2t+3n=9 2(2)+3n=9
+5t-3n=5 (the 3n cancel out) 4+3n=9
7t=14 3n=5
t=2 n=5/3 or 1.67

Answer:
1st number: 22
2nd number: 16
3rd number: 64
Step-by-step explanation:
x + y + z = 102
x = 6 + y
z = 4y
plug that in!
(6 + y) + y + (4y) = 102
get rid of the parenthesis (I added them so you could see what I was replacing) and add like terms.
6 + 6y = 102
move 6 to the other side.
6y = 96
y = 16
now that you know one number, you can solve the equations for the rest!
x = 6 + (16)
z = 4(16)
__________________________________________________________
x = 22
y = 16
z = 64
Answer:
70 x 12 1/2 = 875.
Step-by-step explanation:
Step 1.) When you multiply fractions, you put whole numbers over one.
Step 2.) Then, you change whole numbers with fractions, to improper fractions.
Step 1.)
70/1 x 12 1/2
Step 2.)
70/1 x 25 / 2.
And then we solve!
70 x 25 = 1750
1 x 2 = 2.
1750 divided by 2 = 875.
Hope this helps!!
