They do not intersect, they are parallel lines.
STEP 1
Bandages: multiply number of total kits by number of bandages per kit
9 * 24= 216 bandages total
STEP 2
Antiseptic Wipes: multiply number of total kits by number of antiseptic wipes per kit
9 * 16= 144 antiseptic wipes total
STEP 3
find difference between steps 1 & 2
= 216 bandages - 144 antiseptic wipes
= 72 more bandages
ANSWER: She packed 72 more bandages than antiseptic wipes.
Hope this helps! :)
<span>3a+4x=29 (1st)
2a-3x=-9 (2nd)
multiply (1st) by 3 and (2nd) by 4
</span>9a + 12x = 87 (1st)
8a - 12x = -36 (2nd)
---------------------add
17a = 51
a = 3
<span>2a-3x=-9
</span><span>2(3)-3x=-9
6 - 3x = -9
-3x = -15
x = 5
answer
x = 5 and a = 3</span>
Answer:
15x + 25 = y
Step-by-step explanation:
$25 is a fixed cost and will have to be paid if the plumber comes and $15 times the number of hours it takes to do the repair is the variable cost. 'x' in this case is the number of hours. So the equation will be 15x + 25 = y
