Answer:
There is a area of triangle and there is two trapezium so 8×17=136
They are vertical angles meaning 142 is equal to 3x + 22. Put them equal to each other and solve for x.
Hello from MrBillDoesMath!
Answer:
Discussion:
I stared at the numbers 19, 29, 39, 49, 59, 69,... for a second and noticed that adding 10 to any number gives the next number to the right. For example,
19 + 10 = 29
29 + 10 = 39
39 + 10 = 49
etc.....
A recursive formula would be:
a(0) = 19
a(n+1) = a(n) + 10 if n >= 0

Answer:
t = 0
Step-by-step explanation:
(7t - 2) - (-3t + 1) = -3(1 - 3t)
because you can not do anything inside the parantheses, you distribute. there aren't any numbers on the left side of the parantheses on the left side of the equation so we just imagine the number 1. on the right side of the equation, just distribute normally
[ 1(7t - 2) -1(-3t + 1) = -3(1 - 3t) ]
will be
7t - 2 + 3t - 1 = -3 + 9t
add like terms
10t - 3 = -3 + 9t
subtract 9t from both sides
t - 3 = -3
add 3 to both sides
t = 0
