Answer:
x = -1
, y = 5
Step-by-step explanation:
Solve the following system:
{5 x + 3 y = 10 | (equation 1)
x = y - 6 | (equation 2)
Express the system in standard form:
{5 x + 3 y = 10 | (equation 1)
x - y = -6 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 3 y = 10 | (equation 1)
0 x - (8 y)/5 = -8 | (equation 2)
Multiply equation 2 by -5/8:
{5 x + 3 y = 10 | (equation 1)
0 x+y = 5 | (equation 2)
Subtract 3 × (equation 2) from equation 1:
{5 x+0 y = -5 | (equation 1)
0 x+y = 5 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -1 | (equation 1)
0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -1
, y = 5
Step-by-step explanation: Victor jumps farther than Meg.
If Victor jumps 9 feet and 2 inches and Meg jumps 7 feet and 4 inches, that means that Victor jumps 1 foot 10 inches farther than Meg.
Lets learn our conversations: 1 foot = 12 inches
If Victor jumps 9 feet, that means that 9 feet = 108 inches + 2 inches, which equals 110 total inches jumped.
If Meg jumps 7 feet, that means that 7 feet = 84 inches + 4 inches, which equals 88 total inches jumped.
110 - 88 = 22 inches.
So, Victor jumped 22 inches farther than Meg, or 1 foot and 10 inches farther than Meg.

Answer:
The area of the space is( 0.1155 m^2)
Answer:
1 = 35
2 = 55
Step-by-step explanation:
so we know that between 1 and 2 it is 90 degrees we also know that angle 1 and the angel to the left of it make 180 degrees so do
180 - 90 = 90
this means the angle next to line 1 is also 90 degrees
then we would see that the 55 degrees the 90 degrees and angle 1 make 180 degrees so do
55 + 90 = 145
180 - 145 = 35 degrees so angle 1 is 35 degrees
then we would find angle 2
90 - 35 = 55 degrees so angle 2 = 55
hope this helps : )
