Soo... The ratio of blue to green is 4:3 right?
and there are 21 balloons!
4 + 3 is 7! So we divide 21 by 7 and get 3!

Answer:
Multiplying a function by a constant expands the graph vertically by the magnitude of the constant. (If the constant is negative, the graph is also reflected about the x-axis.)
Step-by-step explanation:
Each value of a·ln(x) will be a factor of "a" farther away from the x-axis than it is for the parent function ln(x). That is, a·ln(x) is a vertically expanded version of the parent function ln(x). When |a| > 1, the expansion increases the distance from the x-axis.
180=(9X-11)+(4X+1)+(7X-3)
180=20x-13
193=20x
9.65=x
"3 miles below sea level" may be written as -3. The negative indicates you are below sea level. Going above sea level means the value would be positive.
"earning 45 dollars" can be written as +45 or simply 45. If you lost 45 dollars, then it would be -45. If you are in debt 45 dollars, then it would be -45.
"moving back 5 spaces" is represented by -5 whereas moving forward 5 spaces is +5 or simply 5.
