3 (3 + x) = 5x - 25
9 + 3x = 5x - 25
Add 25 to each side
34 + 3x = 5x
Subtract 3x from each side
34 = 2x
Divide each side by 2
17 = x

Answer:
a) 44g
b)4620g
Step-by-step explanation:
a)
25 chocolates = 1100g
1 chocolate = 1100/25
answer: 44g
b)
25 chocolates = 1100g
1 chocolate = 1100/25
100 chocolates = 1100/25×105
answer: 4620g
So subtract 9 on both sides
10n=80
Divide by 10 on both sides
n=8
Answer:
<em><u>(d+1)(d+4) if i can get brainliest that would be great</u></em>
Step-by-step explanation:
The middle number is 5 and the last number is 4.
Factoring means we want something like
(d+_)(d+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 5
Multiply together to get 4
Can you think of the two numbers?
Try 1 and 4:
1+4 = 5
1*4 = 4
Fill in the blanks in
(d+_)(d+_)
with 1 and 4 to get...
(d+1)(d+4)
