Answer: i think the answer is 1
Step-by-step explanation:
A model being 0.001 shaded would be 0.1% or 1/1000 of the whole model. 1 would equal the whole model being shaded, but that’s not the case. Instead, it’s in the thousandths, so that’s 1/1000 or 0.1% of the whole model shaded.
Answer: These lines are parallel
Step-by-step explanation: There are two equations. y=4x+6, and the second one equals y=4x-3. Because they have the same slope, they are parallel.
Answer:
27, 20
Step-by-step explanation:
x + y = 47
x - y = 7
if we solve the second equation for 'x' we can:
let 'x' = y+7
substitute that expression for 'x' in the first equation to get:
y+7 + y = 47
2y = 40
y = 20
now find 'x':
x - 20 = 7
x = 27
