Answer:
20
Step-by-step explanation:
Evaluate 3 x^2 - 4 x where x = -2:
3 x^2 - 4 x = 3×(-2)^2 - -2×4
Hint: | Evaluate (-2)^2.
(-2)^2 = 4:
3×4 - 4 (-2)
Hint: | Multiply 3 and 4 together.
3×4 = 12:
12 - 4 (-2)
Hint: | Multiply -4 and -2 together.
-4 (-2) = 8:
8 + 12
Hint: | Evaluate 12 + 8 using long addition.
| 1 |
| 1 | 2
+ | | 8
| 2 | 0:
Answer: 20
The answer is 1/8 because if you divide both numbers by 5 it would be simplified into 1/
Answer:
Money Ivan gets extra = 120 - 30 (or 3x) = 90
Step-by-step explanation:
Ivan = 4x
Tanya = 1x
Total = 150
4x + x = 150
5x = 150 ; x = 150 / 5 = 30
Ivan = 4x = 120
Tanya = 1x = 30
Money Ivan gets extra = 120 - 30 (or 3x) = 90
Marcus shoes: 35.99(5.5%)= (about) $1.98(tax) so 35.99+1.98= 37.97
Tia shoes: 39.99(9%)= (about)3.60 (tax) so 39.99+3.60=43.59
However it’s 15% off so 43.59(15%)= 6.54 so 43.59-6.54= 37.05
The difference is 0.92
