1.30 × 3 = 3.90

3.90 + 0.65 (half of 1.30) = 4.55

the most 104 can be devided by 4.55 with no remainders is 22

22 × 4.55 = 100.1

this leaves with 3.9$ which we can buy 3, 1.30 with

22 + 3 = 24

25 tarts is the most you can buy with 104$ leaving on remainders.

What is 56 divided by 3 1/2

Anton [14]

Answer:

Step-by-step explanation:

First you will need to change both of the numbers into improper fractions:

56/1 ÷ 7/2

Then do keep change flip. What that means is keep the first fraction the same, change the division symbol into a multiplication symbol, and flip the second fraction:

56/1 x 2/7

Then just multiply the two numerators by each other and the two denominators by each other:

56 x 2 = 112

7 x 1 = 7

112/7 would be the answer.

Graph the linear equation: - x + 3y = 5

yKpoI14uk [10]

its easiest if you put it in y = mx + b form, where b is the number you plot on the y axis and m is your slope.
rearranging...
x + 3y = -5 3y = -x - 5 y = -1/3 x - 5/3
so your b value is -5/3, which is where you'll plot a point on the y axis. the slope is -1/3
since slope is rise over run, [and this case its negative] you'll go down 1 and to the right three.
edit: then draw a point there, connect the points, and you'll have a line =]

The present age of Madison’s mother is 3 times that of Madison. After 614 years, the sum of their age will be 5334 years. Find t

Neporo4naja [7]

The present age of Madison is <u>1027 years</u> and that of his mother is <u>3080 years</u> (rounded off to nearest whole numbers), solved using the linear equation in one variable: <u>(x + 614) + (3x + 614) = 5334</u>, where x represents the present age of Madison.

<h3>What are linear equations in one variable?</h3>

Linear equations in one variable are the linear relationship between two algebraic expressions not involving more than one variable throughout the equation.

<h3>How to solve the question?</h3>

In the question, we are informed that the present age of Maison's mother is 3 times that of Madison. After 614 years, the sum of their age will be 5334 years.

We are asked to determine their present ages.

We assume the present age of Madison to be x years.

Therefore, the present age of Madison's mother = 3x years {3 times that of Madison}.

Now, after 614 years, both of their ages will increase by 614 years.

Therefore, age of Madison after 614 years = x + 614 {Present + 614}.

Age of Madison's mother = 3x + 614 {Present + 614}.

We are given that after 614 years, the sum of their ages will be 5334.

This can be represented by the linear equation in one variable:

(x + 614) + (3x + 614) = 5334

This linear equation in one variable can be simplified and solved in the following way:

or, 4x + 1228 = 5334 {Simplifying},

or, 4x + 1228 - 1228 = 5334 - 1228 {Subtracting 1228 from both sides}
