Twice the tens digit of a two-digit number, increased by the units digit, is 19. If the digits are reversed, the new number is 45 less than the original number. Find the original number. Choose the correct system of equations needed to solve this problem. Assume t=tens digit, u=units digit

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
