4/6, 12/15, 8/12 are some of the expressions
Answer:11+8t
Step-by-step explanation:
the first two numbers don't have variables but the second two numbers have so basically you just have to do what the sing tells you to do 'subtract' and keep you variable 't' and of course add 3 and 8
Answer:
a = -8
Step-by-step explanation:
-5⁄2 a + 5 = 25
Subtract 5 from each side
-5⁄2 a + 5-5 = 25-5
-5/2 a = 20
Multiply each side by -2/5 to isolate a
-2/5 * -5/2 a = -2/5 *20
a = -8
Answer:
D. 13.267 m
Step-by-step explanation:
We can use the Pythagorean theorem to solve this problem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
7^2 + b^2 = 15^2
49 + b^2 = 225
Subtract 49 from each side
b^2 = 225-49
b^2 =176
Take the square root of each side
sqrt(b^2) = sqrt(176)
b = sqrt(176)
b = 13.266
Answer:
Yes, because the side lengths would form an isolities triangle.
