By working really hard. study each night for atleat 1 hour.
im in year 8 and have just reachex a level 7B
A+5=-5a+5 A=-5a+5-5 (bring one of the 5 over)(not necessary) A=-5a (if big and small letters are the same, A=a=0; if not, when A=35,a=-7)
The factorization of 5a^2 + 24a - 5 is (5a - 1)(a + 5).
Oh, come on! 6a - 5a = a, 7 - 5 = 2
-59
5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1
A+5=-5a+5 A=-5a+5-5 (bring one of the 5 over)(not necessary) A=-5a (if big and small letters are the same, A=a=0; if not, when A=35,a=-7)
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
The factorization of 5a^2 + 24a - 5 is (5a - 1)(a + 5).
5a x a = 5a2
Factor 5a-15 Factor out the 5; 5(a-3)
5a^2 - 5a - 60 ---- 5(a2 + a - 12)
5a+5=6a-7
The answer depends upon what the "x" here means. x is commonly used in algebra to denote a variable. However "x" is also a symbol used to mean multiplication. If the first then 5xa means 5 multiplied by x multiplied by a. If the second then 5xa means 5 multiplied by a. This is usually written simply as 5a.
Divide 5a and 180 by 5. a = 36
It is the 5 in 5a+2
-59
Oh, come on! 6a - 5a = a, 7 - 5 = 2
