The number of boys in ninth grade is 12 less than twice the number of girls There are 51 students in ninth grade How many are girls?
Let x= number of girls
2x-12 = number of boys
x+(2x-12) = 51
3x-12 = 51
3x = 63
x = 21
CHECK
21+2(21)-12 = 51
21+42-12 = 51
21+30 = 51
There are 21 girls in ninth grade
What else can I help you with?
If a ninth of a number is 1543 what is the number?
13,887To find this just times 1543 by 9.
What is three to the negative ninth power?
Three to the negetive ninth power is 0.037
A number raised to the ninth power?
Oh honey, when you raise a number to the ninth power, you're basically multiplying that number by itself eight more times. It's like saying "I'm not just strong, I'm strong to the power of nine!" So, if you have 2^9, you're looking at a whopping 512. Math can be sassy too, you know!
What number could be 7 and 9 over 10 on a number line?
The number would be 7.9 on a number line. What you can do to find this number is go to the spot on the number line that says 7 and 8. Cut the number line between 7 and 8 into 10 pieces. Then count to the ninth peice and this is 7.9
What grade level learns algebra 1?
Where I live in Florida, a gifted honors class would learn in 8th grade, a regular honors class would learn in 8th grade(like myself), and normally you would learn Algebra 1 in 9th grade. I live in Maine, but I just moved from New Jersey. In both places, normally, kids would do Algebra 1 in 8th grade. If they aren't too good at math, then they would do it in 9th grade, and if they are advanced, then they would do it in 7th grade. Where I live in Cali, most of our students in my school in 8th grade would learn algebra 1 and others will learn pre-algebra. This year in Cali, every 8th grade levels from other schools would take Algebra 1. So it used to be 9th graders who would learn Algebra 1. Our percentage results were pretty high compared to other schools who took it. Where i live in Pennsylvania, we do algebra 1 in 8th grade A class, pre-algebra in 8th B class, Algebra 1 in 8th Independent class (which is like the highest you can get into), finish Algebra 1 in 8th A class, and finish pre-algebra in 8th B class. I was in the 7th grade A class and the 8th grade Independent class, cause I was a freakin' genius and got straight A's every trimester of every grade. I go to a private school, and most private school classes are naturally ahead of the public school systems'. In 7th grade, I took Pre-Algebra and now as I'm in eighth grade I take Algebra 1 and 2 and have a test every other week. But usually, as said before, Algebra 1 is normally taken by ninth grade students in public school =) The order in middle school through high school... that i know of in Maryland... is math 6, math 7, pre-alebra, algebra 1, honers geometry, algebra 2, and so on. You can also be advanced, when I was in 8th grade, I took Algebra 1, and my friend took honers geometry, but usually you learn Algebra is learned in 9th grade. at my school everyone does pre-algebra in 7th grade algebra 1 in 8th geometry in 9th and algebra 2 in 10th I'm taking algebra 1 right now, and I'm in the 8th grade. i think I'm in an advanced math class tho, and at this place, most people take it 9th grade.

The number of boys in ninth grade is 12 less than twice the number of girlsthere are 51 astudents in ninth grade how many are girls?
If the number of boys in ninth grade is 12 less than twice the number of girls there are 51 astudents in ninth grade then the number of girls is 21
The number of boys in the ninth grade is 12 less than twice the number of girls there are 51 students in the ninth grade how many are girls?
Let's say the number of girls is x and the number of boys is y. Then the information we have is: There are 51 students, so: x + y = 51 And 12 less than twice the number of girls are boys, so: y = 2x-12 Replace y in the first equation with the second and you get: x + (2x-12) = 51 3x = 63 x = 21 So there are 21 girls in the ninth grade. To check back, that means there should be 30 boys, and that is indeed 12 less than twice the number of girls.

The number of boys in ninth grade is 12 less than twice the number of girls. There are 51 students in ninth grade. How many are girls?
Let's lay out the known information in equations, where B is the number of boys and G is the number of girls. Then we express the number B in terms of G, which is twice as much less 12, or (2G-12) B + G = 51 , and B = 2G - 12 Now, replace the B in the first equation with its value from the second equation (2G - 12) + G = 51 Remove the brackets 2G - 12 + G = 51 Add 12 to both sides 2G + G = 51 + 12 3G = 63 Divide both sides by 3 G = 21 Now, to check if we're right, Replace G in the first equation B + 21 = 51 B = 30 If that's right then 30 = 2(21) - 12 30 = 42 - 12 And it is, so we know that there are 21 girls and 30 boys in ninth grade.
