Answer:

The fourth option - t = 3, y = 5

Step-by-step explanation:

-8 + t becomes -5, thus t is 3 since -8 + 3 = -5.

-12 becomes -2y - 2, so we can set these equal to each other as -2y - 2 = -12 and solve from there. Add 2 to both sides, -2y = -10, then divide by -2 on both sides, y = 5.

How many different four-digit numbers can be made using the digits 1,2,3,4,5,6 if no digit can be used more than once?

igomit [66]

Answer:

360

Step-by-step explanation:

The given digits are 1,2,3,4,5,6.

So, total number of digits = 6.

We need to find the number of different ways to form four-digit numbers using the digits, without repetition.

Total ways for first place = 6

After selecting 1 digit the number of remaining digits is 5. So,

Total ways for second place = 5

Similarly,

Total ways for third place = 4

Total ways for forth place = 3

Total number of ways = $6\times 5\times 4\times 3=360$

Therefore, 360 four digit numbers are possible.

Please help me I’m stuck

Answer:

$x = 3.7$

Step-by-step explanation:

We can find the side of the hypotenuse by applying pythagorean theorem.

${5}^{2} + {5}^{2} = {x}^{2}$

$25 + 25 = {x}^{2}$

$50 = {x}^{2}$

$x = 5 \sqrt{2}$

Now we can apply pythagorean theorem on the other triangle

$(5 \sqrt{2} ) {}^{2} + {x}^{2} = {8}^{2}$

$50 + {x}^{2} = 64$

${x}^{2} = 14$

$x = \sqrt{14}$

$x = 3.7$
