We will solve the problem for both cases:
Case 1:
If the amount increases by 7% we have the number for which we are going to multiply is given by:
Case 2:
If the amount decreases by 7% we have the number for which we are going to multiply is given by:
Answer:
single multiplier you would use for each case is:
x = 1.07 (increase)
x = 0.93 (decrease)
So you have 10 marbles all together. you remove one and dont replace it. it will be 3/9 which simplifies to 1/3.
Answer:
= 10x+35
Step-by-step explanation:
(5)(2x+7)
(5)(2x)+(5)(7)
=10x+35
Answer:
What's d question It all letters
Answer:
2:3 unless it wants it in total, then 220:330
Step-by-step explanation:
it gives you the answer with the fraction. A ratio is basically saying with x:y for every x number of one thing there are y number of another. In this case we know 2/5 will be green, so how many will be red? 3/5. So for every 2 greens there are 3 reds.
Another way of looking at it is for the totals. there are 550 total, so 2/5 of that is green. 2/5 of 550 is 220, while 3/5 is 330 so that means of the 550, the ratio is 220:330. Kinda like simplifying fractions where 220/550 is the same thing as 2/5
