Answer:
The expressions are as follows:
$5+$3=$84+2=68+6=14Remember whenever it's written total it means you have to do addition. Hope it helps you.
Olivia ordered 24 cupcakes and a layer cake. The layer cake cost $16 and the total cost of the order was $57. What was the price of each cupcake?
Let's use an equation to solve this problem.
[tex]y=24x+16[/tex]
Where x is the price of each cupcake, y is the total cost, 16 is the price of the layer cake, and 24 is the number of cupcakes.
[tex]57=24x+16[/tex]
[tex]41=24x[/tex]
[tex]x=\frac{41}{24}[/tex]
Which simplifies around to $1.71 dollars.
Hope this helps.

Step-by-step explanation:
If f(x) = 3x + 2 and g(x) = x2 + 1, which expression is equivalent to (fog)(x)?
Answer:
(fog)(x) = f(g(x)) = 3(x^2 + 1 ) + 2
Step-by-step explanation:
For this problem, you simply need to understand the notation (fog)(x) is equivalent to f ( g ( x ) ). This means you simply plug the function g(x) into each x within the function of f(x). Let's do this:
f(x) = 3x + 2
g(x) = x^2 + 1
f(g(x)) = 3(x^2 + 1 ) + 2
(fog)(x) = f(g(x))

(3x-4) - (4x-1)
Answer:
-x - 3
Step-by-step explanation:
(3x - 4) - (4x - 1) =
The first set of parentheses is unnecessary, so you can just remove it.
= 3x - 4 - (4x - 1)
To remove the second set of parentheses, you must distribute the negative sign to its left by the terms inside the parentheses. To do this, change every sign inside the parentheses.
= 3x - 4 - 4x + 1
Now combine like terms. Terms with x are like terms and are combined together. Therms without x are like terms and are combined together.
= 3x - 4x - 4 + 1
= -x - 3
equation of a line, use the slope intercept formula for points (3,-6) and (5,8) including a check.
please help me learn instead of telling me the answer :)
i’ll show u what i have so far
Answer:
y=7x-27
Step-by-step explanation:
The equation of a line is given by y=mx+C where m is the gradient of the line or slope and c is the intercept on your axis. according to your question, you are given two point on (3,-6) and (5,8). so we can get the gradient m= Y2-Y1/X2-X1= gradient. so Y1= -6, Y2=8 , X1=3, X2=5
slope= 8-(-6)/5-3=14/2=7. so m=7....so the equation of line can be written in form y=7x+C. but we need to find C. C can be gotten from where the line passes through (3,-6) that is when x=3, y=-6. so we can find C from that point. -6=7(3)+C..so we have -6=21+C. C=-6-21=-27
so the equation of the line is y=7x-27

Please simplify! x+9=21+3x-4+10
Answer:
-9
Step-by-step explanation:
Step 1 : Put like terms together
x + 9 = 21 + 3x - 4 + 10
Subtract 3x on both sides
-2x + 9 = 21 - 4 + 10
Subtract 9 on both sides
-2x = 21 - 4 + 10 - 9
Simplify
-2x = 18
Step 2 : Divide
[tex]\frac{-2x}{-2}[/tex] = [tex]\frac{18}{-2}[/tex]
x = -9
Answer:
x= -9
Step-by-step explanation:
- Put all the same signs together
x-3x = 21-4+10-9
*Quick tip:
-when you cross a sign with a number or without a number over the equal
sign you have to change the sign (positive to negative and negative to
positive.
-x and 1x is the same thing
- Calculate small sections by small sections
-2x = 17 + 1
-2x= 18
-2/-2x = 18/-2
x= -9

1 If one leg of a right triangle is 3 meters, and the hypotenuse is 5 meters, what is the length of the
missing leg?
i'm gonna assume that "leg" refers to length of the triangle, so comment if you think it is wrong.
Now when it comes to a right-angled triangle, the pythagoras theorem formula can be used.
Using algebra,
let the missing length be X.
By pythagoras theorem,
5² = 3² + X²
5² - 3² = X²
X² = 5² - 3²
X = sq root ( 5² - 3² )
= 4 m
Therefore, the length of the missing leg is 4m .
Write an integer expression using absolute value symbols to represent the verbal expression.
-the absolute value of negative eight-
Enter the correct answer in the box.
Answer:
[tex]Absolute\ Value = 8[/tex]
Step-by-step explanation:
Given
Digit = -8
Required
Determine the absolute value
The absolute value is calculated as follows;
[tex]Absolute\ Value = |Digit|[/tex]
Substitute -8 for Digit
[tex]Absolute\ Value = |-8|[/tex]
And it returns the positive of its input;
So
[tex]Absolute\ Value = 8[/tex]
What is 18.84 rounded to the nearest 10th
18.84 rounded to the nearest tenth is 18.8.
Rounding to place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
We can see that round a number to the nearest tenth, we need to look at the digit in the hundredth place. In this case, the number is 18.84.
Therefore, digit in the hundredth place is 4.
If the digit in the hundredth place is less than 5, we round down to the previous tenth. If it is 5 or greater, we round up to the next tenth.
Since 4 is less than 5, we round down. Therefore, 18.84 rounded to the nearest tenth is 18.8.

note: remember to take the comma out or ignore it. I put it in there to help make the number more readable
===========================================
Explanation:
Let x be the value of the sale in dollars.
x-1900 represents the leftover amount that is over 1900
eg: if x = 2200, then x-1900 = 2200-1900 = 300 is the the leftover amount
taking 9% of (x-1900) leads to the expression 0.09(x-1900) and this expression must be 1000 since this is the extra amount of money the salesman needs (he already has $1000 in base pay)
-------------
Solve for x
0.09(x-1900) = 1000
x-1900 = 1000/0.09
x-1900 = 11,111.11111 approximately
x = 11,111.11111 + 1900
x = 13011.1111
x = 13,011.11 rounding to the nearest cent

Find the value of a and b when a+b = -5, ab = -24
Step-by-step explanation:
a= - 5 - b
Subs. the above into...
ab = - 24
(-5-b)b = - 24
Therefore b=-24 or b=19
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
a + b = - 5 → (1)
ab = - 24 → (2)
Rearranging (1) expressing a in terms of b, that is
a = - 5 - b → (3)
Substitute a = - 5 - b into (2)
b(- 5 - b) = - 24 ← distribute left side
- 5b - b² = - 24 ( subtract - 5b - b² from both sides )
0 = b² + 5b - 24 ← in standard form
0 = (b + 8)(b - 3) ← in factored form
Equate each factor to zero and solve for b
b + 8 = 0 ⇒ b = - 8
b - 3 = 0 ⇒ b = 3
Substitute these values into (3) for corresponding values of a
b = - 8 : a = - 5 - (- 8) = - 5 + 8 = 3
b = 3 : a = - 5 - 3 = - 8
Thus
a = 3, b= - 8 or a = - 8, b = 3

What set(s) of numbers does 5 belong to?
Step-by-step explanation: For example, 5 can be written as 5/1. The natural numbers, whole numbers, and integers are all subsets of rational numbers.
Which equation represents this sentence? One-half the sum of a number and four is three less than the quotient of five and the number. 12n+4=5n−3 12(n+4)=5n−3 12n+4=3−5n 12(n+4)=3−5n
Answer:
Step-by-step explanation:
"one half the sum of a number and 4" is (1/2)(n + 4)
"three less than the quotient of 5 and the number" is 5/n - 3
putting this all together, we get
(1/2)(n + 4) = (5/n) - 3
