Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5+5(9b - 7)
FIRST CASE (JUST EVALUATION)
Given the expression
Therefore, we conclude that:
SECOND CASE (Finding the value of b)
Assuming we have to determine the value of b
As we have determined
so substituting in the equation
Add 30 to both sides
Simplify
Divide both sides by 45
Simplify
Therefore, the value of b = 2/3
Y = 7x - 10 . . . (1)
y = -3 . . . (2)
Putting (2) into (1) gives:
-3 = 7x - 10
7x = -3 + 10q = 7
x = 7/7 = 1
Therefore, solution = (1, -3)
Answer:
∴ opposite side = √108
Step-by-step explanation:
Here hypotenuse = 12 ft
It is a right angled triangle.
here triangle ABC in which ∠ C = 60°
∠B = 90°
so ∠A = 180° -( 90 +60)
= 180 - 150
= 30°
cos 60° = adjacent side ÷ hypotenuse
= x ÷ 12
=
12 = 2 x
∴ x = 6
adjacent side = 6
hypotenuse ² = adjacent side² + opposite side²
12² = 6² + opposite side²
144 - 36 = opposite side ²
108 = opposite side²
∴ opposite side = √108
Answer:
$381.29
Step-by-step explanation:
10000(1+.18)5
10000(1.18)5
Amount due $22877.58
since 5 years x 12 months =60 months
monthly payment is 22877.58÷60 = $381.29
