Answer:
40 square units
Step-by-step explanation:
This is a rhombus, so you multiply the two diagonals and divide by 2.
8x10÷2=40
Answer:
(-6,-5)
Step-by-step explanation:
X+y=-11
solve for x
x=-11-y
substiute x value into 2nd equation
2x-3y=3
2(-11-y)-3y=3
-22-2y-3y=3
-5y=25
y=-5
substitute -5 for y in either equation to find x
x+y=-11
x+-5=-11
x=-6
Answer:
$5,000
Step-by-step explanation:
Create a proportion:
11/100 = 550/x
100(550)/11
5,000= x
The answer is 18. the equation is (15 x 2) - 12. hope I helped :)
Divide any term by the term before it, and you'll get the common ratio of the geometric series.
-81/-27=3
The common ratio is 3.
