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
Search up 0.60 x 312= 187.2, 187.2 + 312 = 499.2
Answer:
126
Step-by-step explanation:
To solve this, we need to use PEMDAS: Parentheses, exponents, multiplication, division, addition, subtraction
((4 x 8) + 10) x 3
Parentheses - multiplication
(32 + 10) x 3
Parentheses - addition
42 x 3
multiplication
126
C) 3, 4, 5
any triangle with that ratio will make a right triangle
It would be $1,800
You would use the distributive property to do 18x5 and then 20x5 and then add those to get 1,800
