Answer:
x = (5-(1/4*y))/(-2) why does there have to be 20 characters lol
Answer:
When simplifying using addition and subtraction, you combine “like terms” by keeping the "like term" and adding ... Solve the following equations for x: 1) x + 5 = 12. 2) x – 11 = 19. 3). 22 – x = 17 ... To get the x by itself, you will need to get rid of the 5 and the 3. ... We check the answer by putting it back in the original equation:.
Step-by-step explanation:
Answer:
x = -9, y = -3.
As an ordered pair it is (-9, -3).
Step-by-step explanation:
Substitute x = 3y in equation 1:
2y + 3y = -15
5y = -15
y = -15/5
y = -3.
Now find x by plugging y = -3 in x = 3y:
x = 3*-3 = -9.
Check the answer in equation 1:
2(-3) + -9
= -6 - 9
= -15 Correct.
Answer:
B ) b = 2 multiplied by A over 9 - 35
Step-by-step explanation:
b - the other base;
A = 9/2 ( b + 35 ) / * 2 ( we will multiply both sides of the equation by 2 )
2 A = 9 ( b + 35 )
b + 35 = 2 A / 9
b + 35 - 35 = 2 A / 9 - 35
b = (2 A / 9 ) - 35

Answer:
Step-by-step explanation:
Use <u> law of cosine</u> to calculate the other side.
c² = a² + b² -2ab Cos C
Here, c is the length of the side which is opposite side to ∠E
a = 29 ; b = 25 and C = 109
c² = 29² + 25² - 2*29*25*Cos 107
= 841 + 625 - 1450* (-0.2923)
= 1466 + 423.835
= 1889.835
c =√1889.835
c = 43.47 ≈ 43
No, find ∠D using again use <u>law of cosine</u>
<u></u>
β = ∠C = 34°
α = 180 - (34 +107)
α = ∠D = 39
Other angles are
∠C = 34° and ∠D°39
