at a country concert,the ratio of number of the Boys to the number of girls is 2:7 if there are 250 more girls than boys how man
sergey [27]

Answer:

100

Step-by-step explanation:

Ratio is a fraction, so ratio of boys to girls would be written as [let boys be "b" and girls be "g"]:

\frac{b}{g}=\frac{2}{7}

Also, there are 250 more girls than boys, so we can write:

g = 250 + b

Lets substitute this into "g" of the ratio we wrote and cross mulitply and solve for b:

\frac{b}{g}=\frac{2}{7}\\\frac{b}{250+b}=\frac{2}{7}\\7b=2(250+b)\\7b=500+2b\\5b=500\\b=\frac{500}{5}=100

The number of boys = 100

8)Solve and rewrite using the distributive property __(__+__) = 12 +24​
Alla [95]

The distributive property will give answer 2 ( 6 + 12 ) = 12 + 24 .

The distributive law of multiplication over basic arithmetic such as addition and subtraction is known as distributive property .

According to this property , multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the no . and then adding the products together .

In other words, according to the distributive property, an expression of the form A ( B + C ) can be solved as A ( B + C ) = AB + AC.

2 ( 6 + 12 ) = 12 + 24 .

Hence , the distributive property will give answer 2 ( 6 + 12 ) = 12 + 24 .
