The following statements are true about the coins Calvin and Sasha have collected.
Calvin and Sasha have the same amount of money.
Calvin has only quarters.
• Sasha has dimes, nickels, and pennies.
Calvin has the same number of quarters as Sasha has dimes.
Sasha has $1.95 in coins that are not dimes.
Exactly how many quarters does Calvin have?
Answer:
bhai sorry bhai Ham Hindi Wale Hain English Nahin samajhte to please Ham bhi a question mat dena Humko is question ka answer Nahin patahai
The amount of money Calvin and Sasha have, is an illustration of equivalent expressions.
Calvin has exactly 13 quarters
From the question, we have:
[tex]\mathbf{Calvin = 0.25Q}[/tex]
[tex]\mathbf{Sasha = 0.05N + 0.01P + 0.10D}[/tex]
Calvin has the same number of quarters as Sasha has dimes.
So, we have:
[tex]\mathbf{Q = D}[/tex]
Sasha has $1.95 in coins that are not dimes.
So, we have
[tex]\mathbf{0.05N +0.01P = 1.95}[/tex]
They have the same amount of money i.e.
[tex]\mathbf{Calvin = Sasha}[/tex]
This gives
[tex]\mathbf{0.25Q = 0.05N + 0.01P + 0.10D }[/tex]
Substitute [tex]\mathbf{0.05N +0.01P = 1.95}[/tex]
[tex]\mathbf{0.25Q = 1.95 + 0.10D }[/tex]
Substitute [tex]\mathbf{Q = D}[/tex]
[tex]\mathbf{0.25Q = 1.95 + 0.10Q }[/tex]
Collect like terms
[tex]\mathbf{0.25Q -0.10Q= 1.95 }\\[/tex]
[tex]\mathbf{0.15Q= 1.95 }[/tex]
Divide both sides by 0.15
[tex]\mathbf{Q= 13 }[/tex]
Hence, Calvin has exactly 13 quarters

Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel,
perpendicular, or neither.
7y = 3x + 1; 14x + y = 12
x - 2y = 10; y = x + 1
3x - 2y = -3; 3y = -2x + 3
1/8x + y = 5; y = -8%
y = 3x - 1; 12x - 4y = 12
Parallel
Perpendicular
Neither
Answer:neither, neither, perpendicular , neither
parallel
Step-by-step explanation:put each line in the form y=mx+b
if m=m they are parallel
if m times m = -1 they are perpendicular

1/2-1/4x ≥ -1/4
Answer:
x [tex]\leq[/tex] 3
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex]x [tex]\geq[/tex] - [tex]\frac{1}{4}[/tex]
the first step is to subtract [tex]\frac{1}{2}[/tex] from both sides of the equation.
[tex]\frac{1}{2}[/tex] - [tex]\frac{1}{4}[/tex]x [tex]\geq[/tex] - [tex]\frac{1}{4}[/tex]
-[tex]\frac{1}{2}[/tex] - [tex]\frac{1}{2}[/tex]
----------------
-[tex]\frac{1}{4}[/tex]x [tex]\geq[/tex] - [tex]\frac{3}{4}[/tex]
then, divide both sides of the equation by - [tex]\frac{1}{4}[/tex].
x [tex]\leq[/tex] 3
(since we divided both sides by a negative number, to isolate x, the [tex]\geq[/tex] changed to [tex]\leq[/tex].)
Answer:
1/2 - 1/4x ≥ -1/4
multiply both sides by the l.c.m of the both sides(4)
4(1/2 - 1/4x )≥ -1/4 ×4
2 - x ≥ -1
Collect the like terms
-x ≥ -3
Divide both sides by -1
x ≤ 3(when you divide by a negative number the equality changes)

is the least number to be added to 5607 to get a perfect square.
pls add the steps.
Answer:
18
Step-by-step explanation:
70^2 = 4900 < 5607 < 6400 = 80^2
so sqrt(5607) is a two-digit number with tenth-digit 7
71^2 = 5041, 72^2 = 5184, 73^2 = 5329, 74^2 = 5476, 75^2 = 5625
so the smallest square bigger than 5607 is 75^2, which is 5625
so the number should ne 5625 - 5607 = 18

Answer:
see explanation
Step-by-step explanation:
let the two consecutive odd numbers be n and n + 2 , then
n + n + 2 = 148 , collect like terms
2n + 2 = 148 ( subtract 2 from both sides )
2n = 146 ( divide both sides by 2 )
n = 73
n + 2 = 73 + 2 = 75
The 2 numbers are 73 and 75
----------------------------------------------------------------
let width be w then length = 2w - 6
The perimeter (P) is calculated as
P = 2(width + length) , then
2(w + 2w - 6) = 54 ( divide both sides by 2 )
w + 2w - 6 = 27 , collect like terms
3w - 6 = 27 ( add 6 to both sides )
3w = 33 ( divide both sides by 3 )
w = 11
2w - 6 = 2(11) - 6 = 22 - 6 = 16
length = 16 in and width = 11 in
Hello,
Answer: 73,75
Step-by-step explanation:
1st Question Answer
x -> 1st
x+2 -> 2nd
So... Since it is equal to 148 then we write...
x+x+2=148
Combine Like Terms
2x+2=148
Subtract 2 from both sides
2x=146
Divide 2 to both sides
x=73 and +2 = 75
In Final: The two consecutive odd integers are 73 and 75
2nd question)
Width of rectangle is x inches
2x-6
Since perimeter = 2(length+witdth)
54 = 2(2W - 6) + 2W, (substitute P = 54 and L = 2W - 6)
66=6w
w=11
To find the length: Substitute
54=2l+2(11)
32=2L
L=16

the product of eight and a number squared decreased by 5
The expression that can be formed by the given sentence is 8x² - 5.
What are expressions?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)So, for the expression as follows:
Eight and a number squared decreased by 5 can be:
Now, let the number be 'x'.
So, product of 8 and number squared: (8x²)Decreased by 5: (-5)Hence, the expression we obtain is:
8x² - 5
Therefore, the expression that can be formed by the given sentence is 8x² - 5.

10³ multiply 22 by to get an answer of 22,000.
The correct option is (D)
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
We have to multiply 22 such that it gives 22, 000.
let the number that being multiplied be x.
So, 22x = 22000
x= 22000/22
x= 1000
x= 10³
Hence, 10³ multiply 22 by to get an answer of 22,000.
