We are given a figure with several given expressions:
EK = x + 5
KJ = x +5
FG = 2x
GH = 3x - 5
Assuming that the triangle is equilateral:
equate GH = FG
3x - 5 = 2x
solve for x
x = 5
therefore, one side of the triangle:
x + 5 + x + 5 = 20
and the perimeter of the equilateral triangle is
3*one side = 3 * 20 units
Thus, Perimeter = 60 units. <span />
Answer:
(8, 11 )
Step-by-step explanation:
Given the 2 equations
2x + 2y = 38 → (1)
y = x + 3 → (2)
Substitute y = x + 3 into (1)
2x + 2(x + 3) = 38 ← distribute and simplify left side
2x + 2x + 6 = 38
4x + 6 = 38 ( subtract 6 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Substitute x = 8 into (2) for corresponding value of y
y = 8 + 3 = 11
Solution is (8, 11 )
Answer:
X=16*7/8= 14. by multiplying. 16 *7/8
(j+5)*8 is what you're looking for. The braces are important.
You could also write as 8j + 40.
