<span>RS= 8y + 4, ST = 4y + 8, and RT = 36
RS + ST = RT
</span>8y + 4 + 4y + 8 = 36
12y + 12 = 36
12y = 24
y = 2
answer
y = 2 (first choice)
The correct answer is C. Let’s break this down with the distributive property.
5(6x+6)
30x+30
5(9-x)
45-5x
Now add and subtract like terms.
30x-5x=25x
30+45=75
Put the remaining numbers together.
25x+75 and there you go.
Answer:
-85
Explanation:
Given the mathematical expression:

First, we recall the product of signs.

So, first, we open the bracket:

We then simplify:

The result is -85.
Answer:

Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:

--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount

Substitute
for A in


Substitute
for F in 

The total amount is calculated by adding the earnings of Alice, her friend and you



<em>Hence, the total earnings is 5d - 2</em>
One way:
585-320=265 (Rounding to the nearest 5)
590-320=270 (Rounding to the nearest 10)
600- 300= 300 (Rounding to the nearest 100)
