Step-by-step explanation:
since
25⁰= 1 minute
x⁰ = 11 minutes
cross multiply
25 x 11= x
x= 275⁰
temperature after being turned on=275⁰
temperature after 11 minutes= 275⁰ + 75⁰= 350⁰
temperature(x) after being turned on
25tt=x
temperature (x) after minutes
x= 25tt + 75⁰
Answer:
180 coins
Explanation:
N = number of nickels (no nickels spent)
D = number of dimes initially saved
D' = number of dimes left after spending
1) N = D + 43
2) D' = D - 17
3) N = 2*D' = 2*(D - 17)
Set equations 1) and 3) equal to each other and solve for D:
D + 43 = 2*(D - 17)
D + 43 = 2*D - 34
D = 43 + 34 = 77
N = D + 43 = 77 + 43 = 120 nickels left
D' = D - 17 = 77 - 17 = 60 dimes left
Total coins left = 120 + 60 = 180 coins (I hope this is not too confusing for you)
Yes it is a least 75 stories tall and.....
It’d be 12.458 , rounded to the nearest tenth makes it 12.5. Hopefully, I helped.
Answer: 4, 1
Step-by-Step Explanation:
Let the First Number be ‘x’
Let the Second Number be ‘y’
Framing 2 Equations :-
=> 3x + 2y = 14 (Eq. 1)
=> 2x - y = 7 (Eq. 2)
Multiplying Eq. 2 by 2 :-
=> 4x - 2y = 14 (Eq. 3)
Adding Eq. 1 and Eq. 3 we get :-
7x = 14 + 14
7x = 28
x = 28/7
=> x = 4
Therefore, x = 4
Substitute value of ‘x’ in Eq. 1 :-
3x + 2y = 14
3(4) + 2y = 14
12 + 2y = 14
2y = 14 - 12
2y = 2
y = 2/2
=> y = 1
Therefore, y = 1
Hence,
First Number = 4
Second Number = 1
