One-forth of r can be written as,
r/4.
Now, r/4 is subtracted from 10 and this is greater than 5.
Therefore, inequality is,
10 - r/4 > 5
Answer:
4/5
Step-by-step explanation:
because the ratio is 4:5
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
A system is:
1.25 x + 2.25 y = 16
x + y = 8
---------------------------
y = 8 - x
1.25 x + 2.25 * ( 8 - x ) = 16
1.25 x + 18 - 2.25 x = 16
- x = 16 - 18
- x = - 2
x = 2
y = 8 - 2
y = 6
