A) 42x-12
6*7=42. 6*2=12
b) 21y
11+4+6=21
That'd be y = 70* (1-.00043)^t, where the rate of decrease is really 0.43% and t denotes the # of weeks.
This simplifies to y = 70*(0.00057)^t.
Answer:
The answer would be 25.
4x4=16
16+9=25
Step-by-step explanation:
I believe this is correct, if not feel free to let me know and I will fix it. I'm sorry in advance if it is incorrect.
Answer:
The value of x = 9
Step-by-step explanation:
∵ The figure has right angle and a line ⊥ from the right angle to the hypotenuse
∴ There is a relation between the ⊥ line and the two parts of the hypotenuse
∴ (⊥)² = multiplication of the two parts of the hypotenuse
∴ (6)²= 4 × x
∴ 36 = 4 × x
∴ x = 36/4 = 9
Answer:
x = 
- 4y + 12
Step-by-step explanation:
y = 2 + 
Put the 2 on the other side
y - 2 =
Square both sides
= x - 8
Expand the brackets
- 4y + 4 = x-8
Move 8 to the other side
x = - 4y + 12
