You have the correct x and y values. Nice work.
x/3 = 3/4
x*4 = 3*3
4x = 9
x = 9/4
AC = AD+DC
AC = 4+x
AC = 4+9/4
AC = 16/4 + 9/4
AC = 25/4
AB^2 + BC^2 = AC^2
5^2 + y^2 = (25/4)^2
25 + y^2 = 625/16
y^2 = 625/16 - 25
y^2 = 625/16 - 400/16
y^2 = 225/16
y = sqrt(225/16)
y = 15/4
Answer: D
The answer is ( 7, )
Step-by-step explanation:
Set the equations equal to each other. 3x - 28 = -3x + 14
Bring values over. 3x (+3x) - 28 = -3x + 14 (+28)
Add values together. 6x = 42
Divide by 6. x = 7
2*y + 5*x < 2 hours But the units are not the same. The left side contains minutes and the right hours.
2y + 5x < 2*60
2y + 5x < 120 <<<<< Answer
Answer:
11 2/8
Step-by-step explanation:
Turn to same fraction using multiplication
5 4/8 + 5 6/8
Add whole numbers and fractions sepperatly
5 + 5 + 4/8 + 6/8
10 + 10/8
10 + 1 2/8
