Contacting in the future, he still needs the answer
LENGEND SAS HE IS STILL WAITING FOE THAT ANSWERRR.......
so give it to him all ready...
Wow this is sad...he'll never get his answer will he? XD
wtf
To find the value of x that makes each pair of ratios equivalent, we need to set up a proportion and solve for x.
Let's go through each question one by one:
1. x:4 and 45:20
To make the ratios equivalent, we need to find a value of x such that x:4 is the same as 45:20.
Setting up the proportion:
x/4 = 45/20
Cross-multiplying:
20x = 180
Dividing both sides by 20:
x = 9
So the value of x that makes the ratios equivalent is 9.
Answer: B. 9
2. 21 to x and 7 to 10
To make the ratios equivalent, we need to find a value of x such that 21 to x is the same as 7 to 10.
Setting up the proportion:
21/x = 7/10
Cross-multiplying:
10 * 21 = 7 * x
Dividing both sides by 7:
x = 30
So the value of x that makes the ratios equivalent is 30.
Answer: B. 30
3. x to 50 and 16 to 25
To make the ratios equivalent, we need to find a value of x such that x to 50 is the same as 16 to 25.
Setting up the proportion:
x/50 = 16/25
Cross-multiplying:
25x = 800
Dividing both sides by 25:
x = 32
So the value of x that makes the ratios equivalent is 32.
Answer: A. 32
4. 6 to 8 and 18 to x
To make the ratios equivalent, we need to find a value of x such that 6 to 8 is the same as 18 to x.
Setting up the proportion:
6/8 = 18/x
Cross-multiplying:
6x = 8 * 18
Dividing both sides by 6:
x = 24
So the value of x that makes the ratios equivalent is 24.
Answer: C. 24
5. 9/36 and x/4
To make the ratios equivalent, we need to find a value of x such that 9/36 is the same as x/4.
Setting up the proportion:
9/36 = x/4
Cross-multiplying:
9 * 4 = 36 * x
Dividing both sides by 36:
x = 1
So the value of x that makes the ratios equivalent is 1.
Answer: A. 1
6. 42/22 and 21/x
To make the ratios equivalent, we need to find a value of x such that 42/22 is the same as 21/x.
Setting up the proportion:
42/22 = 21/x
Cross-multiplying:
42x = 22 * 21
Dividing both sides by 42:
x = 11
So the value of x that makes the ratios equivalent is 11.
Answer: B. 11
7. x/7 and 5/1
To make the ratios equivalent, we need to find a value of x such that x/7 is the same as 5/1.
Setting up the proportion:
x/7 = 5/1
Cross-multiplying:
x = 35
So the value of x that makes the ratios equivalent is 35.
Answer: A. 35
8. 20/X and 4/8
To make the ratios equivalent, we need to find a value of x such that 20/X is the same as 4/8.
Setting up the proportion:
20/X = 4/8
Cross-multiplying:
4X = 20 * 8
Dividing both sides by 4:
X = 40
So the value of X that makes the ratios equivalent is 40.
Answer: B. 40
