Answer: $80
Step-by-step explanation:
Let the original price of the refrigerator be represented by y.
We are told that an appliance store reduced the price of a refrigerator by 20%. This will be:
= y - (20% of y)
= y - (20/100 × y)
= y - (0.2 × y)
= y - 0.2y
= 0.8y
We are then told that the store then raised the prices by 10% from the lower price. This will be:
= 0.8y + (10% of 0.8y)
= 0.8y + (0.1 × 0.8y)
= 0.8y + 0.08y
= 0.88y
Since we told that now the price was $70.49, this means that we have to find the value of y using the above expression. This will be:
0.88y = $70.49
y = $70.49/0.88
y = $80.10
y = $80 approximately
The original price of the refrigerator is $80.
If you arrange this properly in the slope intercept form (y=mx+b) so just make it arranged in this format.
4x-7y=-28
Subtract 4x
-7y=-28-4x
Rearrange.
-7y=-4x-28
Divide by -7
y=4/7x+28
The number next to x is your slope and the other number is your y-intercept.
5(2x + 5), because 10x and 25 only have 5 in common, which is why it's outside the bracket, and 5 × 2x is 10x, and 5 × 5 is 25. Hope this helps!
3/5 of a gallon or .06
Explanation:
To solve you need to divide the three gallons of paint by the 5 cans. This can be solved in two ways.
Way 1 (fraction)
This is the easiest way, you simply put the first number in the equation on top and the second on the bottom, then simplify if possible. When we do this we get 3/5 and it can’t be simplified so we leave it as the fraction three fifths of 3/5.
Way 2 (decimal)
This way you divide 3 by 5, you can use long division to do this but it takes a long time. The answer is 0.6.
I hope this helps. Please mark me the Brainliest, it’s not necessary but I put time and effort into every answer and I would appreciate it greatly. Have a great day, stay safe and stay healthy ! :)
Answer:
9 (10+3)
Step-by-step explanation:
90 = 9*10 = 9*5*2
27 = 9*3
The greatest common factor is 9
