Jenna has $43 and Heidi has $17.

Step-by-step explanation:

Total amount = $60

Let,

Amount of Jenna = x

Amount of Heidi = y

According to given statement;

x+y=60   Eqn 1

x=2y+9   Eqn 2

Putting value of Eqn 2 in Eqn 1;

(2y+9)+y=60\\2y+9+y=60\\3y=60-9\\3y=51

Dividing both sides by 3,

\frac{3y}{3}=\frac{51}{3}\\y=17\\

Putting y=17 in Eqn 2

x=2(17)+9\\x=34+9\\x=43

Jenna has $43 and Heidi has $17.

Given the function f(x)=x^2+2x+1, find each value of the function
Paha777 [63]

Answer:

1 9/16

Step-by-step explanation:

F(1/4) means u plug in 1/4 for x

so the equation would be

f(1/4)=1/4^2+2 1/4 + 1

f(1/4)=1/16+1/2+1

f(1/4)= 9/16 +1

f(1/4)= 1 9/16

its not nine teen its one and 9 over 16 just clarification

The sum of five different positive integers is 320. The sum of the greatest three integers in this set is 283. The sum of the gr
Nina [5.8K]

Answer:

17

Step-by-step explanation:

Let a,b,c,d,x represent the five integers in Ascending order.

Given;

The sum of five different positive integers is 320

a+b+c+d+x = 320 .......1

The sum of the greatest three integers in this set is 283

c+d+x = 283 .....2

The sum of the greatest and least integers is 119

a+x = 119 ......3

For the largest possible value;

From equation 3, if a is as low as 1,

x = 119-1 = 118

x = 118

For the least possible value;

Subtract equation 2 from 1

a+b = 320-283 = 37

We know that a cannot be higher than b, so the highest possible value of a is;

a = 37-b

a = 37- 19 = 37-19

a = 18

Substituting into equation 3

x = 119-18 = 101

Difference;

∆x = 118-101 = 17
