10(5 + x) - 10 = 90 Solve
WRITE AN EQUATION

Answers

Answer 1
the equation is 50+10x-10 which would simply to 40+10x and then change the x to 5 ( now it’s 5 times 10 ) changing 10x to 50 . 50+40 equals 90 . GOOD LUCK
Answer 2
So if you use distributive property you would charge the equation to 50+10x-10=90 simplified even more it would be 10x+40=90
Subtract 40 from both sides to get 10x=50 divide both by 10 to get x=5

Go back and check work 10(5)+40=90
50+40=90
90=90

X=5

Good luck algebra is something else

Help pls! Find the slope

Answers

Answer:

slope is -1

Step-by-step explanation:

because it's going one unit down at a time

Answer:

Step-by-step explanation:

The slope, m, is defined as

m=(y2-y1)/(x2-x1)

So we just pick any two points. I’ll use (-3,5) and (5,-3)

m=(-3-5)/(5- -3)

m=-8/8

m=-1 so the slope is -1

Answer:

N = 8/4

Step-by-step explanation:

Multiply all terms by n and cancel:

1/2+1/2+1/2=7N

8/7=7n (Simplify both sides of the equation)

7n=8/7/7

           -

           7

(Divide both sides by 7)

n= 8/49

Look at the rectangle and the square:

A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.

Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.

Answers

Answer:

False

Step-by-step explanation:

Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:

[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]

We can do the same for the square in which ON = 6 because it's a square:

[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]

Now let's compare them:

8.5 X 2 = 17 so OM X 2 is not equal to SQ

The sentence is false.
