Answer:
use this equation: 150=1x+0.5y
Step-by-step explanation:
a) standard form equation above
b) 150=1x+0.5y
subtract 1x from both sides
then divide all by 0.5 to get slope intercept form
c) plug it in: 150=1(40)+0.5y and solve to get 220
d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)
Answer:
12 weeks.
Step-by-step explanation:
Keiths dog will need to lose 15 pounds to get down to 75 pounds. If he loses 1.25 pounds per week, it will take 12 weeks to get down to 75 pounds. To figure this out, you would use the equation:
90 - 75 = 15
15 / 1.25 = 12
That is how you would get 12 weeks.
Answer:
AB = 28 inches
Step-by-step explanation:
The length of LB = 14 inches
But; LB = AL
Therefore; AL = 14 inches
But; AB = AL + LB
Thus; AB = 14 inches + 14 inches
= 28 inches
Answer:
the density of copper is 90.03g/cm³
Step-by-step explanation:
This problem bothers on the density of a substance, this case for a copper material
Given data
Mass of copper m = 1355g
Volume of copper block v= l*b*h
10*5*3=150cm³
We know that the density
ρ= mass/volume
ρ= 1355/150
ρ= 90.03g/cm²
The density of a substance is defined as the mass of the substance per unit volume
Step-by-step explanation:
Answer C)
Explanation:
MN + NP = MP
MP = 39
Therefore, 4(x + 5) + 2x + 1= MP
So, 4(x + 5) + 2x + 1= 39
(4x + 20) + 2x +1 = 39
So, (4x + 2x) + (20 + 1) = 39
6x + 21 = 39
Addition changes to Subtraction
So, 6x = 39 - 21
6x = 18
Multiplication changes to Division
x= 18/6
x=3
Therefore MN = 4(x + 5)
So, 4(3 + 5) = 4(8)
4(8) = 32
Therefore, MN = 32
Hope this helps!
