Step-by-step explanation:
step 1: 25+5=30
step 2: 30-8=22
step 3:22-7=15
Answer:
65 units
Step-by-step explanation:
Let the length of the perpendicular dropped from the right angle to the hypotenuse be h units.
Now by geometric mean property:
Fraction means a part of something
we see
18 times a fraction is bigger or smaller or equal to 18
18 times a fraction means take a part ouf of 18
in this case
18 times 4/5=72/5=14.4
14.4 is less than 18
when you take a fraction of something, it becomes smaller, like if you take a slice of pizza or a fraction of the pizza, it becomes smaller

Answer:
30 minutes
Step-by-step explanation:
We can use ratios to solve
2 miles 5 miles
------------ = -------------
12 minutes x minutes
Using cross products
2 *x = 12*5
2x = 60
Divide by 2
2x/2 = 60/2
x = 30 minutes
Answer:
n = -14
Step-by-step explanation:
Let us try to solve this equation for n;
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 + n
3x - 3x -8 - 6 = n
-14 = n
The value of n = -14
This value is the value of the equation that will have no solution.
To know if we are correct, let us input this value into the expression
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 -14
Collect like terms;
3x - 3x = 8 + 6 - 14
0 = 0
