Answer:
70
Step-by-step explanation:
69.65
We look at the tenths place to determine if we round up or leave it alone
.6 is greater then or equal to five so we need to round the 9 up
69.65 rounds to 70
(4.77/100)*35
(4.77*35)/100
166.95/100= 1.6695
=1.67
The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 +
37
- t + 37 ≤ 3
t ≤
40
- t ≤ 3 - 37
- t ≤ - 34 / *( - 1 )
t ≥ 34

Answer:
x=12
Step-by-step explanation:
5(x-3)=45
x=12
Y=-X-3
X+Y=4
You'll want to get X or Y by itself, which in this question it already is.
After that, use substitution (Plug -X-3 in place of Y in X+Y=4)
Equation should look like X+(-X-3)=4
Solve that equation
X+(-X-3)=4
X+(-X) cancels eachother out, leaving you with (-3)=4
Add 3 to both sides of (-3)=4, leaving you with 0=7
0 Can't equal 7, so this equation has no solutions
