On Tuesday, Jaheim and three of his friends ate dinner at a restaurant where meals cost $12 per person, but are 25% off every Tuesday. The tax on their meal was 8%, and they left a tip that was 20% of the pre-tax price. Write an expression that can be used to find the cost of one persons meal, not including tax or tip. How much did they all 4 of them spend in all?

8

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).

probably the last option

step-by-step explanation:

"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
