$5 per hour
Explanation:
25 divided by 5 is 5
50 divided by 10 is 5
So Brent earns $5 per hour
Question 10: P=28cm
if l=8 and w=6
Then (8+6)=14
2(14) so 14x2 = 28
So therefore P=28cm
Step-by-step explanation:
y=kx
say that y is the original prince and x is the sale price
15=k(10)
15/10=k
3/2=k
you can check with the next problem to check if it is the same
25=k(20)
25/20=k
5/4=k
so you take 5/4-3/2=-1/4 so the constant is -1/4
Hope that helps :)
Answer:
If the sign before the no. is same then they will get added and the resultant will have the same sign too.
Since before 28 and 12 , both of them have the negative sign , they will get added and the sign of their resultant will be negative too.
So , -28-12 = -40
Now, if the sign before the no.s are different then there will be subtraction, and the sign before the highest no. will be the sign of the resultant.
So,( -28)+38+(-12)
= -28+38-12
= -40+38
= -2
We know that 40> 38
sign before 40 is negative, therefore, their resultant i.e 2 will also get the negative sign
I hope this helps you...
Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
