Answer:

1. 64.5 lbs

2. 52.5 lbs

3. 40lbs

4. 60 lbs

5. 80 lbs

Step-by-step explanation:

To determine how much of a persons weight is water, multiply 3/4 by their weight.

1. weight of water = weight * 3/4

= 86 * 3/4

= 64.5 lbs

2. weight of water = weight * 3/4

= 70 * 3/4

= 52.5 lbs

3. weight of water = weight * 3/4

30 = weight * 3/4

Multiply by 4/3 on each side

30*4/3 = weight *3/4*4/3

40 = weight

4. weight of water = weight * 3/4

45 = weight * 3/4

Multiply by 4/3 on each side

45*4/3 = weight *3/4*4/3

60 = weight

5. weight of water = weight * 3/4

60 = weight * 3/4

Multiply by 4/3 on each side

60*4/3 = weight *3/4*4/3

80 = weight

Could anyone help??????????????

kvasek [131]

Answer:

a. No

b. Yes

c. No

d. Yes

e. Yes

Step-by-step explanation:

3(x+2) simplified is equal to (3)x+(3)2 which is simplified to 3x+6.

a. 3x+2 is not the same as 3x+6 so it is false.

b. 3(2+x) is simplified to (3)2+3(x) which is simplified to 6+3x or 3x+6 which is equal to 3x+6 so it is true.

c. 3x+2x is simplified to 5x which is not equal to 3x+6 so it is false.

d. x+2x+2+4 is simplified to 3x+6 which is equal to 3x+6 so it is true.

e. x+x+x+1+1+1+1+1+1 is simplified to 3x+6 which is equal to 3x+6 so it is true.

can someone help me!! Use algebraic rules of equations to predict the solution type to the system of equations. Include all of y

xz_007 [3.2K]

Answer:

x + y = 4 Equation 1

y = 2x -1 Equation 2

-2x + y = -1

x + y = 4

Subtract

You will get

- 3x = -5

Divide by -3

-3x / -3 = - 5 /-3

x = 5/3

Substitute x into equation 1

x + y = 4

x = 5/3

5/3 + y = 4

y = 4 - 5/3

y = 7/3

x = 5/3 y = 7/3

Hope this helps.

1011+111 in binary form

Ann [662]

Answer:

10010

Step-by-step explanation:

$1011=1(2)^3+0(2)^2+1(2)^1+1(2)^0$

$111=1(2)^2+1(2)^1+1(2)^0$

So $1011+111$ gives us:

$1(2)^3+0(2)^2+1(2)^1+1(2)^0$

$+$

$1(2)^2+1(2)^1+1(2)^0$

-----------------------------------------------------

Combine like terms:

$1(2)^3+(0+1)(2)^2+(1+1)(2)^1+(1+1)(2)^0$

$1(2)^3+1(2)^2+(2)(2)^1+(2)(2)^0$

We aren't allowed to have a coefficient bigger than 1.

I'm going to replace $2^0$ with 1 and $2$ with $(2)^1$ :

$1(2)^3+1(2)^2+(2)^2+(2)^1(1)$

I want a $2^0$ number:

$1(2)^3+1(2)^2+1(2)^2+1(2)^1+0(2)^0$

Combine like terms:

$1(2)^3+2(2)^2+1(2)^1+0(2)^0$

$2(2)^2=2^3$ :

$1(2)^3+2^3+1(2)^1+0(2)^0$

Combine like terms:

$2(2)^3+1(2)^1+0(2)^0$

We can rewrite the first term by law of exponents:

$2^4+1(2)^1+0(2)^0$

$1(2)^4+1(2)^1+0(2)^0$

So the binary form is:

$10010$

Maybe you like this way more:

Keep in mind 1+1=10 and that 1+1+1=11:

Setup:

1 0 1 1

+ 1 1 1

------------------------------

(1) (1) (1)

1 0 1 1

+ 1 1 1

------------------------------

1 0 0 1 0

I had to do some carry over with my 1+1=10 and 1+1+1=11.

Need help on all these questions!!

Yuki888 [10]

Okay, so YZ = 3 cm. You have XM correct. And YM = 0.5.

Now, you have the midpoint M at the correct spot.

Use Pythagorean's theorem o find the length of AB. a² + b² = c² a=6, b=8.

6² = 36 8² = 64 36 + 64 = 100 AB = 10!

If AB = 10 then AM = 5 MB also = 5

If B is the midpoint of AC, C would be 12 rows down from A, and 16 columns to the right. The last spot where the line intersects.

There are your answers!
