To do this, you have to change it into common denominators. The common denominator is 56, in this case. Multiply 5 by 8 because 56 divided by 7 is 8. There fore you would be adding 13/56 and 40/56. You would be 53/56. This is already in simplest form.

Answer:

y=3x+4

Step-by-step explanation:

The equation of the straight line that passes through (-3,-5) with slope 3 can be found using

$y = mx + b$

where m=3 is the slope .

We substitute the slope to get:

$y = 3x + b$

We substitute the point to find b.

$- 5 = 3( - 3) + b \\ - 5 = - 9 + b \\ b = - 5 + 9 = 4$

The equation of the straight line is:

$y = 3x + 4$

The product of two consecutive even integers is 48. Which equation can be used to find these integers?

Zigmanuir [339]

Since they are both even, let x and x + 2 be the integers.
x(x + 2) = 48
x² + 2x - 48 = 0
(x - 6)(x + 8) = 0

So, at x = 6 and x = -8.
So you can have 6 and 8 or -8 and -6 as your two integers.

Isabella painted her bedroom. She used 2 gallons of paint and finished in 8 hours. At what rate did Isabella paint the room?

GrogVix [38]

Answer: " \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " .

_______________

Step-by-step explanation:

_______________

This is a "unit rate" problem;

that is: we want to solve for a particular quantity per [single] unit.

_______________

→ in this case, per single "hour" ;

_______________

So we convert:

_______________

" 2 gal per 8 hours" ; to the correct number of:

_?_ gal per [single] hr.

_______________

{Note: "gal" refers to: "gallon(s)" ;

"hr" refers to: "hour(s)" .}.

_______________

→ " $\frac{2 gal}{ 8 hr} = [\frac{2}{8}]$ gal / hr. " ;

_______________

→ " { $\frac{2}{8} =$ [2÷2] / [8÷2] = 1/4 ;

_______________

So, the answer is:

→ " $\frac{1}{4} gal /hr$ " ;

_______________

or: write as decimal:

→ " $\frac{1}{4}$ = (1 ÷ 4) = 0.25 " ;

_______________

write the answer as:

_______________

→ " 0.25 gal/hr. "

_______________

Or, when we had:

→ "2/8" gal/hr ;

_______________

Use calculator:

→ " $\frac{2}{8}$ = "2 ÷ 8" ;

= " 0.25 gal/ hr.

_______________

So: The correct answer is:

_______________

" \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " ;

_______________

The number of seconds varies directly as the number of minutes. When 240 seconds have passed. 4 minutes have passed. If 420 seco

FromTheMoon [43]

Answer:

7 minutes.

Step-by-step explanation:

You can simply apply the well known rule if time: 60mins makes 1 hour,

or use proportion;

where x is the value you seek,

4=240

x=420

The relationship between 4 and 249 is 60 so,

420 divided by 60 equals 7 minutes.
