Answer:
-13
Step-by-step explanation:
Opposite of 9t = -9t
Taking the sum of 9t - 13 and -9t
Sum = 9t - 13 + (-9t)
Sum = 9t - 13 - 9t
Sum = 9t-9t - 13
Sum = -13
Hence the expression in standard form is -13
Answer:
3

2
Explanation:
First put change the words into an equation:
√
3
×
√
6
Now you can multiply them together as you would normally multiply:
√
3
×
√
6
=
√
18
Now let's prime factor 18 and see if there are any squares that we can take out of it to simplify. All we have to see is if there are 2 numbers that are the same:
18
/ \
6
3
/ \
2
3
As you can see, we have a square:
3
×
3
=
9
So take
√
9
out of
√
18
. You should have:
√
9
√
2
But since
√
9
=
3
we can simplify further to make:
√
9
√
2
→
3
√
2

z = 1.25
Step-by-step explanation:
Answer:
The two numbers marked on the number line are -5 and 7.
Two inequalities to compare the marked numbers on the number line:
-5 < 7 or 7 > -5
The <u><em>written form</em></u> of the two inequalities are:
-5 < 7 : Negative five is <u>less than</u> positive seven.
7 > -5 : Positive seven is <u>greater than</u> negative five.
