This is fairly simple, you have to work backwards, you first multiply the 40 by 9/5, or 1.8 and get 72. Then add 32, and get 104 F
Answer: Y = 4
the output is 4
Step-by-step explanation:
substitute the given input value, 3, for x and solve
Y= 10 -2x
Y = 10 -2(3) multiply -2 × 3 to get -6
Y = 10 -6 . subtract
Y = 4
Answer:
It will take 3 days for their bird feeders to contain the same amount of bird seed
Step-by-step explanation:
Let the number of days it will take their bird feeder to contain the amount of bird seed be x
For Edith, the amount of birdseeds that will be left after x days will be;
4 1/2 - 3/4(x)
= 9/2 - 3x/4
For June, the amount of birdseeds that will remain after x days will be;
3 - 1/4(x)
= 3 - x/4
Since after x days, the amount of birdseeds will be equal;
Mathematically;
9/2 - 3x/4 = 3 - x/4
Let’s work with decimals to make things easier;
4.5 - 0.75x = 3 - 0.25x
4.5 -3 = -0.25x + 0.75x
1.5 = 0.5x
x = 1.5/0.5
x = 3
