Answer:
m∠B = 94º
Step-by-step explanation:
Supplementary angles total 180
(8x + 6) + ( 7x + 24) = 180
Combine like terms
15x + 30 = 180
15x = 150
x = 10
m∠B = 7x + 24
m∠B = 7(10) + 24
m∠B = 94º

Answer/Step-by-step explanation:
✔️10x - 4y = -8
-5x + 6y = 10
Multiply the first equation by ½ to eliminate the x-term
Thus:
½ × 10x - 4y = -8 (eqn 1)
5x - 2y = -4
✔️-2x + 6y = 3 (eqn 1)
4x + 3y = 9
To eliminate the x-terms when adding to the second equation, multiply the first equation by 2
Thus:
2 × -2x + 6y = 3
-4x + 12y = 6
✔️3x - 8y = 1 (eqn 1)
6x + 5y = 12
To eliminate the x-terms when adding to the second equation, multiply the first equation by -2
Thus:
-2 × 3x - 8y = 1 (eqn 1)
-6x + 16y = -2
✔️-8x + 10y = 16 (eqn 1)
-4x - 5y = 13
To eliminate the x-terms when adding to the second equation, multiply the first equation by -½
Thus:
-½ × -8x + 10y = 16 (eqn 1)

In parallelogram GHJK if m∡GHJ=140˚ find m ∡KGH.
Answer: m∠x = 40°
Step-by-step explanation:
This works the exact same way as the other one
Being adjacent angles in a parallelogram, the two angles would be supplementary (add up to 180°).
140° + x° = 180°
x = 40°

Find the length of AC
Answer:
let's use Pythagoras theorem,
h²=b²+l²
so,

√27 can be written as 3√3,
hence ac= 3√3
In the triangles, GK PN and HG 2MP.
Which statement correctly compares the angles?

Angle G is congruent to angle P.
O Angle G is smaller than angle P.
O Angle G is larger than angle P.
O Angle G is congruent to angle N.
32 cm
40 cm
G
K
P
N
Answer:
G is smaller than P. Visually comparing G to P you are doing a rough comparison to a 90° (or right) angle. Angle G is a little bit tilted to the right making it just under 90°
The statement which correctly compares the angles is Angle G is smaller than angle P.
What is Congruence of Triangles?Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.
Given are two triangles.
Given that,
GK is congruent to PN.
HG is congruent to MP.
Also, given that,
HK = 32 cm and MN = 40 cm
Angle G is opposite to the side HK.
Angle P is opposite to the side MN.
Angles opposite to the greater side will be greater.
So angle P is greater than angle G
Or, angle G is smaller than angle P.
Hence, Angle G is smaller than angle P.

El perímetro de un rectángulo es 58 y su base excede en 10 a su ancho, ¿Cuánto mide la base? AYUDAAAA
Answer:
The base is 19.5.
Step-by-step explanation:
The given question is, "The perimeter of a rectangle is 58 and its base exceeds its width by 10, how long is the base?"
Perimeter = 58
Base, l = 10+b
The perimeter of a rectangle is :
P = 2(l+b)
58 = 2(10+b+b)
29 = (10+2b)
29-10 = 2b
19 = 2b
b = 9.5
Base, l = 10 + 9.5
= 19.5
Hence, the base is 19.5.

Joe and Becky are buying fish for their new aquarium. The expression 3g + 4a represents the cost in dollars of buying fish
where 'g' is the number of guppies purchased and 'a' is the number of angel fish purchased. Find the cost of fish if they buy 12 guppies and 4 angel fish. Explain your work.
Answer:
$52
Step-by-step explanation:
Find the cost by plugging in 12 as g and 4 as a into the expression:
3g + 4a
3(12) + 4(4)
36 + 16
= 52
So, the cost will be $52
What is an equation of the line that is perpendicular to 3z +y=-5 and passes through the point (3, – 7)?
Enter your equation in the box
Solve the equation below :
7/8 = q + 1/2
A : q = 3/8
B : q = 1 3/8
C : q = 7/16
D q = 1 3/4
Answer:
q = -3/8
Step-by-step explanation:
Clearing out the fractions first simplifies this problem. The LCD here is 8, so we multiply all three terms of 7/8 = q + 1/2 by 8 and simplify the result:
7 + 8q = 4.
Combining the constants, we get: 8q = 4 - 7, or 8q = -3.
Finally, solve for q:
q = -3/8
Find the value of x in the triangle shown below
Answer:
x = 48°
Step-by-step explanation:
Two sides of the triangle are equal, both 7, Then the 2 base angles are congruent, both 66°
The sum of the 3 angles in the triangle sum to 180° , so
x = 180° - (66 + 66) = 180° - 132° = 48°

Lanu draws a rectangle that is 10 inches wide and 20 inches long. Which rectangle described down below has the same area
Answer:
b. 8 inches wide and 25 inches long
Step-by-step explanation:
Here are the options
5 inches wide and 25 inches long
b. 8 inches wide and 25 inches long
c. 15 inches wide and 15 inches long
d 15 inches wide and 25 inches long
Area of a rectangle = length x width
10 x 20 = 200
first option
5 x 25 = 125 does not have the same area as the one lanu drew
second option
8 x 25 = 200 has the same area as the one lanu drew
third option
15 x 15 = 225 does not have the same area as the one lanu drew
fourth option

What is the area of the circle in terms of pi?
Answer:
[tex]4.2025\pi\:\mathrm{m^2}[/tex]
Step-by-step explanation:
The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, we're given a diameter of 4.1. All diameters of a circle are exactly 2 times the length of all radii of the circle. Therefore, the radius of the circle is [tex]4.1\cdot \frac{1}{2}=2.05[/tex].
Thus, the area of the circle is [tex]2.05^2\pi=\boxed{4.2025\pi\:\mathrm{m^2}}[/tex]
! Task 1. Bookwork code: G24 Calculator X not allowed Anthony has three number cards, as shown below. The minimum of the three cards is 6. The range of the three cards is 5. What is the mean of Anthony's three cards? Cards are 6, 7 and unknown
Answer:
8
Step-by-step explanation:
In order to find the range you need to subtract maximum card number from the minimum card number. We know that the range is 5 and that the minimum card is 6 so we can set up the equation like this to find the maximum shown as x.
[tex]5=x-6[/tex]
Add 6 to both sides
[tex]11=x[/tex]
Now we know all the the numbers of the three cards Anthony has since we were given the minimum = 6, 7, and solved for the last card which was the maximum = 11. In order to find the mean we have to add all of the numbers then divide by how many numbers there are (in this case it will be 3):
[tex]mean=\frac{6+7+11}{3}[/tex]
Add 6+7+11
[tex]mean=\frac{24}{3}[/tex]
Divide by 3
[tex]mean=8[/tex]
Solve 36 = byx for y.
y=-
Step-by-step explanation:
Simplifying
36 = byx
Solving
36 = bxy
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-1bxy' to each side of the equation.
36 + -1bxy = bxy + -1bxy
Combine like terms: bxy + -1bxy = 0
36 + -1bxy = 0
Add '-36' to each side of the equation.
36 + -36 + -1bxy = 0 + -36
Combine like terms: 36 + -36 = 0
0 + -1bxy = 0 + -36
-1bxy = 0 + -36
Combine like terms: 0 + -36 = -36
-1bxy = -36
Divide each side by '-1xy'.
b = 36x-1y-1
Simplifying
b = 36x-1y-1
Answer:
y = [tex]\frac{36}{bx}[/tex]
Step-by-step explanation:
Given
36 = byx ( isolate y by dividing both sides by bx )
[tex]\frac{36}{bx}[/tex] = y
