Use fraction models to solve two and four sevenths plus three and two fourths equals blank
jenyasd209 [6]

Answer:

6 \frac{1}{14}

Step-by-step explanation:

Write down the problem;

2 \frac{4}{7} + 3 \frac{2}{4}

Simplify

2 \frac{4}{7} + 3 \frac{1}{2}

Convert so that the fractions have a common denominator; multiply the numerator and denominator of both fractions such that the denominators are equal;

2 \frac{8}{14} + 3 \frac{7}{14}

Add the fractions;

5 \frac{15}{14}

Convert to mixed number;

6 \frac{1}{14}

Triangle NLM is reflected over the line segment as shown, forming triangle ABC. Which congruency statement is correct? ΔNLM ≅ ΔC
algol13
<span>Given that triangle NLM is reflected over the line segment as shown, forming triangle ABC.

When a point is refrected across a line, the relative distance form the point to the line of refrection is preserved. That is the distance from the point to the line of refrection is equal to the distance of the image to the line of refrection.

Thus, from the figure, it can be seen the point B is of the same distance to the line of refrection as point M, so is point A to point L and point C to point N.

Thus, </span><span>ΔNLM is similar to </span><span><span>ΔCAB

Therefore, the</span> congruency statement that is correct is ΔNLM ≅ ΔCAB</span>
