Answer:
Step-by-step explanation:
It has to be less than 6 , x+y<6
Now in inequalities that have 7 and 5 in them, 7 represents the cost of first ingredient and 5 the cost of second ingredient.multiply each of that number with quantity of that ingredient and sum both up we get the price of the mixture.
the mixture has to be less than 30 that means that it costs less than 30 but 30 can be the answer as well.
The last answer is 7x + 5y
Answer:
Step-by-step explanation :
Let x be the number.
x × 8/100 =48
x =48 × 100/8
Now cut 48 by 8 and we get 6.
x = 6 ×100
x =600
So 600 is the required number.
Answer: P=47 inches
Step-by-step explanation:
First, you have to find the other side lengths. Two of the sides are equal to 20 because this is a rectangle. The first blank would be 20 because 20 times the other side length is equal to 70. Then you would divide 70 by 20 which would equal x. x would equal 3.5 in. Then the perimeter would be:
2(20)+2(3.5)=P
P=47 inches
Answer:
x=−0.433107,3.352224
Rounding up should be -0.4 and 3.4
Step-by-step explanation:
Answer:
42%
Step-by-step explanation:
The first step is to calculate the difference in the number of fishes from the beginning of the day to the end of the day.
90 -52
= 38 fishes
Therefore the percent decrease can be calculated as follows
= 38/90 × 100
= 0.422 × 100
= 42.2 %
= 42% ( to the nearest cent)
