Step-by-step explanation:
Answer: first sawmill charges more for each meter of wood. And first mill has a cheaper price for 5-meter wooden beam.
Step-by-step explanation:
P=5+20x. The first sawmill charges $20. Then 110-20/5-0=18 Which means The second sawmill charges $18 for each meter of wood. Since 20>18 The first sawmill charges more for each meter of wood.
P = 5+20x
=5+20x•5
= 105
The first mill charges $105 For a 5 meter beam while the second beam charges $110
8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
Answer:
Solution for 252 is what percent of 350:
252:350*100 =
(252*100):350 =
25200:350 = 72
Step-by-step explanation:
pls Mark my answer in brainlist and follow me
(20*16 ft^2)(144 in^2/ft^2)(tiles/(10*10 in^2)
320ft^2(144in^2/ft^2)(tiles/100in^2)=460.8 tiles
However tiles are quantized integer units so 461 tiles will be needed to tile the kitchen.
