Combine likes terms to create an equivalent expression 1/7 - 3(3/7h -2/7)
Anastasy [175]

\frac{1}{7} -3(\frac{3}{7}h -\frac{2}{7}) = \frac{7-9h}{7}

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

\frac{1}{7} -3(\frac{3}{7}h -\frac{2}{7})

We have to combine the like terms

From given expression,

\frac{1}{7} -3(\frac{3}{7}h -\frac{2}{7})

By distributive property,

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

a(b + c) = ab + bc

Therefore,

Solve for brackets using distributive property

\frac{1}{7} - (3 \times \frac{3}{7}h) + (3 \times \frac{2}{7})\\\\\frac{1}{7} - \frac{9h}{7} + \frac{6}{7}

Add 1/7 and 6/7

\frac{1}{7} + \frac{6}{7} -\frac{9h}{7}\\\\\frac{1+6}{7} -\frac{9h}{7}\\\\Simplify\\\\\frac{7}{7}-\frac{9h}{7}\\\\1-\frac{9h}{7}\\\\Simplify\\\\\frac{7-9h}{7}

Thus the equivalent expression is found

Please help me. I suck at math
serg [7]

Answer:

Answer is ...Obtuse

Step-by-step explanation:

\frac{m

\frac{5x + 4}{2}  =  \frac{3}{2} x + 21

\frac{5x + 4}{2}  =  \frac{3x + 42}{2}

5x + 4 = 3x + 42

5x -  3x = 42 - 4

2x = 38

x = 19

substituting \: x = 19  \: \:in \:  \:  \:  \:  \:  \:  \: \\ m

We get,

m<ABC =

(5 \times 19) + 4 = 99

Hence <ABC is obtuse
