Answer:
.50
.25
3.33
.14
Step-by-step explanation:
hope this helps
STEP 1:
identify variables and equations
x= larger number
y= smaller number
FIRST EQUATION
x + y= 42
SECOND EQUATION
y= 2x - 63
STEP 2:
substitute the y value in second equation in for y in first equation
x + y= 42
substitute y value from 2nd equation
x + (2x - 63)= 42
combine like terms
3x - 63= 42
add 63 to both sides
3x= 105
divide both sides by 3
x= 35 larger number
STEP 3:
find y value; substitute step 2 x value into either original equation
x + y= 42
35 + y= 42
subtract 35 from both sides
y= 7 smaller number
ANSWER: larger number is x= 35; smaller number is y= 7.

False. consider u1 = (0, 0, 0), u2 = (1, 0, 0), u3 = (0, 1, 0), and u4 = (0, 0, 1).

You give us the answer right now. It's the answer to :
<span>If {u1, u2, u3} does not span R3, then neither does {u1, u2, u3, u4}.

We know 623.1 because 40 times 12 = 480 add with the area of the triangle which is 1/2 * 12 *5 = 30, and the circle A=πr2=π·62≈113.09734, and add them up to equal 623.1 square feet
