Simplify the expression:

2/3y+5-3-11/12y

Thanks!

Answer:

It would be positive

Step-by-step explanation:

To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive

Answer:

positive

Step-by-step explanation:

-9/16= -0.5625

9/8= 1.125

-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)

              =0.5625

  the reason

             + * + = +

              - * - = +                                              

              + * - = -

              +/+ =+

              - / - = -

              -/ + = -

              + / - = -

Answer:

A) x=9

Step-by-step explanation:

48-12=36.

36/4=9

More detailed explanation:

4x+12=48

    -12    -12

     4x = 36

     /4     /4

     x   =    9

The solution of the equation is, x = 9.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The equation is,

⇒ 4x + 12 = 48

Now, We can solve the equation for value of x as;

⇒ 4x + 12 = 48

Subtract 12 both side, we get;

⇒ 4x + 12 - 12 = 48 - 12

⇒ 4x = 36

Divide by 4;

⇒ 4x/4 = 36/4

⇒ x = 9

Answer:

3/16

Step-by-step explanation:

so since there isnt a half of 3/8 we would multiply the number x2 so the number is 6/16 and half of that is 3/16 becuase 6 can be split in half

Answer:

30

Step-by-step explanation:

= -1/4 + 17 + (4/5)+ 1/4 + 13 + (-4/5)  <-- Cancel out 1/4 to -1/4 and 4/5 to -4/5

= 17 + 13

= 30

Answer:

[tex]\displaystyle -0.\overline{37}=-\frac{37}{99}[/tex]

Step-by-step explanation:

Convert a Repeating Decimal to a Fraction

We need to convert the following decimal to a fraction:

[tex]-0.\overline{37}[/tex]

Let's call x to the given number:

[tex]x=-0.\overline{37}[/tex]

The number has two repeating (periodic) decimals, thus we multiply by 100:

[tex]100x=-37.\overline{37}[/tex]

Note the decimals continue to repeat exactly like the original number.

Subtracting both expressións, the repeating decimals are simplified:

[tex]100x - x = -37[/tex]

Operating:

99x=-37

Dividing by 99:

[tex]\displaystyle x=-\frac{37}{99}[/tex]

The fraction cannot be simplified, thus:

[tex]\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}[/tex]

Answer:

the value of x is 10

Step-by-step explanation:

The new length is 35+10=45 and the new width is 18+10=28.

Area of rectangle is length times of breadth.

Given that enclosure at the zoo is 35 feet long by 18 feet wide. It means length is 35 feet and width is 18 feet.

Area of Rectangle=Length × Width

=35×18

=630

The zoo wants to double the area of the enclosure by adding the same distance x to the length and width.

(35+x)×(18+x)=1260

630+35x+18x+x2=1260

x2+53x+630-1260=0

x2+53x-630

Now use the quadratic formula we get

x=10.

The new length is 35+10=45

The new width is 18+10=28.

Hence the new length is 35+10=45 and the new width is 18+10=28.

Answer:

is it multiple choice?

she will have $2065 in her savings account after the 25th week.

Answer:

2,065

Step-by-step explanation:

First you need to figure out 65 times 25 because she puts $65 into her account every week so you need to multiply by 25 because you have to figure out how much money she will have on the 25th week so:

$65 * 25 = 1,625

then you need to add that to 440 because ahe still only has 440 in her account until now so, in conclusion, she has 2,065 because:

$65 * 25 = $1,625 + $440 = 2,065

I hope this helped! I am not very good at explaining.

Answer:

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Answer:A rule for a function can be written by analyzing a graph. Using slope-intercept form, standard form, and point-slope form, functions can be written from a given graph.

To write a function in slope-intercept form given a graph, determine the slope and y-intercept of the graph and then substitute these values into the formula y = mx + b. If it is not possible to determine the y-intercept from the graph, determine a different point, substitute it into the equation and solve for b.

Example Find the function rule for the graph using the slope-intercept form.Step 1. Choose any two points to find slope. (-3, 1) & (3, -3) Find the value of the y-intercept.Step 3. Substitute the m and b values into y = mx + b to create the function rule.
