Kayla and Matt each improved their yards by planting grass sod and ornamental grass. They bought their supplies from the same store. Kayla spent $47 on 6 ft² of grass sod and 7 bunches of
ornamental grass. Matt spent $17 on 6 ft² of grass sod and 1 bunch of ornamental grass. What is
the cost of one ft² of grass sod and the cost of one bunch of ornamental grass?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
