Answer: Lashawna scored 14 points

Step-by-step explanation:

Let M = Mary's score

L = Lashawna score

M = 28 points

And M is twice as much as L score

M= 2L

L= M/2

L= 28/2

M = 14.

Lashawna score was 14 points

What is the value of x?<br><br> Please help! Thanks!
leonid [27]

Answer:

x=75

Step-by-step explanation:

We can use proportions to solve this problem.  Put the side of the small triangle over the side of the large triangle.

42           50

------ = ----------

42+63        50+x

42           50

------ = ----------

105          50+x

Using cross products

42(50+x) = 50*(105)

2100+42x = 5250

Subtract 2100 from each side

2100-2100+42x = 5250-2100

42x =3150

Divide by 42

42x/42 = 3150/42

x = 75

Which ratio is higher 15:20 or 12:16. for 35 points
Margarita [4]

To find which ratio is higher, we can first convert the ratios into fractions (that makes it easier, at least for me) and then simplify the fractions and see which one is greater.

Since ratios are basically division, 15:20 = \frac{15}{20}, and

12:16 = \frac{12}{16}

Now we simplify these fractions. 15 and 20 have a GCF of 5, so taking out the common number gives us the simplified fraction of \frac{3}{4}.

12 and 16 have a GCF of 4, so taking out the common number gives us the simplified fraction of \frac{3}{4}. Since \frac{3}{4} = \frac{3}{4}, these ratios are the same.
