We can setup an equation for this.
Boys to Girls = 2:7
Boys = x
Girls = 250+x
Setup the ratio
x:(250+x) = 2:7
x / (250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100
There are 100 boys at the concert
Answer: In picture below.
Step-by-step explanation:
Find the points on the line and then draw lines to them.
1. 36 = 6·6 and 42 = 6·7 have a common factor of 6.
... x⁴ and x² have a common factor of x²
The GCF is 6x².
The factorization is 36x⁴ -42x² = 6x²(6x² -7)
2. All coefficients are multiples of 4. All variable factors are multiples of x³.
The GCF is 4x³.
The factorization is 4x⁵ -8x⁴ -4x³ = 4x³(x² -2x -1)
3. The GCF of coefficients 6 and 15 is (15 mod 6) = 3, which is also a factor of the other coefficients. The lowest power of m, which is m² is also a factor of the other terms.
The GCF is 3m².
The factorization is 6m⁵ -15m⁴ -21m³ +27m² = 3m²(2m³ -5m² -7m +9)
She must by 60 tiles for the prices to be even. 24+0.79x=1.19x x=amount of tiles. you subtract 0.79x from both sides. you should get 24=0.4x. then you divide 0.4 from both sides. you should get 60=x
If the lines are perpendicular they would have a 90 degree angle. the diagonal line dissects this angle and is 47 degrees. to solve this you would do 90-47 which equals 43
