Answer:
Step-by-step explanation:
Let the monthly rent be x.
<u>Then we have:</u>
- x + 0.5x + 0.4x = 3800
- 1.9x = 3800
- x = 3800/1.9
- x = 2000
Monthly rent is $2000
Answer:
Is it too late to answer this?
Step-by-step explanation:
Here's my step-by-step explanation:
We're just gonna factor.
If your teacher has spoken of FOIL, then he/she has probably said that it means First Outer Inner Last and that it helps with distributing problems like these.
Right, so let's get to it.
Can you see the FOIL method being spread out here? Let's keep going.
Hope this helps, and let me know if I made a mistake! ^_^
Hey there!
We can see we are subtracting 2 every time, and we have 95 terms left fo figure out, so we multiply 95 by 2 and get 190, then subtract that from 15.
15 - 190 = -175, therefore, that's the the 100th term.
Have a terrifcly amazing day!
Answer:
x=-4
y=1
Step-by-step explanation:
For the given system of equations,
2.5x-3y=-13.....eqn(1)
3.25x-y=-14.....eqn(2)
We first make y the subject of eqn (2)
This implies that,
y=3.25x+14.....eqn(3)
We substitute eqn (3) into eqn (1)
2.5x-3(3.25x+14)=-13
2.5x-9.75x-42=-13
-42+13=9.75x-2.5x
-29=7.25x
Dividing through by 7.25, we obtain
x=-4
We now put the value of x into eqn (2)
3.25(-4)-y=-14
This implies that,
-13+14=y
y=1
