Answer:
-20 = - 20
Step-by-step explanation:
Suppose the number is x
three less than a number means x - 3 which is equal to 14 more than twice a number means 2x +14.
So we can write
x - 3 = 2x +14 - - - - - A
subtract x from both sides
x - x - 3 = 2x - x +14
-3 = x +14
Subtract 14 from both sides
-3 - 14 = x +14 - 14
-17 = x
Or x = - 17
Now can verify our answer by putting the value of x in Eq A
-17 - 3 = 2 x (-17) +14
-20 = - 34 +14
-20 = - 20

Jamie's company prepares a gift bag for each seat at an awards ceremony. The theater has 30 sections, each with 70 seats. Gift bags for 5 sections will have concert tickets. The rest of the gift bags will have coupons. How many gift bags will have coupons?
Answer:
Step-by-step explanation:
30(total num of sections)-5(amount of sections with concert ticket)=25
25x70(seats per section)=1750
1750 will get coupons
(you dont need the bits in brackets tehy are there to just explain so you know whay and why im doind a calculation)
Hence, the bags will get coupons are [tex]1750[/tex].
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Answer:
y = 10
x = 17
Step-by-step explanation:
4y - 3 = 37
4y = 37 + 3
4y = 40
y = 40 / 4
y = 10
3x - 9 = 42
3x = 42 + 9
3x = 51
x = 51 / 3
x = 17
Hope that helps!
Answer:
x = 17
y = 10
Step-by-step explanation:
Parallel sides are equal in length, so set them equal to each other.
3x - 9 = 42 --> Add 9 to both sides.
3x = 51 --> Divide both sides by 3.
x = 17
4y - 3 = 37 --> Add 3 to both sides.
4y = 40 --> Divide both sides by 4.
y = 10
Use your knowledge of special cases to solve the problem.

b)9a^2 - 4b^2
c)9a^2 - 12ab + 4b^2
Answer:
C
Step-by-step explanation:
We want to simplify:
[tex](3a-2b)^2[/tex]
Recall the perfect square trinomial pattern:
[tex](a+b)^2=a^2+2ab+b^2[/tex]
Let a = 3a and b = -2b. Thus:

Simplify:

describe what congruent figures and similar figures have in common
Answer:
Congruent figures have the same measurements in angles (degrees) and sides (units).
Similar figures are figures that have the same general shape and don't necessarily have to have the same size or measurements.
Something they have in common are corresponding angles and corresponding sides.
Solve for the nearest whole number
Solve for the missing angle
Answer:
33°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{6}{11}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{6}{11}[/tex] ) = 33° ( to the nearest whole number )

There is a bag filled with 2 blue, 4 red and 5 green marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting 2 different colours?
Answer:
Question:
A bag with 2 blue (B), 4 red (R) and 5 green (G) marbles (total 11 marbles).
Two are drawn at random without replacement.
Find probability of getting two marbles of same colour.
Solution:
We can get either 2B, 2R or 2G as successful outcomes.
To get two blue marbles (2B),
probability of the first one being blue = P(B)=2/11
probability of the second blue marble = P(-B)=1/10 (one left out of 10 left)
Probability that both are blue (use multiplication rule)
P(2B)=(2/11)(1/10)=2/110
Similarly, for two red marbles
P(2R)=(4/11)(3/10)=12/110
and for two green marbles
P(2G)=(5/11)(4/10)=20/110
Since all three events 2B, 2R and 2G are mutually exclusive, the probability
that any one can happen is the sum of the individual probabilities, thus
probability of getting two marbles of the same colour (without replacement)
=P(2B)+P(2R)+P(2G)
=2/110 + 12/110 + 20/110
=34/110

Find the interest
earned:
$4,000 for 4 years at
5% annual simple
interest
Answer:
Step-by-step explanation:
Answer:
I = $ 800.00
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 4000 × 0.05 × 4 = 800
I = $ 800.00
The simple interest accumulated
on a principal of $ 4,000.00
at a rate of 5% per year
for 4 years is $ 800.00.

The area of a rectangle can be represented by the expression
x^2+2x-3
If the dimensions of the rectangle are known to be the factors of the expression, write each dimension of this rectangle as a binomial. (Write the two binomial factors that you are mulitplying together to get the area).
Answer:
I believethe answers are (x-1)(x+3)
Step-by-step explanation:
x^2 + 2x - 3 can be simplified to
(x+3)(x-1)
The factors of this expression are therefore (x+3) and (x-1)
The binomial of each dimension is:
x+3
x-1
