Three friends all have ages that are consecutive integers. The sum of their ages is 180. What is the age of the oldest friend?

Lynna [10]

Answer:

Step-by-step explanation:

Oldest friend=X+2; Middle friend=X+1; Youngest friend=X

X+(X+1)+(X+2)=180

3X+3=180 Subtract 3 from each side.

3X=177 Divide each side by 3

X=59 Youngest friend is 59.

X+2=59+2=61 ANSWER: Oldest friend is 61.

X+2=59+1=60 Middle friend is 60.

CHECK:

Sum is 180

59+60+61=180

180=180

Which of the following will always be true of a graph that is non-proportional?<br><br> please help.

creativ13 [48]

Given:

Consider any graph that is non-proportional.

To find:

The correct statement that is true of a graph that is non-proportional.

Solution:

We know that, if y is proportional to x, then

$y\propto x$

$y=kx$

where, k is constant of proportionality.

In these cases if x=0, then y=0. It means the graph always pass through the origin, i.e., (0,0).

So, if a graph is not passes through (0,0), then it is non-proportional.

Thus, non-proportional graph will not pass through (0,0).

Therefore, the correct option is A.

A recipe for nut bread calls for 2/4 cup of walnuts and 1/6 cup of pecans. What is

sashaice [31]

Answer:

$\frac{2}{3}$

Step-by-step explanation:

The question above is answered below.

$\frac{2}{4} + \frac{1}{6}$

Take the LCM of the denominators and simplify. The LCM is 12.

$\frac{6 + 2}{12}$

To get 6 + 2 above, we divide 12 by 4 which equals 3 then multiply 3 by 2, total 6. Similarly to get 2, we say 13 divided by 2, equals 2; 2 times 1 equals 2.

$= \frac{8}{12}$

The fraction above has to be simplified to reduced form. Thus the answer below.

$= \frac{2}{3}$

Therefore, the total amount of walnuts and pecans needed for the recipe is 2/3.

Use the Intermediate Value Theorem to show that there is a root of the given equation in the specified interval. ex = 3 − 2x, (0

raketka [301]

Answer:

$f(0)=-2\\f(1)=e-1$

Step-by-step explanation:

According to intermediate value theorem, if a function is continuous on an interval $[a,b]$ , and if $k$ is any number between $f(a)$ and $f(b)$ , then there exists a value, $x=m$ , where $a$ , such that $f(m)=k$

In the given question,

Intermediate Value Theorem is used to show that there is a root of the given equation in the specified interval.

Here,

$f(x)=e^x-3+2x$

Put $x=0$

$f(0)=e^0-3+2(0)=1-3+0=-2$

Put $x=1$

$f(1)=e^1-3+2(1)=e-3+2=e-1$

Explain why one half times two equals one whole

djverab [1.8K]

Two halfs equal one whole. think of it like this, an orange cut in half leaves you with two halfs, put them together and you have a whole. simple. multiplying by 2 just means adding a number two times.
1 half plus one half= 2halves= 1 whole
1half x 2= 2 halves=1 whole
