(5-3i)+(4+2i) what is the solution ?​

Answer:

4.5

Step-by-step explanation:

Given the expression ab-0.5

We are to evaluate the expression if a =1 and b = 5

ab- 0.5

=  1(5) - 0.5

= 5 - 0.5

= 4.5

Hence the required result is 4.5

Answer:

2. 24

3. 32.5

Step-by-step explanation:

base ∙ height

–––––––––– = answer

         2      

Just plug in your base number and height number and multiply, then divide by 2.

Answer: b, d

Step-by-step explanation:

Corresponding angles are formed when two parallel  straight lines are cut by a transversal

[tex]\angle b=62^{\circ}[/tex]

In the figure, [tex]\angle d\ \text{and}\ 62^{\circ}[/tex] are alternate angle

[tex]\therefore \angle d=62^{\circ}[/tex]

Answer:

x = 34

Step-by-step explanation:

4x + 10 + x = 180

5x + 10 = 180

      -10     -10

5x = 170

divide by 5

x = 34

Answer:

Step-by-step explanation:

add them

Answer:

A

Step-by-step explanation:

Because if you subtract A from A it gets rid of A leaving only B left.

Answer:

Principal = Total ÷ (1 + Rate)^years

That formula is found here: http://www.1728.org/compint2.htm

Principal = 3.000 / (1.03) ^ 15

Principal = 3.000 / 1.5579674166

Principal = $1,925.59

Step-by-step explanation:

Answer:

0.57

Step-by-step explanation:

The 7 is in the hundredths place. Next to it is a 4. 4 does not round up, therefore making the answer 0.57.

Answer:

wow so what's the question then

Answer:

There are no solutions

Step-by-step explanation:

9x+18−5x=2+4x

Step 1: Simplify both sides of the equation.

9x+18−5x=2+4x

9x+18+−5x=2+4x

(9x+−5x)+(18)=4x+2(Combine Like Terms)

4x+18=4x+2

4x+18=4x+2

Step 2: Subtract 4x from both sides.

4x+18−4x=4x+2−4x

18=2

Step 3: Subtract 18 from both sides.

18−18=2−18

0=−16

Answer:

There aren't any values of x that would make the equation true.

NO SOLUTION

Answer:

the simple interest rate is 18.00%

Step-by-step explanation:

The computation of the simple interest rate is shown below:

Amount = Principal × (1 + rate)^years

$4,935 = $3,000 × (1 + rate)^3

After solving it, the rate of percentage is 18.00%

Hence, the simple interest rate is 18.00%

At the end of 20 years, your savings will have grown to $382,701.

You will have earned in $300,481 in interest.

Answer:

Step-by-step explanation:

Multiply the numerator and denominator by 7×2 = 14 to eliminate the denominators of those fractions:

[tex]\dfrac{\dfrac37}{\dfrac{7\sqrt{10}}2}\times\dfrac{14}{14}=\dfrac{3\times2}{7\sqrt{10}\times7}=\dfrac6{49\sqrt{10}}[/tex]

Rationalize the denominator by multiplying both numerator and denominator by √10:

[tex]\dfrac6{49\sqrt{10}}\times\dfrac{\sqrt{10}}{\sqrt{10}}=\dfrac{6\sqrt{10}}{49(\sqrt{10})^2}=\dfrac{6\sqrt{10}}{49\times10}=\dfrac{6\sqrt{10}}{490}[/tex]

Lastly, cancel the common factor of 2 in both the numerator and denominator (which comes from 6 = 2×3 and 490 = 2×245):

[tex]\dfrac{6\sqrt{10}}{490}=\dfrac{3\sqrt{10}}{245}}[/tex]

Answer:

b + 1.75f

Step-by-step explanation:

1.75 cups are used for every loaf of pumpkin bread.

Answer:

f(4/7)=b

Step-by-step explanation:

3+1/2=7/2

(7/2)x=2

x=4/7

the constant of the equation is 4/7

so take f and b and put f in place for 7/2 cups and b for 2 loaves of bread.

f(4/7)=b

Answer:

8,5

Step-by-step explanation:

x-y=3

x+y=13

2x=16

x=8, y=5

Answer: 8 and 5

Step-by-step explanation:

x - y = 3

x + y = 13

------------------ (add the two equations)

2x = 16

x = 8

8 + y = 13 (substitute x as 8 into one of the equations)

y = 5

Given:

The sides of a triangle are 3 cm, 5 cm, 7 cm.

To find:

The angle classification of the given triangle.

Solution:

Let a,b,c are the three sides of a triangle ABC, where c is the longest side.

1. Triangle ABC is acute, if [tex]c^2<a^2+b^2[/tex].

2. Triangle ABC is acute, if [tex]c^2=a^2+b^2[/tex].

3. Triangle ABC is acute, if [tex]c^2>a^2+b^2[/tex].

The sum of square of two smaller sides is

[tex]3^2+5^2=9+25[/tex]

[tex]3^2+5^2=34[/tex]

In the given triangle 7 cm is the longest sides. So,

[tex]7^2=49[/tex]

It means,

[tex]7^2>3^2+5^2[/tex]

Since [tex]c^2>a^2+b^2[/tex], therefore, the triangle ABC is an acute triangle.
