ANSWER QUICK FOR BRANLIEST PLEASEEE The ration of boys to girls is 5:4. If there are 20 girls, how many boys are there?

25

Step-by-step explanation:

5 boys: 4 girls  = x boys: 20 girls

Multiple of 5 to get from 4 girls to 20 girls

use the same multiple for boys

5 boys x 5 = 25

If the ratio of the boys to girls is 5:4, and there are 45 students, then what is the number of boys and girls.

First, you would add 5 and 4, because that is the numbers in the ratio.

5+4=9

Then, you would do 45/9, and that would let you find out how many students is represented by each number in the ratio.

45/9=5

You would then multiply 5 to both, 5 and 4, to find out the number of boys to girls.

5(5:4)

25:20

There are 25 boys and 20 girls.

To check, 25+20 is equal to 45, the number of students in the class, and if you simplify 25:20, it simplifies to 5:4.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
