Answer:
-⅖
Step-by-step explanation:
We need to simplify the given equation and find out the value of a , as ,
=> 3(a-1)+31-11a = 4(2a+3)
=> 3a -3+31-11a = 8a + 12
=> -8a -28 = 8a + 12
=> 16a = -28-12
=> 16a = -40
=> a = -2/5
<h3>
• Hence the value of a is -⅖ .</h3>
Answer:
A
Step-by-step explanation:
Similar figures have sides in the same ratio
169/1.3 = 17/x
x = 17×1.3/169
x = 0.131 m
Why?
The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".
Calculating we have:
Now, we can calculate "f" by using the formula to calculate the area of the triangle:
Now, finding "g" by using the formula to calculate the area of the rectangle, we have:
Hence, we have that:
Have a nice day!
Answer:
No
Step-by-step explanation
Because 20 more pages would take 35 more minutes which would be 40 pages at 70 mines then you will divide your 7 pages left by the 35 minutes it took to read the the first two 20 page sections of the book.
35 min.+ 35 min = 70 min. 35 mins./7 pages = 5 mintes
So it took a total of 75 minutes for Line to read her 47 page book.
