Answer:
2 7/10
Step-by-step explanation:
3/4+3/5=
Common Denominator: 20
Multiples of 4: 4, 8, 12, 16, 20
Multiples of 5: 5, 10, 15, 20
3x5=15
4x5=20
15/20
3x4=12
5x4=20
12/20
15/20+12/20= 27/20 = 2 7/10
Answer:
the answer to your problem would be 420
Answer:
4w+10=-w
w=-2
Step-by-step explanation:
First, write out the equation in the algebraic form to make it easier to solve. This equation written out is 4w+10=-w. Then, isolate the variable and solve. Do this by subtracting 4w from both sides. Then, divide both sides by -5.
D would equal to either 9 or －9
