Answer:
y = -7x + 17
Step-by-step explanation:
you want to isolate the 'y' variable, start by distributing -7 on the right side
y + 4 = -7x + 21
now subtract 4 from each side
y = -7x + 17
Given :
Martin drinks 1/4 of a litre of juice each day.
Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.
To Find :
Martin buys enough juice to last for 2 weeks (14 days).
What is the lowest price Martin can pay for this juice.
Solution :
Amount of litre used in 14 days is :
V = 14× ( 1/4 )
V = 3.5 liter
Lowest price to pay is :
P = 2 × Cost of one 2 L carton
P = £(2 × 3.60)
P = £7.2
The lowest price Martin can pay for this juice is £7.2 .
Hence, this is the required solution.
It 13 because you subtract 6 from 74.25 and then divide by 5.25

The lcm of these two give numbers is 40
Option C
This is true! Because in order to add you have to multiply 2 to the 1/2 fraction to both numerator and denominator. That would then make the fraction 2/4and 2+3 is 5and since the denominator doesn't change, it would be 5/4.
