2/5 + 1/3, Whats The Answer?

2 answers:

8 0

Hello! To solve this problem, we'll need to find a common denominator. 5 and 3 both fit into 15, so let's adjust the numerators accordingly.

2/5= 6/15 1/3= 5/15

When you add fractions, only the numerator changes.

6/15 + 5/15 = 11/15

Hope this helps! ^^

Take the 2/5 and multiple it by 3 to get 6/15....then take the 1/3 and multiple it by 5 to get 5/15. Then add this together (6/15+5/15=....) to get 11/15

$\frac{x {}^{0}y {}^{ - 3} }{x {}^{2}y {}^{ - 1} } \\ = \frac{1y {}^{ - 3} }{ {x}^{2}y {}^{ - 1} } \\ = \frac{1 \times 1}{ {x}^{2} y {}^{2} } \\ \\ = \frac{1}{ {x}^{2}y {}^{2} }$

Step by Step Explanation:

Evaluate the power: Any non-zero expression raised to the power of 0 equals 1
Simplify: Simplify the expression
Calculate the product: Any expression multiplied by 1 remains the same.

Answer:

1. $x^\circ= 7^\circ$

2.(a)Therefore , Side LJ =side CA

(b) BC = KL

Step-by-step explanation:

we know that, vertically opposite angles are congruent .

$\therefore (x+16)^\circ= (4x-5)^\circ$

$\Leftrightarrow 4x^\circ-x^\circ= 5^\circ+16^\circ$

$\Leftrightarrow 3x^\circ= 21^\circ$

$\Leftrightarrow x^\circ= 7^\circ$

(a)SAS = side,angle , side

Given ,side AB = side KJ

and ∠CAB= ∠LJK

All Pythagorean Triples are unique.

Since side AB = side KJ

Therefore , Side LJ =side CA

It satisfies SAS postulate ThereforeΔABC≅ΔKJL

(b)

HL Theorem: If hypotenuse and one leg of of a right triangle are congruent to the hypotenuse and one leg of of other right triangle , then the triangle congruent.

Since,

All Pythagorean Triples are unique.

Then hypotenuse of ΔABC=ΔLKJ ⇔BC = KL
