Answer:

Step-by-step explanation:

1) [tex]\frac{1}{3}-(\frac{1}{3}*\frac{1}{3}) + (\frac{1}{3}[/tex] ÷[tex]\frac{1}{3}) =[/tex] [tex]\frac{1}{3}-\frac{1}{9} +(\frac{1}{3}*\frac{3}{1})[/tex]

                                  [tex]=\frac{1}{3}-\frac{1}{9}+1\\\\=\frac{1*3}{3*3}-\frac{1}{9}+\frac{1*9}{1*9}\\\\=\frac{3}{9}-\frac{1}{9}+\frac{9}{9}\\\\=\frac{3-1+9}{9}\\\\=\frac{11}{9}\\\\=1\frac{2}{9}\\[/tex]

2)

 [tex](3\frac{3}{4}-2\frac{2}{3})*1\frac{1}{2}=(\frac{15}{4}-\frac{8}{3})*\frac{3}{2}\\\\=(\frac{15*3}{4*3}-\frac{8*4}{3*4})*\frac{3}{2}\\\\=(\frac{45}{12}-\frac{24}{12})*\frac{3}{2}\\\\=(\frac{45-24}{12})*\frac{3}{2}\\\\=\frac{21}{12}*\frac{3}{2}\\\\=\frac{21}{4}*\frac{1}{2}\\\\=\frac{21}{8}\\\\=2\frac{5}{8}[/tex]

3) When finding equivalent fractions both numerator and denominator should be multiplied with the same number. But  Lethna didn't multiply with the numerator.

[tex]\frac{2}{5}+\frac{1}{2}=\frac{2*2}{5*2}+\frac{1*5}{2*5}\\\\=\frac{4}{10}+\frac{5}{10}\\\\=\frac{9}{10}[/tex]

4) In fraction multiplication convert mixed fraction to improper fraction and reduce to smallest term

[tex]1\frac{1}{2}*5\frac{1}{3}=\frac{3}{2}*\frac{16}{3}\\\\=8[/tex]

5)

[tex]8\frac{2}{3}*5\frac{4}{9}=\frac{26}{3}*\frac{49}{9}\\\\=\frac{1274}{27}\\\\= 47\frac{5}{27}\\\\[/tex]

6) Use Keep Change Flip (KCF) method for fraction division

[tex]4\frac{2}{5}[/tex] ÷ [tex]6\frac{5}{8}[/tex] = [tex]\frac{22}{5}[/tex] ÷ [tex]\frac{53}{8}[/tex]

          [tex]= \frac{22}{5}*\frac{8}{53}\\\\=\frac{176}{265}[/tex]

Answer:

I think 70 but not sure

Step-by-step explanation:

sorry if its wrong

Answer:

70

Step-by-step explanation:

x + 80 + 30 = 180     {Angle sum property}

   x + 110 = 180

          x = 180 - 110

          x = 70

Answer:

IQ scores and GPAs are positively correlated with a strong relationship. Similarly, IQ and SAT scores are positively correlated with a strong relationship. Because the variable IQ is in both sets, there is likely to be a relationship between the other two variables, GPAs and SAT scores.

Answer:

-1/3

Step-by-step explanation:

To find the slope, we can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 9-10)/(10-7)

    = -1/3

Answer:

-1/3

Step-by-step explanation:

The slope formula is [ y2-y1/x2-x1 ].

9-10/10-7

-1/3

Answer:

a) y = 0.55x + 75

b) $108

Step-by-step explanation:

a) to find the equation represent the sequence use the y=mx+b formula

y = total price

m = cost per mile

x = miles driven

b = flat fee

Therefore y = 0.55x+75

b) To figure out the cost of driving 60 miles you use the equation y = 0.55x + 75

y = 0.55 X 60 + 75

= 108

Therefore the cost of renting the truck and driving 60 miles is $108

Answer: the slope intercept form of 2x+y=6 is y=-2+6

Step-by-step explanation:

2x+y=6  (subtract 2x from both sides)

-2x    -2x  (the -2x and the 2x cancel leaving...)

y=-2x+6  →( y equals negative two x plus six)

Answer:

b)=(4,8) (2,6)

a)3,8 2,5

Answer:

t=12.5s

Step-by-step explanation:

s(t) = 50t - 2t^2

v(t) = 50 - 4t

a(t) = -4

When v(t) = 0, the car stops.

v = u +at

0 = 50 + (-4)t

t = 12.5

Answer:

a) 19 batches

b) $0.18

Step-by-step explanation:

A 4-pound bag of sugar contains 4 54 one-teaspoon servings and costs $3.49. A batch of muffins uses 1/2 cup of sugar.

1 cup = 48 teaspoons

a) How many whole batches can you make if you use as much of the sugar as possible?

1 batch = 1/2 cups of sugar = 24 teaspoons of sugar

Hence,

24 teaspoons of sugar = 1 batch

454 one-teaspoon servings = x

Cross Multiply

24 × x = 1 × 454

x = 454/24

x = 18.9166666667

Approximately to whole batches = 19 batches

b) What is the cost of sugar for each batch?

454 one-teaspoon servings and costs $3.49 = 19 batches

Hence

19 batches = $3.49

1 batch = x

x= $3.49/19

x = $0.18368421052

Approximately = $0.18

Answer:

[tex]\frac{0}{4} x[/tex]

Step-by-step explanation:

We can use the equation: [tex]\frac{-4}{-4} \frac{-(-4)}{-(-8)}[/tex]

After solving, we get [tex]\frac{0}{4} x[/tex].

This means that the equation of the line is y = -4. This is a horizontal line moving infinitely in both directions with a constant y-value of -4.

Answer:

To distribute means to divide something or give a share or part of something. For example, for the problem 4(6+2), you would use the distributive property and distribute the 4. Making the end result, 24+8.

Answer:

The distributive property tells us how to solve equations in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. Normally when we see an equation like this … 4(8+3) distributive property format 4(8+3) -> 4(11) -> 44 we just evaluate what’s in the parentheses first, then solve it: 4(8+3)=4x8 + 4x3=44 These are the 2 methods

Point (-2, 0)

Point (1, 2)

Step 2: Find slope m

Answer:

x= -3

y= -2

From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.

Answer:

36.33 its not correct

Step-by-step explanation:

but if its correct thank me ;)

Answer:

1) The equation that has infinitely many solution is y = -8/11·x + 4

2) The equation of the graph that has no solution is y = -8/11·x + 1

3) The equation of the line that has only one solution is y  = -1/4·x + 2

Step-by-step explanation:

1) The points on the graph are;

(0, 4), and (5.5, 0)

The slope of the line defined by the given two points, we have;

(0 - 4)/(5.5 - 0) = -40/55 = -8/11

The equation of the straight line graph in point and slope form, we have;

y - 4 = -8/11 × (x - 0)

y - 4 = -8/11·x

For the equation for the system that has infinitely many solution, we have;

y = -8/11·x + 4

2) For the equation whose graph foes through the point (0, 1) and the system has no solution, we have;

An equation that has no solution with the equation y = -8/11·x + 4, is parallel to y = -8/11·x + 4, and therefore, the slope are equal

Therefore, the equation whose graph foes through the point (0, 1) and the system has no solution, in point and slope form is given as follows;

y - 1 = -8/11 × (x - 0)

y - 1 = -8/11·x

The equation of the graph that has no solution is therefore;

y = -8/11·x + 1

3) For the equation of the graph that goes through the point (0, 2), and has a common solution with the system at (4, 1), we have;

The slope of the graph is (1 - 2)/(4 - 0) = -1/4

The equation of the line that has only one solution with the system in point and slope form is given as follows;

y - 2 = -1/4×(x - 0)

y - 2 = -1/4·x

The equation of the line that has only one solution in standard form is therefore;

y  = -1/4·x + 2
