Answer:
7x - 2
Step-by-step explanation:
let x be the number of bags of chips, then
3x is the number of bags of pretzels ← 3 times the number of bags of chips
3x - 2 is the number of bags of nachos ← 2 less than bags of pretzels
total snacks bought = x + 3x + 3x - 2 = 7x - 2
Answer:
0.58x3=1.74
Step-by-step explanation:
first, you line up the numbers, easiest with the 0.58 on top. then, you multiply 3x8, which is 24. you put the four in the hundredths place, and carry the two. then, you multiply 3x5 and get 15, and add the two, making it 17. you put the seven in the tenths place, and carry the one the ones place. then you will multiply three by zero and get zero. finally, you add the one, and your answer is 1.74.
Answer:
A) 7x^2-7x+15
Step-by-step explanation:
f(x) = 4x2 - 5x + 7,
g(x) = 3x2 - 2x + 8
f(x) +g(x) =
4x^2 - 5x + 7 + 3x^2 - 2x + 8=
7x^2-7x+15
Answer:
4
