Answer:
nine because i did this same one before
Answer:
b. -3
Step-by-step explanation:
Cross multiply
5x = 3(x - 2)
Distributive property
5x = 3x - 6
Subtract 3x from both sides
2x = -6
Divide both sides by 2
x = -3
Let X = number of Giraffes
Number of elephants = 3X - 4
Because it was stated that there are more than 23 elephants, the number should not fall below 23.
The algebraic expression would be:
3X - 4 = 23
To get X; Transfer -4 to the other side, changing its sign to positive.
3X = 23 + 4
3X = 27
To get X; Divide both sides by 3
X = 27 / 3
X = 9
Since X represents the number of giraffes, then, there are 9 giraffes in the zoo.
To Check: Substitute X with 9 in the algebraic expression.
3X - 4 = 23
3(9) - 4 = 23
27 - 4 = 23
23 = 23 EQUAL
Answer: Rounded: 236 seconds
Not rounded: 236.07 seconds
Step-by-step explanation: We know that it takes the car 54.9 seconds to travel one mile, and we know that 1 times 4.3 is 4.3, so 4.3 times 54.9 equals 236.07 seconds.
7. Alternate interior
8. Congruent
9. Work:
6x - 16 = 2x + 40
4x = 56
x = 14
