pls help guys ily 💕
1. To determine which of the given options could be represented by -8, we need to understand what -8 means in each context.
a. a drop of 8 meters: This option does not represent -8 because a negative sign represents a descent or decrease. So, -8 meters would indicate a drop of 8 meters.
b. 8 t-shirts: This option does not represent -8 because -8 represents a negative quantity, while 8 t-shirts denotes a positive quantity.
c. sea levels in 8 places of the world: This option does not represent -8 because -8 represents a negative quantity, while sea levels in different places could be either positive or negative.
d. 8°C above zero: This option does not represent -8 because a positive value represents 8°C above zero, while -8 denotes 8 degrees below zero.
Therefore, none of the given options could be represented by -8.
2. To compare the expressions 5+(-4) and -14+(-7), we need to calculate their values and compare them.
5 + (-4) = 1
-14 + (-7) = -21
Comparing 1 and -21, we see that 1 is greater than -21.
Therefore, the answer is c. >
3. To order the integers 6, 11, 16, -8, and -5 from least to greatest, we simply arrange them in ascending order.
Arranging the integers in ascending order: -8, -5, 6, 11, 16
Therefore, the answer is b. -8, -5, 6, 11, 16
4. To find the sum of -8 and -2, we add them together.
-8 + (-2) = -10
Therefore, the answer is a. -10
To find the difference between -8 and -7, we subtract -7 from -8.
-8 - (-7) = -8 + 7 = -1
Therefore, the answer is d. -1
To solve the equation m + 45 = 32, we need to isolate the variable m.
Subtracting 45 from both sides:
m + 45 - 45 = 32 - 45
m = -13
Therefore, the answer is b. -13
To solve the equation -13v = 195, we need to isolate the variable v.
Dividing both sides by -13:
(-13v)/(-13) = 195/(-13)
v = -15
Therefore, the answer is d. -15
Solving equations means getting the letter on one side and the numbers on the other side. You have to use "opposite" operations to do this.
Say the question was x + 3 = 5
we need to get the 3 to the other side, the opposite of adding 3 is subtracting 3 so we apply it to both sides
x + 3 - 3 = 5 - 3
x = 2
The order to undo the equation and get x alone is BEDMAS backwards or... do the things that are added or subtracted first (those things on the same side as the variable.... but NOT connected to it... like the +3 in x +3), then you work on what is connected to x.
If it is 3x then you would have to divide both sides by 3 to get the x alone.
If it was x/7 then you would have to do the opposite of dividing by 7, so times both sides by 7 to get the x alone.
Hope this helps : )
what, no ideas on any of these?
We've done this already, and don't need the practice.
If you have studied the material, you surely cannot be totally clueless ...
