Step-by-step explanation:
- Move all terms not containing n to the right side of the equation.
7n = 31 + 4
7n = 35
- Divide each term by 7 and simplify.
n = 5

Answer: Multiply 70 and 7
Step-by-step explanation:
because you have to follow pemdas
For every 100, she gives away 25. so in 1200 there are 12. so we multiply by 25. 25×12=300
3.75p<=20
divide by 3.75
p < 5 1/3

The problem above uses a combination of sine and cosine law of triangle to solve for the m∠B.
Given:
<span>m∠A = 60°, b = 9 and c = 6
Cosine Law:
a^2=b^2+c^2-2bccosA
a^2=(9)^2+(6)^2-2(9)(6)cos(60)
a^2=81+36-54
a^2= 63
a=</span>

Sine Law

sin B= 9/

sin 60
sin B= 0.98198
B= sin ^-1 (0.98198) = 79.10
Therefore, m∠B is equal to 79.10
