Answer:
Use the value for the variable to solve for the other unknowns. Substitute the value for the variable into the expression for the number of seats on the middle level. Substitute the value for the variable into the expression for the number of seats on the lower level.
Answer: and
Step-by-step explanation:
Since, here
And we know that
So
Thus,
Now, we know that
Thus,
5x(68-75/98)+y=2
5x(67.2) + y = 2
336x + y = 2
The answer is 336x + y = 2
Hi there!
We know that RST is an equilateral(all 3 sides the same length) triangle, and is therefore equiangular(all 3 angles the same value). Therefore, angle S and is equal to one-third of the triangle's angle measure.
180/3=60
60=7x+4
56=7x
x=8

Let's solve your equation step-by-step.<span><span><span><span>x2</span>−<span>7x</span></span>+12</span>=0
</span>Step 1: Factor left side of equation.<span><span><span>(<span>x−3</span>)</span><span>(<span>x−4</span>)</span></span>=0
</span>Step 2: Set factors equal to 0.<span><span><span>x−3</span>=<span><span><span>0<span> or </span></span>x</span>−4</span></span>=0</span><span><span>x=<span><span>3<span> or </span></span>x</span></span>=4
</span>Answer:<span><span>x=<span><span>3<span> or </span></span>x</span></span>=<span>4
Good luck mate :P</span></span>
