Choose the inequality that represents the following graph
Answer:
Step-by-step explanation:
1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.

John has a box of nails. The box contains 65 small nails, 40 medium nails, and 45 large nails. Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box. There are 176 medium nails in Susan's box.
What is the total number of nails in Susan's box?
Answer:
326
Step-by-step explanation:
Add a nails: 65+40+45+176= The answer
660
Step-by-step explanation:
John
65s (small)
40m (medium)
45 L (large)
Susan
x small
176m
y large
From question:
Susan has a box of nails that has the same proportion of small, medium, and large nails as John's box =Meaning same ratio
John ratio. Susan
s : m : L s : m : L
65 : 40 : 45. 13 : 8 : 9
13 : 8 : 9. x : 176 : y
x = (176/8)*13
=286
y = (176/8) * 9
= 198
Total number of nails in Susan box
= x + 176 + y
= 286 + 176 + 198
=660

Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x = 5 is the answer
