Answer:
100 is inital value of that decrease
Answer:
12
Step-by-step explanation:
These triangles are similar using the AA theroem. This means there sides are in corresponding proportion.
Side AR and Side TE are corresponding. Use this proportion.
This side the triangle SAR side lengths are 3/4 of side lengths of triangle SET.
We know that RS+ST=21
And that RS=3/4(ST).
x=12.
Side ST is 12
notice |7| 7 is positive, so we can simply remove the bars and use 7 by itself
Answer:
40x = 1800 +25x
Step-by-step explanation:
Answer:
½ and 14/28
Step-by-step explanation:
If a pair of ratio forms a proportion, they are equal.
First pair of ratios:
4/5 =10/13
Convert to the least common denominator (4 × 13)/65 = (10 × 5)/65
52/65 ≠ 50/65
The first pair of ratios is <em>not</em> a proportion.
Second pair of ratios:
7/8 =15/18
Convert to the least common denominator (7 × 9)/72 = (15 × 4)/72
63/72 ≠ 60/72
The second pair of ratios is <em>not</em> a proportion.
<em>Third pair of ratios:
</em>
½ =14/28
Convert to the least common denominator (1 ×14)/28 = 14/28
14/28 = 14/28
½ = 14/28
½ and 14/28 form a proportion.
