Answer:
<B = 70°
Step-by-step explanation:
First we need to find x, lets plugin these two equations.
2x - 30 = x + 20
Then find like terms
2x = x + 50 =
x = 50
Then we plugin 50 for x
2(50) - 30 =
100 - 30 = 70
<B = 70°
You can only simplify it, because you can't add a number with x to a number without, so it would be 7x+7
Answer:
The value of n depends on the questin. N would be a variable in an equation.
Step-by-step explanation:
For example. 2*n=6
n is the variable in the equation. Therefore, the value of n is 3. Because 2*3=6.
It took 50 hours to produce 3 oz of honey.
<u>Step-by-step explanation:</u>
Rate of production= 1.5% per hour
Initial amount of honey = 4 oz
Final amount of honey = 7 oz
Honey produced = 3 oz
Amount produced = (initial amount x rate x time) /100
3 = (4 x 1.5 x t) /100
300 = 6t
t = 300/6
t = 50 hours
It took 50 hours for the bees to produce 3 oz of honey.
