The ratio of low-top to the total number of shoes is 4:15
Answer:
6- yes
9- yes
3- no
7- yes
Step-by-step explanation:
Greater than or equal to answers will work!
6*3= 18 which is equal to 18
9*3= 27 which is greater than 18
3*3=9 which is less than 18
7*3=21 which is greater than 18
The correct answer is x = -90.
To find this, solve using the order of operations. See the example below.
x/-3 - 41 = -11 ----> Add 41 to both sides
x/-3 = 30 ----> Multiply each side by -3
x = -90
A ratio can be written in three different ways: 3 to 4, 3:4, and 3/4
What does this mean? It means that for every group of 7 students (3+4) there are 3 boys and 4 girls. And how many groups do we have? We have:
245/7= 35 We have 35 groups, and we just said that each group has 3 boys and 4 girls:
35*3= 105 boys
35*4= 140 girls
