Answer:
7
Step-by-step explanation:
7x5=35
The expression -4 (-11 + 4n) – 3(- 2n + 9) is equivalent to the expression 17 — 10n.
<h3>What is an equivalent expression?</h3>
The equivalent is the expressions that are in different forms but are equal to the same value.
The expression is given below.
⇒ -4 (-11 + 4n) – 3(- 2n + 9)
On simplifying, we have
⇒ 44 – 16n + 6n – 27
⇒ 17 — 10n

Answer:
Step-by-step explanation:
The sum of the measures of the angles in a triangle is 180°.
X + Y + Z = 180°
84° +(r +59)° +(r +51)° = 180°
2r +194 = 180 . . . . . . . . . divide by ° and simplify
2r = -14 . . . . . . . . . . subtract 194
r = -7
Then the measure of Y is ...
Y = (r +59)° = (-7 +59)°
Y = 52°

<em>Additional comment</em>
Z = 44°
