Answer:
110 chairs.
Step-by-step explanation:
(9x6) + (8x7) First multiply 9x6 and 8x7.
(54) + (56) In the first parenthesis, we have 9 tables with 6 chairs each. We are going to add that to the second parenthesis with 7 tables and 8 chairs each.
= 110 There are 110 chairs.
Her average now is 88.
She needs to bring it up to a 90.
Let's start with if she gets a 90.
88 + 90 = 178
178/2 = 89
A 90 would only get her an average of 89, so you need to go higher.
88 + 91 = 179
179/2 = 89.5
88 + 92 = 180
180/2 = 90
She must get at least a 92 to get an average of 90.
Answer:
Step-by-step explanation:
Your answer would be y< -3/2x+1
You slope is negative because the line goes from left to right and your slope is -3/2 because it rises 3 and goes to the left 2. Remember that your slope represents your rise over your run.
Your equation is also only > and not less then or equal to because it is a dotted line.
Happy studying!
