Answer:
58
Step-by-step explanation:
A easy way to get this is to remove the decimal in 5.8 which gives you ----> 58
NOTE: This works for any problem multiplying 10 x a decimal.
Answer: He is Incorrect, It's 38
Work: For this question, I did the Cross-Product Method. The Cross Product Method is when you solve equation via to fractions. With the CPM, One one side of the fraction, I had x / 20 (Twenty being the whole number) and on the other side, I had 190/100 (190 being the percent) After setting this up, I made the equation. 190 times 20 is 3800, and the other multiplication is 100 times x which is 100x. So, the new equation is 3800 = 100x. I divided both sides by 100, and the answer is 38 = x

Answer:
Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.
Answer:
3=2n
Step-by-step explanation:
Formula: Tn=T1+(n-1)*d
Tn is the nth term
T1 is the first number of the sequence
n is the nth term as well
D is the common difference
now its Tn=5+(n-1)*2
now solve that so its
Tn=5+2n-2
now its
Tn=3+2n
that's it
The answer is -183 because the negative is the biggest number so it stays negative
