Answer:
small number is 14
Larger number is 31
Step-by-step explanation:
Let x = one number
Let y = the second number
x + y = 45
x = y - 17
Put y - 17 into the top equation for x
y - 17 + y = 45
2y - 17 = 45 Add 17 to both sides
2y = 45 + 17
2y = 62 Divide by 2
y = 62/2
y = 31
Area of the board divided by the time
2 x 3 = 6ft^2
15/6= 2.5mins
The greatest possible error of 18.9 is 18.95 - 18.85 = 0.1
The greatest possible error of 11 1/8 (11.125) oz is 11.1255 - 11.1245 = 0.001 = 1/1000
Answer:
x=±√−9
No real solutions.
Step-by-step explanation:
Step 1: Add 3x^2 to both sides.
27+3x2=−3x2+3x2
3x2+27=0
Step 2: Subtract 27 from both sides.
3x2+27−27=0−27
3x2=−27
Step 3: Divide both sides by 3.

x2=−9
Step 4: Take square root.
x=±√−9
