I got X=11
Minus 7x on both sides
The equation the becomes :
-2x +179=157
Subtract 179 from both sides
Equation now is:
-2x= -22
Divide -2 on both sides
X= 11
Answer
the first one is 2/3 and the second is 1/4 the other i'll comment a little later
Step-by-step explanation:
H = 27 m. Since these are scales of each other, you can solve for h by creating a ratio of the two lengths. Divide 36 by 4 to find the scale for the tree. 36/4 = 9. This means that the large triangle is 9 times larger than the small one. Now to find h, multiply the height of the small triangle by the scale. 3 x 9 = 27. This means the height, h, of the large triangle is 27 m. You can check this by dividing the length of each triangle by their height. If they are the same number, the scale is correct. 36/27 = 1.33, 4/3 = 1.33 ✅

Answer:
x = 3
Step-by-step explanation:
-4x-5+2x = -11
(-4x+2x)-5 = -11
-2x-5 = -11
-2x-5+5 = -11+5
-2x/-2 = -6/-2
x = 3
