Answer:
77
Step-by-step explanation:
For each 2 evergreens there are 7 other trees.
Add 2 +7 = 9.
For each 7 non-evergreens there are 9 trees of all types.
The ratio of non-evergreens to total trees is 7/9.
Let x = number of non-evergreens.
7/9 = x/99
9x = 7 * 99
Divide both sides by 9.
x = 7 * 11
x = 77
The required estimation of 11 4/5 divided by 3 1/5 is 4.61.
Given that,
To determine the estimation of 11 4/5 divided by 3 1/5.
<h3>What is arithmetic?</h3>
In mathematics, it deals with numbers of operations according to the statements.
In the given question we have given, 2 mixed fractions we have to determine the simplified fraction by dividing one from the other, as stated in the question.
Simplification,
11 + 4 / 5 = 59 / 4
3 + 1 / 5 = 16 / 5
11 4/5 divided by 3 1/5 estimation,
= ( 59/4 ) / (16 / 5)
= 59 * 5 / 4 * 16
= 4.61
Thus, the required estimation of 11 4/5 divided by 3 1/5 is 4.61.

Answer:
No solution
Step-by-step explanation:
y=x-1 and y-x=-9
1st make sure both equations are in slope intercept form
since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so
y-x=-9
+× +×
y=×-9
now you have y=x-1 and y=x-9
substitute the y with the other equation
x-1=x-9
subtract x from both sides since you can't have the variable on both sides
now you've got -1 = -9
and since that equation isn't true, it has no solution.
Answer:
See below.
Step-by-step explanation:
40 + 15x = 30 + 19x
15x - 19x = 30 - 40
-4x = -10
x = 2.5
Two and a half hours.
