what number makes the equation true

Answers

Answer: the answer is -2 1/3

Step-by-step explanation: it would be -2 1/3 because 5 + 2=7 and then add the 1/3 to make -7 1/3

The number that makes the equation

[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]     true is [tex]\rm \bold {-2\dfrac{1}{3} }[/tex].

So option 4 is correct.

Let the number that makes equation true is x

The question is that what makes equation true

[tex]\rm -5 +x = -7\dfrac{1}{3}[/tex]

This equation is a linear expression with one variable and rational numbers.

This equation can be solved in the following way

[tex]\rm -5 +x = -\dfrac{22}{3} \\x = 5 -\dfrac{22}{3} \\x = (15-22)/3 \\x = -7/3\\ x= -2\dfrac{1}{3}[/tex]

So from the given options in figure  we can see that option 4 is correct

If A is a square matrix of order 2, then det(-3A) is *
a. 3 det A
b. -3 det A
c. 9 det A
d. -9 det A
Help please.​

Answers

Answer:

c. 9 det A

Step-by-step explanation:

Given the following data;

Since A is a square matrix of order 2, we know that n = 2

K = 3

For any scalar k;

∣kA∣ = k^{n} ∣A∣

Substituting into the equation;

∣-3A∣ = -3²∣A∣

Simplifying, we have;

∣-3A∣ = 9∣A∣

= 9 detA

Therefore, det (-3A) = 9 detA

Richard invests $230.92 every month into his mortgage. At the end of 30 years, he has a balance of $184,033.06. What interest did he make over 30 years?

Answers

The answer is $101,233.06

Richard made $100,719.46 in interest over 30 years on his mortgage.

To calculate the total interest Richard made over 30 years, we need to find the total amount he invested and then subtract that from the final balance.

Richard invests $230.92 every month for 30 years, which is a total of:

Total investment = 30 years * 12 months/year * $230.92/month

Total investment = $230.92 * 360

Total investment = $83,313.60

Now, we can calculate the interest earned by subtracting the total investment from the final balance:

Interest = Final balance - Total investment

Interest = $184,033.06 - $83,313.60

Interest = $100,719.46

Therefore, Richard made $100,719.46 in interest over 30 years on his mortgage.

Answers

Step-by-step explanation:

1st day: 6 seashells, 14.7 dollars

2nd day: 3 seashells, 7.35 dollars

3rd day: 7 seashells, 17.15 dollars

All together: 39.2 dollars

day 3 = 7

day 2 = 7 - 4 = 3

day 1 = 3 * 2 = 6

total seas shells = 7 + 3 + 6 = 16

total money = 16 * 2.45 = $39.20

Length of PQ

PQ = √(y2-y1)²+(x2-x1)²

From the coordinate;

x1 = -10, y1 = 1, x2 = -10 y2 = -7

Substitute

PQ = √(-7-1)²+(-10-(-10))²

PQ = √(-8)²+0²

PQ = √64

3 folders cost $2.91 dollar sign . Which equation would help determine the cost of 2 folders? WRITE THE LETTER IN THE SPACE BELOW.

Answers

Answer:

$1.94

Step-by-step explanation:

Cost of 3 folders = $2.91

We need to find the cost of 2 folders.

First we will find the cost of 1 folder

1 folder = $2.91/3 = $0.97

To find the cost of 2 folders, multiply $0.97 and 2

2 folders = $0.97 × 2

= $1.94

Hence, the cost of 2 olders is $1.94.
