Answer:
-9
Step-by-step explanation:
18÷x = -2
18 = -2×x
18 = -2x
-9 = x
x = -9
To solve the first problem, you have to multiply both sides by 3, or 3/1.
3/1(n/3)=2(3)
3n/3=6
1n=6, or n=6.
To solve problem 2, simply divide both sides by 5.
5t/5=20/5
t=4
Hope this helps :-)
Answer:
b = 8√3 mm, a = 16 mm, x = 5 ft, y = 5√2 ft.
Step-by-step explanation:
With 30° 60° 90° triangles, one side will be a number, the other leg will be that number multiplied by √3, and the hypotenuse will be 2 times that original number.
So in this case:
The original leg's length is 8 mm. Side b will be that 8 times √3.
So, b = 8√3 mm.
Side a will be 8 times 2.
So, a = 16 mm.
With 45° 45° 90° triangles, the two legs will be the same length, and the hypotenuse will be that number times √2.
So in this case:
The original leg's length is 5 ft. Side x will be that same length.
So, x = 5 ft.
Side y will be 5 times √2.
So, y = 5√2 ft.
