Answer:
x = -9
y = 2
Step-by-step explanation:
x + y = -7 then x = -y - 7
-x + 4y = 17
substitute for x:
-(-y - 7) + 4y = 17
reduce:
5y = 10
y = 2
x = -2 - 7
x = -9
check:
-9 + 2 = -7
-7 = -7
-(-9) + 4(2) = 17
17 = 17

Answer:
Number pencils Ava bought = 2
Explanation:
Price of pen = 2 $
Price of pencil = 1 $
Total money spent = 12 $
Let the number of pen be a and number of pencil be b.
2 a + b = 12 -----------------------------------Equation 1
We have, she bought 3 more pens than pencils
a - b = 3 -------------------------------------- Equation 2
Equation 1 +Equation 2,
2 a + b + a - b = 12 + 3
3a = 15
a = 5
Substituting in equation 2
5 - b = 3
b = 2
Number pencils Ava bought = 2
The ratio of the sides will be constant. Then the value of the length of line segment SA will be 3 ft.

<h3>What is the triangle?</h3>
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangles ΔABC and ΔSBT are the similar triangles.
Then the ratio of the sides will be constant.
BS / SA = BT / TC
10 / SA = 9 / 2.7
SA = 3
Then the value of the length of line segment SA will be 3 ft.
