Answer:
24 = no. of dozens of donuts
60 = no. of dozens of cookies
Step-by-step explanation:
The ratio of no. of dozens of donuts to no. of dozens of cookies is 2 to 5
Let 2x = no. of dozens of donuts
and 5x = no. of dozens of cookies
Then 2x + 5x = 84
7x = 84
x = 12
So, 2x = 2(12) = 24 = no. of dozens of donuts
and 5x = 5(12) = 60 = no. of dozens of cookies
Check: 24/60 = 2/5 and 24 + 60 = 84
Answer:
y = -4
Step-by-step explanation:
Solve the following system:
{4 x + 5 y = -12 | (equation 1)
3 y - 2 x = -16 | (equation 2)
Add 1/2 × (equation 1) to equation 2:
{4 x + 5 y = -12 | (equation 1)
0 x+(11 y)/2 = -22 | (equation 2)
Multiply equation 2 by 2/11:
{4 x + 5 y = -12 | (equation 1)
0 x+y = -4 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{4 x+0 y = 8 | (equation 1)
0 x+y = -4 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 2 | (equation 1)
0 x+y = -4 | (equation 2)
Collect results:
Answer: {x = 2
, y = -4
