Answer:
The cost of soft pretzel is $1.25
Step-by-step explanation:
Let $x be the price of one slice of pizza and $y be the price of one soft pretzel.
1. 9 slices of pizza cost $9x and 5 soft pretzels cost $5y. Together they cost $33.25, then
9x+5y=33.25.
2. 4 slices of pizza cost $4x and 6 soft pretzels cost $6y. Together they cost $19.50, then
4x+6y=19.50.
3. Solve the system of two equations:
Multiplythe first equation by 4, the second equation by 9 and subtract them:
Then
Answer:
Step-by-step explanation:
3x + 6 = 8 + 3x - 2
3x + 6 = 3x + 6
Bringing like terms on one side
3x - 3x = 6 - 6
0 = 0
Answer:
1800 cm
Step-by-step explanation:
Answer:
f(x)=12x-5
Step-by-step explanation:
-5 is the y-intercept since f(1)=0
the difference from -5 and 7 (7-(-5) or 7+5) is 12 and 12/1 equals 12
The width of the cooling tower at the base of the structure will be A. 36 meters.
<h3>How to calculate the width?</h3>
From the information given, the towers walls are modeled by x²/324 - (y² - 90)²/1600.
Therefore, the width of the cooling tower at the base of the structure will be:
= 2 × ✓324
= 2 × 18
= 36
In conclusion, the width is 36 meters.
