Jacques wants to make up packs of $0.45 comic books mixed with $0.75 ones to sell at $9.00 per pack. The number of $0.45 comic books is 4 more than the number of $0.75 comic books. Find the number of each type in the pack.
Answers
Answer:
The number of each type in the pack is 5 of $0.45 comic books and 9 of $0.75 comic books
Step-by-step explanation:
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
In this case, the unknowns or unknown variables are:
x: number of $ 0.45 comic books
y: number of $ 0.75 comic books
Jacques wants to make up packs of $0.45 comic books mixed with $0.75 ones to sell at $9.00 per pack. Then the equation that represents this situation is:
x*0.45 + y*0.75= 9
On the other side, the number of $0.45 comic books is 4 more than the number of $0.75 comic books. Then the equation that represents this situation is:
x+4=y
The system of equations to solve is:
[tex]\left \{ {{x*0.45+y*0.75=9} \atop {x+4=y}} \right.[/tex]
One way to solve a system of equations is the substitution method, which consists of solving one of the unknowns in one of the equations and substituting its value in the next.
In this case we directly replace the expression of the variable and of the second equation in the first:
x*0.45 + (x+4)*0.75= 9
Solving:
x*0.45 + 0.75*x + 4*0.75= 9
1.2*x + 3=9
1.2*x= 9-3
1.2*x= 6
x= 6÷ 1.2
x=5
Replacing this value in the expression x+4=y you get:
5 +4=y
9=y
The number of each type in the pack is 5 of $0.45 comic books and 9 of $0.75 comic books

An 11-m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 14 m. Find the length of the shadow. If necessary,
round your answer to the nearest tenth.
14
11
?
Answers
Answer:
8.66 m
Step-by-step explanation:
Given that,
The distance from the top of the building to the tip of the shadow is 14 m
The height of the building is 11 m.
We need to find the length of the shadow. we can see that the length of the shadow forms the base of the triangle.
The distance from the top of the building to the tip of the shadow form hypotensue and height of the building forms perpendicular. So, we can use Pythagoras theorem to find the base.
So,
[tex]H^2=b^2+h^2\\\\b^2=H^2-h^2\\\\b=\sqrt{14^{2}-11^{2}}\\\\b=8.66\ m[/tex]
So, the length of the shadow is 8.66 m.
There are 2 rectangles. One was 1.2 cm by 3.4 cm. The other was measured 2.1 cm by 1.7 cm. How much is the perimeter?
Answers
Answer: See explanation
Step-by-step explanation:
Perimeter of a rectangle is given as:
= 2(length + breadth)
First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:
= 2(1.2+ 3.4)
= 2(4.6)
= 2 × 4.6
= 9.2cm
Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:
= 2(2.1 + 1.7)
= 2 × 3.8
= 7.6cm
Total perimeter = 9.2cm + 7.6cm = 16.8cm

You are running the concession stand at a volleyball game, selling hot dogs and cans of pop. Each hot dog costs $1.50 and each soda costs $0.50. At the end of the night you have made exactly $78.50. You know that you have sold exactly 87 items, but cannot remember how many of each. That mean PTA lady will never let you work the concession stand again if you don’t report the correct number of each item sold! How many of each did you sell?
Answers
Answer:
Hot Dogs: 35
Soda: 52
Step-by-step explanation:
35 hot dogs + 52 sodas is 87 items.
35 x $1.50 = $52.50
52 x $0.50 = $26.00
$52.50 + $26.00 = $78.50

Mike is a cashier. He works 35 hours and is paid a total of £217
What is Mike's hourly rate of pay? (2 marks)
Your answer
Answers
Answer:
Answer vary :
Mike is paid $6.20 per 1 hour.
Step-by-step explanation:
honestly in my opinion that’s the answer.
‘what is happening is we need to find out how much he is paid for only one hour.
knowing that mike is paid 217 in 35 hours we divide
- 217 divided by 35 = 6.2
and that’s the answer to check if it’s right we multiple 6.2 by 35
- 6.2 times 35 = 217
wich shows it is correct.
and that is how I came to that solution.
The expression 3(-2m + 5) - 6(-4m - 2) can be written in the form am + b. What is the value of a + b?
Answers
Answer: 45
Step-by-step explanation:
3(-2m + 5) -6(-4m - 2) =
-6m + 15 + 24m + 12=

18= a 27= b 27 + 18= 45
The value of the expression a + b is 45.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
First, we can simplify the expression using the distributive property:
3(-2m + 5) - 6(-4m - 2) = -6m + 15 + 24m + 12
Combining like terms, we get:
18m + 27
So, a = 18 and b = 27, which means:
a + b = 18 + 27 = 45
Therefore,
The value of a + b is 45.
