Answer: 0.1(1000 + 300m)
Use the distributive property: a x (b + c) = a x b + a x c
0.1 x 1000 + 0.1 x 300m
Evaluate both products: 100 + 30m (1)
Note: Multiplying a number by 0.1 is the same as dividing the number by 10.
We need to determine the profit when 50 pieces are sold.
Substitute m with 50 in equation (1).
100+30(50)
Evaluate product: 100 + 1500
Evaluate sum" 1600
Thus the profit is $1600.

Two positive numbers are in the ratio 2 : 3. Find the numbers if (a) their sum is 55 and (b) their product is 384.
say the numbers are "a" and "b", we know that they're in the ratio of 2:3, or namely that
[tex]\stackrel{\textit{in the ratio of 2 to 3}}{a~:~b\qquad \qquad 2:3}\qquad \qquad \implies \qquad \cfrac{a}{b}=\cfrac{2}{3}\implies \cfrac{3a}{2}=b \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{their sum is 55}}{a + b = 55}\implies a + \cfrac{3a}{2}=55\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{2}}{2\left( a + \cfrac{3a}{2} \right)=2(55)} \\\\\\ 2a+3a=110\implies 5a=110\implies a = \cfrac{110}{2}\implies \boxed{a = 22}[/tex]
[tex]\stackrel{\textit{we know that}}{\cfrac{3a}{2}=b}\implies \cfrac{3(22)}{2}=b\implies \boxed{33=b} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{their product is 384}}{ab=384}\implies a\left( \cfrac{3a}{2} \right)=384\implies \cfrac{3a^2}{2}=384\implies 3a^2=768 \\\\\\ a^2=\cfrac{768}{3}\implies a^2=256\implies a=\sqrt{256}\implies \boxed{a=16} \\\\\\ \stackrel{\textit{we know that}}{\cfrac{3a}{2}=b}\implies \cfrac{3(16)}{2}=b\implies \boxed{24=b}[/tex]
The positive numbers for both the parts are obtained as 22,33 and 16,24 respectively.
How to write a linear equation?A linear equation for the given case can be written by assuming any variable as the unknown quantity. Then, as per the given data the required operations are done and it is equated to some value.
(a) As per the question, the numbers can be considered as 2x and 3x respectively.
Then, the equation for their sum can be written as follows,
3x + 2x = 55
⇒ 5x = 55
⇒ x = 11
The numbers are obtained as 2 × 11 = 22 and 3 × 11 = 33.
(b) Similarly, the equation for the product of numbers can be written as,
3x × 2x = 384
⇒ 6x² = 384
⇒ x² = 64
⇒ x = 8
The numbers are obtained as 2× 8 = 16 and 3 × 8 = 24.
The required number for both the cases are 22,33 and 16,24 respectively.

The second side of a triangular deck is 4 feet longer than the shortest side, and the third side is 4 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 52 feet, what are the lengths of the three sides?
Answer:
13 ft, 17 ft, 22 ft
Step-by-step explanation:
let x be the shortest side, then second side is x + 4 and the third side is
2x - 4
sum the 3 sides and equate to 52
x + x + 4 + 2x - 4 = 52 , simplify
4x = 52 ( divide both sides by 4 )
x = 13
x + 4 = 13 + 4 = 17
2x - 4 = 2(13) - 4 = 26 - 4 = 22
lengths of 3 sides are 13 ft, 17 ft and 22 ft

Indira was measuring the length of her school's hallway. The first part of the hallway
was 132 inches long. The next part was 3 yards long. How long is the hallway in
feet?
Answer:
132 in /12 in/ft + 3 yd(3ft/yd) = 11 + 9 = 20 ft
Step-by-step explanation:
Answer:
20 ft
Step-by-step explanation:
12 inches = 1 foot
12 : 1 = 132 : y
[tex]\frac{132:y}{12:1}[/tex]
12 × y = 132 × 1
12y = 132
12y ÷ 12 = 132 ÷ 12
y = 11
11 ft
1 yard = 3 feet
1 : 3 = 3 : y
[tex]\frac{1:3}{3:y}[/tex]
1 × y = 3 × 3
1y = 9
y = 9
9 ft
11 ft + 9ft = 20 ft

Answer:
7
Step-by-step explanation:
42/6= 7
---
its a sort of memorization thing youll know when you do enough of them.
if not, you can divide by smaller parts.
3*2=6 so you can divide 42 by 2, and then 3 if that is easier
42/2
=21
then divide by 3 =7
Answer: 7
Step-by-step explanation: If you simplified 42/6 you would get 7 and 42/6 is basically 42 ÷ 6 which equals 7.
A rectangle has a length of x + 7 and a width of x-2. Which equation below describes the perimeter, P, of
the rectangle in terms of x?
Answer:
P = 4x + 10
Step-by-step explanation:
perimeter of a rectangle = 2( width + length )
P = 2 ( x - 2 + x + 7 )
P = 2 ( x + x + 7 - 2 )
P = 2 ( 2x + 5 )
P = 4x + 10

Express the dollowing fraction in decimal form as a terminating decimal or as a infinite repeating decimal 3/16
Answer:
3/16 as a decimal is equal to 0.1875.
Let's convert the given fraction to a decimal number.
Explanation:
To convert any fraction to decimal form, we just need to divide its numerator by denominator.
Here the fraction is 3/16 which means we need to perform 3 ÷ 16.
So, 3/16 is equal to 0.1875.
