Answer:
Where is the question?
Step-by-step explanation:
Answer:
- <u>3 </u><u>and</u><u> 17</u> are required integers
Step-by-step explanation:
- Let one integer be x
- And other integer be y
x = 4y + 5
xy = 51
<u>According to </u><u>question </u><u>:</u>
➞ (4y + 5)y = 51
➞ 4y² + 5y = 51
➞ 4y² + 5y - 51 = 0
➞ 4y² + 17y - 12y - 51 = 0
➞ y (4y + 17) - 3(4y + 17) = 0
➞ (y - 3)(4y - 17) = 0
➞ y - 3 = 0
➞ <u>y = 3</u>
Hence,
➞ <u>y = 3</u>
➞ x = 4y + 5
➞ x = 4 (3) + 5
➞ x = 12 + 5
➞<u> </u><u>x = 17</u>
∴ The required integers are <u>3 and 17</u>

Answer:
70 fries and 35 shakes
Step-by-step explanation:
ASB is selling In-N-Out as a fundraiser. Fries cost $2 and shakes cost $3. Students can only buy one item each. ASB wants to know which sells better but they lose track of what they sold. They know 105 students bought either fries or a shake. They count their money and it’s $245. How many fries (x) and shakes (y) did they sell?
f = fries
s = shakes
To solve this we need to make two equations. Those equations being: f+s = y and 2f+3s = y. Now we will plug in all the values. f + s = 105 and 2f + 3s = 245. Now we will subtract f from 105 to get s. this makes s =105-f. We can then plug this into the other equation making the other equation: 2f+ 3(105-f) = 245. Now we will simplify this to get: 2f + (315 -3f) = 245. When we simplify it further we get: 315-f = 245.Now we will subtract 315 from both sides to get: -f = -70. now divide both sides by -1 and we get f = 70. Now we can plug that into the f+ s = y equation. 70 + s = 105. Subtract 70 from both sides and we have s. S = 35
