i don't understand anything what grade are you in

Step-by-step explanation:

Step-by-step explanation:

(4x-6)+(8x+18) = 180°

12x+12 = 180

12x=168

x=14°........ ..(1)

8x+18=y+3.. (putting the value of x from equation1)

72+18-3=y

y= 87°

hope this helps you.

Step-by-step explanation:

2y+7-5y+6y-3+y=

(2-5+6+1)y +7-3 =

(4)y + 4 =

4y + 4

the others could be:

9y-5+9-5y

and

4y-1+2y-y-y+1+4

Answer:

B. y – 270 = 45(x – 2) ; $450

Step-by-step explanation:

In February, you have a balance of $270 in your bank account.

In January, you have a balance of $270 - $45 = $225 in your bank account.

In December, you have a balance of $225 - $45 = $180 in your bank account.

y = $180 + $45x, where x = 1, 2, 3, 4...

Balance in June: x = 6

y = $180 + $45x = $180 + $45×6 = $180 + $270 = $450

The complete question is:

In February, you have a balance of $270 in your bank account. Each month you deposit $45. Let January = 1, February = 2, and so on. Write an equation for this situation. Use the equation to find the balance in June.

Answer:

$450 in June

Step-by-step explanation:

$X = 270 + 45 × ( number of month)  

In this problem, February, the month you start with, would be month 0.

June would be 4.

$X = 270 + 45 × 4

= 270 + 180

= $450 in June

$450 in June.

Answer:

x = -1

Step-by-step explanation:

3(x + 2) = 2x + 5

Use the distributive property on the left side.

3x + 6 = 2x + 5

Subtract 2x from both sides. Subtraction property of equality.

x + 6 = 5

Subtract 6 from both sides. Subtraction property of equality.

x = -1

Answer: 1

Step-by-step explanation: 3(x+2)=2x+5

                                               3x+6=2x+5

                                                -3x   -3x

                                                    6=1x+5

                                                     -5     -5

                                                       1=1x

Answer:

31710786

Step-by-step explanation:

IF you meant it to convert into digits.

Problem 10, Part A

The larger outer square is x cm by x cm, where x is some placeholder for a positive number. For example, if x = 10, then we have a 10 cm by 10 cm square.

Unfortunately, we don't know what number replaces x.

What we can determine is the connection between the larger square and the smaller one. The frame is 3 cm wide in all directions (aka it's a uniform width). What this allows for is that the smaller square is x-6 by x-6. The 6 is from subtracting two copies of 3, so ultimately we're subtracting off 2*3 = 6 to form the smaller dimensions.

You can think of it like x-3-3 = x-6

So we need to expand out (x-6)(x-6) like so

(x-6)(x-6)

y(x-6)

xy - 6y

x(x-6) - 6(x-6)

x^2-6x - 6x+36

x^2-12x+36

In the second step, I replaced one copy of (x-6) with y, after which I used the distributive rule. After distributing, I plugged in y = x-6 and distributed again. The last step is combining like terms. As an alternative, you can use either the box method or the FOIL rule to find the answer.

The expression x^2-12x+36 is the expanded form of the area of the smaller square, which is the picture itself without the frame involved.

===========================================================

Problem 10, Part B

We follow the same idea as the previous part. This time, we have a rectangle that isn't a square.

Along the horizontal, the (x+30) will drop to (x+30)-5-5 = x+20 when we consider just the picture without the frame. In other words, the smaller inner rectangle has a horizontal dimension of (x+20) cm.

The vertical component of this smaller rectangle is x-5-5 = x-10 cm

So,

area = length*width

area = (horizontal dimension)*(vertical dimension)

area = (x+20)(x-10)

area = y(x-10) ..... let y = x+20

area = xy - 10y ...... distribute

area = x(x+20) - 10(x+20) ... plug in y = x+20

area = x^2+20x - 10x - 200 ..... distribute again

area = x^2 + 10x - 200

Side note: the units for this area, and for part A, are in square cm.

Answer:

x=7/6

Step-by-step explanation:

subtract the 4x from both sides of the equation

(2x+6)-4x=4x-3-4x

find common denominator

(2x+6)/5+(5(-4)x)/5=4x-3-4x

then combine fractions

(2x+6+5(-4)x)/5=4x-3-4x

then multiply the 5&4

(2x+6-20x)/5= 4x3-4x

combine terms

(-18x+6)/5= -3

then multiply everything by 5

-18x+6= -15

subtract the 6 from both sides

-18x= -21

divide -21 by -18

(-21)/(-18)=x

find greatest common multiple (3) and solve

x = 7/6

Answer:

0.625

Step-by-step explanation:

................

First draw a straight line and plot the four points A,B,C,D on that line. It doesn't matter where you plot the points as long as they are in order and none overlap.

We're given AD = x+203. We also know that BD = x+127. Since AB + BD = AD (segment addition postulate) we can determine the length of AB

AB + BD = AD

AB + BD-BD = AD-BD Subtract BD from both sides.

AB = AD-BD

AB = (x+203)-(x+127)

AB = x+203-x-127

AB = 76

The length of BC is also 76 (given). So,

AB+BC = 76+76 = 152

this is equal to the length of AC because AB+BC = AC

So, AC = 152 units

Final Answer: 152 units

Answer:

1/2

Step-by-step explanation:

Answer:

0.08

Step-by-step explanation:

5 ^-2 * cube root of 8

first of all, let us solve 5^-2

using the law of indices;

a^-2 = 1 / a ^2

following this law, we have;

5^-2 = 1 / 5^2

we know that 5^2 = 25

therefore,

5^-2 = 1 / 25

now, let is continue by solving the cube root of 8

now, there are three ways of solving this;

we could just simply think of any number that when multiplies itself three times times, it gives 8, or we could just simply use a calculator

regardless of what we use, we have to end up with the number 2 as the answer

leading is to our conclusion.

from all our solution, we have reduced our question to;

1 / 25 ( which is 5^-2) * 2 ( which is the cube root of 8 )

= 1 / 25 * 2 / 1

note that 2 is the same as 2 / 1. We put it like this when we want to carry out an operation on an integer ( e.g. 2) and and a fraction ( e.g. 1 / 25 )

so,

1 / 25 * 2 / 1 =

2 / 25 ( the two multiplies the 1 in 1 / 25 and the 25 multiplies the 1 in 2 / 1)

leaving our answer in decimal, we have;

0.08
