Total amount of cash the student earns per hour is $7.5, let the time taken to earn $200 be h, thus the inequality representing this will be:
7.5h≤200
thus
h≤80/3
writing in whole numbers we shall have:
h≤27

Here is their argument. given the obtuse angle x, we make a quadrilateral abcd with ∠dab = x, and ∠abc = 90◦, and ad = bc. say t

svp [43]

Answer:

The error in the argument is in assuming that the line from p to d passes through line ab - that is, that pd crosses below a. But actually pd passes above a. This means that the angle pad is not equal to x + pab, but rather angle pad = 360-(x+pab). The rest of the "proof" then falls apart.

combine like terms to simplify each expression. 1: 3/4z(3)+4-1/4z(3). 2: 3.4m+2.4m. 3: 4.2n+5-3.2n. 4: q(5)+q(5)+q(5). 5: 3x+1/4

Temka [501]

Explanation and steps to the expressions are marked in order in the images below.

1. Answer is 3z/2 + 4

2. Answer is 5.8m

3. Answer is n + 5

4. Answer is 15q

5. Answer is 10x + 1/2 + y

6. Answer is 8z + 4.2

The maximum is five images, so I cannot add the last explanation and steps for the last expression.
