R - 17.1 = -4.8

denis-greek [22]

Answer: r=12.3 *The answer must have a positive sign or decimal point.*

Explanation:

First, you had to do is add 17.1 from both sides of an equation.

$r-17.1+17.1=-4.8+17.1$

And then, simplify by equation.

$17.1+-4.8=12.3$

You can also add by the numbers.

$12.3+4.8=17.1$

$r=12.3$

Hope this helps!

Please help with both questions

tresset_1 [31]

Value of n is greater than (-2) and less than or equal to 3.
n = {-1,0,1,2 3}

3x +5 > 16
Subtract 5 from both sides
3x > 16 - 5
3x > 11
x > 11/3
x> 3.67

X= 4 is the smallest value
