The difference of five and one-tenth, and half of a number is one and six-tenths. What is the number?

mario62 [17]

The number is 7 if the difference of five and one-tenth, and half of a number is one and six-tenths.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The difference between five and one-tenth, and half of a number is one and six-tenths.

Let x be the number:

= 5 1/10 - x/2 = 1 6/10

= 51/10 - x/2 = 16/10

x/2 = 51/10 - 16/10

x/2 = (51-16)/10

x/2 = 35/10

x = 7

Thus, the number is 7 if the difference of five and one-tenth, and half of a number is one and six-tenths.

A student makes a $10.50 purchase at the bookstore with a $20 bill. The store has no bills and gives the change in quarters an

Leviafan [203]

Answer: he collected 22 quarters and 8 fifty-cent pieces

Step-by-step explanation:

Given;

The total amount of money he is to collect is;

A = 20 - 10.50 = $9.50

Let x represent the number of quarter he collected.

Then the number of fifty-cent pieces he collected will be; 30-x

Therefore we can represent it with the equation below;

0.25x + 0.50(30-x) = 9.50

0.25x + 15 - 0.50x = 9.50

0.25x = 15-9.50

x = (15-9.50)/0.25

x = 5.50/0.25

x = 22

The number of fifty-cent is equal to;

30-x = 30-22 = 8

Therefore, he collected 22 quarters and 8 fifty-cent pieces

Dont answer this PLEAS

pickupchik [31]

Answer:

why? also the answer is 1.6y+y-4/15y+7/6y=21/3

We move all terms to the left:

1.6y+y-4/15y+7/6y-(21/3)=0

Domain of the equation: 15y!=0

y!=0/15

y!=0

y∈R

Domain of the equation: 6y!=0

y!=0/6

y!=0

y∈R
