The answer is C. 5:1 . 15/3 = 5/1 and 25/5 = 5/1
Answer:
x = 5
, y = 3
Step-by-step explanation:
Solve the following system:
{3 x + 4 y = 27 | (equation 1)
5 x - 3 y = 16 | (equation 2)
Swap equation 1 with equation 2:
{5 x - 3 y = 16 | (equation 1)
3 x + 4 y = 27 | (equation 2)
Subtract 3/5 × (equation 1) from equation 2:
{5 x - 3 y = 16 | (equation 1)
0 x+(29 y)/5 = 87/5 | (equation 2)
Multiply equation 2 by 5/29:
{5 x - 3 y = 16 | (equation 1)
0 x+y = 3 | (equation 2)
Add 3 × (equation 2) to equation 1:
{5 x+0 y = 25 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 5 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = 5
, y = 3
Graph A is the correct answer tell me if you need a step by step explanation
Answer:
this is the formula for a volume of a sphere
4
/3*π*r^3 so plug in the radius
4/3*3.14*3^3=
4/3=1.33333333
1.333*3.14=4.186666562
4.186666562*3^3=113
the volume of the sphere is 113
Step-by-step explanation:
A pentagon gas 5 sides. Therefore multiply the length of one side by 5.
921x5=4605 feet
