Y -7.2 = 8 I need this as explanation and in algebraic show

valkas [14]

Answer:

Heyya !

Here's how to do it:-

First write down what's given:-

y -7.2 = 8

Next, we do like this:-

y = 8+ 7.2

We transferred 7.2 to the other side of the ' = ' sign.

When we do so, the sign of the number changes

Here 7.2 was negative first but when we transferred it to the other side, its sign changed to positive.

So,

y = 8 + 7.2

Now, just add it!

8 + 7.2 equals 15.2

<h2>So, the value of y is 15.2 </h2><h2 /><h3>I hope the explanation was clear.</h3><h3>If you still have doubts, let me know in the comments !</h3>

What is the slope and y-intercept of the graph?

ValentinkaMS [17]

Answer:

slope= -1

y-intercept = 24

Step-by-step explanation:

2x +2y=24

2x-24=-2y

divide by then u get:

-1x + 12= y

-1 is ur slope

<u>y-</u><u>intercept</u>

let x=0

y= -1(0)+12

y =0+12

y = 12

Tripp and Rico are two dogs. Tripp weighs exactly 35 pounds more than Rico. Together, they weigh exactly 49 pounds. How much doe

babymother [125]

Call the weights of the two dogs $t$ and $r$ .

We know that Tripp weights 35lbs more than Rico, or:
$t=r+35$

We also know that the total weight of both dogs is 49lbs.:
$t+r=49$

Now, by substitution:
$(r+35)+r=49$
$2r+35=49$
$2r+35-35=49-35$
$2r=14$
$r=\frac{14}{2}$
$r=7$
Rico weighs 7lbs.

Then:
$t=r+35$
$t=7+35$
$t=42$
Tripp weighs 42lbs.

To check our work:
$t+r=49$
$42+7=49$
$49=49$ CHECK!
