Clara simplifies (8 b minus 4 r) minus (2 b minus r) and says the result is 6 b minus 5 r. What error did Clara make?

Answers

Answer: Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.

Step-by-step explanation: (8b-4r)-(2b-r)

Open the bracket

=8b-4r-2b+r

Collect the like terms and simplify

=8b-2b-4r+r

=6b-3r

Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.

Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she has $4.05 how many nickels and dimes does laura

Answers

Answer:

Number of dimes = 34

Number of nickels = 13

Step-by-step explanation:

Total number of coins = 47

Coins are in the form of nickels and dimes.

Value of a nickel = 5 cents

Value of a dime = 10 cents

Total value of coins = $4.05 or 405 cents

To find:

Number of nickels and dimes?

Solution:

Let number of nickels = [tex]x[/tex]

Money value of nickels = 5[tex]x[/tex]

Let number of dimes = [tex]y[/tex]

Money value of dimes = 10[tex]y[/tex]

Total value of coins = [tex]5x+10y[/tex]

This value is given as equal as 405.

As per question statement, the equations can be written as:

[tex]5x+10y = 405 ..... (1)\\x+ y = 47 ...... (2)[/tex]

Multiplying equation (2) with 5 and subtracting from equation (1):

[tex]10y - 5y = 405 - 235 \\\Rightarrow 5y = 170\\\Rightarrow y = 34[/tex]

Number of dimes = 34

Number of nickels  = 47 - 34 = 13

Answers

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

  = 26 - 4

  = 22

For x = 2,

y = 26 - 4(2)

  = 26 - 8

  = 18

For x = 3,

y = 26 - 4(3)

  = 26 - 12

  = 14

For x = 6,

y = 26 - 4(6)

  = 26 - 24

  = 2

Therefore, table for the function will be,

x               y

Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A?
PLZ HELP

Answers

Answer:

sail a = 81ft²

sail b base = 12ft

Step-by-step explanation:

question 5:

the measurements for sail A are 18ft(height) and 9ft (base)

the formula to find the the area of a triangle is (b · h) 1/2

(9 · 18) 1/2 = (162) 1/2 = 81

so ahmad will need 81ft² of fabric for sail a

question 6:

we know that the formula to find the area of a triangle is  (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.  

(b · 18) 1/2 = 108

[tex]\frac{(b . 18) 1/2}{1/2}[/tex] = 108/ 1/2

(b · 18) = 216

18b  = 216

18b/18 = 216/18

b= 12

check your work:

(12 · 18) 1/2 = 108

(216) 1/2 = 108

108 = 108  true!

the base measurement for sail b is 12ft
