Andy and sam are saving money to go on their senior trip. the amount of money that andy will have at the end of each week, w, can be expressed at a(w) = 20w + 300. the amount of money that sam will have at the end of each week, w, can be expressed at s(w) = 15w + 400. they have decided to combine their savings accounts. write a function that expresses the total amount, t(w) they have in their savings account at the end of each week. a) t(w) = 5w - 100 b) t(w) = 35w + 700 c) t(w) = -5w + 100 d) t(w) = 300w2 + 12500w + 12

B. T(w) = 35w + 700

Step-by-step explanation:

Basically what you will do is combine 20w + 15w and get 35w. Then you do the same with 300 + 400 which gives the answer T(w)= 35w+700.

A(w)=20w+300

S(w)=15w+400

20w  + 15w  = 35w

300 +  400 = 700

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
