Need help plz!!!!!!!

Answer: See explanation

Step-by-step explanation:

A. 7(s + c)

= 7s + 7c

B. The cost of a science fiction novel is $5.99 and the cost of a comic book is $6.49. Sales tax is 6%. The total amount that Julio spent at the bookstore would be calculated as:

= 7s + 7c

= 7($5.99) + 7($6.49)

= $41.93 + $45.43

= $87.36

We then add tax which will then be:

= $87.36 + (6% × $87.36)

= $87.36 + (0.06 × $87.36)

= $87.36 + $5.24

= $92.60

Answer:

Step-by-step explanation:

Let x be the total number of medals won by the Russians.

The way to do this is to add the ratios together

1 + 8 + 5 = 14

(5/14) x = 25

Multiply by 14

5*x = 25 * 14

5x = 350              

divide by 5

70

8/14 = x / 70

14x = 8 * 70

14x = 560

x = 560 / 14

x = 40

The USA won 40 medals.

1/14 = x / 70

14x = 70

x = 5

Canada Won 5 medals.

Check

Russia       Won 25 medals

Canada     Won   5 medals

USA           Won 40 medals

Total 70

Answer:

YES

Step-by-step explanation:

the dimensions of the poster board has to be converted to inches to add comparability

1 feet = 12 inches

3 x 12 = 36 inches

width = 2 x 12 = 24 inches

Area = length x breadth

36 x 24 = 864 cm^2

area of sticker = 2 x 2 = 4cm^2

Number of stickers that can be put on the board = 864 / 4 = 216

216 is greater than 100. So the board has enough room for the stickers

Answer: X is equal to -3

Step-by-step explanation: I isolated x and then divided both sides by x

Answer:

Ok so its -3;3

here you go

Answer: The y-intercept is found by substituting known values for x and y in the equation and solving for b. the known values are (x,y) = (2,8.4) Equation of y = 4.2*x + b becomes 8.4 = 4.2*2 + b

Answer:

D. 48

Step-by-step explanation:

In the experiment, 16/40 landed exactly on heads. If you do 16/40 * 3/3 = 48/120.

This means that you can estimate 48 of the next 120 trials have 2 coins showing heads.

Step-by-step explanation:

Find the Least Common Multiple

     The left denominator is :       4

     The right denominator is :       6

       Number of times each prime factor

       appears in the factorization of:

Prime

Factor   Left

Denominator   Right

Denominator   L.C.M = Max

{Left,Right}

2 2 1 2

3 0 1 1

Product of all

Prime Factors  4 6 12

Least Common Multiple:

    12

Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Denominator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 3

  Right_M = L.C.M / R_Deno = 2

Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction, multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      9 • 3

  ——————————————————  =   —————

        L.C.M              12  

  R. Mult. • R. Num.      17 • 2

  ——————————————————  =   ——————

        L.C.M               12  

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

9 • 3 - (17 • 2)      -7

—————— =   ——

       12                 12

Step-by-step explanation:

she might lose 1/4 of the next free throws

Given:

Consider the given square is

[tex](2xy+5y)^2[/tex]

To find:

The value of given square by using the identities.

Solution:

We know that,

[tex](a+b)^2=a^2+2ab+b^2[/tex]            ...(i)

We have,

[tex](2xy+5y)^2[/tex]

Using the identity (i), we get

[tex](2xy+5y)^2=(2xy)^2+2(2xy)(5y)+(5y)^2[/tex]

[tex](2xy+5y)^2=4x^2y^2+20xy^2+25y^2[/tex]

Therefore, the value of given square expression is [tex]4x^2y^2+20xy^2+25y^2[/tex].

My guess is % 1/400

Answer:

0.5 is 0.25% of 200.

Step-by-step explanation:

1 is 1/200 of 200.

Therefore, 0.5 is 1/400 of 200.

1/400 = 0.0025 = 0.25/100

Therefore, 0.5 is 0.25% of 200.

Answer:

56

Step-by-step explanation:

2a^2b+5ab-4

substitute a & b:

2(-4)^2(5)+5(-4)(5)-4

2(16)(5)+5(-4)(5)-4

160-100-4=56

Answer:

3--1/-2-4=4/-6=2/-3

y=-2/3x+b

-2*-2/3=4/3

3-4/3=5/3

y=-2/3x+5/3

Step-by-step explanation:

Answer:

[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Step-by-step explanation:

We want to find the equation of the line that passes through the two points:

(4, -1) and (-2, 3).

First, we will find the slope of the two points. So:

[tex]\displaystyle m=\frac{3-(-1)}{-2-4}=\frac{4}{-6}=-\frac{2}{3}[/tex]

Now, we will use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

Use either point. I'm going to use (4, -1). So, substitute:

[tex]\displaystyle y-(-1)=-\frac{2}{3}(x-(4))[/tex]

Simplify and distribute:

[tex]\displaystyle y+1=-\frac{2}{3}x+\frac{8}{3}[/tex]

Subtract 1 from both sides. Therefore:

[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]
