Step-by-step explanation:
<u>Simplify</u>
- 6√20 + 8√5 - 5√45 =
- 6√4(5) + 8√5 - 5√9(5) =
- 6(2)√5 + 8√5 - 5(3)√5 =
- (12 + 8 - 15)√5 =
- 5√5
Answer:
The solution set is (-20/9, -95/9)
Step-by-step explanation:
To solve using the substitution method, start by solving the second equation for y.
1/3y = 7/3x + 5/3
y = 7x + 5
Now that we have this, we can plug it in for y in the first equation. Then we can solve for x.
-4x - 2(7x + 5) = 30
-4x - 14x - 10 = 30
-18x - 10 = 30
-18x = 40
x = -20/9
Now that we have the value of x, we can solve for y by inputting the x value into either equation.
-4x - 2y = 30
-4(-20/9) - 2y = 30
80/9 - 2y = 30
80/9 - 2y = 270/9
-2y = 190/9
y = -95/9
Step-by-step explanation:
Set up a proportion.
x/10=110/100
x=11
Set up a proportion.
3.5/50=y/100
y=7
24×1/6 =24/6 = 4
