The equation is 2x+3=7
2x +3=7
-3 -3
2x=4
divide both sides by 2
x=2
the answer is 2
Answer:a=81/2 or 40.5
Step-by-step explanation:
(d1 x d2)/2=a
Answer:
Wilson is 6 older than mary
w=6+m
wilson is 10 less than 5 times mary
w=-10+5m
w=5m-10
so now we set them eqal to each other since both equal w
m+6=w=5m-10
m+6=5m-10
minus m both sides
6=4m-10
add 10 to both sides
16=4m
divide both sides by 4
4=m
sub back
w=m+6
w=4+6
w=10
wilson=10
mary=4
the correct method is math
Answer: The reason why is because the numbers you are multiplying are both less than 1 so it has to be less the factors
