Answer:

English test score: 55

Mathematics test score: 75

Step-by-step explanation:

Let e be Mary's score on the English test.

We can say that e + 20 is her score on the Mathematics test, as the score for the Mathematics test is just the English test score but 20 higher.

Since both scores add up to 130, we can set up an equation to solve for the English test score. Since we said e + 20 is Mary's score on the Mathematics test, e + e + 20 is the total of her 2 test scores.

e + e + 20 = 130\\2e + 20 = 130\\2e = 110\\\boxed{e = 55}

This means that Mary got a 55 on her English test score.

To solve for the Mathematics test score we can substitute 55 for e in e + 20.

e + 20 = 55 + 20 \rightarrow \boxed{75}

This means Mary got a 75 on her Mathematics test.

Those are the answers

the maximum distance D in kilometers that you can see from a height H in meters is given by the formula d equals 3.5 times the s
Irina-Kira [14]
First put the words in an algebraic format or a model. D = 3.5(√H). Now determine what the question is asking. It's height. Plug in the value of D. Distance is 35 km.
35 = 3.5(√H) We want to get H by itself. First thing to get away from it is 3.5. So                      divide 35 by 3.5 And 3.5(√h) by 3.5.
10 = √H        To get rid of √ do the opposite raise to the power of 2
10² = (√H)²   
100 = H 
You must be 100 kilometers above ground to see 35 kilometers
