<span>After you solve a system of linear equations, you will get an ordered pair (x,y). Replace x with whatever number you obtained for x, and replace y with whatever number you obtained for y. If both your equations are true upon simplifying, you know it is correct.</span>
Answer:
- A → B: 1/3
- correct
- A → B: 2/5
Step-by-step explanation:
It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.
- A → B = 1/3; B → A = 3
- A → B = 2; B → A = 1/2
- A → B = 2/5; B → A = 5/2

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.
- B : A = 1 : 3
- A : B = 1 : 2
- B : A = 2 : 5
Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.
Answer:
136
Step-by-step explanation:
7*5=35
35+35=70
1/2*6*4=12
12+12=24
6*7=42
70+42+24=136
sorry if it is wrong.
Answer:
5
Step-by-step explanation:
Given: 5^3– 10^2 = X(8 – 2) + 2X – 3X
Solving the equation to find the value of x.
⇒ 
Using the distributive property of multiplication, multiplying x with 8 and -2
⇒
cancelling out -2x and 2x
⇒ 
⇒ 
Multiplying both side by 5
⇒ x= 
∴ x= 5
Hence, the value of unknown is 5.
