Your solution to your question would be 7a - 1967
Answer:
X=0
Y=4
Step-by-step explanation:
3x=12-3y
x=4-y
Plug 4-y in for x in the other equation:
2(4-y)+4y=16
8-2y+4y=16
2y=8
y=4
If x=4-y and y=4, x=4-4=0
12 geese left per hour. At 7:30 am there were 18 less geese than there were at 6:00 am. Since there was 1.5 hours between each time, and we know that 2/3 of 1.5 hours is 1 hour, we can solve using this equation:
2/3 * 18 = 12.
Answer: 67°.
Step-by-step explanation:
1) m∠PMR=m∠LMN=3x+19°;
2) m∠LMN+m∠LMP=180°, it can be written as 3x+19+9x-31=180;
3) if to solve the equation 3x+19+9x-31=180, then x=16;
4) m∠PMR=3x+19=48+19=67°.
In box one you have to distribute so -2(3x-5)= -6x-(-10)
