Answer:
Step-by-step explanation:
Are you certain you wrote the question accurately?—because none of the choices is correct.
rearrange 3x+y =-5 to solve for y:
y = -3x-5
substitute -3x-5 for y into the second equation:
12x + 3y = 13
12x + 3(-3x-5) = 13
12x - 9x - 15 = 13
3x = 28
x = 28/3
y = -3x-5 = -33
solution: (28/3, -33)
Answer:
5:4
Step-by-step explanation:
There are 12 inches in one foot, so there are 24 inches in 2 feet.
Therefore, the ratio that compares 30 inches to 2 feet is the ratio that compares 30 inches to 24 inches.
This is

Answer:
The length of the model is 6 inches.
Step-by-step explanation:
The wingspan of the airplane and length of the airplane are a ratio of 4:3
The model is also supposed to be 4:3.
4:3 x 2 = 8:6
Or, 20x12=240
240/8=30
15x12=180
180/30=6.
Answer:
Future Value= $5,886.13
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,425
Number of periods (n)= 1 year
Interest rate (i)= 8.5% = 0.085
<u>To calculate the future value after one year, we need to use the following formula:</u>
<u></u>
FV= PV*(1+i)^n
FV= 5,425*(1.085^1)
FV= $5,886.13
Answer:
