B. To translate up or down the number must be outside of the absolute value bars
Answer:
25 , 17
Step-by-step explanation:
Let the unknown two numbers be x & y.
According to the question,
Sum of 2 numbers is 42.
x + y = 42 ⇒ ( 1 )
Their difference is 8.
x - y = 8 ⇒ ( 2 )
First let us find the value of x.
( 1 ) + ( 2 )
x + y + x - y = 42 + 8
2x = 50
Divide both sides by 2.
x = 25
And now let us find the value of y.
x + y = 42
25 + y = 42
y = 42 - 25
y = 17
Therefore, the two numbers are 25 , 17

Answer:
All of the following are rational except 3.14159...
Step-by-step explanation:
Answer:
C. (2, 5)
Step-by-step explanation:
Looking at the answer choices, you can see that solving for y will tell you which choice is correct. We can eliminate x from the equations by adding 4 times the second equation to the first:
(8x -3y) +4(-2x +3y) = (1) +4(11) . . . . . adding the equations to eliminate x
9y = 45 . . . simplified; next we divide by 9
y = 5 . . . . . matches choice C

Check
8(2) -3(5) = 16 -15 = 1
-2(2) +3(5) = -4 +15 = 11 . . . . the answer checks OK in both equations
Answer:
Lemmy ; 2 7/8 miles
Step-by-step explanation:
Given that :
Distance walked by Lemmy:
Saturday = 3 1/2 miles
Sunday = 4 3/4 miles
Total distance walked by Lemmy:
3 1/2 + 4 3/4
7/2 + 19/4
(14 + 19) / 4
33 / 4
= 8 1/4
Miles walked by Ronnie : 5 3/8
Lemmy walked farther because : 8 1/4 > 5 3/8
Number of distance walked farther than Ronnie :
8 1/4 - 5 3/8
33/4 - 43/8
(66 - 43) / 8
= 23/ 8
= 2 7/8 miles
