To solve this equation we must first plug in 5 for x.

<span> (5 - 4x)
</span>↓

(5 - 4 · 5)
The next step would be to multiply 4 by 5 to get rid of the parenthesis within our main parenthesis.

(5 - 4 · 5)

(5 - 20)
The next step would be to subtract both of the numbers within the parenthesis.

(-15)
Now we must multiply.
-

· 15 = -

-

Now we simplify our answer to get our final answer.
-5
Answer:

R= -7x+1
Step-by-step explanation:
Step-by-step explanation:
Add 75 to 12.55. the answer would be 87.55.
100+105=205
205-87.55=117.45
Answer:
21.9°
Step-by-step explanation:
In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.
We solve this above question using the Sine rule
a/sin A = b/sin B
In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet.
Hence:
HI/∠J = JH/∠H
= 8/sin 90° = 1.9/sin ∠H
Cross Multiply
∠H = arc sin(sin 1.9 × 90/8)
∠H = 21.9°
Answer:
Step-by-step explanation:
let the first angle be 5x
second be 4x
and third be 1x
as we know that by adding all the sides of triangle we get 180°
therefore ,
5x+4x+1x=180°
10x=180°
hence ,
x=18°
first angle - 18*5 = 90°
second angle - 18*4=72°
third angle - 18°
