Answer:
The equation is a conditional.
y = 7.5
Step-by-step explanation:
y - 11 + 3y = 6y + 4
4y - 11 = 6y + 4
4y - 4y - 11 = 6y - 4y + 4
- 11 = 2y + 4
- 11 - 4 = 2y + 4 - 4
2y = - 15
2y ÷ 2 = - 15 ÷ 2
y = - 7.5
The rule to use: when dividing fractions, invert and multiply.
-6 ÷ -(3/4) equals -6 * -(4/3) which equals 24 / 3 which equals
8
Answer:
A. x=8, -8
B. x= -3, -7
Step-by-step explanation:
Answer: (a) isosceles (b) right
<u>Step-by-step explanation:</u>
(a) All sides of a rhombus are congruent → PN = AN
Therefore, ΔPNA has two congruent sides so is ISCOSCELES
(b) The diagonals of a rhombus are perpendicular (equal to 90°)
Therefore, ∠PEL = 90° so ΔPEL is a RIGHT triangle
