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.

Answer:

2

Step-by-step explanation:

Since if it's 5 or higher you go up but if it's 4 or lower you stay the same. And since 2.36 doesn't have the .5 it would round to 2

Find the volume of a cylinder with radius 4 m. And height 3 m.
katovenus [111]
V =  \pi r^25

Plug in the values

r = 4 ; h = 3

V= \pi *4^2*3

V = 3.14 * 16 * 3

V = 150.72

So approximately 150.7

-9x+7y=28 find the y intercept
natulia [17]

In slope-intercept form, we have these values (y = mx + b):

m = slope

b = y-intercept

Change the equation from standard form to slope-intercept form.

-9x + 7y = 28

-9x + 9x + 7y = 28 + 9x

7y = 28 + 9x

7y/7 = 28/7 + 9x/7

y = 4 + 9/7x

y = 9/7x + 4

Therefore, the y-intercept is 4.

Best of Luck!
