The two masses are equal, since 0.8 Kg = 800 g
Answer:
2x-24
I think that you changes the problem...
you went from a derivative to an inverse ???
y = 1/2x + 14
x = 1/2 y + 14
2x = y + 24
y = 2x-24
Step-by-step explanation:
Answer:
n ≥ 3.74
Min #of friends = 4
Step-by-step explanation:
There are some info missing. Let me say those:
Given
Cost of Headphones = $345
Grandma and Uncle will give = $45
Now let x be the donation of each friend, so x = 20, and
let y be the correct answer friends, y = 0.25
Now, let n represent the number of friends who's gonna give Benjamin $0.25.
Also, we know his Total Income must be greater than or equal to the cost for him to buy the headphone. Thus we can say:
Total Income ≥ Cost
Cost = 345
TOtal Income = 45 (from relatives) + 4n(20) (4n donation friends each giving 20) + 0.25n (n people giving 0.25 each).
Thus, we have:
Total Income ≥ Cost
45 + 80n + 0.25n ≥ 345
80.25n ≥ 300
n ≥ 3.74
Therefore, the minimum number of friends who must pay Benjamin $0.25 for each correct answer in order for him to meet his goal is 4.
Answer:
Each angle is 60°
Step-by-step explanation:
The 2 angles are equal to each other because they're alternate exterior angles:
10x - 20 = 7x + 4
10x - 7x = 4 + 20
3x = 24
x = 8
10x - 20
10(8) - 20
80 - 20
60
Since these angles are exterior angles, their angle measures are equal so they both are 60°
Answer:
-71
Step-by-step explanation:
let 'n' = a number
2(143 + 2n) = 0n + 2
2(143 + 2n) = 2
143 + 2n = 1
2n = -142
n = -71
