Answer:
<h2>x=3.5</h2><h3>step-by-step explanation:</h3><h3>to understand the solving steps</h3><h3>you need to know about:</h3>
- trigonometry i.g cos=ad/hypo
- equation
- PEMDAS
<h3>given:</h3>
hypo:6.5
angle:57°
<h3>to solve:</h3>
x
<h3>let's solve:</h3>
according to the question
The formula d = rt describes distance traveled in time and rate of speed. However, we only have the distance and time to place in. This means d = rt would become d / t = r. Once filled in, the problem is now 76 / 1.5 which equals 50.6 (repeating bar over the 6). However, this is the AVERAGE speed of the truck (meaning we are rounding. 50.6 rounded to the nearest speed would be 51 miles per hour.
4x-2y=7 (1)
-3x+3y=10 (2)
3y= 3x+10
y= x+10/3 (3)
sub (3) into (1)
4x-2(x+10/3)=7
4x-2x-20/3=7
2x-20/3=7
+20/3 +20/3
2x= 41/3
x= (41/3) / 2
x= 41/6
sub x= 41/6 into (3)
y= 41/6+10/3
= 61/6
Therefore the point of intersection is (41/6, 61/6)
A + b = 1013;
a - b = 9;
2a = 1022 => a = 511; b = 502;
What you need to find is 80% of 750
There are many ways to figure that out but the way that I did it is to divide 750 by 100. The answer (7.5). Is 1% of 750
In all I had to do was multiply 7.5 x 80. Giving us the answer which is 600
