Anumber is increased by 3.5 and a result is -4.3 find the number -7.8 -7.4 -7.1 -1.2

let "a number" = "x"

note that increased = +

x + 3.5 = -4.3

solve for x. note the equal sign. what you do to one side, you do to the other. subtract 3.5 from both sides

x + 3.5 (-3.5) = -4.3 (-3.5)

x = -4.3 - 3.5

x = -7.8

-7.8 is your answer for x

~rise above the ordinary

-7.8

step-by-step explanation:

3.5 + -7.8 = -4.3

3.5 + -7.4 = -3.9

3.5 + -7.1 = -3.6

3.5 + -1.2 = 2.3

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.
