Answer:
Step 2
Step-by-step explanation:
In step 2 the expression was 40+20 which would have been 60 but he might have thought addition sign was subtraction so he did 40-20 which is 20 so he is wrong made mistake in step 2

The second bank that offers 8% for 7 years will yield the most money.
Bank 1: 100,000 x 10% x 5 = 50,000
Bank 2: 100,000 x 8% x 7 = 56,000
Answer:
z = 7 and z = 69
Step-by-step explanation:
In the given figure, two lines are cut each other.
Here we have to use the following property.
If the two lines intersect each other, then the opposite sides are equal.
Therefore, 11x + 34 = 111
Now we have to find the value of x.
Solve for x.
11x = 111 - 34
11x = 77
Dividing both sides by 11, we get
x = 77/11
<u> x = 7</u>
Now we have to find the value of z.
Adjacent angles add upto 180 in a straight line.
Therefore, 111 + z = 180
Subtract 111 on both sides, we get
111 + z -111 = 180 - 111
<u>z = 69</u>
Therefore, z = 7 and z = 69
Hope you will understand the concept.
Thank you.
