Step-by-step explanation:
Nikki is building a wall with bricks. Each brick is 10 inches long. The bricks are laid end-to-end, and one inch of mortar is layered between each brick.
a. Write and equation to model the number of bricks, N, Nikki needs in each layer to build a wall 10 feet long.
b. Solve the equation and state your result in words.
Answers
Answer:
b = 11
11 bricks will be required with 10 (1 inch motar) in between the bricks.
Step-by-step explanation:
Given the following :
Length of brick = 10 inches long
Between each laid brick, there is an inch of mortar layered before the next brick.
Number of bricks needed to build a wall which is 10 feets long.
Converting from feet to inch :
1 foot = 12 inches
Hence,
10 feets = (10 × 12) = 120 inches (length of wall).
Hence number of bricks needed in each layer :
Total length of b, bricks = length per brick × b = 10b
Since mortar is laid in between any two bricks, then length of mortar for b, number of bricks will be (b-1) inches
Since the total length of wall to be constructed is 120 inches ;
Then the equation required =
Sum of brick length + mortar = 120 inches
10 b + (b - 1) = 120
11b - 1 = 120
Hence,
11b = 120 + 1
11b = 121
b = 121 / 11
b = 11
Number of mortar = (b - 1) = - 11 - 1 = 10
Hence, 11 bricks will be required with 10 (1 inch motar) in between the bricks.
Can you please solve this as soon as you can? Thank you!

I know the answer is .78, but don’t understand why? .9-.6X.2
Answers
It may be confusing because the decimals aren’t like whole numbers.
Step-by-step explanation:
When you multiply 0.6 and 0.2, you do not get 1.2. Rather, the product would be 0.12.
We have the equation [tex]0.9-(0.6)(0.2)[/tex]
To show you what is happening, lets convert these numbers into fractions
This would give us [tex]\frac{9}{10} -(\frac{6}{10})(\frac{2}{10})[/tex]
Recall that when you multiply two fractions, you multiply the numerators and denominators separately. Doing so gives us
[tex]\frac{9}{10} -\frac{6*2}{10*10}[/tex]
Which then becomes
[tex]\frac{9}{10} -\frac{12}{100}[/tex]
The last thing we need to do is to create a common denominator
[tex]\frac{90}{100}-\frac{12}{100}=\frac{78}{100} =0.78[/tex]
Another way to see what is happening is by thinking about the numbers in scientific notation. Doing so would give us
[tex]9*10^{-1}-(6*10^{-1})(2*10^{-1})[/tex]
Once we multiply these terms, we get
[tex]9*10^{-1}-6*10^{-1}*2*10^{-1}\\\\9*10^{-1}-12*10^{-2}[/tex]
Now we can convert these numbers into decimals to get
[tex]0.9-0.12=0.78[/tex]

Answer:
[tex]x=\frac{-3d-9}{k-d}[/tex]
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d
[tex]x=\frac{-3d-9}{k-d}[/tex]
Answer:
Step-by-step explanation:
Step 1: Write out equation
d(-3 + x) = kx + 9
Step 2: Distribute
-3d + dx = kx + 9
Step 3: Subtract dx on both sides
-3d = kx - dx + 9
Step 4: Subtract 9 on both sides
-3d - 9 = kx - dx
Step 5: Factor
-3d - 9 = x(k - d)
Step 6: Divide both sides by k - d

What is the solution to
-(6x+8)= 4(17 – x)?
Answers
Answer:
x=30
Step-by-step explanation:
Simplifying
6x + 8 = 4(x + 17)
Reorder the terms:
8 + 6x = 4(x + 17)
Reorder the terms:
8 + 6x = 4(17 + x)
8 + 6x = (17 * 4 + x * 4)
8 + 6x = (68 + 4x)
Solving
8 + 6x = 68 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
8 + 6x + -4x = 68 + 4x + -4x
Combine like terms: 6x + -4x = 2x
8 + 2x = 68 + 4x + -4x
Combine like terms: 4x + -4x = 0
8 + 2x = 68 + 0
8 + 2x = 68
Add '-8' to each side of the equation.
8 + -8 + 2x = 68 + -8
Combine like terms: 8 + -8 = 0
0 + 2x = 68 + -8
2x = 68 + -8
Combine like terms: 68 + -8 = 60
2x = 60
Divide each side by '2'.
x = 30
Simplifying
x = 30
-(6x+8)= 4(17 – x)? Is x=30

subtract 6 from both sides that gives you your equation that you can work with.
3x+21= -15
then subtract 21 from both sides that gives you

Simplify 4x + 5y - 13xy - x - 2y
Answers
Move the numbers so that the ones with the same variable can be together :> ( examples of variables: x,y,xy)
4x - x + 5y - 2y - 13xy
You can only do the math if the those numbers are the same example: 4x - x = 3x they both have variable so u can subtract them ( remember x = 1x a variable by itself has a invisible 1 next to it). 5y - 2y = 3y.
-13xy is the only one with the variable xy so we gotta just leave it alone
This leads to our answer:
3x + 3y - 13xy

(a) 1.8 kg : 600 grams
(b)
1 hour 20 minutes : 30 minutes
Answers
Answer:
a) 3 :1
b)8 : 3
Step-by-step explanation:
When finding ratio's, both should be in same units.
1.8 kg = 1.8 * 1000
= 1800.0 grams
1.8 : 600 = 1800 : 600 = 18 : 6
= 3 : 1
b) 1 hour 20 minutes = 60 + 20 = 80 minutes
1 hour 20 minutes : 30 minutes = 80 : 30
= 8 : 3
Answer:
a. 3grams : 1gram b. 8 minutes : 3 minutes
Step-by-step explanation:
1.8kg is the same as 1800 grams.
1800:600 is the same as 3:1.
1 hour 20 minutes is the same as 80 minutes.
80:30 is the same as 8:3.
