Answer:
(-3, 0)
Step-by-step explanation:
Let's solve this system using the elimination by addition/subtraction method. Begin by writing the two equations one above the other:
5x +2y =-15
2x - 2y =-6
Notice that the y terms cancel each other out:
5x +2y =-15
2x - 2y =-6
------------------
7x = -21
Dividing both sides by 7 results in x = -3.
Subbing -3 for x in either of the given equations leads to finding y:
5(-3) + 2y = -15, or -15 + 2y = -15. This results in 2y = 0, or y = 0.
The solution is (-3, 0).
Well i believe its 23 my son
Answer:
here, 1m= 39.37 inches
or, 39.37 inches =1m
or, 3000 inches = 3000÷39.37 m
therefore, the measurement in m is 76.20015 m
hope it will help uh..
Answer:
60 degrees
Step-by-step explanation:
We know that a right triangle is 90 degrees
We have one angle given of 30 degrees
90 degrees - 30 degrees (known angle) = 60 degrees (unknown angle)
Therefore the unknown angle is 60
Please mark me brainliest
Step-by-step explanation:
triangle area is bh/2
(10 x 22)/2=110
area of big rectangle is
length x width=area
19 x 9=171
area of smaller rectangle is
length x width = area
9 x 6=54
add up all areas
110+171+54=335
Hope that helps :)
