David, Egil and Frances share money in the ratio 2:7:9. Frances gets ?80 more than David. Explain how you know Egil gets ?80.
Natalija [7]

Step-by-step explanation:

We have been given that David, Egil and Frances share money in the ratio 2:7:9.

Let 2x, 7x and 9x be the amounts of money that David, Agil and Frances get respectively.  

We are told that Frances gets $80 more than David. So we can write this information in an equation as:

9x=2x+80

Now let us solve for x.

9x-2x=80

7x=80

x=\frac{80}{7}

Now let us substitute x=\frac{80}{7} in 7x (amount of money that Egil gets).

\text{ Amount of money that Egil will get}=7\cdot \frac{80}{7}

Upon cancelling out 7 from numerator and denominator we will get,

\text{ Amount of money that Egil will get}=80  

Therefore, Egil will get $80.

It would be 20 hrs because if you put them both in an equation aka y=25x+100 and y=30x just plug in numbers into the x until they both have the answer which in this case is 20

Can someone explain the process of how to do this ACT math?
hammer [34]

Answer:

Step-by-step explanation:

∠D = ∠B     {opposite angles of parallelogram are equal}

∠D = 40°

In ΔDCA

∠DCA + ∠D + ∠CAD = 180   {Angle sum property of triangle}

57 + 40 + ∠CAD = 180

       97 + ∠CAD = 180

              ∠CAD= 180 - 97

∠CAD = 83°

Two hundred people attended the history museum exhibit on Monday. Twenty-five of the people who attended the exhibit were survey
galben [10]

Answer:

96

Step-by-step explanation:

Total number of people attending the history museum is 200

Surveyed people are 25

Out of the 25, 12 people said yes

Therefore; the fraction which said yes = 12/25

To find the total number of people expected to say yes out of those that attended the history museum;

Fraction of the sampled that said yes × total number of people that attended.

= 12/25 × 200

=  96
