Answer:
if it's finding x
#1 x<-1
#2 x<4
Step-by-step explanation:
#1
2x-16<-18
add 16 to both sides
2x<-2
then divide 2 to both sides
x<-1
#2
2x-16+4x<8
add like terms
6x-16+<8
add sixteen to both sides
6x<24
divide six to both sides
x<4
Answer:
About 630 seventh-grade students would like to snorkel
Step-by-step explanation:
if you do
7/9 x 90 equals 630/810 total students
The answer is 4/7. see it from the multiple of 3...3*4 =12 and 3*7= 21. So this is the answer: 4/7.
The sum of the interior angles of a hexagon is 720 degrees. If 3 angles are congruent, each with measure x degrees, and the other 3 angles are also congruent to each other, each with measure 2x degrees, then the total sum of all 6 angles would be 3x + 3(2x) = 9x. If this is equal to 720, then x = 80 degrees, while 2x = 160 degrees.
Therefore, there are 3 80-degree angles and 3 160-degree angles.
The answer is 3/8. Christopher with have to share 3/8 of pie with each of his friends.
