Y=2x+6
gradient is found from the formula,
$\frac{ - 1}{ - \frac{1}{2} } = 2$

The sum of the two digits of a number is 16. The number formed by reversing the digits is 18 more than the original number. Dete

nydimaria [60]

9u-9t=18

original no. is 10t+u
reversed no. is 10u+t

so its (10u+t)-(10t+u)=18
which gives 9u-9t=18

–4.5t49.5t = 40 Please help

dlinn [17]

Answer:

t= -0.18

Step-by-step explanation:

Isolate t to get the unknown number:

(-4.5t)(49.5t) = 40

Multiply (-4.5t)(49.5t):

(-4.5t)(49.5t) = -222.75t

Now, write full equation:

-222.75t = 40

Isolate t by dividing -222.75 on both sides:

$\frac{-222.75}{-222.75}t=\frac{40}{-222.75}$

Cancel out left hand side:

$t=\frac{40}{-222.75}$

Simplify your answer:

$t=-0.17957351$

Approximate to 2 decimals:

$t=-0.18$

Evaluate 3 - (-1) + (-1) - 3.

lara [203]

Answer:

Step-by-step explanation:

3 - (-1) + (-1) -3 =

Minus and a negative makes it positive. In other words it would be written like this: 3 + 1 + (-1) - 3 =

Next step would be making it minus 1, because plus sign and negative makes the number to be subtracted. It would be rewritten like this: 3 + 1 - 1 - 3 =

Then you will simply add 3 and 1, which makes it 4. So it would be rewritten likes this: 4 - 1 - 3 =

Then you will simply subtract 1 from 4, which would equal to 3. So it would be rewritten like this: 3 - 3 =

Last step, would be subtracting 3 from 3. Whatever is subtracted from itself would always be 0.

So the answer would be 0!
