23/4
Step by step:
5/1 + 3/4
5/1 • 4 = 20/4
20+3/4
23/4
.725 , .572 , .275, .2
You look at the first decimal place to see which is the greatest. 7 is greater than 5 and 2 so it's first. Then 5 is greater than 2 so it is next. For the last two numbers since 2 is the same value you look at the next decimal place. Since 7 is greater than 0 it comes next!
the answer would be 10 because you have to times by 2.5 on both sides to get t on its own.
4 × 2.5 is 10
Multiply each of the numbers by a ten to a power that they both become whole numbers.
0.67 *
= 67
0.3 *
= 30
Divide as usual.
67 / 30 = 2
So, the answer is 2 1/3.
Using f(x) = y, we know that a graph of the function contains the (x,y) points (2,5) and (6,-1). first find the slope of that line,
m = (y2 - y1)/(x2 - x1) ⇒ -6/4⇒-3/2
then using either point (I'll use the first one) solve for b in y = mx + b.
5 = (-3/2)(2) + b⇒ 5 = -3 + b⇒ 8 = b.
So y = (-3/2)x + 8 ⇒ f(x) = (-3/2)x + 8.
