Answer:

x = 1/2

b = 12

Step-by-step explanation:

In order to solve for x you have to divide by x

2 = 4x  divide by x

2/4 = x

simplify and you get 1/2

same thing goes for b. You need to leave b by itself. so subtract 24 from both sides and you get -12. divide both sides by -b and a negative divided by a negative turns into a positive b by it self holds a value of 1

Answers

Answer:

Option 3

Step-by-step explanation:

the symbol your question is showing is "greater than or equal to"

when a line includes "or equal to", the circle will be filled in. also, since the symbol is going towards 5, it is considered a greater than symbol. so, you'd want to choose the option with a filled in circle and an arrow pointing to the right.

since option 3 has a filled in circle and has its arrow pointing towards the positive (or right) side of the line, it should be option 3.

Answers

Answer:

the number of hours does sidney skate in all is 9.8 hours

Step-by-step explanation:

The computation of the number of hours does sidney skate in all is as follows:

[tex]= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}[/tex]

= 9.8 hours

Hence, the number of hours does sidney skate in all is 9.8 hours
