What is the correct answer?

Answer:

Step 6 is done by Additive Property of Equality, also known as Compatibility of Equality with Addition, which is defined by the following expression:

[tex]a = b \to a + c = b + c[/tex], [tex]\forall\,a,b, c\,\in \,\mathbb{R}[/tex]

[tex]a = b \to a + c = b + c[/tex], [tex]\forall\,a,b, c\,\in \,\mathbb{R}[/tex]

1) [tex](7\cdot x - 3) + 3 = (2\cdot x + 7) + 3[/tex] Associative property/Compatibility with addition

2) [tex]7\cdot x + [3 + (-3)] = 2\cdot x + (7 + 3)[/tex] Associative and commutative properties/Definition of subtraction

3) [tex]7\cdot x + 0 = 2\cdot x + 10[/tex] Existence of the additive inverse/Definition of addition

4) [tex]7\cdot x = 2\cdot x + 10[/tex] Modulative property/Result

Answer:

275%

Step-by-step explanation:

Given that,

Initial weight of the puppy = 600 grams

Final weight of the puppy = 2250 gram

We need to find the percent increase in the puppy's weight.

Increase in weight = 2250 gram - 600 grams

= 1650 grams

The percentage of increase in weight,

[tex]\%=\dfrac{1650}{600}\times 100\\\\=275\%[/tex]

So, the required increase in puppy's weight is equal to 275%.

Answer: 6 sticks

Step-by-step explanation:

Given

Joe needs [tex]\frac{3}{4}[/tex] butter for each cake

One stick of butter is equivalent to 0.5 cup

So, joe need

[tex]\dfrac{3}{4}\times \dfrac{1}{2}=\dfrac{3}{8}\ \text{cup}[/tex]

for each cake

To bake 8 cakes, it is

[tex]\Rightarrow \dfrac{3}{4}\times 8=6\ \text{sticks}[/tex]

Answer: 21

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

4(-3x + 8) = -16

Divide both sides by 4

-3x + 8 = -4

Subtract 8 from both sides

-3x = -12

Divide both sides by -3

x = 4

Answer:

$49.5

Step-by-step explanation:

y = -x^2 + 99x - 932

The maximum point is :

dy/dx = 0

Take the first derivative of y

dy/dx = - 2x + 99

Put - 2x + 99 = 0

-2x = - 99

x = 99 / 2

x = 49.5

Hence, To make maximum profit, widget should be sold at $49.5 per widget.

Answer:

Part A:

1 book -- $7.25

9 books -- (9 * 7.25) = $65.25

And shipping fee -- (65.25 + 6.75) = $ 72

Part B

9 multiplied by the cost and added with the shipping fee to get Hannah's total cost.

Answer:

19.09 = 19.1

Step-by-step explanation:

we can split the square into two right triangles. Becasue the perimeter of the square is 54cm, we know the each side is 13.5 cm (54cm / 4). Using the pythagoras theorem, the diagonal is 19.1 cm.

Answer:

0 ≤ x ≤ 2 (i assumed that the arrows included 0 and 2).

Step-by-step explanation:

One arrow shows 0 and greater (as it is pointing right) and the other shows 2 and smaller (as it is pointing left). The arrow pointing right has the equation of:

x ≥ 0 (where x is a random number)

The arrow pointing left has the equation of:

x ≤ 2 (where x is a random number)

Assuming that you need to find an equation so that x fits both inequalities, we combine them into one inequality and get:

0 ≤ x ≤ 2

Answer:

The standard repayment plan.

Step-by-step explanation:

Here is the complete question :

SARAH makes $43,000 per year, is single, and lives in Connecticut. She has $19,000 in subsidized loans and $8000 in unsubsidized loans. Which repayment plan will be the cheapest for her in total?

The standard repayment plan is a repayment plan where a fixed sum is paid monthly for 10 years. This makes a total of 120 payments. The advantage of the standard repayment plan over the federal repayment plan is that less interest is paid and payment is made over a shorter period

Because unsubsidized loans accrue a higher interest expense when compared to subsidized loans, Sarah should pay off her unsubsidized loan first. This would minimise interest payment

Answer:

length = 10 inches

Step-by-step explanation:

We know that the perimeter of a rectangle:

P = 2(L + W), where p= perimeter, L = length, W= width, so:

34 = 2(L + 7)

=> 34 = 2L + 14

=> 20 = 2L

=> 20/2 = L

=> 10 = L
