Distribute the exponent to each term, then move your negative exponents to the opposite side then simplify.
Answer:
t= .43
Step-by-step explanation:
8t + 3 -t
8t - t = 7t
7t + 3
7t/7 = t
3/7 = .43
t= .43
Answer:
(3,-4) or x=3 and y= -4
Step-by-step explanation:
I'm going to solve this by substitution
We first need to get a variable by itself in one of the two equations (it doesn't matter which variable and the equation you do the work on doesn't matter either)
I'm going to solve for y in the second equation
-4x-4y=4
add 4y and subtract 4 from both sides to get
-4x-4=4y
Divide by 4 to get
-x-1=y
We can plug this value in for y into the first equation and get
4x+5(-x-1)= -8
Solve for x
4x-5x-5= -8
-x-5= -8
-x= -3
x=3
We can plug this value into one of the first two equations and solve for y
4(3)+5y= -8
12+5y= -8
5y= -20
y= -4
Therefore the solution is (3,-4) or x=3 and y= -4
Answer:
x = 6
Step-by-step explanation:
8x + 2 + 70 + 60 = 180
8x + 132 = 180
8x = 48
x = 6
I believe you can do x + 2.7 = 16.
I took geometry last year and those arrow things are basically saying the line is the same if they have the same number of arrows. Using that logic, you can equal them out and find X.
Your answer is 16 - 2.7
(13.3)
