The supermarket is engaged in a sales promotion. You can get one free when you buy four soaps. How much is the discount?
Please help me with my homework,
20% off. Actually, I bought five soaps and only spent four soaps. 4 / 5 = 80%. I hope it can help you
If the function FX = a to the power of X (0 < a < 1), the maximum value of X ∈ [1,2] is two times larger than the minimum value, then a is equal to
The distance between a and B is 420 kilometers. Two cars drive from a to B at the same time. The first car travels 42 kilometers per hour, and the second car 28 kilometers per hour. The first car returns to B immediately. How many hours do the two cars share from departure to meeting? I will adopt the map!
Encounter = 420 × 2 ÷ (42 + 28) = 12 hours
1 / 2 χ minus 1 / 3 χ and so on and 5 / 6 (solving equation)
Multiply both sides of the equation by 6 to get 3x-2x = 5
The result of merging the similar items is: x = 5
So the solution of the original equation is x = 5
Train a is going from a to B at a speed of 150 km / h. one hour later, train B is going from B to a at a speed of 70 km / h. If a and B are 200 km apart, how far is the meeting point from a?
Time required for meeting: (200-150) / (150 + 70) = 5 / 22 (H)
Distance between two vehicles meeting point and ground a: 150 + 150 x 5 / 22 = 184 and 1 / 11 (km)
Solving the equation 81 ^ 2x △ 9 ^ 2x △ 3 ^ x = 81 about X
81^2x÷9^2x÷3^x=81
3^8x÷3^4x÷3^x=81
3^(8x-4x-x)=3^4
8x-4x-x=4
x=4/3
