1. 2(4x - 3) - 8 = 4 + 2x
Can sb help slove this using PEMDAS ?
Answer:
x=3
Step-by-step explanation:
1) get rid of the parenthesis by distributing the 2. You will get 8x-6-8=4+2x
2) Now combine like term on each side of the equal sign. You will get 8x-14=4+2x
3) Move the 14 to the right side of the equation making it +14 and move your 2x to the left side of the equation making it -2x. You will get 8x-2x=4=+14
4) calculate each side. You will get 6x=18
5) Divide both sides. You will get x=3
The sum of two odd numbers is even
Answer:
Yes.
Step-by-step explanation:
The sum of two odd numbers is always even. The product of two or more odd numbers is always odd. The sum of an even number of odd numbers is even, while the sum of an odd number of odd numbers is odd.
Each letter of the alphabet is printed on an index card. What is the theoretical probability of randomly choosing any letter except Z? Write your answer as a fraction or percent rounded to the nearest tenth.
Answer:
25/26 or 96.2%
Step-by-step explanation:
In the alphabets, we have 26 letters
If we remove Z, we have A -Y which is 25 alphabets
The question requires us to find the theoretical probability of choosing any other letter that is not Z
Probability= ratio of other alphabets that are not z to the number of letters in the alphabets.
Probability = 25/26 (as a fraction)
Probability = 0.9615 x 100 = 96.2% (as a percentage and to the nearest tenth)

Find the measure of the indicated angle
Answer:
[tex]m\angle A = 98[/tex]Step-by-step explanation:
Since it's a triangle all it's interior angles sum up to 180°
The triangle is isosceles which means two of it's angles are equal
From the question
[tex]m\angle B = m\angle C = 41 \degree[/tex]
So to find [tex]m \angle A[/tex] add up all the angles and equate it to 180° and solve for A
That's
[tex]m\angle A + m\angle B + m\angle \: C = 180 \\ m\angle A = 180 -m\angle B - m\angle \: C \\ m\angle A = 180 - 41 - 41 \\ = 180 - 82[/tex]
We have the final answer as
[tex]m\angle A = 98[/tex]

Q:Resolve this into partial fraction.
9/(X-1)(X+2)^2
Answer:
[tex]\frac{1}{x-1}[/tex] - [tex]\frac{1}{x+2}[/tex] - [tex]\frac{3}{(x+2)^2}[/tex]
Step-by-step explanation:
Expressing as a partial fraction
[tex]\frac{9}{(x-1)(x+2)^2}[/tex] = [tex]\frac{A}{(x-1)}[/tex] + [tex]\frac{B}{(x+2)}[/tex] + [tex]\frac{C}{(x+2)^2}[/tex] ( A, B, C are numerical values to be found )
Multiply both sides by (x - 1)(x + 2)²
9 = A(x + 2)² + B(x - 1)(x + 2) + C(x - 1)
Choose value for x that are zeros of the factors and substitute into right side
x = - 2 : 9 = - 3C ⇒ C = - 3
x = 1 : 9 = 9A ⇒ A = 1
x = 0 : 9 = 4A - 2B - C , that is
9 = 4 - 2B + 3 = - 2B + 7 ( subtract 7 from both sides )
2 = - 2B ⇒ B = - 1, then
A = 1, B = - 1, C = - 3
Thus
[tex]\frac{9}{(x-1)(x+2)^2}[/tex] = [tex]\frac{1}{x-1}[/tex] - [tex]\frac{1}{x+2}[/tex] - [tex]\frac{3}{(x+2)^2}[/tex]

if the sides of a triangle are produced in order prove that the sum ofexterior angles so formed is equal to four right angles
Step-by-step explanation:
Let a, b, c be the measures of the interior angles and x, y, z be the measures of the exterior angles of the triangle. Where x and adjacent to a, y is adjacent to b and z is adjacent to c.
By interior angle sum postulate of a triangle:
a + b + c = 180°... (1)
Therefore, by remote interior angle theorem:
x = b + c.... (2)
y = a + c..... (3)
z = a + b.... (4)
Adding equations (2), (3) & (4)
x + y + z = b + c + a + c + a + b
x + y + z = 2a + 2b + 2c
x + y + z = 2(a + b + c)... (5)
From equations (1) & (5)
[tex]x + y + z = 2 \times 180 \degree \\ x + y + z = 360 \degree \\ x + y + z = 4 \times 90\degree \\ x + y + z = 4 \: right \: angles[/tex]
Thus, the sum of exterior angles so formed is equal to four right angles.

Someone please help
i need help please please :((
Answer: 9^-16
Step-by-step explanation:
If an exponents have the same base and are being multiplied together, all you do is just add the exponents and make the base stay the same
9[tex]9^{-53} * 9^{37} = 9^{-16}[/tex]
Negative exponents can be rewritten as positive exponents if you put them in the denominator.
[tex]x^{-a}=\frac{1}{x^a}[/tex]
Using this rule, we can rewrite the equation.
[tex]9^{-53}*9^{37}=\frac{1}{9^{53}}*9^{37}[/tex]
[tex]\frac{9^{37}}{9^{53}}[/tex]
Then, we can use exponent division rules.
[tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]\frac{9^{37}}{9^{53}}=9^{37-53}[/tex]
[tex]9^{-16}[/tex] or [tex]\frac{1}{9^{16}}[/tex]
Hope this helps.

Bri wants to buy as many flip flops as she can at the store. Each flip flop costs $4 and she has $50 with her. Write an inequality to show the maximum number of flip flops Bri can buy.
Answer:
she can buy 12½flip flops
Step-by-step explanation:
it's actually easy : just do 50÷4 but then u will get something like 12.5 so if you are confused , you can divide by the closest number to 50 and the number which is a multiple of 4
so,
48÷4 = 12 and with the remaining 2 $ she can buy a half flip flop more if she wants because 4/2
Therefore , the total number of flip flops she can buy = 12½ flip flops
Solve the simultaneous equations 4x+y=10 X-5y=13
Answer: 4x + y = 10 is -y+10/4 X-5y=13 is x=5y+13
Step-by-step explanation:
The value of x and y in the equations given are -2 and 3 respectively.
What are equations?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given are two equations, 4x+y = 10 and x-5y = 13, we need to solve the equations,
4x+y = 10.......(i)
x-5y = 13
x = 13+5y......(ii)
Substituting eq(ii) in eq(i)
4(13+5y)+y = 10
52+20y+y = 10
21y = 10-52
21y = -42
y = -2
Put y = -2 in equation (ii),
x = 13+5(-2)
x = 13-10
x = 3
Hence, The value of x and y in the equations given are -2 and 3 respectively
