Answer:
14/33
Step-by-step explanation:
The total amount of beads is 8+4 = 12. 8 of these are black beads, so that is what we want, so 8/12 or 2/3. For the second one, one black bead is already taken so 8-1 = 7 are left and for the total 12 - 1 = 11 are left, so 7/11. Multiply this by 2/3 and we get 14/33.
In linear equation, 15.2% did the total number of students on the honor roll decrease.
What in mathematics is a linear equation?
- A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
- Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
50 × 24% = 12
50 × 14%= 7
12+ 7 = 19
50+75 = 125
19 ÷125= 15.2%
