Which statement is true?
Lelu [443]

Answer:

The statement that is true is:

A debt of $17 is a larger value than a debt of $20.

Step-by-step explanation:

Let us look at the statements one after the other to determine if they are true or not:

1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$

2) One half an apple is equivalent to 8 fourths apples:

one half an apple = \frac{1}{2}\ of\ an\ apple

8 fourths of an apple = \frac{8}{4} = \frac{2}{1}\ of\ and\ apple. Therefore, one half of an apple is not equivalent to 8 fourth of an apple.

3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:

8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009

4) \frac{2}{3}\ below\ zero is a lower temperature than 6 below zero:

\frac{2}{3}\ below\ zero\ = (-\frac{2}{3})^\circ

6 below zero = - 6°

On the number line, -6 is smaller than -\frac{2}{3} hence the statement is false.

Grayson buys cheese and lemons at the store.
diamong [38]

Answer:

Equation: 25.81 = 6.55 + 3x

One Bag of Lemons: $6.42

Three Bags of Lemons: 19.26

Step-by-step explanation:

25.81 = 6.55 + 3x

-6.55   -6.55

19.26 = 3x

/3         /3

6.42 = x

Thus, he/she payed $6.42 for each bag of lemons and $19.26 for all three bags of lemons combined.

Solve the linear system by graphing y=x y= 4x -9
Levart [38]

y=x or x=y is very easy to graph.

Choose whatever value of x and use the same for y in the same coordinate. Repeat and strike a line through all the points.

Some examples of valid points would be: (1,1), (2,2), (0,0) and (-1,-1).

Then, to graph y=4x-9 you have to look at it in terms of the equation of a line (y=mx+c) and its parts.

In this case, m=4 and c=-9.

So, you choose any value for x and you solve to find its y counterpart.

I will start with x=0:

x=0\\\\y=4(0)-9\\y=0-9\\y=-9

Now, we have a first coordinate: (0,-9).

Repeat with a different value:

x=5\\\\y=4(5)-9\\y=20-9\\y=11

It gives us the coordinates (5,11).

Plot those into the graph and strike a line through them.

Wherever the two lines in your Cartesian Plane cross, that is the solution for both equations. It should be 3.

You can check it by replacing x and y by "3" in both formulas and equating the values of y:

y=x\\y=4x-9\\\\x=4x-9\\(3)=4(3)-9\\3=12-9\\3=3

Your solution is worked out and checked to be correct.

PS: I am attaching a picture of the graph, so you can have a visual idea of what it should look like.
