Answer:
There are two numbers 10 units from zero on the number line. These are 10 and -10.
Step-by-step explanation:
On a number line, if you move a pointer ten units right and left you will land on 10 and -10.
Answer:
x + 4
Step-by-step explanation:
whatever the number is goes into x and add that with 4 and you get your sum
EF = 15 cm.
Step-by-step explanation:
Step 1:
If the quadrilaterals, ABCD and EFGH are similar their side lengths will be of the same ratio throughout.
Comparing the quadrilaterals, we have AB and EF are similar, BC and FG are similar, CD and GH are similar, DA and HE are similar.
So the ratio of all these sides will be equal.
Step 2:

Of these lengths, we only have the values for AB, BC, CD, DA, GH, HE and need to determine the length of EF. By substituting the known values the ratio becomes;


So
cm. Which is the second option.

To better understand the problem see the attached figure
we have

Multiply by
both sides


Group terms that contain the same variable p and move the constant to the other side of the equation



Step-by-step explanation:
-35 x - 625 = 21875 so positive
263 x 0 = 0 so zero
-21 x 451 = - 9471 so negative
-350 x 89 = - 31150 so negative
