Answer:
14
Step-by-step explanation:
It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5'.
So we'd put 15 in y's place. It'll look like this (15 - 9).
Then we'd put 5 in x's place. It'll look like this (3 + 5).
You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!

What is the product of (-3x2/3) and (4x3/4)?
Answer: - 1/x or [tex]-\frac{1}{x}[/tex]
Step-by-step explanation:
(-3x^2 /3 ) * (4x^3 / 4)
=> - (3x^3 / 4) * (4x^3 / 3)
=> - (x^2 * 4) / 4x^3
=> - (x^2 / x^3)
=> - 1/x or [tex]-\frac{1}{x}[/tex]
The product of the two numbers will be -6.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two numbers are (-3x2/3) and (4x3/4).
To find the product of (-3 * 2/3) and (4 * 3/4), we first need to simplify each expression:
(-3 x 2/3) = -2
(4 x 3/4) = 3
Next, we multiply the two simplified expressions:
-2 x 3 = -6
So, the product of (-3 * 2/3) and (4 * 3/4) is -6.

tomas works for a cellphone company. he has a base salary of $350 each month and earns an additional $40 for each cellphone he sells. write a function (linear equation) in slope-intercept form (y = mx + b) that represents tomas' total earnings (y) for one month for selling (x) number of cellphones.
Use the linear equation from question 1 to determine Tomas' earnings for a month where he sold 30 cellphones. *
Answer:
The function is [tex]y = 40x + 350[/tex]
When he sold 30 cellphones, he earned $1550.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1), and b is the y-intercept, that is, the value of w when x = 0.
Base salary of $350 each month and earns an additional $40 for each cellphone he sells.
If he sells 0 cellphones, he earns $350, so [tex]b = 350[/tex].
For each cellphone he sells, he earns $40, so [tex]m = 40[/tex]
The function is:
[tex]y = mx + b = 40x + 350[/tex]
Tomas' earnings for a month where he sold 30 cellphones.
This is y when [tex]x = 30[/tex]. So
[tex]y = 40*30 + 350 = 1550[/tex]
When he sold 30 cellphones, he earned $1550.

solve this system using elimination. 3x - 4y = -5, -10x + 4 = 12
Answer:
x = -4/5, y = 13/20
Step-by-step explanation:
-10x + 4 = 12
-10x = 8
x = -4/5
3x - 4y = -5
3(-4/5) - 4y = -5
-12/5 - 4y = -5
-4y = -13/5
y = 13/20
Double check:
3x - 4y = -5
3(-4/5) - 4(13/20) = -5
-12/5 - 13 = -5 (true)

honestly in my opinion thats my answer but it might be wrong. you could add or multiply it, I added the ingredients 3 times but it’s more simple to multiply each by 3.
3 times 3 = 9
4 times 3 = 12
5 times 3 = 15
2 times 3 = 6
1 times 3 = 3

Sophia uses 3 3/4 cups of flour for each cake she makes. She has a 10-pound bag of flour that costs $8.79 and contains 152 quarter-cup servings.
Question 1
Part A
How many cakes can Sophia make with this flour?
The number of cakes Sophia can make is 10.
The bag of flour contains 152 quarter-cup servings. So, the quantity in t he bag has to be divided by four.
Number of cups = 152 / 4 = 38 cups
In order to determine the number of cakes she can make, divide the number of cups in the bag by the cups needed to make one cake.
38 ÷ 3 3/4
38 ÷ 15/4
38 × 4/15 = 10.1 cakes

Sophia will be able to make 10 cakes with this amount of flour.
Since Sophia uses 3 3/4 cups of flour for each cake she makes, and she has a 10-pound bag of flour that costs $ 8.79 and contains 152 quarter-cup servings, to determine how many cakes can Sophia make with this flour you must perform the following calculation:
3/4 = 0.75 (152/4) / 3.75 = X 38 / 3.75 = X 10.13 = X
Therefore, Sophia will be able to make 10 cakes with this amount of flour.

32 = 4(n – 5) and -s + 11 = 17 please solved Both of the following
Answer:
n=13 s=-6
Step-by-step explanation:
Hope this helps :)
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
32=4(n−5);−s+11=17
Rewrite equations:
32=4n−20;−s+11=17
Step: Solve 32=4n−20 for n:
32=4n−20
32+−4n=4n−20+−4n(Add -4n to both sides)
−4n+32=−20
−4n+32+−32=−20+−32(Add -32 to both sides)
−4n=−52
−4n/ −4 =/ −52/ −4
(Divide both sides by -4)
n=13
Step: Substitute 13 for n in −s+11=17:
−s+11=17
−s+11=17
−s+11+−11=17+−11(Add -11 to both sides)
−s=6
−s/ −1 = 6/ −1
(Divide both sides by -1)
s=−6
Answer:
n=13 and s=−6

Answer:
[tex]7[/tex]
Step-by-step explanation:
This means that there are 20 terms in between 11 and 31
[tex]31-11=20[/tex]
Since we know that the [tex]11th[/tex] term is [tex]29[/tex] and the [tex]31st[/tex] term is [tex]169[/tex], you can subtract the two to find out the values in between
[tex]169-29=140[/tex]
Now all we have to do is divide the values in between by the number of terms to find the common difference.
[tex]\frac{140}{20} =7[/tex]
Therefore the common difference is [tex]7[/tex]
