Answer:
The answer to your question is:
Fraction he has review = 17/36
Fraction he have to study = 19/36
Step-by-step explanation:
Data
Monday studied = 2/9
Tuesday = 1/4
Fraction he has review = ?
Fraction he has left = ?
Process
As the denominator is 9, consider the whole is 9.
Then: Fraction left on Monday = 9/9 - 2/9
= 7 / 9
Fraction left on Tuesday = 7/9 - 1/4
= (28 - 9) / 36
= 19 / 36
Fraction he has review = 17/36
Fraction he have to study = 19/36
The width of the river = 60m and so Zachary will be able to swim the river without getting tired.
<h3>What is Proportion ?</h3>
When two ratios are equal , the ratio are said to be in proportion.
As given in the question ,
the width of the river has to be determined
Looking at the figure , the triangle formed at the side of the river is a right triangle the hypotenuse will be determined from the Pythagoras theorem
20² +24² = y²
y = 21.2 m
As the corresponding sides are proportional
31.2 : z = 20:50
z = 78.1
The value of the width of the river will be determined by the Pythagoras Theorem
78.1² = 50² + x²
x = 60m
the width of the river = 60m
Therefore Zachary will be able to swim the river without getting tired.

The first table!
for every constant change in x, there is a constant change in y (as x increases by 1, y increases by 4)
Answer: Z> -17
z/2+26=17.5
We move all terms containing z to the left and all other terms to the right.
+ 0.5z=+17.5-26
We simplify left and right side of the equation.
+ 0.5z=-8.5
We divide both sides of the equation by 0.5 to get z.
z=-17
