1078 / (5+6) = 98
Like - 5 x 98 = 490
Dislike - 6 x 98 = 588
In doing this you can use the factoring method to do this faster. Start by dividing both sides by two to simplify the equation. X^2 now equals 100.
You can move 100 to the other side of the equation so that x^2-100=0. You can now factor and solve using the zero product property.
x^2-100=0
(x+10)(x-10) = 0
x equals 10 and -10.
Answer:
A
Step-by-step explanation:
The measure of angle D can be found using the Interior Angle Sum of a Triangle.
The angles of a triangle add to 180. This means:
90 + 21 + x = 180.
111 + x = 180
x = 69
The solution is A.
Angle B is smaller than Angle D which means CD will be smaller than BC.
B: Apply the distributive property to get 4x - 12=9
Answer: 3.5 h
Step-by-step explanation:
<u>1. Data:</u>
a) s = 740 miles / h
b) d = 2,567 miles
c) t = ?
<u>2. Equation:</u>
<u>3. Solution:</u>
- Solve the equation for t:
s = d / t ⇒ t = d / s
t = 2,567 miles / (740 miles/h) ≈ 3.47 h ≈ 3.5 h
