Cross multiply.
5.4x=9*25.8
5.4x=232.2 Divide both sides by 5.4
x=43
Answer: The tip left for the servers was $14.80
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Total cost of the food (before tax) = $82.25
</em>
- <em>Tip = 18% of the amount before the tax
</em>
So, to calculate the tip we have to multiply the cost of the food before tax ($82.25) by the 0.18 (percentage in decimal form, 18/100= 0.18).
Mathematically speaking:
82.25 x 0.18 = $14.80
The tip left for the servers was $14.80
Answer:
Sum of volumes = (16.6 ± 0.03) cm³
Difference of volumes = (3.8 ± 0.03) cm³
Step-by-step explanation:
Solution
V₁ = (10.2 ± 0.02) cm³ and V₂ = (6.4 ± 0.01) cm³.
∆V = ± (∆V₁ + ∆V₂)
= ± (0.02 + 0.01) cm³
= ± 0.03 cm³
V₁ + V₂ = (10.2 + 6.4) cm³ = 16.6 cm³ and
V₁ - V₂ = (10.2 - 6.4) cm³ = 3.8 cm³
Hence, sum of volumes = (16.6 ± 0.03) cm³
and difference of volumes = (3.8 ± 0.03) cm³

8x + 2 > 34
Subtract 2 from both sides to start isolating x
8x > 32
Divide both sides by 8 to isolate x
x > 4
x is greater than 4
