The answer is 9/4. To write that as a mixed fraction, you can write, 2 1/4
Okay what you wanna do it multiple 4.2 and 3.9. if it says "by" it means multiple
<span>Given:
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8.
Simplify Q - [R + S] - T.
Q-(R+S)-T
=</span>7m + 3n - (11 - 2m + n + 5 ) - (-m - 3n + 8)
=7m+2m+m + 3n-n+3n -11-5-8
=10m+5n-24
You can graph that by looking at the y-intercept first. That's where you start to put a point in the coordinate plane or graph.
So go down 1 below 0.
Next, look at the slope.
We know that y = -2x - 1 is in slope intercept form (y = mx+b)
So -2 is our slope. It will be -2/1 because we need a fraction to graph the rise over run and all whole numbers can be a fraction by making 1 as their denominator.
Look at the attachment.
Starting from -1 (y-intercept), go down 2 (-2) then right 1 (1).
To complete the line above, keep the same value and reverse their sign/symbol. So -2/1 will be 2/-1. It goes up 2 then left 1.
I hope you understand and find this answer the most helpful! :)
175 - (8+45÷3)×7
Using BIDMAS
= 175 - (8+15)×7
= 175 - (23×7)
= 175 - 161
= 14
