Answer:
x= 3.5
Step-by-step explanation:
Substitute the variable x with what it's equal to, x= 20-y
7(20-y)-8= y
Distribute into the parenthesis.
140-7y-8= y
Subtract common numbers.
(140-8)-7y= y
132-7y= y
Move the constant to the right.
132-7y= y
-132 -132
-7y= y-132
Subtract y to both sides.
-7y= y-132
-y -y
-8y= -132
Divide to both sides by -8
<u>-8y</u>= <u>-132</u>
-8 -8
y= 16.5
Now, add the y value to the equation.
x= 20- (16.5)
x= 3.5
Answer:
The fifth term is 8.
Step-by-step explanation:
Give n=5 in the general term
T 5=3(5)-7 = 15–7 =8
Another method
Tn = 3n - 7
T 1 = 3(1)-7 = -4
T 2 = 3(2) -7= -1
d= t 2 - t 1 = -1 -(-4)=3
a = -4 d=3
Tn = a + (n-1)d =
T 5 = a + (5–1)d = a +4 d = -4 +4(3)= 8
