Answer:

y = 3

Step-by-step explanation:

The figures are similar so the ratios of corresponding sides are equal, that is

\frac{UR}{DA} = \frac{TS}{CB} , substitute values

\frac{4}{2} = \frac{3y+5}{7} ( cross- multiply )

2(3y + 5) = 28 ( divide both sides by 2 )

3y + 5 = 14 ( subtract 5 from both sides )

3y = 9 ( divide both sides by 3 )

y = 3

Daryl has a total of 160 National Football League (NFL) trading cards from both the American Football Conference (AFC) and the N
Svet_ta [14]

Answer:

B

Step-by-step explanation:

Since A represents the number of AFC cars and N represents the number of NFC cards, and that Daryl has 160 total cards, then A+N = 160, the total number of cards. Furthermore, the number of AFC cards Daryl has is 8 more than 3 times the number of NFC cards, so A would be equal to 8 + 3N, or A = 3N + 8. The only system of equations with both of these correct equations is B.

90 hazelnuts have a mass of 125 g. Hazelnuts have 630 calories per 100 g. work out the number of calories per hazelnut
jenyasd209 [6]

90 hazelnuts = 125g

Therefore, the mass of one hazelnut is this...

90 / 90 = 125 / 90

1 hazelnut = 25/18 grams


630 calories = 100 grams

100 divided by 25/18 = 72

Therefore...

630 / 72 = 1 hazelnut

AND THE ANSWER IS

8.75 calories = 1 hazelnut
