Step-by-step explanation:

taking that blank as x

5/2 -x = 1/3

the x will go to the right hand side of the equation which then would make it positive ( making x the subject) and 1/3 will come to the left hand side of the equation becoming -1/3

so the equation will become 5/2-1/3=x

solving the fraction then gives 13/6 or 2.17 as the value of x

The value of the equation is x = 13 / 6

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the unknown number be represented as x

Substituting the values in the equation , we get

( 5/2 ) - x = 1/3   be equation (1)

Adding x on both sides of the equation , we get

( 5/2 ) = ( 1/3 ) + x

Subtracting ( 1/3 ) on both sides of the equation , we get

x = ( 5/2 ) - ( 1/3 )

On simplifying the equation , we get

x = ( 15 - 2 ) / 6

x = 13 / 6

Therefore , the value of x is 13/6

Hence , the equation is x = 13/6

Answer:

The address of Ainsley is 24 and that of Lane is 25.

Step-by-step explanation:

All the houses on sequence lane have an address whose numerical portions are greater than that of the prior house.

Now, if Ainsley and Lane are next-door neighbors and the sum of the numerical portions of their addresses is 49.

Let the Ainsley has the address with numeric portion x, then Lane has the address with numeric portion x + 1.

Therefore, x + (x + 1) = 49

⇒ 2x = 48

⇒ x = 24

So, the address of Ainsley is 24 and that of Lane is 25. (Answer)

Answer:

∠RUS = 90°

Step-by-step explanation:

PT is a line. This means that it has a measure of 180°

This means that all of the angles that it is broken up into must add together to equal 180°.

In this case, ∠PUQ +∠QUR +∠RUS +∠SUT =  180°

As we have the measures for all of the angles aside from ∠RUS, we can solve for that

First, let us input each of the measures of the angles

39+23+∠RUS+28=180

Now all we need to do is isolate ∠RUS by subtracting everything to the other side

Once that is done, we get

∠RUS = 90°

Answer:

Answer:

Harry rides further.

Step-by-step explanation:

First, you have to find the least common denominator of 8 and 5, which is 40.

3*5=15, 2*8=12

Hope this helps!!!

Karen rides farther.

Comparing numbers in math is defined as a process or method in which one can determine whether a number is smaller, greater, or equal to another number according to their values.

Given that, Harry rides his bike 25 3/8 miles. Karen rides her bike 25 2/5 miles, we are asked to find who rides farther,

Harry's distance = 25 3/8 = 203/8

Karen's distance = 25 2/5 = 127/5

Subtracting Harry's distance by Karen's distance,

203/8 - 127/5

= 1015-1016/40

= -1/40

Since, the result is in minus that means 127/5 is greater than 203/8.

Therefore, Karen's covers more distance than Harry.

Hence, Karen rides farther.

He invested $6500 in bonds

Step-by-step explanation:

The formula of the simple interest is I = Prt, where

Assume that Mike invested $x in stocks and $y in bonds

∵ Mike invested $x in stocks

∵ Mike invested $y in bonds

∵ Mike invested a total of $25,000

∴ x + y = 25000 ⇒ (1)

∵ The interest rate of the stocks is 7%

∴ r of the stocks = 7 ÷ 100 = 0.07

∴ I (stocks) = x(0.07)(1)

∴ I (stocks) = 0.07x

∵ The interest rate of the bonds is 11%

∴ r of the bonds = 11 ÷ 100 = 0.11

∴ I (bonds) = y(0.11)(1)

∴ I (bonds) = 0.11y

∵ Mike earned $2010 interest on his investments

- Equate the sum of I (stocks) and I (bonds) by 2010

∴ 0.07x + 0.11y = 2010 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -0.11 to eliminate y

∵ -0.11x - 0.11y = -2750 ⇒ (3)

- Add equations (2) and (3)

∴ -0.04x = -740

- Divide both sides by -0.04

∴ x = 18500

- Substitute the value of x in equation (1) to find y

∵ 18500 + y = 25000

- Subtract 18500 from both sides

∴ y = 6500

∵ y represents the amount of money he invested in bonds

∴ He invested $6500 in bonds

He invested $6500 in bonds

The scatterplot that has a stronger correlation is B.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The correlation coefficient helps us to know how strong is the relation between two variables.

The value is always between +1 to -1, where, the numerical value shows how strong the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.

1 indicates a strong positive relationship.

-1 indicates a strong negative relationship.

A result of zero indicates no relationship at all, therefore, an independent variable.

Since the scatterplot is the relationship between the two variables and as in the first graph the value of a single x can return multiple values for y.

Therefore, the scatterplot that has a stronger correlation is B.

No solution

Step-by-step explanation:

To eliminate is to get rid of one of the variables.

You can choose to either add each term in the equations or subtract each term in the equation.

For a variable to be eliminated, there must one pair that have the same constant with it. Each equation already has the same constant with a variable.

Try adding them.

.     y - x = 15

+    y - x = 5

2y - 2x = 20   No variables were eliminated.

Try subtracting.

.     y - x = 15

-     y - x = 5

0y - 0x  = 10   All variables were eliminated.

.         0 = 10     This is false.

Answer: $22,241.32 APEX

Final answer:

By calculating the present value of an annuity using the monthly payment, interest rate, and number of payments, we find that Bryce can afford a car with a value of approximately $22,241.32.

Explanation:

To calculate the value of the most expensive car Bryce can afford based on a $350-per-month car payment with a 6-year loan at an APR of 4.2%, compounded monthly, we use the formula for the present value of an annuity:

PV = PMT × ¶ [(1 - (1 + r)^-nt) / r]

Where:

PV = Present Value (what we're solving for, the cost of the car)

PMT = Monthly Payment ($350)

r = monthly interest rate (APR divided by 12)

n = number of times the payment is made per year (12)

t = number of years (6)

Given:

APR = 4.2% per year or 0.042

Monthly interest rate, r = 0.042 / 12 = 0.0035

nt = 12 × 6 = 72 payments in total

Now we substitute the given values into the formula:

PV = $350 × [(1 - (1 + 0.0035)^-72) / 0.0035]

PV = $350 × [(1 - (1 + 0.0035)^-72) / 0.0035]

PV ≈ $350 × [(1 - (1.0035)^-72) / 0.0035]

Using a calculator to find (1.0035)^-72 and then the whole expression, we get:

PV ≈ $350 × 60.4774

PV ≈ $21,167.09

The value that's closest to our calculation and offered in the options is $22,241.32, so the most expensive car Bryce can afford is approximately $22,241.32.
