Solve for a. 0.25a+0.5=4.5

The correct answer is a = 16.

Step-by-step explanation:

Step 1: Subtract 0.5 from both sides.

0.25a + 0.5 − 0.5 = 4.5 − 0.5

0.25a = 4

Step 2: Divide both sides by 0.25.

0.25a/0.25 = 4/0.25

a = 16

16

Step-by-step explanation:

0.25a+0.5=4.5

Collect like terms

0.25a=4.5-0.5

0.25a=4

Convert 0.25 to fraction

That gives 25/100

25/100=1/4

So we have

1/4×a=4

Cross multiply

a= 4×4

a=16

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
