Answer:
-15
Step-by-step explanation:
so to start you must distribute negative two times negative two equals positive four,
so now your equation looks like this,
2^2 +4+4-3^3
then you need to do the exponents,
2 x 2 = 4
3 x 3 x 3 =27
now it looks like this
4+4+4-27
12 - 27
-15
Hope that helps!
Answer:
Judy is 16 years old
Step-by-step explanation:
J = Judy's age
A = Adams age
J = 2A
Six years ago (subtract 6 from the ages)
(J-6) = 5*(A-6)
Distribute
J-6 = 5A - 30
Substitute J = 2A
2A -6 = 5A -30
Subtract 2A from both sides
2A-2A -6 = 5A-2A -30
-6 = 3A -30
Add 30 to each side
-6+30 = 3A-30+30
24 = 3A
Divide by 3
24/3 = 3A/3
8 = A
Adam is 8 years old now
We need to find Judy's age
J = 2A
J = 2*8
J = 16
Judy is 16 years old
In order to find the answer to the question u need to get x by its self
Answer:
9x/4= -9
Mutiply by 4 for both sides.
4(9x/4) cross out 4 and 4, divide by 4 and then becomes 9x. (-9)(4)= -36
9x= -36
Divide by 9 for both sides
9x/9= -36/9
x= -4
