Answer:
= 22/3 + 28/5
= ((22 × 5) + (28 × 3)) / (3 × 5)
= (110 + 84) / 15
= 194/15
= 194/15
= 12 14/15
.Adding Mixed Numbers:
Convert the mixed numbers into fractions.
Use the algebraic formula for addition of fractions: a/b + c/d = (ad + bc) / bd.
<span>A is the correct answer. To find 10% of 50, divide it by 10. This gives you 5. If 5 is 10%, then 20 is 40%, because 20 is 4 x 5 and 40 is 4 x 10. </span>

------------------------------------------------------------
Define the two numbers
-----------------------------------------------------------
Let the first number be x.
Let the second number be y.
------------------------------------------------------------
Form equations and solve x and y
------------------------------------------------------------
x + 2y = 14 ------------------ (1)
2x + y = 31 ------------------ (2)
------------------------------------------------------------
Equation (1) x 2
------------------------------------------------------------
2x + 4y = 28 ---------------(1a)
------------------------------------------------------------
Equation (1a) - 2
------------------------------------------------------------
3y = 28 - 31
3y = -3
y = -1
------------------------------------------------------------
Substitute y = -1 into (1)
------------------------------------------------------------
x + 2(-1) = 14
x -2 = 14
x = 14 + 2
x = 16
------------------------------------------------------------
Answer: x =16, y = -1
------------------------------------------------------------
Answer:
197
Step-by-step explanation:
Assuming the question is asking for the sum of 14 squared and 1 cubed, 14 squared is 196 and 1 cubed is 1. Adding these together is 196+1 which gives 197.
