Answer:

X¹= -2 + 2√33

X²= -2 - 2√33

Step-by-step explanation:

X × (X+2) = 32

X² + 2X = 32

X² + 2X - 32= 0

Δ=132

X= -2 ± 2√33

X¹= -2 + 2√33

What is 3/5 written as a percent? A. 6% B. 30% C. 60% D. 167%

Answers

Answer:

60%

Step-by-step explanation:

It is 60% because, First we have to make 3/5 a percent so we do 5 times 20 which is 100, and 3 times 20 which is 60. So it total it is 60/100 which is 60%

Answer:

[See Below]

Step-by-step explanation:

_________________________________

✦ An easier way of doing this is to change the fraction to an equivalent fraction:

[tex]\frac{3}{5}[/tex] ≅ [tex]\frac{6}{10}[/tex] ≅ [tex]\frac{60}{100}[/tex]

✦ So now it's easier to change to a percentage.

[tex]\frac{60}{100} =60\%[/tex][tex]60[/tex] percent of [tex]100[/tex]

_________________________________

So your answer would be:

[tex]\bold6\bold0\bold\%[/tex]

Answers

Answer:

0, 5, 18, 22, 100

Step-by-step explanation:

Order the integers from least to greatest which means that the smallest number to the biggest number. Since the biggest number is 100 it goes at the end and 0 is the smallest number so it goes at the end. After that, all you have to do is find which numbers are bigger and smaller. So, the numbers should go in this order 0, 5, 18, 22, 100.

3x + 10+ 2x =50 isks

Answers

Answer:

x = 8

Step-by-step explanation:

3x + 10+ 2x =50

5x = 50 - 10

x = 40/5

x = 8

The value of x would be equal to 8.

We know that equation is an expression that shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.

We are given the equation as;

3x + 10+ 2x =50

Now solve for x;

3x + 10+ 2x =50

Combine like terms;

5x = 50 - 10

x = 40/5

x = 8

The solution will be 8.

Move the numbers to the lines to order them from least to greatest

Answers

Answer:

-3/2, 1.25, |-9/4|, 2.5, 121

Step-by-step explanation:

Convert all numbers to a decimal

-3/2 = -1.5

|-9/4| = 2.25

2.5 = 2.5

121 = 121.0

1.25 = 1.25

Now put them in order from least to greatest.

-3/2, 1.25, |-9/4|, 2.5, 121

The numbers to the lines to order from least to greatest; -3/2, 1.25, |-9/4|, 2.5, 121

How can we express numbers belonging to decimal numeral system?

Suppose that the number is abcd.efg and belongs to the decimal numerical system.

Remember one thing that the place on the left of decimal point is called ones. Move one-one places to right, and divide by 10 and 10 more and more.

Convert all the numbers to a decimal

-3/2 = -1.5

|-9/4| = 2.25

2.5 = 2.5

121 = 121.0

1.25 = 1.25

Now put them in order from least to greatest, we get;

-3/2, 1.25, |-9/4|, 2.5, 121

Step-by-step explanation:

because the straight line is 180 so if you add 35+55=90 and 90+90=180

Answer:

35°

Step-by-step explanation:

What I did was look at ∠ABC and know that collinear is a straight line, and that a straight line is equal to 180°. Then I saw that ∠ABD was a right angle or 90° and that ∠BCE was equal to 55°, so I added those 2 together and got 145°. then I subtracted that from the 180°. because that is what a straight line equals and I got 35°. So, I would say ∠DBE is equal to 35°.
