You divide by 5/13. Remember when dividing fractions you multiply by the reciprocal. 5/13 cancels on the left side, leaving t.
So here you have -9/(5/13), but we can put -9 as -9/1, then instead of dividing by 5/13, multiply by 13/5: 117/5. This evens out, when divided, to t=23.4
Four times fifteen plus twenty in parentheses
idk if its correct though <span />
Answer:
Step-by-step explanation:
x² = 19x + 12
⇔ x² - 19x - 12 = 0
Calculating the discriminant :
b² - 4ac = (-19)² - 4×1×(-12) = 409
The discriminant is positive ,then the equation has two solutions.
6 ft into meters would be 1.829, rounding to to nearest tenth would be 1.8
