Answer:10c + 9h
Step-by-step explanation: 4 + 6 = 10
5 + 4 = 9
10 C + 9 H
no need for an equal sign, it is an expression with two terms.
Sorry to hear that you already took the test. Here is how to do the problem:
2ˣ = 128
Let's take log base 10 of both sides.
For simplicity, we'll just use the symbol log to mean log₁₀
log (2ˣ) = log (128) Remember that log(yˣ) = x log(y)
x log (2) = log (128) Divide both sides by log(2) to get x by itself
x = log (128) ÷ log (2)
Answer:
1. x=20 ; the angles are 90 degrees31 degrees 59 degrees
2. x=16; the angles are 16 degrees 92 degrees 72 degrees
Step-by-step explanation:
1. 180=90+31+(3x-1)
180-90-31=3x-1
59=3x-1
60=3x
x=20
plug in x for the third angle
2. 180= x+5x-8+3x+44
180=9x+36
180-36=9x
144=9x
x=16
plug in x to all the angles to find the real value
1/5 is 4/20 in simplest form
hope this helped
