I think the answer would be 45x+20+45y. That is because Bess and Gina both earn $45 per week. We don't know how many weeks they worked for so that is x for Bess and y for Gina. But then Bess earns $20 bonus so you would add that to how much she already earned. They want to know the total amount of money they both earned together. So that would be 45x+20 (Bess) plus 45y (Gina).
Hope this helps!
Answer:
14
Step-by-step explanation:
9 + 4 = 13 and 1/2 + 1/2 = 2/2 = 1 and 13 + 1 = 14
Answer: 7 × ( 3^n - 1 )
Step-by-step explanation:
This is a geometric progression which has its nth term to be
Tn = ar^n- 1. Now from the question given, the sequence are 7, 21, 63, 189. This is an example of a finite sequence, To find the common ratio, you divide the second term by the first term. So
r = 21/7
= 3. , a = 7
Now to find the nth term put the values in the formula above.
Tn =ar^n-1
= 7(3)^n - 1)
= 7 × ( 3^n - 1 ).
Note, it is not 21^n - 1.
The answer should be x=60. ABD are an equilateral triangle all the angles must add up to 180. 60*3=180. Also if you have a protractor you can measure the angle C, the 60 degrees part and measure it against A, D and B. Hope this helps.
A linear equation would be the best fit, but the last point (-1,-7) kinda messes it up. If the -7 would have been a -6 the line y=-2x-8 would fit perfectly.
