Answer:
<u>325 Hamburgers.</u>
Step-by-step explanation:
This may seem complicated at first due to us not knowing how much either hamburgers or cheeseburgers were sold, but we can easily set up an equation with variables and solve this using the numbers provided.
x = # of hamburgers sold.
x + 61 = # of cheeseburgers sold.
1) x + x + 61 = 711 (set both burgers equal to the total sold)
2) 2x + 61 = 711 (added common variables together)
3) 2x = 650 (negated the +61, subtracted it from both sides)
4) x = 325 (divided both sides by 2)
5) 711 - 325 = 386 (subtracted the x from the total number of burgers sold, to recieve the amount of cheeseburgers' tickets.
Thus,
Since there were fewer hamburgers sold, the smaller number (325) is the correct answer.
(Final Answer)
Cheeseburgers sold: 386
Hamburgers sold: 325
Total sold: 711
1) You have vertical angles here. This means the big and small triangles are similar, meaning the ratio of corresponding sides of the two triangles are equal.
In this case, 32cm corresponds to 4cm and 40cm corresponds to x. To find x, set up the ratio as follows: 4/32 = x/40.
4/32 can be reduce to 1/8. Multiply each side by 40 to isolate x. you get 1/8 * 40
This yields x = 5 cm
2) set up a proportion, similar to the first question.
(x + 4)/8 = (2x + 1)/12
12(x + 4) = 8(2x + 1)
12x + 48 = 16x + 8
40 = 4x
x = 10
the length of BC is (x + 4) + (2x + 1) = 3x + 5
this means BC = 35
Answer:
19
Step-by-step explanation:
This is because since 19 is the larger odd number, 17 must be the smaller one, and 19 times 17 is 323.
Hope this helps! :)
It's 9.48 but you should just use a calculator.
