-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.

Pulling out like terms
3.1 Pull out like factors :
8x2 - 8 = 8 • (x2 - 1)
Trying to factor as a Difference of Squares:
3.2 Factoring: x2 - 1
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 1 is the square of 1
Check : x2 is the square of x1

Theory - Roots of a product
4.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Equations which are never true:
4.2 Solve : 8 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.3 Solve : x+1 = 0
Subtract 1 from both sides of the equation :
x = -1
Solving a Single Variable Equation:
4.4 Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1

Jesse buys a necklace that is on sale for 25% off the original price is 119.50 if tax is 7% what is the total price that Jesse will pay for the necklace
Answer:
$95.89875
Step-by-step explanation:
The original price of the necklace is 119.5. And we are subtracting 25% from this. 119.5 - 25% = 119.5 - 1/4 since 25% is 25/100 which is also 1/4.
So without tax, the price of the necklace is 119.5 - 29.875 which is 89.625.
The tax is 7%. So we should add 89.625 to 7%. This is complicated, but it should result in 95.89875.
If we round this to the nearest cent, it should be $95.9.

Solve for x.
-3x + 50 = 101
-3x + 50 = 101
-50 -50 subtract 50 from both sides, 50's cancel out from the left.
___________ solve for 101 - 50.
-3x = 51
___ ___ divide -3 on both sides, -3's cancel out on the left.
-3 -3 solve for 51 ÷ -3.
x = -17, is the answer.

if xr-st=r, which expression represents x
Answer:
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
Try this:
rx - st = r
remove st from the rx side
rx = r + st
now divide by r
x = (r + st)/r

Question 33
Suppose 96 % of students chose to study Spanish their junior year, and that meant that there were 696 such students. How many students chose
not to take Spanish their junior year?
Answer:
110
Step-by-step explanation:
If 12% studied Spanish, then 88% did not. The ratio of those who did not to those who did is ...
88 : 12 = 22 : 3
Then the number of students who did not study Spanish is ...
(22/3)×15 = 110 . . . . did not study Spanish
22:3 is a reduction of the ratio 88:12, by factoring 4 from each number. 15 is the number of students corresponding to 12% of the class. It is found in the problem statement. Essentially, we're saying that we want to know the number of students in the other 88% of the class, given that 15 students make up 12% of the class. There are many ways to write equations for this. I think this proportion is the easiest to think about.
If F is the size of the freshman class, and n is the number Not studying Spanish, you have 12%·F = 15, and 15 + N = F. You can solve the first equation for F, then the second equation for N, which is what you really want to know. F = 15/.12 = 125; N = F -15 = 125-15 = 110.
These two equations are reasonably straightforward, but to my lazy way of thinking, it is an extra equation and an extra calculation that are not needed to get to the answer.
You don't need to reduce the ratio from 88/12 to 22/3 to work the problem using ratios. The only reason for doing that is so there is a 3 in the denominator that cancels a factor of 3 in 15, so the only math you really need to do is 22·5 = 110. It helps immensely to know your multiplication tables, and to be able to recognize multiples of 2 and 4.
Step-by-step explanation:
percentage of students not to take spanish is 4%
answer is 696*4/100=27.84
so 28 students not to take spanish

Suppose a stock is selling on a stock exchange for 6 3/4 dollars per share. If the price increases 3/4 per share, what is the new price of the stock? Leave your answer as a proper fraction or mixed number.
Step-by-step explanation:
If the price increases 3/4 per share, the new price of the stock =
6¾ + ¾ =
27 /4 + ¾ =
30 /4 =
15/2 or 7½
The new price of the stock which increases 3/4 per share is $ 7 1/2.
Given data:
A stock is selling on a stock exchange for 6 3/4 dollars per share.
If the price of the stock increases by 3/4 dollars per share, you can add 3/4 to the current price of 6 3/4 dollars per share:
6 3/4 + 3/4
To add the whole numbers and fractions separately:
6 + 0 + 3/4 + 3/4
Adding the whole numbers and fractions:
6 + 1 1/2
A = 7 1/2
Hence, the price of the new stock is $ 7 1/2

Is the relation below a function? If it is a function, state its domain.
{(0,2),(2,4),(1,7),(2,5)}
A. The relation is not a function.
B. The relation is a function. The domain is {0,1,2}
C. The relation is a function. The domain is {2,4,5,7}
D. The relation is a function. The domain is {0,1,2,4,5,7}
Answer:
A
Step-by-step explanation:
The relation is not a function. All you need to solve this problem is the following: Relations are NOT functions when the domain values repeat!
Note: The domain is the set of input values. The domain is x, the first number in the pair. For example, in the pair (0, 2), the domain is 0.
In the relation {(0,2),(2,4),(1,7),(2,5)}, 2 is repeated two times, which, by definition, means that the relation is not a function.

A right triangle has a leg that is 2.70 m long and a hypotenuse that is 7.76 m long. What is the length of the other leg of the triangle in meters using the rules for significant digits?
Applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.
Recall:
Pythagorean Theorem is given as: [tex]a^2 + b^2 = c^2[/tex]a and b are the two other legs of a right-angled triangle, while c is the hypotenuse.Using the Pythagorean Theorem, we are going to find the length of the other leg of the triangle that has:
a = 2.70 m (a leg)c = 7.76 m (hypotenuse)Substitute and find the value of b (the other leg).[tex]2.27^2 + b^2 = 7.76^2\\\\b = \sqrt{7.76^2 - 2.27^2} \\\\b = 2.607[/tex]
Therefore, applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.
