4 and 2 5ths + 2 and 2 3irds =

Answer:

a

Step-by-step explanation:

because you can't divide by 2 yet

The first step is Add 8 to both sides of the equation

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

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:

2x - 8= 20

Now, first step to solve the equation is

Add 8 on both side

2x- 8 +8 = 20 + 8

2x= 28

and, divide both side by 2

x= 28/2

x= 14

Hence, the first step is Add 8 to both sides of the equation

Answer:

a) 1/3

b) 7/9

Step-by-step explanation:

A) there are 18 total, 6/18 is 1/3

B) there are 18 total, you add the red and green together to get 14, 14/18 is 7/9

B) Side length of B to side length of C is 4:5.

Perimeter of C is 280, so let's put that into the side length of C's place:

4:280

But the 4 also would have to change so let's figure out how much we multiplied 5 by to get 280:

280 / 5 = 56

So let's do 4 x 56 = 224

Our new ratio is 224:280

Therefore the perimeter of mirror B is 224cm.

C) Side length of A to side length of B is 3:4.

We know the perimeter of B from the previous part (224) so let's put that in the 4s place:

3:224

But we also have to change 3, so let's figure out how much we multiplied 4 by to get 224:

224 / 4 = 56

Therefore to determine A's perimeter we do 3 x 56 = 168.

Mirror A's perimeter is 168cm.

D) The side length of mirror A is the perimeter divided by 4 (as they are squares).

168 / 4 = 42. Side length of mirror A is 42cm.

E) Area of a square is side length squared, so the area of mirror A is 42².

42² = 1,764cm².

Answer:

Supplementary angles,

x = 50

Step-by-step explanation:

These angles are supplementary, meaning that they add up to form a 180-degree angle or a straight line.

Knowing this, now form and solve the equation,

76 + 2x + 4 = 180

Combine like terms,

76 + 2x + 4 = 180

80 + 2x = 180

Inverse operations,

80 + 2x = 180

-80           -80

2x = 100

Answer:The solution to a system of linear equations is the point at which the lines representing the linear equations intersect. Two lines in the x y xy xy -plane can intersect once, never intersect, or completely overlap.

A system of linear equations is usually a set of two linear equations with two variables. x + y = 5 x+y=5 x+y=5x, plus, y, equals, 5 and 2 x − y = 1 2x-y=1 2x−y=12, x, minus, y, equals, 1 are both linear equations with two variables. When considered together, they form a system of linear equations.

a numerical or constant quantity placed before and multiplying the variable in an algebraic expression.

a constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. For example, in the quadratic polynomial the 3 is a constant term.

Answer:

It would travel 320 miles in 8 hours

Step-by-step explanation:

200 divide by 5 equals 40

40 x 8= 320

Answer: 320 miles

You divide 200 from 5, which gives you 40. Then, you multiply 40 times 8, giving you 320.

Answer: m<10 less than 10 is the answer so it would be m<10

Step-by-step explanation:

for the anaconda  5.23 + 1.27 m  where m is the number of months,  and the total length is in meters

The anaconda starts at 5.23 meters and grows 1.27 meters each month for m months

for the python 4.76 + 2.04m   where m is the number of months, l is the length of the python in meters

The python starts at 4.76 meters and grows 2.04 meters each month for m months

5.23 + 1.27 m  = 4.76 + 2.04m   m is the number of months  Each side is
