Abigail has $30.00 to buy groceries. She needs to buy some apples, some bananas, and 3 pounds of potatoes. Fuji apples are $1.97 a pound, Bananas are $.36 each, and potatoes are $2.99 for a 3 pound bag. If a represents the number of pounds of apples Abigail buys and B represents the number of bananas she buys, which expression represents the amount of change she receives after her purchase 30.00-a-b
1.79a+0.36b+2.99
30.00-(1.79a+0.36b+2.99)
30.00+(1.79a+0.36b+2.99)

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
