1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23
= 15+8=23
23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23
= 0+8 is not 23
thus, (0,4) is not solution for 5x + 2y = 23
Jacob used 1/7 of a liter
of water.
He needs to fill 1/9 of the fish aquarium.
Find how many liters would Jacob need to fill the aquarium
=> Let x = liters of water need to fill the aquarium
=> x/1 = 1/7 divided by 1/9
=> x = 1/7 x 9/1
=> x = 9/7, since this is an improper fraction, let’s convert it to
mixed fraction
=> x = 1 and 2/7
So, Jacob need 1 and 2/7 liter of water to fill the whole aquarium.
Answer:
GCF = 20
Step-by-step explanation:
he answer would be 20 so then you would get (3-2y) as a final answer
(0,5)(-10,0)
slope = (0 - 5) / (-10 - 0) = -5/-10 = 1/2
y = mx + b
slope(m) = 1/2
use either of ur points (0,5)...x = 0 and y = 5
now we sub and find b, the y int
5 = 1/2(0) + b
5 = b
so ur equation is : y = 1/2x + 5
Area of sector = (1/2) * r^2 * α where α = the angle in radians
= 1/2 * 12^2 * π/3
= 72 π / 3 = 24 π Answer
