The speed of ben is 6 m/s greater than the speed of emma. ben rides 100m when emma rides 76 m. what is the speed of ben, x?

The speed of Ben, x= 25m/s

Step-by-step explanation:

Key concept: Ben rides 100 m and Emma rides 76 m in the same time.

Step 1: Suppose, the speed of Ben is x m/s.

Since the speed of Ben is 6 m/s greater than the speed of Emma,  

So the speed of Emma would be (x-6) m/s.

Step 2: Calculate time for each and equate them as follow:

100/x= 76/(x-6)

After cross multiplying, we get:

100(x-6)=76x

100x-76x=600

24x=600

x= 25

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
