Answer:
x=-7
Step-by-step explanation:
Regroup terms.
8x-2=7x-98x−2=7x−9
2 Subtract 7x7x from both sides.
8x-2-7x=-98x−2−7x=−9
3 Simplify 8x-2-7x8x−2−7x to x-2x−2.
x-2=-9x−2=−9
4 Add 22 to both sides.
x=-9+2x=−9+2
5 Simplify -9+2−9+2 to -7−7.
x=-7x=−7
Answer:
= 11
Step-by-step explanation:
using the rule of logarithms
x = n , then x = , so
11 = a ⇒ 11 =
Answer: 5.4
Step-by-step explanation:
Use cosine to find the adjacent side.
cosine = adjacent/hypotenuse
Substitute these values in the cosine equation:
cos(39) = x/7
7*cos(39) = x
Use a calculator to find the value of x:
x = 5.4
