Ralph Cohen, in his 1964 critical history of Thomson's The Seasons, argued nearly half a century ago that illustrations are criticism of the works they illustrate. More recently, critics have fruitfully explored illustrations of the works of Defoe and Sterne. In her study of graphic design and the novel, Janine Barchas has explained the function of illustrations as interpretive guides." Barchas mainly discusses frontispieces, but her point applies to other kinds of illustrations. In the case of Tobias Smollett, illustrations not only indicate what illustrators thought of the novels, but may also reveal how those novels were received by readers. The number and diversity of the images are especially valuable because, as Fred W. Boege long ago demonstrated, we know relatively little about how eighteenth-century readers conceived of Smollett as a novelist. Our understanding of Smollett's reception has improved since Boege's time, but some difficulties in knowing what readers thought of Smollett remain, because recorded responses are scanty. Roderick Random, for instance, did not receive any reviews, since it was published before reviewing contemporary fiction became widespread. And reviews of the other novels consist mainly of large excerpts from the work itself with a few general remarks on how well the characters are conceived. Nor do the few responses we have provide a consistent picture of how Smollett was read. The illustrations, therefore, give us alternative perspectives that can only enrich our understanding of Smollett's reception.
Machines G and H cut sheets of plastic into pieces that are used in car manufacturing. Working alone at its constant rate, machine G cuts 10 sheets of plastic in 8 minutes. Working alone at its constant rate, machine H cuts 20 sheets of plastic in 24 minutes. How many minutes does it take machines G and H, working simultaneously at their respective constant rates, to cut a total of 30 sheets of plastic?
For each of the three years 2018, 2019, and 2020, the value of a car at the end of the year was x percent less than its value at the end of the preceding year.

The early-nineteenth-century British economy did not experience a rapid and wholesale "industrial revolution," as scholars once claimed. Nevertheless, the more gradual and uneven picture that has emerged at the aggregate level should not disguise the fact that in some regions and industries dramatic discontinuities occurred, creating an economic configuration (and a cultural response) that became very different very quickly. Perhaps paradoxically, the recent scholarly emphasis on gradualism has placed focus on the 1830s as a decade of critical change, when economic development accelerated significantly and a recognizable "industrial" economy first became visible, with many industries and occupations rapidly evolving. Factories and machines did not become ubiquitous, but they became dominant images of the age and a powerful motor for the development of new social identities.
In the xy-plane, the point $$(t, t-1)$$ lies on the line with equation $$y=-\frac{1}{2} x +\frac{1}{3}$$. What is the value of $$t$$?

Give your answer as a fraction.

Quantity A

$$\frac{1}{2}(x+y)$$

Quantity B

$$\frac{1}{2}x + y$$
