1/3+4/5= 17/15
The commun multipleof 3 and 5 is 15.
1/3×5= 5/15
4/5×3= 12/15
5/12+12/15= 17/12
17/12×7= 119/84
119/84
Hope this helps! :)

Answer:
60 degrees
Step-by-step explanation:
because two inner angles equals the opposite side's outer angle, we can do this
3y + 13 + 4y = 118
we combine like terms
7y + 13 = 118
subtract
7y = 105
and then divide
y = 15
then we do the equation for A's angle
4(15) = 60
Answer:
Step-by-step explanation:
1. M is the midpoint of CD; CM = 3x - 10; MD = 6x - 22; GIVEN
2. CM = MD Definition of Midpoint
3. 3x - 10 = 6x - 22 Substitution Property
4. -3x - 10 = - 22 Subtraction Prop of Equality
5. -3x =-12 Addition Prop of Equality
6. x = 4 Division Prop of Equality
Answer: 10
Step-by-Step explanation: 7 is the width and there are two wide sides so you have 14. 34-14 is 20. Now because you have 20 left and there are two long sides you need to divide 20 by 2. 20 divided by 2 =10.
What we know:
Shape is square
Area= 150 cm²
Area=s²
What we need to find: s=side of square
Area=s²
150=s²
√150=√s²
√150=s
s≈12 cm
C. 12cm
Remember when finding the square root of a number you get a positive and negative solution. In this case, length is positive so we do not need the negative solution.
