y = 8 -2x
x + 2 (8 - 2x) = 1
x + 16 - 4x = 1
x - 4x = -15
-3x = -15
x = 5
If x = 5, then we can substitute in...
5 + 2y = 1
2y = -4
y = -2
Now let us check that by substituting those values in to the equation
2x + y = 8
2 (5) + (-2) = 8
That is correct so we have the right values for x and y/
Hi , we are going to begin with the numbers that are divisible with 2025 .
Basically I'm aware that 2 is not divisible , so we are going to use 3 .
2025 divided by 3 = 675 divided by 3 = 225 divided by 3 = 75 divided by 3 = 25 divided by 5 = 5
I used 5 because I cant use 3 , in other words you can divide 25 and 3 , but you will not get a whole number .I stopped when I divided 25 and 5 because I got 5 which is a [prime number] , when you are doing this type of exercises , when you see a prime number you have to stop.
So the prime factorization is 3 times 3 times 3 times 3 times 5 times 5.
Answer:
C. Infinitely many
Step-by-step explanation:
(30m/s divided by 2)x 10800 ( convert 3hr to seconds by x with 60squared)
= 162000 m ( convert m to km by dividing with 1000)
= 162 km

Answer:
flour $42 , bag of sugar $58
Step-by-step explanation:
let f represent flour and s represent sugar, then
7f + 5s = 584 → (1)
5f + 3s = 384 → (2)
Multiplying (1) by 3 and (2) by - 5 and adding will eliminate s
21f + 15s = 1752 → (3)
- 25f - 15s = - 1920 → (4)
Add (3) and (4) term by term to eliminate s , that is
- 4f = - 168 ( divide both sides by - 4 )
f = 42
Substitute f = 42 into either of the 2 equations and solve for s
Substituting into (1)
7(42) + 5s = 584
294 + 5s = 584 ( subtract 294 from both sides )
5s = 290 ( divide both sides by 5 )
s = 58
The cost of a bag of flour is $42 and cost of sugar is $58
