Sheena baked 112 cookies she kept 16 cookies at home for her family and shared the rest evenly with her 8 friends how many cooki

sesenic [268]

Answer:

Each friend would get 12 cookies.

Step-by-step explanation:

Given:

Number of cookies she baked = 112 cookies

Number of cookies kept aside for family = 16

Number of friends she need to distribute cookies evenly = 8

We need to find number of cookies each friend would get;

Solution:

We will first find the number of cookies which needs to be distributed.

So we can say that;

number of cookies which needs to be distributed can be calculated by subtracting Number of cookies kept aside for family from Number of cookies she baked.

framing in equation form we get;

number of cookies which needs to be distributed = $112-16=96$

Now we will find number of cookies each friend would get.

number of cookies each friend would get can be calculated by dividing number of cookies which needs to be distributed from Number of friends she need to distribute cookies evenly.

framing in equation form we get;

number of cookies each friend = $\frac{96}{8}=12$

Hence Each friend would get 12 cookies.

What are the exact solutions of x2 + 5x + 1 = 0? (5 points)

Rus_ich [418]

Answer:

$x=\frac{-5\pm\sqrt{21} }{2}$

Step-by-step explanation:

We use the quadratic formula here which says for a quadratic equation $ax^2+bx+c=0$ .

$x= \frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Now in our case

$a=1\\b=5\\c=1$

so we have:

$x=\frac{-5\pm\sqrt{5^2-4(1)(1)} }{2(1)} =\frac{-5\pm\sqrt{21} }{2}$

$\boxed{x=\frac{-5\pm\sqrt{21} }{2} }$

Which are our solutions.

5x-7=5x bud it no solution one solution infinitely many solutions

blagie [28]

Answer:

When you add 2+3 which equals 5 so it’ll be y=5x-7. And plug in y into the other equation. 5x-7-5x+8=0. -7-8=0, -7-8 =-1 therefore there is no solution because-7-8= -1 not 0.
