977- (356+365) = x
356+365= 721
977- 721 = 256
x= 256
256 students in the sixth grade
Divide 960 by 15
960/15 equals 64
so it's 64 miles per hour
Answer:
XW = 4 units
Step-by-step explanation:
Given tanf° = 
, then
tanf° = 
= 
= 
= ( cross- multiply )
2XW = 8 ( divide both sides by 2 )
XW = 4
Answer:
(x-4)2=-13
Step-by-step explanation:
2x+13=8
2x-8=-13
2(x-4)=-13
Given;
6Ln (x + 2.8) = 9.6
We will transpose 6 in the Ln, so that we will leave Ln alone.
Ln (x + 2.8) = 9.6/6 = 1.6
we divide the 9.6 to 6 and we get 1.6
x + 2.8 = e^1.6
e^ for the substitution of Ln
x = e^1.6 - 2.8
insert the e^(1.6) in the calculator and you will get 4.95303242439511 and subtract 2.8 and you will get the answer.
x = 2.153
2.153 is the final answer in this question.
