The median of the first 8 prime numbers are 9
5x-5=-7y
3x+2y=-8
First, you need to rearrange the first equation so it is in the same format as the second one.
5x-5=-7y
Add 5 to both sides
5x-5+5=-7y+5
Add 7y to both sides
5x+7y=-7y+7y+5
So you have 5x+7y=5
Now you need to multiply that equation by 3
3(5x+7y=5)
15x+21y=15
Multiply the second equation by -5
-5(3x+2y=-8)
-15x-10y=40
Now add them together
15x+21y=15
+(-15x-10y=40)
---------------------
11y=55
y=5
Now plug y=5 into one of the original equations and solve for x.
3x+2(5)=-8
3x+10=-8
3x=-8-10
3x=-18
x=-6
To check the solution plug them both into the other equation:
5(-6)-5=-7(5)
-30-5=-35
-35=-35
It checks.
Hope that helps.
Answer:
$1880.48 to the nearest cent.
Step-by-step explanation:
Total after n years = P(1 + r)^n where P = initial deposit, r = the rate as a fraction.
4 5/8 % = 0.04625.
Here the total after 5 years = 1500(1 + 0.04625)^5
= $1880.48 to the nearest cent.
The answer is 27. Volume of the cube
The garden has four quarters. three quarters are planted with basil. one quarter is planted with sage. The strips represent quarters. So that means that three strips represent three quarters. Well one strip represents one quarter.
