Answer:
1161 ft
Step-by-step explanation:
36 ft with the triangles, 900 ft with the squares, 225 ft for the bottom square, so total is 1161 ft.

Step-by-step explanation:
-1 / 2 + x = -21 /4
x = -21/4 + 1/2
x = (-21 + 2)/4
x = -19/4
Answer:
y=2x+3
Step-by-step explanation:
you should see how to get from one number to the next.
I noticed by multiplying an input by 2 then adding 3 I reach my output.
I would use this for each input to find that it would equal my output every time I used the rule
Her average is calculated by the mean, which takes the sum of all her scores and divides it by the number of steps.
Therefore, we just need to set up an inequality using the above formula. I'll call the third test 'x'.
First add all test scores together, divide by 3 and then use ‘>’ to show the left side must be greater than 80:
(70 + 80 + x)/3 > 80
Next, simplify everything. 70 + 80 can be simplified to 150:
(150 + x)/3 > 80
Then multiply both sides by 3. The 3 on the left side cancels out as divide 3 and multiply 3 equals zero:
(150 + x) * 3 > 80 * 3
Now simplify everything again:
150 + x > 240
Now subtract 150 from both sides to isolate the x. 150 - 150 cancels out to zero:
150 + x - 150 > 240 - 150
Now simplify again and you have your answer:
x > 90
From rearranging the inequality, we have found that in her third test (x), she must score above 90 to have an average greater than 80.
