Answer:
[tex]40^{\circ},\:40^{\circ},\: 100^{\circ}[/tex]
Step-by-step explanation:
The interior angles of any triangle always add up to [tex]180^{\circ}[/tex]. In an isosceles triangle, (at least) two sides are congruent and therefore their base angles are also congruent. We can then form the following equation:
[tex]2x+2x+5x=180[/tex], where [tex]x[/tex] is some constant.
Solving, we get:
[tex]9x=180,\\x=20[/tex]
Therefore, plugging our constant back in, our angles are:
[tex]2(20),\: 2(20), \: 5(20), \\\fbox{$40^{\circ},\:40^{\circ},\: 100^{\circ}$}[/tex].
Note this is only one group of possible angles. We could've also set the angle represented by [tex]5x[/tex] to be the pair of angles that are congruent, and depending on your definition of isosceles, each angle measure could be [tex]60^{\circ}[/tex] (equilateral).
Answer:
100, 40, 40
Step-by-step explanation:
First, do 2x+2x+5x because an isosceles triangle has two equal angles. We know that a triangle's total angle is 180 degrees so we do 180/9=20 x=20. Then multiply 2 by 20 to get 40. Then multiply 5 by 20 to get 100. So you get 40 40 100.

What is the result of subtracting the second equation from the first?
x−3y=6
−8x−y=6
Answer:
9x - 2y = 0
Step-by-step explanation:
Given
x - 3y = 6 → (1)
- 8x - y = 6 → (2)
Subtracting (2) from (1) term by term gives
x - (- 8y) - 3y - (- y) = 6 - 6 , that is
x + 8y - 3y + y = 0
9x - 2y = 0

Which equation represents the line that passes through the points (-3, 7) and (9,-1)? oy--3x+5 o y=-x-7 o y=zx-7 oy - 12 2x+5
Answer:
use the slope equation (y2-y1) / (x2 -x1). plug in values and solve
(-1 -7) / (9 -(-3)) (subtracting a negative is the same as adding a positive)
-8 / 12 (simplify)
m = -2/3
then, plug in one of the points and the slope into the slope-point equation.
(y - y1) = m (x - x1) (the point-slope form)
y - 7 = -2/3( x - (-3)) (plug in the slope and point 1 values, then solve)
y - 7 = -2/3x - 2 (add 7 to both sides)
y = 2/3x +5 (the answer)

A company claims that their new bottle holds 25% more laundry soap. If their original container held 80 fluid ounces of soap, how much does the new container hold?
Answer: The new container folds 100 fluid ounces.
Step-by-step explanation:
Given: A company claims that their new bottle holds 25% more laundry soap.
If original container hold 80 fluid ounces.
Then, Quantity of soap in the new container = 80 fluid ounces + 25% of 80 fluid ounces
= [80+0.25 x 800] fluid ounces [ 25% = 0.25]
= 80+ 20= 100 fluid ounces
Hence, the new container folds 100 fluid ounces.

Answer:
a). x = 10.20 in
b). x = 2.24
Step-by-step explanation:
a). By applying Pythagoras theorem in the given right angle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
(15)² = x² + (11)²
225 = x² + 121
x² = 225 - 121
x² = 104
x = √104
x = 10.198 ≈ 10.20 in
b). By applying Pythagoras theorem,
(3x)² = (2x)² + (5)²
9x² = 4x² + 25
9x² - 4x² = 25
5x² = 25
x² = 5
x = √5 = 2.24

A recipe for lemonade calls for 6 cups of lemonade for every 24 cups water. Which equation can be used to find x, the percent of lemonade in the recipe? (HINT: think of how much total lemonade and water is being used) *
Answer:
To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total
TWO of the six are lemon 2/6 x 100 = 33.33% Lemon the rest is water 100-33.33= 66.67% water
OR
FOUR out of the SIX are water 4/6 x 100 = 66.67% Water
Step-by-step explanation:
2. Use the Pythagorean Theorem to find x.
9.2
16.5
Your answer
Answer:
The value of x = 13.7.
Step-by-step explanation:
Given
Hypotenuse = c = 16.5
a = 9.2
To determine
x = b ?
For a right-angled triangle with sides a, and b the hypotenuse is defined as
[tex]c=\sqrt{a^2+b^2}[/tex]
In our case, we have to get x
[tex]b=\sqrt{c^2-a^2}[/tex]
so substituting b = x, c = 16.5, a = 9.2
[tex]x=\sqrt{16.5^2-9.2^2}[/tex]
[tex]x=13.7[/tex]
Therefore, the value of x = 13.7.
Find the solution to the system of linear equations below.
x - y = 0
3x + 2y = 10

Answer:
the desired solution is (2, 2)
Step-by-step explanation:
Solve this using elimination by add'n/subtr'n.
Multiply the first equation by 2, obtaining the equivalent set of equations:
2x - 2y = 0
3x + 3y = 10
Combining like terms, we get 5x = 10, and thus x must be 2.
Subbing 2 for x in the first equation yields 2 - y = 0, or y = 2.
Then the desired solution is (2, 2).

Answer:
y = 2. It is a horizontal line.
Step-by-step explanation:
The asymptote is the line that the function comes close to touching, but never will. Because the range is y > 2, you know that any value greater than 2 can and will be a y-coordinate, but the function will never have 2 as a y-coordinate. It will never touch the line y = 2, and therefore, y = 2 is the asymptote. Hope this helps!

Answer:
n < 5
Step-by-step explanation:
6(3 + n) < 48
when you see parentheses you multiply so it would be 6 x 3 which is 18 then 6 x n which would be 6n so it simplified some would be 18 + 6n < 48 then to get the numbers on the same side and 6n on the other you would -18 from both sides so the one on the left side of the equation cancels out 6n < 48 - 18 then do the math which would be 30 then you divide by 6 to get the n by itself 30/6 is 5 so n is smaller than 5 or n < 5
pls help me, here's the screenshot and see how y'all can help me
We can say that the y intercept is at the location (0,-1)
This is where the graph crosses the vertical y axis. This is 1 unit below the origin.
This is assuming each tickmark on the grid represents 1 unit.
Answer:
The y- intercept is (0,-1)
Step-by-step explanation:
A y- intercept is when a point intercepts (crosses) the y- axis. Since the dot does not cross the x- axis, that point will be 0. It is below the y- axis, meaning it will be -1.
24[tex]24\leq 8(7-4x)[/tex]
Answer:
Inequality Form: x ≤ 1
Interval Notation: (−∞, 1]
Step-by-step explanation:
24 ≤ 8 (7 − 4x)
Rewrite so x is on the left side of the inequality.
8 (7 − 4x) ≥ 24
Divide each term by 8 and simplify.
Divide each term in 8 (7 − 4x) ≥ 24 by 8.
8 (7 − 4x)/8 ≥ 24/8
Cancel the common factor of 8.
7 − 4x ≥ 24/ 8
Divide 24 by 8.
7 − 4x ≥ 3
Move all terms not containing x to the right side of the inequality.
−4x ≥ −4
Divide each term by −4 and simplify.
x ≤ 1
The result can be shown in multiple forms.
Inequality Form: x ≤ 1
Interval Notation: (−∞, 1]
Pablo folds a straw into a triangle with side lengths of 4x2-3 inches,4x2-2 inches, and 4x2-1 inches.Which expression can be used to find the perimeter of the triangle?
Answer:
The expression to find the perimeter is [tex]12x^2-6[/tex].
Step-by-step explanation:
Given: The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.
To find: The expression that can be used to find the perimeter of the triangle.
Solution:
We have,
The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.
We know that,
The perimeter of a triangle is sum of all the sides.
So, Perimeter [tex]=(4x^2-3)+(4x^2-2)+(4x^2-1)[/tex]
[tex]\implies \text{Perimeter}=12x^2-6[/tex]
Hence, the expression to find the perimeter is [tex]12x^2-6[/tex].
