Answer:
140
Step-by-step explanation:
I think you mean "lowest common denominator" where you use the word "benchmark."
The LCD of 3/7 and 16/20 is 140; 140 is the smallest number evenly divisible by both 7 and 20.
Then 3/7 → 60/140 and 16/20 → 112/140. 112/140 is between 1/2 and 1.
Answer:
x= -17/9
Step-by-step explanation:
hope this helps!!!
Directly proportional to x
z=kx
And inversely proportional to y
z=kx/y we are given the point (x,y,z) of (3, 6, 9.5) so
9.5=3k/6 now multiply both sides by 6
57=3k divide both sides by 3
19=k so now that we know the constant of proportionality:
z=19x/y, and we want to solve for z when x=8 and y=12 so:
z=19(8)/12
z=12 2/3 exact
z≈12.667 (rounded to the nearest thousandth)
Answer:
B 244
Step-by-step explanation:
You can split up the polygon into two separate rectangles, one smaller one on top and one bigger one below.
Area of smaller rectangle = 6 × (14-8)
= 36
Area of bigger rectangle = 26 × 8
= 208
Total area of polygon = 36 + 208
= 244
Answer:
D) 7/2
Step-by-step explanation:
y=1/3 (ax-2) =>(2,3) so x=2, y=3.
Then,3=1/3 (2a-2)=> 9=2a-2 and a=7/2
So, slope is 7/2
