1) its an iscoceles triangle so the two angles at the base are equal
180-18
= 162/2
x = 61 degrees
2) x is 90 degrees since its a right angle.
angle b is 47 as its an iscoceles triangle.
180 - 47 - 90
y = 43 degrees
2^x =20
take log() for both sides
xlog(2) = log(20)
x= log(20)/log(2)
x= 4.322
-22 > -5x - 7 > = -3
equivalent one is :
a. -5x - 7 < -22 and -5x - 7 > = -3
Answer:
1/3
Step-by-step explanation:
If Mackenzie drinks 8 ounces of water per 24 hours, that could be written as a ratio and a fraction. 8:24, 8/24
8/24 in its simplest form is 1/3.
Combine like terms to simplify.
3z + 5z = 8z
4 - 9 = -5
8z - 5
Answer: 8z - 5
