The correct answer for the question that is being presented above is this one: "(1) <span>For all real numbers a and b, a + b = b+ a; </span>(2) For all real numbers a and b, ab = ba; (3) <span>For all real numbers a, b and c, (a + b) + c = a + (b + c); (4) </span><span>For all real numbers a, b and c, a (b + c) = ab + ac." </span>
Answer:
x=22.5
Step-by-step explanation:
90=4x
x=22.5
Hope this helps!
Remember
(x^m)^n=x^(mn)
and
![x^{m/n}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7Bm%2Fn%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
(m^(2/3))^(1/2)=m^(2/6)=m^(1/3)
m^(1/3)=∛m
last one (rightmost)
A. The ratio of cups of sugar to butter is 3/4 : 1/8. Then multiply both ratios by 8.
8 x 3/4 = 6,
8 x 1/8 = 1.
3/4 : 1/8 is equal to 6 : 1. Therefore, 6 cups of sugar needed when there is 1 cup of butter.
