Let y=f(x)
y=4x-12Now interchange the variables
x=4y-12The y we need now
x+12=4yDivide both sides by 4

Which equation is equivalent to 0.3y +0.4(25 - y) = 6.8 ?
Answer
y = 32
Step-by-step explanation:
Let's solve your equation step-by-step.
0.3y+0.4(25−y)=6.8
Step 1: Simplify both sides of the equation.
0.3y+0.4(25−y)=6.8
0.3y+(0.4)(25)+(0.4)(−[tex]\frac{-0.1y}{-0.1} =\frac{-3.2}{-0.1}[/tex]y)=6.8(Distribute)
0.3y+10+−0.4y=6.8
(0.3y+−0.4y)+(10)=6.8(Combine Like Terms)
−0.1y+10=6.8
−0.1y+10=6.8
Step 2: Subtract 10 from both sides.
−0.1y+10−10=6.8−10
−0.1y=−3.2
Step 3: Divide both sides by -0.1.
-0.1y/-0.1=-3.2/-0.1
y=32

A pet store has 15 birds and 75 fish.
In simplest form, what is the ratio of birds to fish in the pet store?
O1/6
O1/5
O5/1
I don't know
Answer:
1/5
Step-by-step explanation:
For every bird in the store there will be 5 fish.
Because there is 5 times more fish then birds.
Using the ratio concept, the number of birds to fish expressed as a ratio is 1/5
Given the Parameters :
Number of birds = 15 Number of fishes = 75Ratio of the number of birds to fish can be expressed thus :
Number of birds : Number of fishes15 : 75
Divide both sides by 15
1 : 5
Hence, the ratio of birds to fish is 1/5

Solve 5x + 2 = 22
Solve 2x-5=7
Solve 2x+5=12
Answer:
x = 4
x = 6
x = 7/2
Step-by-step explanation:
Solve 5x + 2 = 22:
5x+2-2=22-2 (subtract 2 from both sides)
5x=20
x=4
Solve 2x-5=7
2x-5+5=7+5 (add 5 to both sides)
2x=12
x=6
Solve 2x+5=12
2x+5-5=12-5 (subtract 5 from both sides)
2x=7
x= 7/2
=> 5x + 2 = 22
=> 5x = 22 – 2
=> 5x = 20
=> x = 20/5
=> x = 4
Solve 2x-5=7=> 2x - 5 = 7
=> 2x = 7+5
=> 2x = 12
=> x = 12/2
=> x = 6
Solve 2x+5=12=> 2x + 5 = 12
=> 2x = 12-5
=> 2x = 7
=> x = 7/2
The measure of an angle is 15.8°. What is the measure of its complementary angle?
Answer:
x = 74.2°
Step-by-step explanation:
Complementary angles are two angles whose sum is 90°.
Let x = the second angle
15.8° + x = 90°
x = 90 - 15.8°
x = 74.2°
