Compatible numbers are close to actual numbers, but easier to solve.
So instead of: 326 : 44,
we will do: 320 : 40 = 8
And we know that the real result is:
326 : 44 = 7.4
Answer:
B ) 320 divided by 40 is 8.
Answer: 30 ft tall
Step-by-step explanation: X= the height of the tree in feet
27/x = 4.5/5
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall
<span>Let be A =a3b +9a2b2-4ab5, and B=a3b-3a2b2+ab5,so the difference can be defined as A - B =a3b +9a2b2-4ab5 -(a3b-3a2b2+ab5), when there is negative sign in front of the parathesis, all the inside signs must change: that is as follow: A- B= a3b +9a2b2-4ab5 - a3b + 3a2b2 - ab5= a3b-a3b +9a2b2+3a2b2-4ab5- ab5= 12a2b2 -5ab5, the fist term has 2+2=4, as a degree,the second term has 1 +5 =6, so the true answer : The difference is a binomial with a degree of 6</span>
