please help ill give brainliest plz give me a simple answer
Answers
Answer:
Bottom answer
Step-by-step explanation:
This says the absolute value of a number is greater than 3.
First, any positive number greater than 3 will work.
But since they also say the absolute value, any negative lower than -3 will also work. For example, the absolute value of -4 is 4 which is greater than 3.
However, it cannot be 3 or -3 since it must be greater than 3. If you notice the bottom answer has an OPEN circle on 3 and -3 which means those two numbers are not included in the answer. It is anything greater than 3 and anything less than -3 but not including those two numbers.
Answer:
4th option
Step-by-step explanation:
d | > 3
The solution is going to be all the points that are more than 3 units away from zero , but not equal to zero
- 4 and 4 are more than 3 units away from zero
The required graph is one with an open circle at - 3 and 3 with

Answers
Answer:
32 lbs
Step-by-step explanation:
Given:
1/4 spicy trail mix
3/8 regular trail mix
20 total mix
Math:
1/4 + 3/8 = 5/8
20/ (5/8) = 32
Answer:
32 pounds
Step-by-step explanation:
Fraction of supply for regular trail mix= ⅜
Fraction of supply for spicy trial mix
= ¼
[tex] = \frac{2}{8} [/tex]
We multiply both the denominator and numerator by 2 for the fraction of supply used for spicy trail mix so that both fractions have a common denominator of 8. This is because the amount of raisins he has in his supply is constant.
Simplifying the above information into units form:
Total (supply)= 8 units
Regular trail mix= 3 units
Spicy trail mix= 2 units
Raisins used this week
= (3 +2) units
= 5 units
Since he used 20 pounds of raisins this week, we can equate 5 units to 20 pounds.
5 units ----- 20 pounds
Divide both sides by 5 to find how much raisins 1 unit represents:
1 unit ----- 20 ÷5= 4 pounds
Since his supply was 8 units of raisins,
8 units ----- 4(8)= 32 pounds
∴ He had 32 pounds of raisins at the beginning of the week.

0.297 x 7.1 = 297 + 20790 / 21.087 is it true or false
Answers
Hey there!
0.297 * 7.1 = 297 + 20,790/21.087
Well….
0.297 * 7.1
= 2.1087
297 + 20,790/21.087
= 2.97 + 985.915493
= 1282.915493
2.1087 ≠ 1282.915493
Thus, your answer is false

A regular pentagon, a regular octagon, and∠ meet at a point. What is m< SBY?
Answers
Answer:
117
Step-by-step explanation:
Each angle of a regular pentagon = 108
Each angle of regular octagon = 135
135+ 108 + ∠SBY = 360
243 + ∠SBY = 360
∠SBY = 360 - 243
∠SBY = 117°

X+2x-5+6= 0 How would you picture model this to solve for x?
Answers
Hey there!
x + 2x - 5 + 6 = 0
1x + 2x - 5 + 6 = 0
3x + 1 = 0
SUBTRACT 1 to BOTH SIDES
3x + 1 - 1 = 0 - 1
CANCEL out: 1 - 1 because that gives you 0
KEEP: 0 - 1 because that helps solve for the x-value
0 - 1 = -1
NEW EQUATION: 3x = -1
DIVIDE 3 to BOTH SIDES
3x/3 = -1/3
CANCEL out: 3/3 because that gives you 1
KEEP: -1/3 because it gives you the value of x
SIMPLIFY IT
x = -1/3
Therefore, your answer is: x = - 1/3
