48 students were divided into 2 groups for a field trip. The first group was 3 times as large as the second group less 12. How many students were in each group?

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

1. 34

2. 268

3. x=14.4

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
