First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]
[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.

i in 3rd grade doing advanced wok, i need help!
Answer:
64,1578
Step-by-step explanation:
your welcome
PLEASE HELP QUICKLY!!
Answer:
79
Step-by-step explanation:
Sense all the lines are straight, and will never cross, then adjacent angles must always add up to 180 degrees. 3 and 4 are adjacent. Thus they must add up to 180. So set up as 101 + x = 180. x=180 - 101, and find that x = 79. Plug x back into check. 101 + 79 = 180. and 180= 180. The answer is 79 degrees.

Answer:
101 cm (to 3 sf)
Step-by-step explanation:
-First you want to find side CD:
. Draw a line from point C directly down to make a right angled triangle (you can lable the extra point whatever letter you want but for this explanation it's gonna be x)
. You know that CX will be 16.7cm because its the same length as BA
. To find CD you need to use SOH,more specifically the hypotenuse using SOH
. H=O/S (O=16.7, S= sin(43))
.put this in your calculator and you'll get CD=24.4868624 (don't round yet)
-now you wanna find AD but more specifically XD because that's the little part you don't know:
. Using the same triangle from earlier, we use CAH now to find A (aka XD)
. A=C*H (C=cos(43), H=24.4868624 (the value of H/CD from the previous calculation)
. That should give you: 17.90855746
. You're still not done, do 17.90855746+21.2=39.10855746 (this is your value for AD
-add all your values now:
39.10855746+24.4868624+16.7+21.2=101.4954199
-now round to 3 significant figures:
101.4954199 -> 101cm
The perimeter is 101cm

The image is just darkness what do you mean
Step-by-step explanation:
what is x + y = -9 in y=mx+b form
Answer: Talk the Talk. Once a linear equation is solved for y, it is in slope-intercept form, y = mx + b. The coefficient of the x term, m, is the slope of the line and the number (or constant), b, is the y-intercept.

Step-by-step explanation: pythagorean theorem
215^(2)+x^(2)=330^(2)
46225+x^(2)=108900
x^(2)=62675
x=5√2507
x=250.35
Answer:
250.35 yards
Step-by-step explanation:
Use the pythagorean theorem to find the height.

Whats the slope form?
Answer:
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept).
Answer is Ax+By=C. ... A, B, C are integers (positive or negative whole numbers)
Step-by-step explanation:
Plz mark brainliest
Step-by-step explanation:
I'm assuming you mean Point- Slope Form of a linear equation.
If so, then a point slope form of a linear equation is one that looks something like this:
y - y₁ = m (x - x₁)
where (x₁, y₁) is a point on the line and m is the gradient of the line.

What is the slope between (2,1); (5,9)
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Answer:
[tex]\frac{8}{3}[/tex]
Step-by-step explanation:
(2, 1)
(5, 9)
Find the slope
____________
When finding slope, we always have to follow the formula :
[tex]\frac{y^2-y^1}{x^2-x^1}[/tex]
The y in the fraction are the second number within the coordinate points, while the exponents are the second number from the second point and the first number from the first point. The same goes for x. Therefore substitute x and y with their corresponding values :
[tex]\frac{9-1}{5-2}[/tex]
[tex]\frac{8}{3}[/tex]
If △ABC∼△LMN and △LMN∼△XYZ, is △ABC∼△XYZ? Use the AA similarity criterion to support your answer.
Answer:
yes because transitive property
Step-by-step explanation:
if abc~lmn, then the angles a and b are similar to angles l and m. and if lmn~xyz then angles l and m are similar to angles x and y. therefore, using transitive property, angles a and b would be similar to angles x and y. so using AA similarity, the two triangles would be similar
The student council is organizing a school fair. Council members are making signs to show the prices for admission and for each game a person can play. If the school admission is $2 and the price per game is 25 cents, Let x represent the number of games. Which expression can you use to determine the total amount (in dollars) a person pays for admission and playing x games?
Answer:
$2 + 0.25x
Step-by-step explanation:
The expression would be
Let us assume the x be the number of games
And the school admission is $2 plus the price of game is 25 cents
So, based on the above information
The expression to determine the total amount is
= $2 + 0.25x
