Answer:

5+6+7+8+9+10+11

Step-by-step explanation:

The initial value is 5 miles

We add 1 mile each day

a1 =5

a2 = 5+1 =6

a3 = 6+1=7

a4 =7+1 = 8

a5= 8+1 =9

a6= 9+1=10

a7 = 10+1 = 11

The series is the sum of the seven terms

a1+a2+a3+a4+a5+a6+a7

5+6+7+8+9+10+11

2. A chemist has a 25% and a 50% acid solution. How

AnnZ [28]

Answer:

x is mL of 25% acid and y is mL of 50% acid

We set up 2 equations:

A) x + y = 250

B) .25 x + .50y = .35 * 250 which equals

B) .25x + .50y = 87.50 Multiplying A) by -.5

A) -.5x -.5y = -125 adding the equations we get

-.25x = -37.50

x = 150 mL

y = 100 mL
