Answer:

y = 3

Step-by-step explanation:

$\rm 7y+y-2y=18$

$\rm 8y-2y=18$

$\rm 6y=18$

$\rm y = 18 \div 6$

$\rm \bold{y = 3}$

Apply the distributive property to factor out the greatest common factor. 35+50=35+50=?

a_sh-v [17]

Answer with explanation:

The given mathematical expression to solve : $35+50$

The prime factorization of each term can be written as follows :-

$35=5\times7$

$50=5\times5\times2$

We can see that the greatest common factor of both the terms = $5$

So we rewrite the given expression as :-

$5\times7+5\times10$

By using distributive property :-

$ab+ac=a(b+c)$ , we have

$=5(7+10)=5(17)=85$

There are 45 red tiles,25 blue tiles and 30 green tiles in a bag.

Mazyrski [523]

This is a question of probability.
Probability of picking any color= number of tiles with that color/total number of tiles
Total=45+25+30=100
P(red tile)=(45/100)x60=0.45x60=27
P(blue tile)=(25/100)x60=0.25x60=15
P(green tiles)=(30/100)x60=0.3x60=18

1( m² + 15m + 56) = (____) (m+8)<br>2 a² +5ab + 6b²=(a +2b (_____)<br><br>pastor po

Nutka1998 [239]

Step-by-step explanation:

${m}^{2} + 15m + 56 = ( \: \: \: \: \: )(m + 8) \\ solution \\ \: \: taking \: lhs \\ = {m}^{2} + 15m + 5 \\ = {m}^{2} + (7 + 8)m + 56 \\ \: \: \: \: = {m}^{2} + 8m + 7m + 56 \: \: \\ now \: taking \: common \: factor \\ m(m + 8) + 7(m + 8) \\ (m + 7)(m + 8) \\ now \\ {m}^{2} + 15m + 56 = (m + 7)(m + 8)$

${a}^{2} + 5ab + 6 {b}^{2} = ( a + 2b)( \: \: \: \: \: \: \: \: ) \\ solution \\ taking \: \: lhs \\ = {a}^{2} + 5ab + 6 {b}^{2} \\ = {a}^{2} + ( 3+ 2)ab + 6 {b}^{2} \\ = {a}^{2} + 3ab + 2ab + 6 {b}^{2} \\now \: taking \: common \: factor \\ a(a + 3b) + 2b(a + 3) \\ (a + 2b)(a + 3) \\ now \\ {a}^{2} + 5ab + 6 {b}^{2} = ( a + 2b)( a + 3) ans$
