Which of the following is the radical expression of 2 times d to the seven tenths power? Your root index 7 of 2 d to the power of 10 end root root index 10 of 2 d to the power of 7 end root 2root index 10 of d to the power of 7 end root 2root index 7 of d to the power of 10 end root

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

the answer is 8/21

hope this
