Answer:
x=-1 and y=-5
Step-by-step explanation:
ሰላም!
Given expressions let them given as two equations
- y=2+7x....... equation (1)
- -2x+6y=-28..... equation (2)
Thus, substitute y=2+7x into equation (2)

simplify it

subtract 12 from both sides

divide both sides by 40

Therefore, as we get the value of x=-1 substitute it to equation (1) and solve for variable y

To be more sure make a cross check on both of the two expressions
Thus,
1) y=2+7x .... substitute y=-5 and x=-1 and check if it is equal
-5=2+7(-1)
-5=2-5
-5=-5
2)-2x+6y=-28... substitute and check
-2(-1)+6(-5)=-28
2-30=-28... (-a)(-b)=ab
-28=-28
Hope it helps!

732−83+21−1363−11.2+133+19= −552.2
Answer:
it will be 49 because u will add four because 37+4=41 41+4=45. 45+4= 49
45/60=0.75. Speed*time=distance. 35(0.75)= 26.25 miles
Please say brainliest.
It would be 18 degrees.
5% of 360(the total number of degrees in a circle) = 18 degrees
