Blanca earns a yearly salary of $55,000. Isabel earns a yearly salary of $63,000. Blanca will receive a salary increase of $3,700 per year, and Isabel will receive a salary increase of $2,900 per year. Which equation can be used to find n, the number of years it will take Blanca to earn the same salary as Isabel? 55,000n + 3,700n = 63,000n + 2,900n 55,000n + 3,700 = 63,000 + 2,900n 55,000n + 3,700n = 63,000n + 2,900 55,000 + 3,700n = 63,000 + 2,900n

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

step-by-step explanation:

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

both triangles are similar because 2 is just smaller than the big one 1 is similar because they are facing different way's but are similar to each other
