Answer:
Step-by-step explanation:
we know that
-----> by complementary angles
solve for x
B there is inf. many solutions:
2x-4y=8 is y = 1/2x - 2
8x-16y=32 is y = 1/2x - 2
Answer: 2/3x+4=-18
Step-by-step explanation:
2/3(x+6)=-18
do distributive property
2/3*x=2/3x
2/3*6=4
so you get
2/3x+4=-18
Answer:
Hardwood = 56 bags,
Bag and Pine = 100 bags
Step-by-step explanation:
let number of bags of hardwood be x and for pine be y
4.25x+3.75y=613----equation1
x+y=156 ---equation2
rewrite equation2 as y=156-x
substitute to equation1 = 4.25x+3.75(156-x)=613
simplify to get x = 56
from equation 2, y=156-x
y=156-56 = 100
Therefore
Hardwood = 56 bags,
Bag and Pine = 100 bags
