Which story problem could be solved using the given equation?

Answer:

Parenthesis

Exponents

Multiplication (from left to right)

Division (from left to right)

Addition (from left to right)

Subtraction (from left to right)

Step-by-step explanation:

The PEMDAS rule helps you from arriving at the wrong answer if you mix up the order of parentheses, exponents, multiplication and division, and addition and subtraction.

Answer:

It is the order in which you perform operations

first P. (parentheses)

then E. (exponents)

then M. (multiplication)

then D. (division)

then A. (addition)

and last S. (subtraction)

Step-by-step explanation:

These operations must be performed in the correct order or the answer will be incorrect.

Answer:

1) x= -3

  y= 4

2)

  x= 1

  y= -4

Step-by-step explanation:

1)

-4x+3(3x+13)=24

-4x+9x+39=24

5x+39=24

   -39.  -39

5x=-15

/5.    /5

x= -3

Now fill in X to find y

y=3(-3)+13

y=-9+13

y=4

2)

-4x+3(3x-7)=-16

-4x+9x-21= -16

5x-21 = -16

   +21.   +21

5x=5

/5. /5

x=1

3(1)-7=y

3-7=y

-4=y

Answer:

y = 120

Step-by-step explanation:

If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.

Answer:

120

Step-by-step explanation:

set up a proportion: 80/10=y/15

solve: 80*15=10y

1200=10y

y=120

4/8, and 2/8

Step-by-step explanation:

Step-by-step explanation:

Convert the following decimals into percentages:

0.004 * 100 = 0.4%

0.26 * 100 = 26%

0.58 * 100 = 58%

Answer:

45 ∘,45 ∘ ,90 ∘

Step-by-step explanation:

Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘

. let the other two angles be x

Thus, sum of angles = 180

90+x+x=180

2x=90

x = 45 ∘

The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘

Answer:

Marc: 8 meters & 4 seconds

Prisha: 6 meters & 3 seconds

Step-by-step explanation:

Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s

Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s

To find speed we simply have to divide distance by time

The way that I figure out the answer was by trial and error. This is when we have to get random numbers and try them.

2 seemed a reasonable answer as it couldn't a number such as 5 as there is only 1 factor of 5 between 0 and 9. There are 4 factors of 2 between 0 and 9

Hope this helps, have a great day!!

The correct answer is y = -2x.

Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by  [tex]\alpha[/tex] .  

Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,

                                          a  [tex]\alpha[/tex]  b

                                 =>    [tex]a/b = k[/tex] ( where k is constant)

                                 =>     [tex]a = kb[/tex] [tex]--- >[/tex] 1

Substitute a=x and b=y in 1, and then we get

                                          [tex]x = ky[/tex]

Therefore, the general form of an equation which satisfies direct proportion is x = ky.

[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex]  are not in the form of [tex]x = ky[/tex].

So, The equation of direct proportion is y = -2x.
