Answer:

w = 6

RS = 13

Step-by-step explanation:

RS + ST = RT

(2w + 1) + (w - 1) = 18

3w = 18

; w = 6

Hence the value of RS = 2(6) + 1

; RS = 13

AC = AB + BC

56 = (x + 16) + (5x + 10)

56 = 6x + 26....then rearrange the equation to form...;

56 - 26 = 6x

30 = 6x...

where...; x = 5

AB = 5 + 16 and BC = 5(5) + 10

;AB = 21 ;BC = 35

Answer:

(-15, 13)

Step-by-step explanation:

-3(8x + 9y = -3)

4( 6x + 7y = 1)

-24x - 27y = 9

24x + 28y = 4 (add both equations)

y = 13

6x + 7*13= 1

6x + 91= 1

6x = 1 -91

x = -91/6

x = -15

Julian saved between $ 30 and $ 52 over the summer. His friend Daniela saved twice as much. Let n represent the amount of money

Y = (30 + 52) * 2

Y = (82) * 2

Y = 164

Daniela saved $164

What is 4 1/2 pint to quart?

Ivanshal [37]

There are two pints every quarter.

So let's convert pints to quarter

$\frac{4\frac{1}{2} }{2} =\frac{\frac{9}{2} }{2} = \frac{9}{4}$

There 4 1/2 pint is to 9/4 quarter.

Hope that helps!

p.s. look at my diagram to help you remember

What are the powers of 4 through 1000

Ahat [919]

Answer:

{4^0, 4^1, 4^2, 4^3, 4^4}, or, with a bit of rounding off,

{4^0, 4^1, 4^2, 4^3, 4^4, 4^5} = {1, 4, 16, 64, 256, 1024}

Step-by-step explanation:

I wanted to determine the largest power of 4 that does not exceed 1000. Here's what I did:

4^x = 1000. Taking the ln of both sides, we get x ln 4 = ln 1000.

6.9078

Solving for x: x = --------------- = 4.98

1.3863

Thus, the answer to this question is {4^0, 4^1, 4^2, 4^3, 4^4}. If you're willing to talk in terms of approximations, then there'd be one more power of 4 in this set: 4^5. Note that 4^5 = 1024, whidh is just a bit over 1000.

98 Points!<br><br> (3x^2^a - 4y^a z^3a )^2

vfiekz [6]

((3x^2)^a - (4y^a)(z^3a))^2

First, expand.

((3x^2)^a - (4y^a)(z^3a)) ((3x^2)^a - (4y^a)(z^3a))

Combine

3^(2a) - x^(4a) - 8 * 3^(2a)x^(2a)y^(a)z^(3a) + 16y^(3a)z^(6a)

hope this helps
