Change 2.6 from decimal to fractions show explanation
noname [10]

Answer:

Step-by-step explanation:

The 2 in 2.6 is in the ones place so we know that it equals 200. The 6 in 2.6 is in the tenths place so we know that it equals 60.  Add 200 with 60 to get 260/10. The denominator is 10 because 2.6 only extends to the tenths place.

ms. jeffers is splitting $775 among her three sons. of the oldest gets twice as much as the youngest and the middle son gets $35
Angelina_Jolie [31]

The oldest son will get $370, the middle will get $220 and the youngest will get $185.

Step-by-step explanation:

Given,

Total amount to be split = $775

Let,

Oldest son's share = x

Middle son's share = y

Youngest son's share = z

According to given statement;

x+y+z=775     Eqn 1

the oldest gets twice as much as the youngest

x = 2z             Eqn 2

the middle son gets $35 more than the youngest

y = z+35         Eqn 3

Putting value of x and y from Eqn 2 and 3 in Eqn 1

2z+(z+35)+z=775\\2z+z+35+z=775\\4z=775-35\\4z=740\\

Dividing both sides by 4

\frac{4z}{4}=\frac{740}{4}\\z=185

Putting z=185 in Eqn 2

x=2(185)\\x=370

Putting z=185 in Eqn 3

y=185+35\\y=220

The oldest son will get $370, the middle will get $220 and the youngest will get $185.

PLEASE HURRY
Inga [223]
The points: (0,4), (1,8),(2,10) is NOT a linear function as it doesnt pass the verticle line test. Linear function should always be in a straight line. Examples of linear functions: 4x + 3y = 6. Examples of nonlinear functions: y = 8x^2 + 10.
