30+5=5+30 with commutative property or 30+5=35
Answer:
x = -9/4
Step-by-step explanation:
−2(x + 1/4) + 1 = 5
Subtract 2 from both sides.
−2(x + 1/4) = 4
Divide both sides by -2.
x + 1/4 = -2
Subtract 1/4 from both sides.
x = -2 1/4
x = -9/4
Answer:
x = 137
Step-by-step explanation:
Step-by-step explanation:
∠43° and ∠x° are same side exterior angles as they are on the same side as the transversal but outside the parallel lines. The 2 angles are supplementary, hence
x + 43 = 180 ( subtract 43 from both sides )
x = 137
Answer:
u will not fail i promise
Step-by-step explanation:
and the answer is the first becz we have to see the difference in arthimatic terms
6x +30 -3x +6 =12x +18
3x +36 =12x +18
3x-12x = 18 -36
-9x = -18 | -1
9x =18
x= 18/9
x=2
