Answer:
In step 2, he needed to divide both sides of the equation by 5
Step-by-step explanation:
we have

Solve for a------> That means isolate the variable "a"
step 1
Subtract 2b to both sides


step 2
Divide by 5 both sides


Answer:
$626
Step-by-step explanation:
450.25+175.75=626
He had put in $300 and got out $336 at the end of the year.
This means an increase of $36 over a year.
10% of $300 = $30 dollars
This shows that he definitely got more than a 10% increase.
Alan got $6 more than $30 so to find 6 from 30, you divide by 5
so ( 10% = $30 ) divided by 5 = ( 2% = $6 )
Adding the amount of money and percentages gives you 12% = $36
So the amount of mpercentage increase is 12%
Overall the amount of money in his bank now compared to when he deposited it, he has 112% in the bank.
Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
Answer:
y = 28x
Step-by-step explanation:
To find the answer, we need to divide the number of bushels by the number of acres. If the quotient is the same for all three divisions, then the quotient is how many times x is multiplied to get y.
140 / 5 = 28
224 / 8 = 28
420 / 15 = 28
Therefore, y = 28x is our answer.
