14. 6/10
To solve this, multiply both numbers (numerator/dominator) by 2. It is the same amount, just written differently.
15. Lynn has more ribbon
This one is a little trickier. Find the fraction with the smallest dominator (bottom number) and multiply it by 2 to get 8. Then multiply the numerator (top number) by 2 as well. It ends up now being 6/8.
Answer:
x^2-5x+4
Step-by-step explanation:
(x-3)^2+(x-3)-2
x^2-3x-3x+9+x-3-2
x^2-6x+9+x-5
x^2-5x+9-5
x^2-5x+4
Answer:
m+n=23
Step-by-step explanation:
the modes m and n have to be data points more than 1 time, but equal
if there are 7 data points, then there are 4 unknown left/2 2 each
(2m-3+m+12+3n+2+m+m+n+n)/7=18
(3m+9+3n+2+m+m+n+n)/7=18
(5m+5n+11)/7=18
(5/7)*m+(5/7)*n+11/7=126/7
(5/7)*m+(5/7)*n=115/7
5m+5n=115
m+n=115/5
m+n=23
Answer:
16
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
y(y² + 4y + 16) - 4x(y² + 4y + 16) ← distribute both parenthesis
= y³ + 4y² + 16y - 4xy² - 16xy - 64x
Compare - axy to - 16xy ⇒ a = 16
