I’m doing this to in 8th grade I don’t understand it neither
We have to calculate the total cost of the meal. We know that Adam ( A ) and his dad ( D ) share the cost of the meal in the ratio 2 : 3 and that Adam`s dad pays 52.20 Pounds. So A : D = 2 : 3; A : 52.20 = 2 : 3. Using the cross products, A * 3 = 2 * 52.20; A * 3 = 104.40; A = 104.40 : 3; A = 34.80 Pounds. Finally, A + D = 34.80 + 52.20 = 87.00. Answer: The total cost of the meal is 87 Pounds<span>. </span>
Answer:
sorry cant see the question
Step-by-step explanation:
Ans given below
42-6=-2d
36=-2d
d=-18
8 to 6 is a common differnce is -2
6 to 4 is a common diference of -2
4 to 2 is a common diference of -2
common diffference is -2
an=8-2(n-1) would be the explicit formula
