Hi there!
To solve this problem, we need to simplify.
2/3x = 12
To isolate x, we should multiply both sides of the equation by the reciprocal of 2/3 to make x equal to a value:
Reciprocal of 2/3 = 3/2
x = 12 * 3/2
x = 18
Hope this helps!
Answer:
105 feet.
Step-by-step explanation:
The longer diagonal is opposite the longer angle in the parallelogram.
The longer angle = 180 - 36 = 144 degrees. (Reason: he same side angles are supplementary).
So, by the law of cosines:
x^ 2 = 40^2 + 70^2 - 2*40*70 cos 140 where x = the diagonal.
x^2 = 11030.50
x = 105.03 feet.
Let's call our number <em>x</em>.
So we can setup the equation x² = 100.
To solve this equation, we square root both sides.
So we have x = ±10.
Always use plus or minus when square rooting both sides
of an equation so our answer is not only 10, it's also -10.
Answer:
39
Step-by-step explanation:
f(x)=17x
f(3)=17(3)
f(x)=51
g(x)=4x
g(3)=4(3)
g(x)=12
f(x)-g(x)
51-12= 39
