I would need to see the drop downs.
At every pi/2 that doesn't result in a whole number value of pi. so 3pi/2, 5pi/2, etc..
0.5 - 0.03 = 0.47
2 tenths= 0.2
5 tenths and 3 hundredths are not similar units so you can't simply subtract 5 and 3. The correct answer is 0.47.
Answer:
x=-22
Step-by-step explanation:
1/2(x+18)=4(2x-6)-9x
Distribute the 4
1/2(x+18)=4(2x)-4(6)-9x
1/2(x+18)=8x-24-9x
Combine like terms
1/2(x+18)=-x-24
Multiply each side by 2
2*1/2(x+18)=2(-x-24)
Distribute
x+18 = -2x-48
Add 2x to each side
x+2x+18 = -2x+2x-48
3x+18 = -48
Subtract 18 from each side
3x+18-18 = -48-18
3x = -66
Divide by 3
3x/3 = -66/3
x = -22
Answer:
Step-by-step explanation:
The given equations are:
-9.5x – 2.5y = –4.3 (1)
and 7x + 2.5y = 0.8 (2)
Adding equation (1) and (2) together, we get
-9.5x-2.5y+7x+2.5y=-4.3+0.8
⇒-2.5x=-3.5
⇒x=1.4
Now, substitute the value of x=1.4 in equation (1),
-9.5(1.4)-2.5y=-4.3
⇒-13.3-2.5y=-4.3
⇒-13.3+4.3=2.5y
⇒-9=2.5y
⇒y=-3.6
Thus, the value of x and y are 1.4 and -3.6 respectively.
