STatiana [176]

841 jumping jacks per 4 minutes

\frac{841~jumping~jacks}{4~minutes}

Divide both sides by 4.

\frac{841}{4} \div \frac{4}{4} = \frac{210.25}{1}

Delilah can do 210.25 (or 210) jumping jacks per minute.

I need a little help! Can someone check my work? It's a written response with linear systems.
andreyandreev [35.5K]

Answer:

I'd say you need to be more specific.

Step-by-step explanation:

"Different" doesn't tell you much.

Consider the equations ...

  • y = 2x + 1
  • 4x - 2y = -2

These equations are "different", but they are <em>dependent</em>.

_____

I'd mentally (or actually) put the equations in the same form and compare the coefficients of x and y. If they have different ratios, the system is independent and consistent.

If they have the same ratio, the system will not have a single solution. Whether there is no solution or an infinite number of solutions depends on the constant, which I would examine next.

The system above can be put in the form

  • 2x -y = -1
  • 4x -2y = -2

In both cases, the ratio of the x coefficient to the y coefficient is 2/-1 = 4/-2 = -2. This means the lines are at least parallel, if not identical. The numbers in the second equation are all 2 times the numbers in the first equation, so the equations are <em>dependent</em>, and there are an infinite number of solutions. (Both describe the same line.)

If the second equation were 4x -2y = 1, then the two equations would be describing parallel lines, so they would be called <em>inconsistent</em>.

shutvik [7]

Step-by-step explanation:

\frac{20}{48}  \times  \frac{80}{44}

Divide the fraction with 4

\frac{20÷4}{48÷4} \times \frac{80÷4}{44÷4} = \frac{5}{12}  \times  \frac{20}{11}

Reduce the number with factor 4

\frac{5}{12÷4} \times \frac{20÷4}{11} = \frac{5}{3}   \times  \frac{5}{11}

Multiply the fractions

\frac{5 \times 5}{3 \times 11}  =  \frac{25}{33}

\boxed{\green{=  \frac{25}{33}  = 0.75}}
