Subtract 76 on both sides:

2401 - 76 = 76 - 2x - 76

2325 = -2x

Divide both sides by -2:

-1162.5 = x

Answer:

x = 52

Step-by-step explanation:

∡RQS = 180 - (90 + 34)

∡RQS = 56°

∡PQS + ∡RQS = 180°

∡PQS = x + 72

x + 72 + 56 = 180

x + 128 = 180

x = 52

Which expression is equivalent to 64y18 – 1000z6?

natta225 [31]

Answer:

$(4y^{6})^{3}-(10z^{2})^{3}$

Step-by-step explanation:

we have

$64y^{18}-1000z^{6}$

we know that

$64=4^{3}$

$y^{18}=(y^{6})^{3}$

$1000=10^{3}$

$z^{6}=(z^{2})^{3}$

Substitute the values in the expression

$(4^{3})((y^{6})^{3})-(10^{3})((z^{2})^{3})$

$(4y^{6})^{3}-(10z^{2})^{3}$

The path of a skateboarder along a ramp at a new skate park is shown below, where the starting position is on the left side of t

Ugo [173]

Answer:

The answer is A. Please vote brainliest

Step-by-step explanation:

On the graph in plato the y axis starts on 8, so that is our initial height. the graph starts to go lower to ground level until it reaches the 12 on the x axis, this is where the skateboarders would meet ground level on the ramp, and obviously the graph is all positive numbers so the start of the ramp would be on the left edge.

(x-5)(-3)=18<br><br> ??? I need help

svet-max [94.6K]

Answer:

x = - 1

Step-by-step explanation:

Given

(x - 5)(- 3) = 18

Divide both sides by - 3

x - 5 = - 6 ( add 5 to both sides )

x = - 1

distribute the left side by - 3

- 3x + 15 = 18 ( subtract 15 from both sides )

- 3x = 3 ( divide both sides by - 3 )

x = - 1

How many five-digit numbers are there that do not have two consecutive digits the same? For example, you would count 12104 and 1

WARRIOR [948]

We can choose the first digit in any of 9 ways, 1,2,3,4,5,6,7,9 or 9 .

We can then choose the second digit in any of the 9 ways, 0 or any of 8 ways not chosen for the first digit.

We can then choose the third digit in any of the 9 ways, other than the second digit.

We can choose the fourth digit in any of the 9 ways, other than the third digit.

And we can choose the fifth digit in any of the 9 ways, other than fourth digit.

Hence number of ways = 9*9*9*9*9 = $9^{5} = 59049$

So, total number of five digit numbers which don't have consecutive digits same is 59049.
