How do you add the fractions 4/9 + 13/18

7/6 or 1 1/6

Step-by-step explanation:

you have to make the denominator equivalent. since 13 cant be split evenly into two, you double 4/9. so 4 times 2 is 8 and 9 times 2 is 18. so it would be 8/18. then you add the numerators and simplify

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
