Chen’s house is 53 years old. This is 5 more than twice the age of Sunny’s house, h.

tankabanditka [31]

Answer:

The Equation which shows the equality is 53 = 2 h + 5 ,

The age of Sunny's house is 24 years old

Step-by-step explanation:

Given as ;

The age of the house of Chen's is 53 years old

Let the age of of the house of sunny = h years old

So, according to question

Chen's house age is 5 years more than twice the age of sunny's house

I.e Chen's house age = 2 × sunny's house age + 5

Or, 53 = 2 × h + 5

or, 2 × h = 53 - 5

so . 2 × h = 48

∴ h = $\frac{48}{2}$ = 24 years

Hence The Equation which shows the equality is 53 = 2 h + 5 , And The age of Sunny's house is 24 years old . Answer

How many different combinations of pennies, nickels, dimes, quarters, and half dollars can a piggy bank contain if it has 20 coi

ycow [4]

<span>Because there are 20 coins plus four bars = 24 items to choose. You want to choose where to put the four bars, thus C(24,4). There are four bars, not five. Note that four bars divide the 20 coins into five sections. Five bars would divide it into six, but we only have five different kinds of coins to choose from.</span>

Suppose we take the interval [−5,7] and divide it into 4 equal subintervals. Find the width Δn of each subinterval. Δn = If we n

lana66690 [7]

Answer:

$x_0=-5\\x_1=-2\\x_2=1\\x_3=4\\x_4=7$

Δn=3

Step-by-step explanation:

Remember, if we need to divide the interval (a,b) in n equal subinterval, then we need divide the distance (d) between the endpoints of the interval and divide it by n. Then the width Δn of each subinterval is d/n.

We have the interval [-5,7]. The distance between the endpoints of the interval is

$d=7-(-5)=12$ .
