1/4 of x students made the honor roll in the first quarter
1/4 of x plus 18 equals 105
1/4 x + 18 = 105
1/4 x + 18 - 18 = 105 - 18
1/4 x = 87
Reciprocal to isolate variable
4/1(1/4 x) = 87(4/1)
x = 348
There is a total of 348 students in 7th grade
Answer: 19.8 Units
Step-by-step explanation:
The triangle is shown in the attached figure, and have three vertices: 
, 
and 
.
Each vertice represents a point in the cartesian plane and the length of each side of the triangle is the modulus of each vector.
In this sense, the modulus 
is calculated as shown:
Hence, for each vector:
Now, the perimeter of a triangle is the sum of its three sides:
Finally:
<span>10^log 23 = 23 .

Answer:
710
Step-by-step explanation:
7(1)3≈710 (after 1 is coming 3, and it's less than 5, so 1 remains the same, and 3 turns 0)
Your end goal is to have $6000 total in 12 months. since you have $2400 already you can subtract that from 6000 leaving you with $3600 over the course of 12 months. since you already put $150 in a month over the course of 12 months you would have $1800 which is only half of the goal of $3600. in order for you to put in $3600 you would have to put an additional 150 in your savings along with your regular 150 making the answer b.
