Answer:
15:10
Step-by-step explanation:
Method 1: 5 lots of 3:2 →5 × (3:2) = (5×3) : (5×2) = 15:10
Method 2: 3/2 × 1 → 3/2 ×5/5 = 3×5 2×5= 15:10
boys: 15
girls: 10
The correct answer for this very hard equation would happen to be 12 because 18+12 happens to equal 30 and 42-30 just so happens to equal 12
Answer:
(i think) 1.5
Step-by-step explanation:
If you replace y with the equation y=2x-3, you get 5(2x - 3)
if you distribute this, it equals 10x - 15
combining like terms 10x + 10x - 15=15 will turn into 20x - 15 = 15
if you add 15 to both sides, -15 will cancel and 15 will turn into 30
20x = 30
divide both sides by 20 which will lead to x=1.5
Answer:
9x^2+22x-2
Step-by-step explanation:
f(g(x))=(3x+1)^2+2(3x+1)-4
=9x^2+16x+6x+2-4
=9x^2+22x-2
to find the soultion of mentioned question you have to put the value of g(x) into f(x) and then solve it like normal ...
Answer:
1.25p
Step-by-step explanation:
p = amount raised last year
amount raised this year = p +(25% of p)
=1 p+0.25p
