The equations best verifies the reasonableness of the solution will be log₃ 2187 = 7 and log₃ (3⁷) = 7. Then the correct options are A and E.

Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.

The equation is given below.

log₃ x = 7

Take anti-log on both side, then we have

x = 3⁷

x = 2187

Then the equation is satisfied by 2187. Then we have

log₃ 2187 = 7

  log₃ (3⁷) = 7

Then the correct options are A and E.

Step-by-step explanation:

Answer:

x=1

y=1

Step-by-step explanation:

y=x^2-x+1        1. Write out the equation

y=y^2-y+1        2. Substitute the "x"s for "y"s

0=y^2-2y+1      3. Subtract "y" from both sides of the equation

0=(y-1)(y-1)        4. Factor into a binomial

y-1=0

y=1

The original amount of the loan of Margo is $1560.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the original amount is x

Given that,

She has already paid $315 and still owes them $1245.

So,

x - 315 = 1245

x = 1560.

Hence "The original amount of the loan of Margo is $1560".

Answer:

90°

Step-by-step explanation:

We need expressions for the measures of the three interior angles. Then we add them and set the sum equal to 180. Then we solve for x. Finally, we use the value of x in x + 100 to find the measure of angle A.

Let's first find an expression for each angle.

Angle A: m<A = x + 100

Bottom left angle: The interior angle is vertical to the angle measuring x + 60, so the interior angle also measures x + 60.

Bottom right angle: Let's call the measure of the interior angle y. y and the angle measuring 140° are supplementary, so y + 140 = 180; y = 40.

Now that we have expressions for the three interior angle measures, we add them and set the equal to 180.

(x + 100) + (x + 60) + 40 = 180

x + 100 + x + 60 + 40 = 180

2x + 200 = 180

2x = -20

x = -10

The measure of angle A is x + 100, and x = -10

m<A = x + 100 = -10 + 100 = 90

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

If you spent 58 minutes doing English homework and 47 minutes doing math homework.

Now,

Since, The time for doing English homework = 58 minutes

And, The time for doing Math homework = 47 minutes

So, The time more to spend doing English homework = 58 - 47

                                                                                   = 11 minutes

Thus, There are 11 minutes more time to spend doing English homework.

Answer:

21.875

Step-by-step explanation:

you do 175 divided by 8

The required number of tables to seat 175 people are 22.

Division is defined as the splitting of a large group into smaller groups such that every group will have an equal number of items.

it is given that,

Number of chairs for 1 table = 8

Number of people to seat =  175

Therefore chairs = 175

Since 8 chairs are required at every round table

Therefore,

Number of tables to seat 175 people = Number of people to seat/Number of chairs for 1 table

⇒ Number of tables to seat 175 people = 175/8

⇒ Number of tables to seat 175 people = 21.87 ≈ 22 tables

Thus, the required number of tables to seat 175 people are 22.

Answer:

The amount is 8,322

Step-by-step explanation:

To get this , we are going to use the compound interest formula

A = P( 1 + r/n)^nt

A is the amount we are calculating

P is the amount deposited = 6,500

r is the interest rate = 5% = 5/100 = 0.05

n is the number of times per year the interest is compounded

= 2 since it is semi-annually

t is the number of years = 5

Substituting these values, we have it that ;

A = 6,500(1 + 0.05/2)^10

A = 6,500(1.025)^10

A = 8,322

Answer:

The one from superstore

Step-by-step explanation:

We are to find the box if cereal that gives us the best value for our money.

We first calculate for cheapstore

We have 500 pounds divide through by 10 = 50p

Multiply 50 with 2

= 100p

= 1 pound

4 pounds = 600 grams

For superstore

Divide 600 g by 10

= 60g

Multiply with 3

= 60g x 3

= 180g

600+180 = 780grams

600grams/4pounds = 150g

780grams / 5 pounds = 156gtams

From here we concise that superstore box has best value

Answer:

Her cake should be 495 grams
