It's the correct spelling.
Answer:
B
Step-by-step explanation:
The answer is x = 10, y = 10.
Step 1: rearrange the second equation for y.
Step 2: substitute y from the second equation into the first equation.
Step 3. Calculate y.
Step 1.
<span>The second equation is: 6x + 3y = 90
Divide both sides of the equation by 3:
(6x + 3y)/3 = 90/3
6x/3 + 3y/3 = 30
2x + y = 30
Rearrange the equation:
y = 30 - 2x
Step 2.
</span>Substitute y from the second equation (y = 30 - 2x) into the first equation:
<span>15x + 9y = 240
15x + 9(30 - 2x) = 240
15x + 270 - 18x = 240
15x - 18x = 240 - 270
-3x = -30
x = -30/-3
x = 10
Step 3.
Since </span>y = 30 - 2x and x = 10, then:
y = 30 - 2 * 10
y = 30 - 20
y = 10

Answer:
B
Step-by-step explanation:
Its not A because when you plug in 0.6 in for P it gives you 6.6=1.8. (0.6)+6=1.8
Its B because when you plug in 0.6 in for P it gives you 6=6.
10(0.6)=6
Its not C because when you plug in 0.6 in for P it gives you 0.36=10.
0.6(0.6)=10
Its not D because when you plug in 0.6 in for P it gives you -0.4=0.4.
(0.6)-1=0.4
