Its C.
Negative x Negative is positive, so its not A or D.
Positive x Positive is Positive, so its not B either.
C is your option because Positive x Negative is Negative, and vice verca.
X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.
Answer:
5
Explanation:
5 squared is 25. 25 times 2 is 50. 50 minus 3 is 47.
Hope this helps explain what was needed to be solved! :)
Answer:
The solution is -13p+12.
Step-by-step explanation:
You have to combine like terms to solve this expression, also shown below:
7p+−20p+12
(7p+−20p)+(12)
−13p+12
. So, the solution is -13p+12.
