Fruit : yoghurt : total
2 : 3 : 2 + 3
2 : 3 : 5
5 parts = 185
1 part = 185 ÷ 5 = 37
3 parts = 37 x 3 = 111g
The mass of the yoghurt is 111g
1. After 5.5 hours. 2. Tickets in section A cost $8
Answer:
(8, -22) All real numbers
Step-by-step explanation:
So since we already have the value of y lets Substitute;
3x + (-4x + 10) = 2
Distribute;
3x - 4x + 10 = 2
Collect like terms;
-1x + 10 = 2
Subtract 10 from both sides;
-1x = -8
Divide both sides by -1
x = 8
So now lets get the actual value for y by substituting x;
y = -4(8) + 10
y = -32 + 10
y = -22
(x, y) = (8, -22)
Answer:
Step-by-step explanation:
In this case we know the composition of f and g is
Thus if we change x by 3 we get
1st let's calculate r the common ratio:
r = (-20)/4 = (100/-20) = -5
Value of nth term = a₁.rⁿ⁻¹, where a₁= 1st term and n, the rank
Value of nth term = 4r⁽⁷⁻¹⁾ = 4.(-5)⁶
Value of nth term = 62,500
