........

Answers

Answer 1
Answer:

Answer:

14h+15

Step-by-step explanation:

(7h + 7) + (7h + 8)

First simplify

Eliminate redundant parentheses

(7h+7)

7h+7+7h+8

Add the numbers

7h+(7)+7h+(8) .      7+8=15

7h+15+7h

Combine like terms

(7h)+15+(7h)         (7h)+(7h)=14h

14h+15

The answer would be 14h+15

A three-digit number has two properties. The tens-digit and the ones-digit add up to 5. If the number is written with the digits in the reverse order, and then subtracted from the original number, the result is 792. Use a system of equations to nd all of the three-digit numbers with these properties

Answers

Answer:

The three-digit numbers with these properties are 850 or 941.

Step-by-step explanation:

Let x be the hundreds digit, y the tens digit, and z the ones digit. The first condition says that y+z=5. The second condition is:

the original number is (100x+10y+z) while the reversed number is (100z+10y+x) so

(100x+10y+z)-(100z+10y+x)=792\n99x-99z=792

Now we have the system

y+z=5\n 99x-99z=792

You can divide by 99 to simplify the second equation.

y+z=5\n x-z=8

Note that x, y, z must be digits between 0 and 9 and x\neq 0. If z>1, then the second equation forces x>9, for example z=2 so x-2=8, x=10 which is impossible. If z=0, you get x=8, y=5 and the number is 850. If z=1, you get x=9,y=4 and the number is 941.

There are 45 new houses being built in a neighborhood. Last month, 1/3 of them were sold. This month, 1/5 of the remaining houses were sold. How many houses are left be sold?

Answers

45 new houses.....last month 1/3 were sold....
1/3(45) = 45/3 = 15 houses sold last month

this month, 1/5 of the remaining houses were sold...
remaining houses left are (45 - 15) = 30
1/5(30) = 30/5 = 6 houses sold this month

houses left : 45 - 15 - 6 = 45 - 21 = 24 houses remain <==

Write the slope-intercept form of an equation of the line that passes through (a, - 4) is parallel to the graph of 4x - y = 2 y = - 1/4 * x + 4 y = 1/3 * x - 4 y = 4x - 4 D y = - 4 - 4

Answers

The first questionsanswer:

Given (0, -4), 4x - y = 7. I converted the equation into slope intercept form and I got: y = 4x - 7. Once I had gotten that I put (0, -4) and the equation into Point-Slope Form and solved it: y - (-4) = 4(x + 0),  y + 4 =  4x,  y = 4x - 4 is the slope intercept form of your equation and point :)
