What is the value of y?

Mathematics
1 answer:
nika2105 [10]3 years ago
4 0

Answer:

y =24

Step-by-step explanation:

The exterior angle is the sum of the opposite interior angles

y+18  + 3y -41  = y+49

Combine like terms

4y -23 = y+49

Subtract y from each side

4y -y -23 = y+49-y

3y -23 = 49

Add 23 to each side

3y -23+23 = 49 +23

3y = 72

Divide by 3

3y/3 = 72/3

y =24

Anna35 [415]

Answer:

Therefore the amount in the 4% savings account = $550

Step-by-step explanation:

i) the total amount = $1500

ii) let the amount placed in the 4% interest savings account = x

iii) let the amount placed in the 5% interest savings account  = y

iv) therefore fro i) we can say  x  +  y = 1500

v) the total interest gained = $69.5

vi) therefore we can write 0.04x + 0.05y = 69.50

vii) multiplying equation vi) with 100 we get 4x + 5y = 6950

viii) Multiplying the equation in iv) by 5 we get 5x + 5y = 7500

ix) Subtracting equation in vii) from equation in viii) we get x = $550

x) Therefore the amount in the 4% savings account = $550
