6.2×10³ - 4.8×10³
is the same as writing:
6200 - 4800.
The answer to 6200 - 4800 is 1400.
The answer is 1400, or 1.4×10³.
*NOT MY WORK ITS FROM SOMEONE ELSE WHO ASKED THE SAME PROBLEM*
Answer: x=15, y= 10
Step-by-step explanation:
Answer: x=15, y=10
*Note: x and y are only variables used to solve this problem, but know that the two numbers are 15 and 10.
Step-by-step explanation:
For this problem, we can use system of equations. Let's use x for one number and y for the other.
First Equation:
x+y=25
We get this equation because it states that the sum of the two numbers is 25.
Second Equation:
y=x-5
We get this equation because it says one number (y) is 5 less than the other (x).
Since we have two equations, we can use substitution method to solve.
[distribute 1 to (x-5)]
[combine like terms]
[add both sides by 5]
[divide both sides by 2]
Now that we have x, we can plug it into any of the equations to find y.
[plug in x=15]
[subtract both sides by 15]
Finally, we have our answer, x=15 and y=10.
The most logical ones would be C and D spends on ur grade I would say C though
H+s=244
h=s-38
sub s-38 for h
s-38+s=244
2s-38=244
add 38 both sides
2s=282
divide 2 both sides
s=141
sub
h=s-38
h=141-38
h=103
