I know this because 7+7=14 and 3+3=6. Then 6+14=20.
Answer:
20
Step-by-step explanation:
How to find the perimeter of a rectangle:You add the same number twice to both numbers, then add the total of both numbers and that will get you your answer.
In this equation:
Add the same number twice.
[tex]7+7=14[/tex][tex]3+3=6[/tex]Then you add both numbers up.
[tex]14+6=20[/tex]Therefore your answer is [tex]20[/tex].

Which equation has a slope of –52 and a y-intercept of –2?
A. –5x – 2y = –4
B. –5x – 2y = 4
C. 5x + 2y = 4
D. 5x + 2y = –4
Answers
Answer:
I'm sure there might be a typo in the question (AKA the slope is -5/2)
but the answer would be
D
Step-by-step explanation:
y= mx+ b
where m is the slope, and b is the y intercept
y= -52x -2
..........
5x + 2y = –4
2y= -5x -4
y= - 5/2x -2
[tex]y = - \frac{5}{2} x - 2[/tex]

What is the solution to the system of equations? One-fourth x minus one-half y = 8 One-half x + three-fourths y = negative 5 (–8, –12) (–8, 12) (8, 12) (8, –12)
Answers
Answer:
Step-by-step explanation:
x/4-y/2=8, x-2y=32, x=32+2y
x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2
32+2y=(-20-3y)/2
64+4y=-20-3y
7y=-84
y=-12, since x=32+2y
x=32+2(-12), x=32-24=8
So the solution is the point (8, -12)
Answer:
its (8, -12)

Could be because in the first bag there is 10 silver and 9 blue,and both have very close numbers.
