The first one you have 
=
. To solve this you would multiply both sides by 3.
=x
Then simplify by dividing the numerator and denominator by 3.
=x (or in a mixed fraction 1
)
The second one you have 
=
. To solve this you would multiply both sides by x.
x=3
Now you would divide both sides by .
x=
You now then multiply 3 by 24 and then divide by 7.
x= (in a mixed fraction would be 10
)
Answer:
8421
Step-by-step explanation:
8050 < abcd < 8500
We must have a = 8, so the number is 8bcd.
The value of a is 20 times the value of b, or a= 2b.
a = 8, so b = 4.
The value of b is 20 times the value of c, or b = 2c.
b = 4, so c = 2.
The value of c is 20 times the value of d, or c = 2d.
c = 2, so d = 1.
The secret number is 8421.
Answer:
Step-by-step explanation:
The line that passes through the two points (6, -23) and (11, r) has a slope of 4.
We want to determine the missing value of r.
We can use the slope formula:
Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:
Simplify and evaluate:
Multiply both sides by 5:
Therefore:
