Answer:
x=-5.5 y=5.5
Step-by-step explanation:
The elimination or substitution would help.
2y=11
y=11/2
5x+3(11/2)=-11
5x+16.5=-11
-16.5
5x=-27.5
x=-5.5
Answer:
<h3>A). O is parallel to q </h3>
if angle 2 is congruent to 6 them the slope of line o and q is equal
that is line o is parallel to q
Answer:
7
Step-by-step explanation:
"a certain whole number" is a number that we don't know, so pick a variable, let's use n
"Twice" means two times, so we'll use 2n for this.
"subtracted from" means the 2n will be AFTER the minus sign.
____ - 2n
What goes in front? "3 times the square of the number" 3n^2
Now we have 3n^2 - 2n
Lastly, we see the result is 133. So this gives us:
3n^2 - 2n = 133 To solve, subtract 133 from both sides of the equation.
3n^2 -2n - 133 = 0 Next FACTOR.
(3n + 19)(n - 7) = 0
3n+19=0 and n-7=0
n=-19/3 and n=7
Since we are looking for a whole number choose n=7
Answer:
D) 5 1/6 < 5 13/30 < 5 68/90
Step-by-step explanation:
The best way to determine which value is greater is to find the decimal form of each fraction.
5 1/6 = 5.16...
5 13/30 = 5.43...
5 68/90 = 5.75...
