-7 times one is equal to minus seven.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find what times what is -7.
Whenever we see a times in an expression its nothing but multiplication.
Multiplication is a method of finding the product of two or more numbers
We need to find the two numbers whose product will be equal to minus seven.
We know that there is only one possibility.
-7×1=-7
and 1×-7=-7
Hence ,-7 times one is equal to minus seven.

Fractions are part of a whole. For example, if an object is divided into two equal parts, the value of each part is half or one-half of the total number of objects. Fractions can be expressed in the form: a/b
a is the numeratorb is the denominatorDISCUSSION
Fractions also have fractions in different forms but have the same value which are called equivalent fractions. Fractions can also be simplified. To find a fraction equal to a fraction, we can multiply (×) or divide (÷) the numerator and denominator of the fraction by the same number. And to simplify fractions, we can divide (÷) the numerator and denominator of the fraction with the same number.
**
There are various forms of fractions, including:
Common Fractions are fractions that consist of a numerator and denominator. Mixed fractions are fractions that consist of whole numbers and fractions. If the numerator of a fraction is greater than the denominator, the fraction can be converted into a mixed number. To get the mixed number form of a common fraction, divide the numerator of the fraction by the denominator. A decimal fraction is a fraction of tenths, hundredths, thousandths, and so on written using a comma (,).Percents are another form of fraction with a denominator of one hundred. Percent is written with the symbol %.**
Now from the discussion above, it turns out that ordinary fractions still have two more types, namely =
Pure Fraction➳ A pure fraction is a fraction whose numerator is smaller than the denominator.
Impure fractions➳ An impure fraction is a fraction whose numerator is greater than its denominator.

7. A caterer knows there is one broken egg in every 3 cartons. A carton contains 12 eggs.
A caterer plans to serve 1200 eggs. What is the best estimate the number of cartons the caterer should buy?
9514 1404 393
Answer:
103
Step-by-step explanation:
For 1200 eggs, the caterer needs ...
(1200 eggs)/(12 eggs/carton) = 100 cartons
of unbroken eggs.
The rate of broken eggs is 1 in 3×12 = 1 in 36, so the caterer must buy 36 eggs for each 35 unbroken eggs delivered.
Then the number of cartons that must be purchased is ...
(100 cartons)(36/35) = 102 6/7 cartons
The caterer should buy 103 cartons of eggs.
10(2x - 5) = -60

A square piece of cheese covers 10 square inches of a plate. What is the approximate length of one side of the piece of cheese? (Approximate to the nearest hundredth inch.)
3.14 inches
3.15 inches
3.16 inches
3.17 inches
Answer:
3.16 is the answer
Hope it helps!
Step-by-step explanation:
The approximate length of one side of the piece of cheese is 3.16 inches so option (C) will be correct.
What is a square?A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4× side
Length of diagonal of square = √(2) × side
Let's say the length of the side of the piece is x
Then,
Area = x²
Since it covers 10 inches² so it means it has an area of 10 inches²
So,
x² = 10 ⇒ x = 3.16 inches.
Hence "The approximate length of one side of the piece of cheese is 3.16 inches".

Write the equation of the line that passes through the points (3,-2) and (-2,8).
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
Let's find the slope (m) of line passing through points (3 , -2) and (-2 , 8) :

on Tuesday. Josiah 5/12 ate of his package on Monday and 1/2 of the package on
Tuesday. Who ate more? How much more?
9514 1404 393
Answer:
Josiah ate 1/12 package more
Step-by-step explanation:
Each of them ate 1/2 package on one of the days. On the other day, Rodney ate 1/3 = 4/12 of the package, and Josiah ate 5/12 of the package.
Josiah ate 5/12 -4/12 = 1/12 more of the package of cookies.

A line segment of length k is divided into 3 equal parts what is the distance between midpoints of the first and third segments
Line segment of length k is divided into 3 equal parts.
so first segment is 0-k/3 and third segment is 2/3k-k
so mid-pt of 1st = k/6 and 3rd = 5/6k
so the distance in between = 5/6k-k/6 = 4/6k = 2/3k

Answer:
x=9
Therefore angles 7x-4 = 6x-4 = 59 degree
Step-by-step explanation:
7x-4 = 6x-4 Findings; alternate angles
Although any coefficient angles can be set = to each other.
7x-6x-4 = +5 Subtract 6x from both sides
x -4 = 5
x = 5+4 Add 4 to each side
x = 9
Find the angle degree
6(x) + 5 = 7(x) - 4 Plug 9 in to x
6(9) + 5 = 7 (9) - 4
54 + 5 = 63-4
59 = 59
x = 59 degree.

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once.
Write about what additional information you would need to create a two-variable equation for the scenario. What kind of problem could you solve with your equation?
Answer:
To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.
