Answer:
4√2 and 5+4√2
Step-by-step explanation:
Let the two numbers be x ad y
Smaller = y
Bigger = x
If a positive real number is 5 more than another, then;
x = 5 + y ... 1
When - 10 times the smaller is added to the square of the larger, the result is 57, then;
-10y + x² = 57 ...2
Substitute 1 into 2;
-10y + (5+y)² = 57
-10y + 25+10y+y² = 57
y²+25 = 57
y² = 57 - 25
y² = 32
y = √32
y = 4√2
Since x = 5 + y
x = 5 + 4√2
Hence rhe numbers are 4√2 and 5+4√2
Answer:
Part A:
Luke's original box of cereal costs $2 more than the super-saving brand.
y=9(1)
y=9
11-9=2
Part B:
y=9(6)
y=54
11x6=66
66-54=12
Luke saves $12 each month if he buys 6 boxes of the super-saving brand.

Answer:
( B.) 6, 1, -2 , -4
Step-by-step explanation:
A coefficient is a number multiplied by a variable. So, in this case let's take a look at the problem.
-2+6y+m-2y+8-4m
Now we have to find the numbers that have a variable next to it
which are 6,m,-2, and -4
(If you are wondering that why m is a coefficient its because it is also known as 1m)
Final answer = 6, 1, -2 , -4

Answer: 55% are girls,45% are boys, number of girls is 122% of the boys,number of boys is 81.8%
Step-by-step explanation: percentage of girls = number of girls ÷ total population × 100
= (198/360)× 100 = 55%
Number of boys = 360 -198 = 162
Percentage of boys = (162/360) × 100 = 45%
Percentage of girls to boys = (198/162) × 100 = 122%
Percentage of boys to girls = (162/198) × 100 = 81.8%
