Answer:
regressive direct proportional
Step-by-step explanation:
Yes. The alg<span>ebraic sum of a negative mixed number and other mixed number.</span>
-1 1/3 + x = 2
<span>x= 2 + 1 1/3 </span>
<span>x = 3 1/3 </span>
So, the algebraic sum: (-1 1/3) + 3 1/3 = 2
So basically you want to find the total percentage of cakes that weren't sponge cakes first.
You already have the 50% of party cakes. For the 1/5 percent of fruit cakes, you can multiply it by 20/20, to get 20/100, and then just take the 20 to get 20% that were fruit cakes.
Now you can just add the percentages together.
50% + 20% = 70%
So now you know 70% weren't sponge cakes, out of 100%.
So here you can just subtract 70% from 100% to figure out the remaining part of 100%, which must be sponge cakes.
100% - 70% = 30%
So 30% of the cakes were sponge cakes.
The first answer would be to take 182.50-67 and it gives you 115.50 which is number one.
2. To solve X/0.4=10 you need to get X by itself since it's being stuck by division you multiply both sides by 0.4 which is the third answer down. Hope this helps!
