Answer 1

9514 1404 393

Answer:

  weight = 5, 6.5, 7.2, 9, 16

  cost = $2.50, $3.25, $3.60, $4.50, $8.00

Step-by-step explanation:

The first column tells you the cost is ...

  $2.50/(5 lb) = 0.50 $/lb

That is, each bottom number is half the top number, or each top number is double the bottom number.

The table is ...

  weight = 5, 6.5, 7.2, 9, 16

  cost = $2.50, $3.25, $3.60, $4.50, $8.00

Answer:

So all the possible solutions are:

[tex]\bold{523,~400,~379~and,~378.6}[/tex]

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Add 78 to both sides:

[tex]78+78=[/tex] Cancels Out[tex]300+78=378[/tex]

So now we know the real answer, but it ask for all possible answers.

(Means anything larger than 300 when you plug it into x - 78 > 300.)

Numbers that are greater than 378:

  1.)  [tex]377-78=299 > 300[/tex]  (False)

  2.)  [tex]523-78=445>300[/tex]  (True)

  3.)  [tex]0-78=-78>300[/tex]  (False)

  4.)  [tex]-62-78=-140>300[/tex]  (False)

  5.)  [tex]400-78=322>300[/tex]  (True)

  6.)  [tex]379-78=301>300[/tex]  (True)

  7.)  [tex]222-78=144>300[/tex]  (False)

  8.)  [tex]378.6-78=300.6>300[/tex] (True)

Answer:

1 [tex]\frac{14}{15}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4}{5}[/tex] × 2 [tex]\frac{5}{12}[/tex] ← change the mixed number to an improper fraction

= [tex]\frac{4}{5}[/tex] × [tex]\frac{29}{12}[/tex] ( cancel 4 and 12 by 4 )

= [tex]\frac{1}{5}[/tex] × [tex]\frac{29}{3}[/tex]

= [tex]\frac{29}{15}[/tex]

= 1 [tex]\frac{14}{15}[/tex]

4/5x2 5/12=1 7/15
4/5x22/12 turn into improper
Cross multiply turns into
1/5x22/3 then multiply and get
22/15=1 7/15

How can you use the properties of operations to evaluate
this expression?
18 + 4(28)

Answers

Answer:

Well on of the properties states that unless there are parenthesis, you multiply and divide first then you add and subtract. So, first we multiply 28*4 and that leaves use with 112, now if there is no more multiplication, division, or parentheses, and there's not. We can continue all we do is add 18+112 and we get our answer of 130.

Answer: Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.

Answer:

x = 6

Step-by-step explanation:

Given

3x - 11 = - 2x + 19 ( add 2x to both sides )

5x - 11 = 19 ( add 11 to both sides )

5x = 30 ( divide both sides by 5 )

P and Q are points on the line
4x + 2y = 8

Complete the coordinates of
P and Q

P (0,?)

Q(?,0)​

Answers

Answer:

P(0, 4 ), Q(2, 0 )

Step-by-step explanation:

To find P, with an x- coordinate of 0

Substitute x = 0 into the equation and solve for y

4(0) + 2y = 8 , that is

2y = 8 ( divide both sides by 2 )

y = 4

Thus P(0, 4 )

To find Q with a y- coordinate of 0

Substitute y = 0 into the equation and solve for x

4x + 2(0) = 8, that is

4x = 8 ( divide both sides by 4 )

x = 2

Thus Q(2, 0 )

Solve the equation for y.

4x+6y=12

Answer:

your answer when you solve for y will be: y=-2+ 2x/3

The equation can represent as y = 2 - 2x/3 after solving for y if the equation is 6y = 12 - 4x.

What is a linear equation?

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 equation is:

4x+6y=12

To solve for make the subject as y:

6y = 12 - 4x

Divide by 6 on both sides

y = (1/6)[12 - 4x]

After simplification:

y = 2 - 2x/3

Thus, the equation can represent as y = 2 - 2x/3 after solving for y if the equation is 6y = 12 - 4x.
