Step-by-step explanation:
3x+2y=2------------1
-3x+5y=5-----------2
adding 1 and 2 we get
7y=7
y=1
and from (1),we get
3x+2×1=2
3x=0
x=0 is the required value of x.
Answer:
It should be 324.

Answer:
550g
Step-by-step explanation:
total g in 1 kg is 1000
so 1000 - 550 =450
Answer:
5956 ft
Step-by-step explanation:
If we designate the points at the bases of the skyscrapers as A and B, and the top of skyscraper B as point T, then triangle ABT is a right triangle with angle B = 90° and angle A = 13.7°.
The definition of the tangent function tells us ...
tan(A) = BT/AB
Solving for AB, we find ...
AB = BT/tan(A) = (1452 ft)/tan(13.7°)
AB ≈ 5956 ft
The skyscrapers are about 5956 feet apart.
Answer:
24 sq. m
Step-by-step explanation:
its not a rectangle so you cant just do height x base you have to make it a triangle and a rectangle
4x5 = 20 sq m for rectangle
1/2 x 4 x 2 = 4 sq m for the triangle
20 + 4 = 24sq m
