Answer:
Step-by-step explanation:
The line given has a slope of 7.5 and a point at (12, 80)
Because of the slope, simply subtract 2 from the x and subtract 15 from the y to get another point, at (10, 65)
Thus, simply put your points at (10, 65) and (12, 80)
Hope it helps and let me know if you want me to elaborate.
Answer:
The two locker numbers are 68 & 69.
Step-by-step explanation:
Let one locker number be x then other will be , then other will be x+1.
We are given that sum is 137.
x+x+1=137
2x+1=137
2x=136
x = 68
The two locker numbers are 68 & 69.
The distributive property is a(b+c) = ab + ac or a(b-c) = ab - ac
So here are some potential answers:
8(50 + 4) = 8·50 + 8·4
8(60 - 6) = 8·60 - 8·6
I prefer the first answer
Answer:
so the answer will be 1
Step-by-step explanation:
An oil tanker can be emptied by the main pump in 5 hours.
An auxilary pump can empty the tanker in 14 hours.
If the main pump is started at 7pm, when should the auxilary pump be started
so that the tanker is emptied by 11pm?
:
Let t = no. of hrs to run the Aux pump
:
The main pump will run 4 hr (7 - 11 pm)
:
Let the completed job = 1; (an empty Tanker)
:
The shared work equation
4%2F5 + t%2F14 = 1
Multiply equation by 70 to get rid of the equation, results:
14(4) + 5t = 70
56 + 5t = 70
5t = 70 - 56
5t = 14
t = 14%2F5
t = 2.8 hrs to run the aux pump
:
2.8 hr = 2 + .8(60) = 2 hrs 48 min
:
Subtract 2:48 from 11:00 = 8:12 PM start the aux pump
;
;
Check solution
4/5 + 2.8/14 =
.8 + .2 = 1
Answer:
x= -1 and 1
Step-by-step explanation:
look at where y=0 and what x value intersects it
