X=d-15. Duh.
think about it, its equal to the original price minus 15%
Answer:. 1/ 4(x+7)^4
Step-by-step explanation:we will get 4(x+7)^-4
So if we do the inverse , we will get
1 / 4(x+7)^4
42 ÷ 396
You could use 40 ÷ 400, which would give you 0.1 as an estimate.
You could also use 42 ÷ 420, which would also give you 0.1 as an estimate.
By the way, by a pair of "compatible numbers", it means when you can easily work out the sum by calculating the first digits multiplied or divided together, then add the zeros.
For example, with 40 ÷ 400, we know that
40 ÷ 40 is 1, so we just put the other 0 infront of the decimal point to make it 0.1.
If it was multiplying (2 x 600), you could work out 2 x 6 (12), then add the 0's to get 1,200
Answer:
x = 9
Step-by-step explanation:
All 3 sides of the triangle are congruent making it an equilateral triangle with all 3 angles being congruent.
Each angle is therefore 180° ÷ 3 = 60°
Hence
7x - 3 = 60 ( add 3 to both sides )
7x = 63 ( divide both sides by 7 )
x = 9
Answer:
hypotenuse
Step-by-step explanation:
When you use the distance formula you are calculating the length of the hypotenuse of a right triangle.
When using the distance formula, you are making a right triangle whose hypotenuse connects two given points.
