Write a system of equations that represents the given equation then find the two numbers
The sum or two numbers is 68. The difference is 12
Answer:
40 and 28
Step-by-step explanation:
We have two unknown numbers, so let's call them x and y for now.
We know the sum of the two numbers is 68, and the difference is 12, so let's substitute those two numbers for x and y:
x+y=68
and
x-y=12
Because both of these systems are true, we can take both these equations and combine them, by adding each side of one equation with the corresponding side of the other.
So we have:
(x+y)+(x-y)=(68)+(12)
2x=80
x=40
Now we know one of the numbers, x, is equal to 40, so now we can plug that number back into one of the two original equations, x+y=68 or x-y=12. I'll choose x-y=12.
After plugging in x, we get:
40-y=12
-y=-28
y=28
So now we have figured out x and y, which are 40 and 28.

Someone please help me asap. I’m confused and need help. Complete the table using the function n = 9b + 19
answer: you would just substitute all of the values you see for b into the equation where there's a b
Answer:
55; 64; 73
Step-by-step explanation:
In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19
if b = 4:
n = 9(4) + 19
n = 36 + 19
n = 55
if b = 5:
n = 9(5) + 19
n = 45 + 19
n = 64
if b = 6:
n = 9(6) + 19
n = 54 + 19
n = 73
Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it
if b = 7:
n = 9(7) + 19
n = 63 + 19
n = 82
Work is correct
Try not to overthink it ^-^

At noon the temperature was -10° F. Over the next 4 hours the temperature went up 12°. Then every hour until 10 pm the temperature dropped 2°. What was the temperature at 10 pm?
Answer:
-10 degrees
Step-by-step explanation:
at noon the temp was -10. -10 + 12 = 2 and that is at 4 o'clock 2- 6 hours ( time until 10 pm) x 2. 2 - 12 = -10.
Answer: 0º F.
Step-by-step explanation:
Noon = 12 pm
At Noon it was -10º F, over the next 4 hours it went up to 12º F.
Noon + 4 hours = 4 pm
The temperature dropped 2º F every hour until 10 pm which means for 6 hours the temperature dropped.
6x2º F = 12º F which means the temperature dropped by 12º F.
12º F - 12º F = 0º F

[tex]5x - 15 = 3x + 7[/tex]
Subtract the sides of the equation plus 15
[tex]5x = 3x + 7 + 15[/tex]
[tex]5x = 3x + 22[/tex]
Subtract the sides of the equation minus 3x
[tex]5x - 3x = 22[/tex]
[tex]2x = 22[/tex]
Divided the sides of the equation by 2
[tex]x = \frac{22}{2} \\ [/tex]
[tex]x = 11[/tex]

Alvin incorrectly simplified 4 x 42 and got an answer of 166.
What did Alvin do wrong? Explain and then solve the
problem correctly.
the answer is 168
Step-by-step explanation:
you times 4 by 2 you get 8.
now you got to times 4 by 40 and you get 160

29.8 is 10 times as much as what
Answer:
298
Step-by-step explanation:
29.8 is 10 times as much as 298
The required proportion value is 2.98 which is equal to one-tenth of 29.8.
Given that,
To determine 29.8 is 10 times as much as a number.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number be x,
According to the question.
29.8 = x10
x = 29.8 / 10x
x = 2.98
Thus, the required proportion value is 2.98 which is equal to one-tenth of 29.8.

All solutions to the equation are x = 2, -1 + i√3, and -1 - i√3 two roots are complex and one root is real.
What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have:
x³ - 8 = 0
Using identity:
a³ - b³ = (a - b)(a² + ab + b²)
(x - 2)(x² + 2x + 4) = 0
x = 2
x² + 2x + 4 = 0
Using quadratic formula:
[tex]\rm x = \dfrac{-2 \pm\sqrt{2^2-4(1)(4)}}{2(1)}[/tex]
x = -1 ± i√3
Thus, all solutions to the equation are x = 2, -1 + i√3, and -1 - i√3 two roots are complex and one root is real.

Show that 3 · 4n + 51 is divisible by 3 and 9 for all positive integers n.
Answer:
4^1 + 17 = 21 , which is divisible by 3. 4^k + 17 and 3 * 4^k are both divisible by 3, so 4^k + 17 + 3 * 4^k is divisible by 3 as well. 3 * (4^n + 17) would be divisible by 9

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
A. -4
B. -2
C. -1
D. 1
Answer:
The answer would be A. -4
Step-by-step explanation:
If you right it out like x-6=5(x+2), then you distribute the 5, you get: x-6=5x+10. Then subtract x from both sides, you get: -6=4x+10. Subtract 10 from both sides, you get: -16=4x. The all you have to do is divide both sides by 4, and you get: -4=x
