Answer:
$41.16
Step-by-step explanation:
Length of bricks required = 35 feet, length of brick sold = 10 inches, cost of 10 inches brick = $0.98 per brick
Total number of brick required to build the back yard = Length of bricks required ÷ Length of brick sold
1 ft = 12 inches
Number of brick required = (35 * 12) ÷ 10
Number of bricks required = 42 bricks
Cost of brick required = Per length cost of brick * Number of bricks required
Cost of brick required = 0.98 * 42
Cost of brick required = $41.16
Ms. Fontanges would spend $41.16 on the purchase of bricks
Answer:
1. A. (3,-2)
2. D. (-4,3)
3. (4,-2)
4. B. 3 cars
5. B. -10x7y2
Step-by-Step Explanation:
1. Graph the problem next time and to solve it, you just write the point where the intersect.
2. Write the second equation into the first one by substituting the y with the second equation: -3x-3(-5x-17)=3
3. Tbh its easier to just graph this one too and find the intersect point.
4. After reading the problem you should come up with the equations 5x+45y=195 and x+y=7 with x representing the number of cars and y representing the number of buses. All you have to do is substitute them into each other like in problem 2.
5. Multiply 12 and -5/6, then multiply the variables x^4 with x^3 y^2. All you have to do is add the exponent numbers together.
