Answer:
(a+b)(c+d)=a c+a d+b c+b d is the formula
Step-by-step explanation:
Answer:
I believe RS is 38.
Step-by-step explanation:
RT is 50, which is the total length of the number line. ST is 12, which is one part of the line. To find RS. I believe you have to subtract 50-12 to get the length of the missing part. which is RS.
50-12 = 38
<span>3(5x + 4) - 20 - 13x = -4
first use the distributive property with </span><span>3(5x + 4)
15x+12-20-13x=-4
combine like terms
2x-8=-4
add 8 to both sides
2x=4
divide both sides by 2
x=2</span>
For proportionality constant problems, set up the equation as,
,
Where x and y are the two variables you are comparing and <em>K </em>is the proportionality constant. If we take <em>Caramel Corn </em>values as x and <em>Cheddar Corn </em>values as y, and then solve for <em>K </em>for each ratio lines, we will get the same answer. Let's check.
,
, and
.
Hence, the proportionality constant, in this case <em>K,</em> is equal to
or 1.5. First answer choice is correct.
ANSWER: 1.5
