Answer:

Marcis answered 44 questions correctly that was 5 more than Donovan.

Step-by-step explanation:

Teacher gave a test paper with 50 questions, each worth the same number.

Donovan got 39 points out of 50 points.

Percentage marks that Donovan got = \frac{\text{Marks obtained}}{\text{Total marks}}\times 100

= \frac{39}{50}\times 100

= 78%

If Marcis scored 10% more then his percentage of marks will be = 78 + 10 = 88%

Now we will calculate the marks Marcis obtained.

Since 88% means, out of 100 marks Marcis scored 88 but the test paper was of total 50 marks then the marks scored by Marcis will be

= \frac{88}{2}

= 44

Marcis scored more than Donovan = 44 - 39 = 5

Can someone please help me figure out how to solve for x?​
Anna007 [38]

Answer:

x=30

Step-by-step explanation:

Both triangles in this figure are similar. Therefore, we can set up the following proportion:

\frac{21}{x}=\frac{14}{20}.

Cross-multiply to solve:

14x=21\cdot 20,\\x=\frac{21\cdot20}{14},\\x=\fbox{$30$}.
