Find x and y please!! I’m desperate!!!
Answer:
x = 4
y = 2
Step-by-step explanation:
the third angle of the triangle
180 - (148 + 18) = 14º
Therefor
3x + y = 14
5x - y = 18
Add the equations
8x = 32
Divide both sides by 8
x = 4
Plug in x = 4
3(4) + y = 14
12 + y = 14
y = 2
9514 1404 393
Answer:
(x, y) = (4, 2)
Step-by-step explanation:
The triangles are similar by AA similarity, so the corresponding angles are congruent.
5x -y = 18 . . . . . . unmarked angles are congruent
18 +(3x+y) +148 = 180 . . . . . sum of angles in a triangle is 180°
__
After subtracting 166 from both sides, the second equation simplifies to ...
3x +y = 14
Adding this to the first equation gives ...
8x = 32
x = 4 . . . . . . divide by 8
Then substituting for x in the first equation gives ...
5(4) -y = 18
20 -18 = y = 2
The values of the variables are x = 4, y = 2.

If the room is a 14 by 12' rectangle then the strip of wallpaper needs to be at least how long?
Answer:
52 ft.
Step-by-step explanation:
In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.
So, rectangles has opposite sides equal, therefore, the perimeter should be:
; having L as the larger side.
Hence, the strip of wallpaper needs to be as least 52 ft.

On average, Carson spends about 26% of his allowance each month on candy and soft drinks. When creating a circle graph of what Carson does with his money, which of the following fractions would be the best to represent how much he spends on food?
Estimate the circumference of a circle that has a diameter of 6 ft.
Answer: 1/4
Given : On average, Carson spends about 26% of his allowance each month on candy and soft drinks.
To Find : When creating a circle graph of what Carson does with his money, which of the following fractions would be the best to represent how much he spends on food?
If these are your Choices:
A) 1/4
B) 1/3
C) 3/4
D) 1/2
Solution:
To Convert fraction into % multiply by 100
(1/4) * 100 = 25 %
(1/3) * 100 = 33.33 %
(3/4) * 100 = 75 %
(1/2) * 100 = 50 %
Therefore 1/4 fraction best represent how much he spends on food
(ii) Explain why a+b+c= 235°
This is a cornet maths question. How do I solve it
Answer:
Where is the image?
Step-by-step explanation:
Tell me in comments
The equation a + b + c = 235 is true because a = c = 55° and b = 125°
How to prove that a + b + c = 235?The angle a and 125° are on the same straight line.
So, we have:
a + 125° = 180°
Subtract 125 from both sides
a = 55°
The angle b and 125° are vertical angles
So, we have:
b = 125°
The angle a and angle a are vertical angles
So, we have:
c = a
This gives
c = 55°
Add the three angles
a + b + c = 55° + 125° + 55°
Evaluate the sum
a + b + c = 235°
Hence, it is true that a + b + c = 235°

If a cot α = 1 and b cos α = 1, find a2 – b 2
The equivalent expression of the different of two square is -1
Given the following expressions
a cot α = 1
a = 1/cot α = sinα/cosα
b = 1/cos α
We are to find the expression a² - b²
According to difference of two squares;
a² - b² = (a + b) (a - b)
Substitute the given expressions into the formula as shown:
[tex]a^2 - b^2 = (\frac{sin \alpha}{cos \alpha} )^2 - (\frac{1}{cos \alpha} )^2\\a^2 - b^2=\frac{sin^2 \alpha}{cos^2 \alpha} -\frac{1}{cos ^2 \alpha}\\a^2 - b^2=\frac{sin^2 \alpha-1}{cos^2\alpha}\\a^2 - b^2=\frac{-(1-sin^2\alpha)}{cos^2\alpha} \\a^2 - b^2=\frac{-os^2 \alpha}{cos^2 \alpha}\\a^2 - b^2 = -1[/tex]
This shows that the equivalent expression of the difference of two squares is -1

Find the x- and y-intercepts of the equation.
4x − 2y = 2
(A) (1/2,0). (0,1)
(B). (2, 0), (0, −1)
(C). (2, 0), (0, −1)
(D). (1/2, 0), (0, −1)
Answer:
Option D
Step-by-step explanation:
Convert to slope-intercept form:
[tex]4x-2y=2[/tex]
[tex]-2y=2-4x[/tex]
[tex]y=-1+2x[/tex]
[tex]y=2x-1[/tex]
Find the x-intercept by plugging in y=0:
[tex]y=2x-1[/tex]
[tex]0=2x-1[/tex]
[tex]1=2x[/tex]
[tex]\frac{1}{2}=x[/tex]
[tex]x=\frac{1}{2}[/tex]
Therefore, the x-intercept is [tex](\frac{1}{2},0)[/tex]
Find the y-intercept by plugging in x=0:
[tex]y=2x-1[/tex]
[tex]y=2(0)-1[/tex]
[tex]y=0-1[/tex]
[tex]y=-1[/tex]
Therefore, the y-intercept is [tex](0,-1)[/tex]
So, the correct answer is option D.
Answer:
D
Step-by-step explanation:
1. To find the x intercepts, set y equal to 0 and solve for x
4x - 2y = 2
4x -2(0) = 2
4x - 0 = 2
4x = 2
x = 1/2
2. To find the y intercepts, set x equal to 0 and solve for y
4x - 2y = 2
4(0) - 2y = 2
0 - 2y = 2
-2y = 2
y = -1

Your mother bought 2 kilograms of chicken and 3 kilograms of pork to consume in week. How many kilograms of chicken and pork did your family consume in a month?
Answer:
20?.... seems right to me.
Step-by-step explanation:
9514 1404 393
Answer:
20 kg
Step-by-step explanation:
The mass of the chicken and pork for 1 week is (2 kg) +(3 kg) = 5 kg.
Normally, we think of a month as 4 weeks.
(4 wk)(5 kg/wk) = 20 kg
If pork and chicken are consumed at the same rate for 4 weeks, the family will consume 20 kg of pork and chicken.
_____
If we consider a year to be 52 weeks (it is actually 1 or 2 days longer), then the number of weeks in an average month is ...
52/12 = 4 1/3 weeks/month
Multiplying that value by 5 kg/week will give 21 2/3 kg per month.
__
The answer depends on the assumption you make about weeks in a month.

Find the next three terms of the arithmetic sequence.

Question 9 options:
a)
16, 13, 10
b)
17, 20, 23
c)
22, 25, 28
d)
23, 26, 29
Answer:
c
Step-by-step explanation:
There is a common difference d between consecutive terms of an arithmetic sequence, that is
d = 13 - 10 = 16 - 13 = 19 - 16 = 3
To obtain the next term add the common difference 3 to the previous term.
a₅ = a₄ + 3 = 19 + 3 = 22
a₆ = a₅ + 3 = 22 + 3 = 25
a₇ = a₆ + 3 = 25 + 3 = 28
The next 3 terms are 22, 25, 28 → c
