The equation on number 3 is showing that Henry hikes 0.5 miles per hour, with x = number of hours. The graph shows that Clark hikes 15 miles in 10 hours, or 1.5 miles per hour. Clark is faster because of the reasons listed above.

Problem 4 is strange because it has a different value from x = 1 to x = 4 than it does for x = 5 and above, but my best guess would be a piecewise function:
If x < or equal to 4, 15x. If x > 4, 10 × (x - 4) + 60.

Problem 5 is much simpler: because x goes up 16 every time y goes up 6, 6/16 × x or (6/16)x.

At the parents evening the ratio of mums to dads was 3:2. Out of 500 appointments how many were with mums?
guajiro [1.7K]

Answer:

300

Step-by-step explanation:

Sum the parts of the ratio : 3 + 2 = 5 parts

Divide the number of appointments by 5 to find the value of one part of the ratio, that is

\frac{500}{5} = 100 ← value of 1 part of the ratio

The mums consisted of 3 parts, hence

3 × 100 = 300 ← appointments with mums

The sum of an integer and 6 times the next consecutive odd integer is 61. Find the
vfiekz [6]

If the sum of an integer and 6 times the next consecutive integer is 61, the the value of lesser integer is 7

Consider the first odd integer as x

Then the next consecutive odd integer = x+2

The 6 times the second integer=  6(x+2)

= 6x+12

Sum of an integer and 6 times the next consecutive odd integer is 61

Then the equation will be

x + 6x+12 = 61

Add the like terms in the equation

(1+6)x + 12 = 61

7x +12 = 61

Move 12 to the right hand side of the equation

7x = 61-12

7x = 49

x = 49/7

x = 7

The second number is

x+2 = 7+2

= 9

Hence, if the sum of an integer and 6 times the next consecutive integer is 61, the the value of lesser integer is 7
