Solve the following system using elimination:
{7 x + 2 y = -19 | (equation 1)
{2 y - x = 21 | (equation 2)
Add 1/7 × (equation 1) to equation 2:
{7 x + 2 y = -19 | (equation 1)
{0 x+(16 y)/7 = 128/7 | (equation 2)
Multiply equation 2 by 7/16:
{7 x + 2 y = -19 | (equation 1)
{0 x+y = 8 | (equation 2)
Subtract 2 × (equation 2) from equation 1:
{7 x+0 y = -35 | (equation 1)
{0 x+y = 8 | (equation 2)
Divide equation 1 by 7:
{x+0 y = -5 | (equation 1)
{0 x+y = 8 | (equation 2)
Collect results:
Answer: {x = -5, y = 8
Answer 0.06*0.7+0.03=0.072 and 0.06*(-0.2)+0.03=0.018
here is the answer its in the picture and it also has the solution in picture 2
Answer:
D. diagonal = 20.10 cm
Step-by-step explanation:
Find the bottom diagonal using the length and width.
diagonal² = 8² + 12²
diagonal = √64+144
diagonal = √208
diagonal = 4√13
---------------------------------------------------------------------------------------------------------
Find diagonal of the rectangular solid:
diagonal² = (4√13)² + 14²
diagonal² = 208 + 196
diagonal = √404
diagonal = 20.10 cm
