Answer:
132p
Step-by-step explanation:
if 7 pens cost 84 total then you need to find the cost of each to know how much 11 pens would cost in total
84/7=12
now you know it's 12 each so just multiply 12 by 11 and you know how much for 11 total!
12*11=132p
Answer:
x = 12
, y = -3
Step-by-step explanation:
Solve the following system:
{2 x + 7 y = 3 | (equation 1)
x = -4 y | (equation 2)
Express the system in standard form:
{2 x + 7 y = 3 | (equation 1)
x + 4 y = 0 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + 7 y = 3 | (equation 1)
0 x+y/2 = -3/2 | (equation 2)
Multiply equation 2 by 2:
{2 x + 7 y = 3 | (equation 1)
0 x+y = -3 | (equation 2)
Subtract 7 × (equation 2) from equation 1:
{2 x+0 y = 24 | (equation 1)
0 x+y = -3 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 12 | (equation 1)
0 x+y = -3 | (equation 2)
Collect results:
Answer: {x = 12
, y = -3
Answer:
Each person runs 3 miles in a relay race.
Step-by-step explanation:
Given:
Distance of Relay race m = 12 miles.
The expression m divided by 4 is the distance each person runs in a relay race that is m miles.
Each person runs in relay race = 
Now given the total distance of the relay race is 12 miles.
i.e. value of m = 12 miles
Now substituting the value of m in above equation we get;
Each person runs in relay race = 
Hence each person runs 3 miles in a relay race.
