50 students studying both Maths and English. 90 students study either maths or english. If 25 students study eng not maths. How
In-s [12.5K]

Answer:

15 students study math and not English

Step-by-step explanation:

lets take the # or people who study math but not English as "x"

so 90 students study math or English

25 students study English and not math

and

50 study both

since 90 students study math or English that is what our equation will equal.

so

25+x+50=90

25+50=75

75+x=90

subtract "75" from both sides:

x=15

Hope this helps!

If AB is parallel to CD, and CD = 20, BD = 6, DE = 8, what is the length of AB?
castortr0y [4]

Answer:

Option b. 35 units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

in this problem triangle ABE and triangle CDE are similar by AA Similarity Theorem

so

\frac{AB}{DC}=\frac{BE}{DE}

substitute the given values

\frac{AB}{20}=\frac{14}{8}

Solve for AB

AB=\frac{14}{8}(20)

AB=35\ units
