ages is 78.

Alvin + Elga = 78

Now put the equations together,

(Elga + 8) + Elga = 78

2 * Elga = 70

Elga = 35

Therefore, Elga is 35 years old! So old !!

Xelga [282]

Hello there!

35/100 watch more then 10 hours a week

3000 is 30 times greater than 100 so we can simply multiply 35/100 by 30.

35/100 x 30 = 1050/3000

Therefore, if the company had 3,000 subscribers, 1,050 subscribers would be watching more than 10 hours a week.

Answer:

y=-3x+7

Step-by-step explanation:

y=mx+b is the formula you are going to end up once completed.

This, by given two points:

(4,-5) (3,-2)

\frac{-2-5}{3-4} = Point-Slope Intercept Form

\frac{3}{-1} = After subtracting both from above

-3 = is your slope, decreasing.

Substitute -3 for y=mx+b

y=-3x+b

Use one of the given points (any) to find what b equals.

(4,-5)

x    y

-5=-3(4)+b

-5= -12+b

7=b

Final Equation:

y=-3x+7
