hello, can you please walk me through this problem
Answer:
x = 6, z=88
Step-by-step explanation:
The angle 92 and z lies on a straight line.
Therefore,
[tex]z + 92 = 180 \\ z = 180 - 92 = 88[/tex]
Same goes for Angle Z and 5x+62.
[tex]z + 5x + 62 = 180 \\ 88 + 5x + 62 = 180 \\ 150 + 5x = 180 \\ 5x = 180 - 150 = 30 \\ x = 30 \div 5 = 6[/tex]

Answer:
Chad is incorrect
Step-by-step explanation:
Since A is in quadrant 2, we know the x must be negative and y is positive. Therefore, if we add a negative sign in front of both x and y, x will become positive, and y will become negative. However, in the 3rd quadrant, both x and y must be negative, which is not the case here. Hence, Chad is wrong.

Find the value of x picture attached
Answer:
x = 10
Step-by-step explanation:
These angles are same side interior angles.
This means that (11x + 10) + (10x - 40) = 180
Solve for x:
11x + 10 + 10x - 40 = 180
21x - 30 = 180
+30 +30

Sixty percent of the water from the full bottle holding 1.5 L was used to fill 5 similar cups leaving no remainder. How much water does 1 cup hold ?
Answer:
0.9 of a Liter for the bottle's volume
0.18 L for each cut
180 mL for each cup.
Step-by-step explanation:
60/100 * 1.5 = 0.6 * 1.5 = 0.90
There were 5 cups
The volume of the bottle was 0.9 liters
1 cup held 0.9 / 5 = 0.18 L
1 Liter = 1000 mL
0.18 L = 1000 *0.18 = 180 mL

Answer:
7.4 in
Step-by-step explanation:
The diagonal divides the rectangle into 2 right triangles.
The diagonal is the hypotenuse and the length l is a leg ( adjacent) to angle
Using the cosine ratio in the right triangle
cos22° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{l}{8}[/tex] ( multiply both sides by 8 )
8 × cos22° = l , then l ≈ 7.4 in ( to the nearest tenth )

Answer this using a graphing method!
Step-by-step explanation:
5x-2y=10
x-y=-1
Addition method
multiply the second equation by -2 and add it to the first one
5x-2y=10
-2x+2y=2
Total 3x=12
Divide by sides by 3
x=4
Now multiply the second equation by -5 and add it to the first one
5x-2y=10
-5x+5y=5
3y=15
Divide both sides by 3
y=5
Solutions are x=4 and y=5
2nd method
if x-y=-1, so x=y-1
bring the value of x in the first equation
5(y-1)-2y=10
5y-5-2y=10
put the similar term together
3y=15
Divide both sides by 3
y=5
now bring the value of y in one of the equation
x-y=-1
so x-(5)=-1
x=-1+5
x=4
Solutions are x=4; y=5

Dracula's bill at the restaurant was $54.83. He left a tip of 15%.
What was the tip amount (nearest hundredth)?
PLEASE ANSWER QUICK :,(
15% as a decimal is 0.15
Multiply the amount of the bill by the percentage:
54.83 x 0.15 = 8.22
The tip was $8.22
Answer:
[tex]\huge\boxed{ \$ \ 8.22}[/tex]
Step-by-step explanation:
Bill = $54.83
Tip = 15 % of 54.83
[% means out of 100, "of" means to "multiply"]
Tip:
= 15% of 54.83
= 15 / 100 * 54.83
= 0.15 * 54.83
= $ 8.22

line y=3x-1 is transformed by a dilation with a scale factor of 2 and centered at (3,8) what is the lines image in an equation form
Answer: 4)y=3x-1
Step-by-step explanation:
The y value relates to the dilatation center, which the line image's equation will be [tex]y = 3x - 1[/tex]. In standard form, [tex]y = mx + b[/tex] y-intercept is represented by the letter b.
Center of dilatation calculation:[tex]y = 3x - 1[/tex] is the equation of a line.
If somehow the line is dilatable by a factor of 2 and centered at [tex](3, 8)[/tex]. To begin with, we must determine the y-value for which [tex]x = 3[/tex].
[tex]y = 3(3) - 1\\\\y = 9 - 1\\\\y = 8[/tex]
This equation of the line image will be [tex]y = 3x - 1[/tex], because the y value is comparable to the center of dilatation.

2)
(x-(x+0.7))/((x+0.7)-x)=
(x-x+0.7)/(x+0.7-x)=
(x-x+0.7)/(x+0.7+(-x))=
(x-x+0.7)/(x+0.7+(-x))=
(x-x+0.7)/(x+(-x)+0.7)=

The area of a rectangular pool is (x + 17x + 72) square meters. The dimensions of the pool are the factors of this polynomial. There is a 3-meter-wide concrete walkway around the pool. Write expressions to represent the dimensions of the outside border of the walkway. (Lesson 21.1)
Answer:
The walkway around the pool makes the entire outer dimensions (outer border)
x+9+2x3=x+15 and x+8+2x3
hope this helps! could i get brainliest plz?
The expressions to represent the dimensions of the outside border of the walkway is (x + 12) meters for the length and (x + 11) meters for the width.
Given area : [tex]x^2 + 17x + 72[/tex]
The factored form of the polynomial is:
[tex]x^2 + 17x + 72[/tex] = [tex]x^2 + 8x+9x+72[/tex]
= x(x+8)+9(x + 8)
=(x + 9)(x + 8)
So, the dimensions of the pool are (x + 9) meters and (x + 8) meters.
The length of the walkway = 3 meters wide
So, the length is added to each side of the pool.
Dimensions of the outside border of the walkway:
Length: (x + 9) + 3 = x + 12 meters
Width: (x + 8) + 3 = x + 11 meters
Therefore, the dimensions of the outside border of the walkway are
(x + 12) meters for the length and (x + 11) meters for the width.
