Answer: t+20 = 60
Step-by-step explanation:
Answer: z = 3
Step-by-step explanation: To solve this equation for <em>z</em>, we can first combine our like terms on the left side of the equation. Since 12 and 7 both have <em>z</em> after their coefficient, we can subtract 12z - 7z to get 5z.
Now we have 5z - 2 = 13.
To solve from here, we add 2 to the left side of the equation in order to isolate 5z. If we add 2 to the left side, we must also add 2 to the right side. On the left side, the -2 and +2 cancel out. On the right, 13 + 2 simplifies to 15.
Now we have 5z = 15.
Solving from here, we divide both sides of the equation by 5 to get <em>z</em> alone. On the left side, the 5's cancel out and we are simply left with <em>z</em>. On the right side, 15 divided by 5 simplifies to 3 so we have z = 3.
28 students....ratio of boys to girls is 2 to 5...added = 7
2/7(28) = 56/7 = 8 boys
5/7(28) = 140/7 = 20 girls
so right now, there is 8 boys and 20 girls (8/20 = 2/5)
so lets add 2 boys...making it 30 students
10 boys and 20 girls = 10/20 = 1/2 or 1 to 2
answer is : u have to add 2 boys to get a ratio of boys to girls = to 1:2
