Answer:
x = -10 and y = 13
Step-by-step explanation:
let s solve the following
(1) -3x+2y=56
(2) -5x-2y=24
Let's do (1) + (2), it comes
-3x+2y-5x-2y=56+24=80
<=>
-8x=80
<=>
x = -80/8=-10
so x = -10 and from (1) we can write that
-3*(-10)+2y=56
<=>
2y = 56-30=26
<=>
y=26/2=13
so, y = 13
180/3=60
Each angle is 60 degrees.
Its 5y sorry if it’s wrong
Answer:
0.4655172413793
Step-by-step explanation:
45/87 ×-9/10 i
405÷870
0.4655172413793
Principal = 31250
Time= 2 and 1/2 years
Rate= 8% so first we take out the amount for 2 years which would be: 36450
Now we we will take out the amount for 1/2 years. Now the rate for 1/2 years is 4% with principal
The amount for 1/2 years for 4% rate is= 37908
Answer: 37908 is the amount after 2 and 1/2 years at the rate of 8%
