Step-by-step explanation:
I did it in school city 2021 and Im in Honors Math please make me brainliest
-0.15 = -15/100 = -3/20
-7.75 = -7 3/4
-12.54 = -12 54/100 = -12 27/50
2r² + 3s³ - r² + 4t² - r² = 3s³ + 4t²
<span>if s = -3 and t = 5
</span>3s³ + 4t² = 3 * (-3)³ + 4 * 5² = 3 * (-27) + 4 * 25 = -81 + 100 = 19
Answer: 19
Y=x+5
Let's say we are given that x is equal to 5.
Thus, since x=5, we can <em>replace</em> x with the number 5.
So instead of y=x+5, we now have:
y=5+5=
Another example:
x=4+y
where y= 2
x=4+2
