Kate: 1250 ≥ 525+25x
25x ≥1250 -525
25x ≥ 725
x ≥ 725 / 25
x≥ 29 weeks
Rebecca: 1350 ≥ 510 + 30x
30x ≥ 1350 - 510
30x≥ 840
x≥ 840 / 30
x≥28 weeks
Katie needs 1 more week than Rebecca
46.6 billion
explanation:
Isolate S on the left side by adding 1.9x to both sides. this gives you S = 4.8 + 1.9x. Plug in 22 for x because 2020 is 22 years from 1998.
4.8 + 1.9(22) = 46.6
Answer:
see the explanation
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional (this ratio is called the scale factor) and its corresponding angles are congruent
therefore
Two triangles are similar if there is a correspondence between their angles and their sides so that all corresponding angles are <u><em>congruent </em></u> and all corresponding sides are <u><em>proportional</em></u>
You were really close :D
The mistake you made is that 44 - 36 is 8, not 6.
Using 8 instead, the answer is:
