Answer:
Step-by-step explanation:
first term = a = 352
Common difference = d = second term - first term
= 345 - 352
= (-7)
nth term = a + (n-1)*d
43rd term = 352 + (43-1)*(-7)
= 352 + 42 *(-7)
= 352 - 294
= 58
Answer:
$14
Step-by-step explanation:
x/17.5=20/100, do the butterfly method
17.5x20=350
350/100= 3.5
17.5-3.5=14
Answer:
440
Step-by-step explanation:
55x8. 8x5=40 carry the 4. 8x5=40+4=44 so it is 440
Together they scored:
(3x+2)+(300-2x)=347
x+302=347
x=45
Substituting x:
3*45+2=135+2=137
300-2*45=300-90=210
So Makayla scored a total of 210 points
Hello,
We can not divide by 0.
==> x+4.5≠0
==>x≠-4.5
