Answer:
cost of nachos = $3.45
Cost of tacos = $1.5
Step-by-step explanation:
Let
x = cost of nachos
y = cost of tacos
11x + 18y = 64.95 (1)
6x + 15y = 43.20 (2)
Multiply (1) by 6 and (2) by 11 to eliminate x
66x + 108y = 389.70
66x + 165y = 475.20
Subtract to eliminate x
165y - 108y = 475.20 - 389.70
57y = 85.50
y = 85.50/57
y = 1.5
Substitute y = 1.5 to find x
11x + 18y = 64.95 (1)
11x + 18(1.5) = 64.95
11x + 27 = 64.95
11x = 64.95 - 27
11x = 37.95
x = 37.95/11
x = 3.45
cost of nachos = $3.45
Cost of tacos = $1.5
One inch equals 25 miles
Two inches equals fifty miles
Three inches equals seventy five miles
Four inches equals one hundred miles
.1 inches equals 2.5 miles
.4 inches equals 10 miles
Seventy five miles plus ten miles equals eighty five miles.
Answer:
Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials.
Step-by-step explanation:
How do I combine like terms?
1. Step 2: Combine the coefficients.
2. 5h + 11g + 1h - 8g.
3. (5 + 1)h + (11 - 8)g.
4. 6h + 3g.
5. Step 1: Organize your like terms.
6. 5x + 8x + 10x2 - 7x2 - 4x.
7. Step 2: Combine the coefficients. (5 + 8 - 4)x + (10 - 7)x2 9x + 3x2
