In equations you must do the same to both sides so that the equation stays equal. also, it's easier to solve if you get the unknowns on one side.
so first you distribute
-7(x-4) means (-7 times x) + (-7 times -4) so -7x+28
-7x+28+8x=12+14
add like terms
x+28=26
subtract 28 from both sides
x=-2
1/4. and. 1/12. will do that.
There are 53 of each type of fish in the pond, hope this helps :3
Answer:
17) 53.2
18) 17
Step-by-step explanation:
In similar triangles theorem, the ratio of the corresponding sides of two triangles are equal.
17) To determine x, ratio of the sides of 1st triangle/Ratio of the sides of 2nd triangle.
Ratio of base to the missing side:
7.6/x = 13.6/95.2
7.6/x = 13.6/95.2
7.6/x = 0.1428
7.6= 0.1429x
x = 53.2
18) ratio of shortest side/ longest side
3.4/7.9 = x/39.5
x = 3.4/7.9 × 39.5
x = 17
