Step-by-step explanation:
You times 9.50 by 65 which gives you 617.5 in total.
Answer:
13%
Step-by-step explanation:
we can find the percentage by dividing 5 by 37 1/2
5/37.5=0.1333333... or about 13%
Answer:
No
Step-by-step explanation:
We can plug in the ordered pair (6,-1) into the equation. Remember that 6 is the x coordinate therefore we plug it in for x and that -1 is the y coordinate so we should plug it in for y.
6x+3y=6(6)+3(-1)=36-3=33
Since 33 is not equivalent to 15, (6, -1) is not a solution to the equation.
Answer:
y = 0
x = 4
Explanation:
<u>make x the subject,</u>
x - 3y = 4
x = 4 + 3y __ equation 1
2x - 5y = 8
x = (8+5y)/2 __ equation 2
<u>using substitution method:</u>
(8+5y)/2 = 4 + 3y
8 + 5y = 8 + 6y
6y - 5y = 8 - 8
y = 0
Find x,
x = 4 + 3y
x = 4 + 3(0)
x = 4
