The subtraction problem 11.5−7.2 can be rewritten as the addition problem _[blank]_.
The subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression of subtraction is,
E = 11.5−7.2
The expression in the form of addition will be converted by changing the sign of 7.2.
E= 11.5 - (-7.2)
E = 11.5 + 7.2
Therefore, the subtraction expression 11.5−7.2 in the form of addition will be 11.5 + 7.2.

The cost at a store for a package of pens is $3 and for a three-ring binder
is $4. Write a variable expression for the cost of buying p packages of
pens and b binders. How much would 3 packages of pens and 8 binders
cost?
Hey there! I'm happy to help!
Our question tells us that the number of packages is p and that the number of binders is b.
Each package is $3, so for every p we have, we will have 3 more dollars. So we have 3×p, which is written as 3p.
The same goes for binders. For every binder, we have 4 more dollars, so we have 4×b which is just written as 4b.
An expression is just a number sentence without an equal sign, so something like 1+1 or 7x². The variables are just the letters or symbols that represent an unknown quantity (so 7x² is a variable expression).
Our total cost is going to be the cost of our packages and our binders, so we combine the 3p and 4b we previously came up with, so our expression is 3p+4b.
Now, we can plug in our amounts of each thing into the equation. We will insert our 3 packages in plae of the p and our 8 binders in place of the b to find our cost.
In algebra, you can also write multiplication as a number outside of a number in parentheses so 4(2)=8 for example.
3(3)+4(8)
9+32
41
So, the total cost is $41.

solve for d
Answer:
D = 2/5 or 0.4
Step-by-step explanation:
3/2 = 5d - 1/2
move the terms
3/2 - 5d = -1/2
calculate the difference
-5d = -2
divide both sides by -5
2 = 2/5

Answer:
x=8
Step-by-step explanation:
3(x-5)+1=2+x
Subtract 1 from both sides.
3(x-5)=1+x
Distribute the 3
3x-15=1+x
Add 15 to both sides.
3x=16+x
Subtract x from both sides.
2x=16
Divide both sides by 2.
x=8

Answer:
74
Step-by-step explanation:
3 3/7 , 4 2/7, 5 1/7, .... 66
=> could be changed into :
24/7, 30/7, 36/7, ...... 462/7
let the numbers = n
462 = 24 + (n-1)(6)
462 = 24 + 6n -6
462 = 6n +18
6n=462-18
6n = 444
n = 444/6 = 74

Rafael wants to wallpaper the back wall of his bedroom. The wall is in the shape of a rectangle. Its length is 13 feet and its width is 9 feet. Suppose wallpaper costs $7 for each square foot. How much will wallpaper cost for the wall?
Answer:
$819
Step-by-step explanation:
First we find the area of the wall so we multiply 13ft x 9ft.
13ft x 9ft = 117ft
We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.
117 x 7 = $819

f(x)=2(x)^2-2, Find f(2-a)
f(2-a)=2(2-a)^2-2
Answer:
2a² - 8a + 6Step-by-step explanation:
Given function:
f(x) = 2x² - 2To find f(2 - a) substitute x with 2 - a:
f(2 - a) = 2(2 - a)² - 2 = 2(4 - 4a + a²) - 2 =2a² - 8a + 8 - 2 =2a² - 8a + 6f(x)=2(x)^2-2
[tex]\\ \rm\hookrightarrow f(2-a)[/tex]
[tex]\\ \rm\hookrightarrow 2(2-a)^2-2[/tex]
[tex]\\ \rm\hookrightarrow 2(2^2-4a+a^2)-2[/tex]
[tex]\\ \rm\hookrightarrow 2(4-4a+a^2)-2[/tex]
[tex]\\ \rm\hookrightarrow 8-8a+2a^2-2[/tex]
