five twice the sum of a number and 3 is the same as 3 multiplied by 1 less than twice the number. what is the number? ​
aleksklad [387]

Answer:  -4.5, but only if the phrase "five twice the sum . . ." means 5*2*(the sum of . . .).  "five twice" is confusing, so please check the question.

Step-by-step explanation:

5*2*(X + 3) = 3*(2X - 1)

10X + 15 = 6X -3

4X = -18

X  = -18/4

X = - 4.5

Half of Ethan string is equal to 2/3 of Kayla stream the total length of the string is 10 feet how much longer is Ethan string K
Verizon [17]

Answer:

10/7 feet

Step-by-step explanation:

Let e = Ethan

k = Kayla

The following equations can de derived from the equation :

1/2 e = 2/3k

multiply both sides of the equation by 2

e = 4/3k --- 1

e + k = 10 --- 2

Substitute for e in equation 2

4/3k + k = 10

7/3k = 10

multiply both sides of the equation by 3/7

k = 30/7

Substitute for k in equation 1

e = (4/3) x 30/7 = 40/7

difference in length = 40/7 - 30/7 = 10/7
