C 1:3
15:45 can be simplified by dividing by 15 to give you a ratio of 1minute if commercials for every 3 minutes of the actual show
3(5b-1)=5
Get rid of the brackets
15b-3=5
add 3 to both sides of the equation
15b=8
divide both sides of the equation by 15
b=0.53
4(3y-1)=20
12y-4=20
12y=24
y=0.5
Answer:
36π mm²
Step-by-step explanation:
Please, Mark, it's π or pi, not pie.
Formula for the area of a circle: A = πr²
so, if the radius is 6 mm, the area is A =π(6 mm)² = 36π mm²
Answer:
The equation would be y = 3/2x - 1
Step-by-step explanation:
To find the answer in slope-intercept form, simply solve for y.
4x-4y/2=x+2 ----> Subtract 4x from both sides
-4y/2=-3x+2 ----> Multiply both sides by 2
-4y = -6x + 4 -----> Divide by -4
y = 3/2x - 1
Answer:
x=4, y=1
Step-by-step explanation:
We can solve this set of equations using elimination.
Multiply the first equation by 3:
Multiply the second equation by 5:
Now we take
Therefore, .
To solve for x, substitute y=1 into the second equation.
Hence, .
