In an orchestra there are 4 violas for every 7 violins. If there are 12 more violins than violas, how many of each instrument are there? use the tape diagram method

0.32

step-by-step explanation:

2.24/7

"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

this cant be answered without the graph. you may need to add it.
