The value of the expression is 31.5.
To evaluate the given expression, we'll follow the order of operations (PEMDAS/BODMAS):
1. Perform the operations inside parentheses/brackets first.
2. Then, calculate the exponents/powers.
3. Finally, perform any multiplication and division from left to right.
Given expression: 7 1/4 × 2² + (8 1/2 - 2) ÷ 3
Step 1: Perform operations inside the parentheses/brackets:
8 1/2 - 2 = 7 1/2
The expression now becomes: 7 1/4 × 2² + 7 1/2 ÷ 3
Step 2: Calculate the exponents:
2² = 2 ×2 = 4
The expression now becomes: 7 1/4 × 4 + 7 1/2 ÷ 3
Step 3: Perform multiplication and division from left to right:
7 1/4 × 4 = 7.25 × 4 = 29
7 1/2 ÷ 3 = 7.5 / 3 = 2.5
The final expression now becomes: 29 + 2.5
Step 4: Perform addition:
29 + 2.5 = 31.5
Therefore, the value of the expression is 31.5.

How should the decimal point in 0.937 change to get the correct answer to 0.937 ÷ 10²?
A. move it 2 place to the right
B . move it 2 places to the left
C .move it 3 places to the right
D .move it 3 places to the left
Answer:
B.
Step-by-step explanation:
When moving a decimal point 2 places to the right you are multiplying. When moving it to the left you are dividing. In this case we are moving 2 places to the left which the exponent 2 is representing. If you were to move 3 places to the right or left you would need to have a three as your exponent.

Answer:
3x
Step-by-step explanation:
the distance between 0 and C = x
to make b 3 times distance of c to 0 we should multiply by 3
so X × 3 = 3X
if the distance of c to 0 equal to 1 cm means that x = 1
3x = 3
so be should place b 3 cm away from 0

Answer:
1. x = -7
2. n = 9
3. x = -2
Step-by-step explanation:
5x + 3 = -32
-3 -3
5x = - 35
÷ 5 ÷ 5
x = -7
__________________________________________________________
4 + [tex]\frac{n}{3}[/tex] = 7
-4 -4
[tex]\frac{n}{3}[/tex] = 3
× 3 × 3
n = 9
__________________________________________________________
x - 4/ 3 = -2
( x − 4 ) ⋅ 2 = 3 ⋅ ( x - 2 )
2x - 8 = 3x - 6
-2x -2x
-8 = x - 6
+ 6 +6
-2 = x

Answer:
1: -7 2: 9 3: -2
Step-by-step explanation:
First Equation. (You first want to isolate the variable)
5x + 3 = -32 (subtract 3)
-3 -3
5x = - 35 (divide by five)
x = - 7
Second Equation. (Isolate variable)
4 + n/3 = 7 (subtract four by each side to get rid of it on the variable's side)
-4 -4
n/3 = 3 (isolate n, so mutiple each slide by 3)
n = 9
Third Equation. (isolate again)
x-4/3 = -2 (mutiple each side by three to get rid of the three on variables side)
x-4 = -6 (add four to each side to cancel out four on the variables side)
x=-2

Step-by-step explanation:
Answer:
2b + 9 = ?
Step-by-step explanation:
First you do commutative property, meaning you switch the numbers with ones they correspond to.
(3b-b)+(7+2)=
Then you find the sum/difference.
2b + 9 =
Since b has no number with it, just count it as a one for now. You would then do a one step equation. This would be the equation simplified.

Respond to the questions about the first recipe:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
