12+7>9(2-3)-8
19> (-9)-8
19>-17
Step-by-step explanation:
Answer:
75cm
Step-by-step explanation:
11x - 3 = x - 13
-x -x
10x - 3 = -13
+13 +13
10x = 10
---- -----
10 10
x = 1
Answer:
No solutions
Step-by-step explanation:
Let's solve your system by elimination.
10x − 9y = −10
20x − 18y = −28
Multiply the first equation by -2, and multiply the second equation by 1.
−2(10x − 9y = −10)
1(20x − 18y = −28)
Becomes:
−20x + 18y = 20
20x − 18y = −28
Add these equations to eliminate x:
0 = −8
The triangle has sides "a", "b" and "c", where side a = side b and the hypotenuse (side "c") equals side "a" or "b" times the square root of 2.
Prism volume = triangle area * height
342.1 = triangle area * 13.2
triangle area = 342.1 / 13.2
<span><span><span>triangle area = 25.9166666667
</span>
</span>
</span>
area of a triangle is (1/2) base * height
In a 45 45 90 triangle, the base = height and since we don't know either the base or the height we'll call both "x".
So triangle area = (1/2) * x^2
<span>25.9166666667 = (1/2) * x^2
x^2 = </span><span>51.8333333334
x ( the base and the height) = </span><span><span><span>7.1995370222
</span>
</span>
</span>
<span>
</span>
the hypotenuse of a 45 45 90 triangle = leg * square root (2) =
hypotenuse = <span>7.1995370222 * sq root (2)
</span><span><span><span>hypotenuse = 10.1816828995
</span>
</span>
</span>
So, one of the legs = <span><span>7.1995370222
