Hey there, Lets solve this step by step.
<span>A number t divided by 82
</span>
Let the number be represented by y.
<span>t divided by 82 = t / 8
</span>
Therefore-
<span>In algebraic expressions, "y" is normally used as the dependent variable and "x" is normally used as the independent variable, instead of other variables. So that is why i used the variable y in the equation. </span>

Answer:
whatever is higher than 1.5 is higher than r
Step-by-step explanation:
-1.2 ≤ -0.8r
-1.2/0.8 ≤ -0.8r/0.8
-1.5 ≤ -r
-1.5/-1 ≤ -r/-1
1.5 ≥ r
1.5 is equal to or bigger than r
Answer:
19
Step-by-step explanation:
1. y= -5x + 12
y= -5x – 7
2. -5x + 12
-(-5x – 7)
3. -5x + 12
<u>5x + 7</u>
0 +19
4. 19
