450 chairs total
20 chairs per row
15 rows already set up
15×20=300
300 chairs already up
450-300=150
150 chairs left to set up
PEMDAS
the first thing is multiply or distribute
a(b+c)=ab+ac
8(t+2)=8t+16
-3(t-4)=-3t+12
6(t-7)=6t-42
the equation comes out to
8t+16-3t+12=6t-42+8
add like terms
5t+28=6t-34
subtract 5t from both sides
28=t-34
add 34 to both sides
62=t
Answer:
= $45
Step-by-step explanation:
$2.25 = 1 pound
$2.25 x 5 = 5 pounds
$11.25 = 5 pounds
$11.25 x 4 = 4 bags
$45 = 4 bags

The answer this question was easy to solve so here it is -x+7
Answer:
(2, 5 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 1 → (1)
2x + 4y = 24 → (2)
Substitute y = 3x - 1 into (2)
2x + 4(3x - 1) = 24 ← distribute and simplify left side
2x + 12x - 4 = 24
14x - 4 = 24 ( add 4 to both sides )
14x = 28 ( divide both sides by 14 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 3(2) - 1 = 6 - 1 = 5
solution is (2, 5 )
