Alexis raises 75.23 for charity. sue raises 3 times as much as alexia. manuel raises 85.89.how much money do the three raise for charity in all? show work

the amount of money raised by the three for charity in all is 386.81

Step-by-step explanation:

Alexis raises 75.23 for charity.

Sue raises 3 times as much as Alexis. This means that the total amount of money raised by Sue is 3 × 75.23= 225.69

The amount of money that Manuel raises is 85.89.

The amount of money raised by all of them(Alexis, Sue and Manuel) would be sum of the amount of money raised by Alexis + the amount of money raised by Sue +

the amount of money raised by Manuel. This becomes

75.23 + 225.69 + 85.89 = 386.81

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2
