Answer:
Step-by-step explanation:
pedometer is out by 0.08 miles
As a percentage of the correct distance, this is 0.08/0.5 = 0.16 or 16%
A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.
To solve this, you will combine like terms first:
-3x-7x < 20
-10x < 20
Divide both sides by -10:
-10x/-10 < 20/-10
When you divide an inequality by a negative number, you flip the inequality symbol:
x > -2
Well, let's multiply them!
8/3 * 9/7 = 72/21
8/3 x 9/4 = 72/12.
We know the one with the smallest denominator is larger if the numerator is the same. So that means
72/12 is larger.
Answer: 5
Step-by-step explanation:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
x^2 = 25
square root both sides
x = 5
to check, do 12^2 + 5^2 =169
sqrt of 169 is 13
hope this helps
Answer:
x =7, y = 3
Step-by-step explanation:
We substitute the value of x in terms of y (given) into the equation.
Then we solve for y and plug in the value of y back into the equation for the value of x to find x.
