Answer:
{1} x + 2y = 13
{2} 3x - 5y = 6
x = 13 - 2y
substituting into {2}
3x -5y = 6
3( 13 - 2y) - 5y = 6
39 - 6y -5y = 6
-11y = 6 -39
y = -33 /-11
( minus and minus cuts in fraction, so the answer will come in positive)
y = 3
now , substituting into {1}
x + 2(3) = 13
x = 13 -6
x = 7
so,
the solution are:-
x = 7
y = 3
I hope this helps a little bit.

Answer:
a.
2x+4x+3x=180 sum of interior angle of the triangle is 180
9x=180
x=180/9=20
b.
x-20+x+10+x-20=180sum of interior angle of the triangle is 180
3x-30=180
3x=180+30
x=210/3=70
c.x+10+x+20+x=180 linear pair
3x+30=180
3x=180-30
x=150/3=50
Answer:
A: x=20
Step-by-step explanation:
angles in a triangle always equal 180° so knowing this 2x+3x+4x=180
9x=180
9x÷9=x
180÷9=20

1/4x1/4 as a fraction I’m sorry guys
Step-by-step explanation:
1/4x1/4
fraction =1/16
The value of the expression [tex]\frac{1}{4} * \frac{1}{4}[/tex] can be expressed as as a fraction as [tex]\frac{1}{16}[/tex]
What is fraction ?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator. Every number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
Given [tex]\frac{1}{4} * \frac{1}{4}[/tex]
Then we can multiply the numerators as well as the denominators which will gives us

Order the side from greatest to least.
Η.
28°
118°
K
J
side [Select ]
Answer:
HJ>KJ>HK
Step-by-step explanation:
Side opposite to the largest angle is the largest.
Side opposite to smallest angle is the smallest.
ang K = 118° ang J = 28°
ang K + ang J + ang H = 180° (Sum of all the angles in the triangle is 180°)
118°+28°+angH=180° (Putting the values of ang K & ang J)
146°+angH=180°
ang H=180°-146°
ang H=34°
128°>34°>28°
ang K>ang H>ang J
Here, ang K is the largest, so the side opposite to it i.e. HJ will be the largest side.
Smaller than ang K and bigger than ang J is ang H, so the side opposite to it i.e. KJ will be smaller than HJ but bigger than HK.
Ang J is the smallest angle, so the side opposite to it i.e. HK will be the smallest.
HJ>KJ>HK.

x + 7.
Step-by-step explanation:
The answer is X + 7 because you know, 8x + 13 and if 7x - 9 we're solded. We remove 7x at 8x so at least we have only one x and we remove 9 than 16 so we have 7. That's why the reply is x + 7. Sorry if I wasn't clear, I am not really good at english.

Answer:
True
Step-by-step explanation:
Let's take a problem such as 3x-2=6
To isolate the variable, you must get rid of everything on one side and essentially do the inverse to the other side. We see -2, so you have to add 2 to each side.
Now you have 3x=8
Next, we device each side by 3. Right now, x is being multiplied by 3 so we have to do the inverse.
Answer is x = 8/3 or 2.666666666666667

Find the measures of the angles and arcs identified below
Answer:
∠a = 42.5°
∠b = 87°
∠c = 174°
∠d = 90°
∠f = 131°
Step-by-step explanation:
∠a = 85°/2 = 42.5°
∠b = 360° -110° - 76° = 174°/2 = 87°
∠c = 360° -110° - 76° = 174°
∠d = 90°
∠f = 360° - 101° - (64° x 2) = 131°

show work to determine if (1,4) is a solution to the system: y - 2x = 2 and y=4x - 6
Answer:
not a solution
Step-by-step explanation:
To determine if (1, 4) is a solution to the system
Substitute x = 1, y = 4 into the equations and check validity
y - 2x = 2
y - 2x = 4 - 2(1) = 4 - 2 = 2 = right side ← True
4x - 6 = 4(1) - 6 = 4 - 6 = - 2 ≠ 4 ← False
First equation is satisfied but second is not
Thus (1, 4) is not a solution of the system
