When u=-2, put that in where you see "u". use parentheses.
-4(-2)+4x=12
-4*-2=8 ➡positive 8 since a negative times a negative is always positive

now look for x
8+4x=12
subtract 8 from both sides. get x by itself.
-8+8+4x=12-8
4x=4➡ divide both sides by 4. a number divided by itself is 1 (unless one side is negative, then the answer is negative)
4/4=1

x=1
The number of people increased by 2.
This means as a ratio it is now 6/4 as many as originally planned.
6/4 can be reduced to 3/2.
The time and the number of people are inversely proportional, so the food would last 2/3 ( inverse is flipping the original ratio over) the original length of time.
This means the length of time the food lasts is reduced by 1/3, which is 33.3%
It’s times by 5 just graph the points on the graph then count how much the rise and run is and then you have your slop
Answer:
4250
Step-by-step explanation:
5000 packs of gum were produced by the factory.
85% of them contained mint-flavoured gum.
That is,
(85/ 100) × 5000 packs contained mint-flavoured gum.
= 85 × 50
= 4250.
Answer:
Out of 5000 packs, 4250 contained mint-flavored gum.
Answer:B. Her mean, median and mode are equal.
Step-by-step explanation:
Mean = (sum of the outcomes)/(total number of outcomes)
Total number of rounds played is 7
The scores for the 7 rounds played are - 6, - 4, - 1 , +3 , - 2, -1, +4
Sum of the scores = - 6 - 4 - 1 + 3 - 2 -1 + 4 = -7
Mean = - 7/7 = - 1
The mode is the most occurring score. Looking at the scores, - 1 occurred twice, so the mode is - 1
The median is the middle score. We would determine it by rearranging the scores in increasing or decreasing order. It becomes
- 6, - 4, - 2, -1, -1, +3, +4
The median is -1
The true statement is
B. Her mean, median and mode are equal.
