Answer:
0
Step-by-step explanation:
The points on a number line are called coordinates. The zero point is called the origin. The numbers to the right of the origin are positive numbers; the numbers to the left of the origin are negative numbers.
Assume E represents the cost of an egg and T represents the cost of one piece of toast.
We can construct two equations :
2E + T = $3.00 - - - - - (a)
E + T = $1.80 - - - - - (b)
Subtract equation b from a:
E = $1.20 (The price of one egg)
To find out the price of one piece of toast, replace the price of one egg in equation b:
T = $1.80 - $1.20 = $0.60 (The price of one piece of toast)

Answer:
Yes
Step-by-step explanation:
3.5 [4d - 2*1.5] = 3.5*4d - 3.5*2*1.5
= 14d - 10.5
2*[7d - 5*1.05] = 2*7d - 2*5*1.05
= 14d - 10.5
When we are simplifying both the expression using distributive property, we get the same expression at the end.
1. 84 = 1 x 84
2. 84 = 2 x 42
3. 84 = 3 x 28
4. 84 = 4 x 21
5. 84 = 6 x 14
6. 85 = 7 x 12
Hope this helps!
P-6 because you subtract the variable from the 6
