2x + 3(8 - 3x) = 3
2x + 24 -9x = 3
-7x = -21
x = 3
y = 8 - 3x
y = 8 - 3(3)
y = 8-9
y = -1
Check the math:
2(3) + 3(-1) = 6 - 3 = 3
Answer:
7/13
Step-by-step explanation:
Arrange the numbers so that the number of girls in year 10 is the numerator, and the total number of girls is the denominator. (140/260) Simplify this by dividing both numbers by 20.
Answer:
Step-by-step explanation:
Three feet make a yard, so 2 yards is 6 feet
If we divide the top (numerator) and the bottom (denominator) by 2 we get
÷ =
10
A composite number is a positive integer. which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... (OEIS A002808), whose prime decompositions are summarized in the following table.
Answer:
C and D
Step-by-step explanation:
So from the equation <em>y = 1.26x + 9.49</em> we can gather that <em>9.49</em> is an initial value because it has to be added to the number with a variable <em>( 1.26x)</em>
Because <em>1.26</em> has a variable of <em>x </em>and x represents a week, we know that the number<em> 1.26 </em>will increases in value depending on how many weeks have passed.
