- 3
distribute each bracket, multiplying the terms in the bracket by the value outside the bracket.
= 3g + 15 - 3g - 18 → ( collect like terms)
=(3g - 3g) + (15 - 18) = 0 + ( - 3) = - 3
Answer:
x = 15
Step-by-step explanation:
Similar triangles and proportional side lengths.
10/4 = x/6
5/2 = x/6
2x = 5 * 6
2x = 30
x = 15
Answer:
78 : 162 = 13 : 27. These two equalities are examples of proportions (equal ratios); it is as simple as that.
