Answer:
Sarah is incorrect.
Step-by-step explanation:
By plugging 10 in as 'x' to the equation, we get y=21+(2*10). 2 x 10 is 20, and 20 + 21 is <em>not</em> 42 - it's 41. So, Sarah is incorrect.
Answer:
24
Step-by-step explanation:
the question translates to asking how many times does 7/8 fit in 21, so 21 divided by 7/8.
when we divide by a fraction, we can multiply by it's inverse, so 21 divided by 7/8, is 21 multiplied by 8/7. so:
21×8/7 = (21×8)/7 = (21/7)×8 = 3×8 = 24
Answer:
the answer would be $45.55
<3
Step-by-step explanation:
20$ + $50.00 = $70
$70 - $6.95 = $64.5
$64.5 - $9.95 = $54.55
$54.55 - $20 = $34.55
$34.55 + $15 = $49.55
$49.55 - $4 = $45.55
