Answer:
300
Step-by-step explanation:
X^2=10×10=100
3×100=300
4x-30=2x+50
+30 +30
4x=2x+80
-2x -2x
2x=80
/2 /2
X=40
4(40)-30=130°
2(40)+50=130°
180-130=50°
Angle 7=50°
Answer:
(x, y) = (-6, 3)
Step-by-step explanation:
Maybe you want to solve ...
Use the first equation to substitute for y in the second:
2x +3(-2x -9) = -3
2x -6x -27 = -3
-4x = 24 . . . . . . . . . add 27, simplify
x = -6 . . . . . . . . . . . divide by -4
y = -2(-6) -9 = 12 -9 = 3
The solution is (x, y) = (-6, 3).
Answer:
I am not completely sure with this
Step-by-step explanation:
L restaurant=6 + M
N Restaurant= 2 x L+M
Total dumplings= 72= (6+M) + M + 2x L+M
Dumplings in N restaurant=
suppose m=2
so L= 6+M=8
so L and M will be 10=8+2
N=10 x 2= 20
so u should try and find out like that
Im in elementary school so im not sure
