Answer:
2.5
Step-by-step explanation:
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)
Answer:
D) x=-3, y=-7
Step-by-step explanation:
9x - 7y = 22
x + 3y= -24
9x - 7y = 22
x= -24-3y
9(-24-3y)-7y=22
x= -24-3y
-216-27y-7y=22
x= -24-3y
-34y=22+216
x= -24-3y
-34y=238
x= -24-3y
y=238/(-34)
x=-24-3y
y=-7
x=-24-3*(-7)
y=-7
x=-24+21
y=-7
x=-3
(x,y)=(-3,-7)
Answer:
C) 9x
Step-by-step explanation:
a term is a single mathematical expression, all the other options are just parts of terms in the expression
Answer:
26,664 inches
Step-by-step explanation:
Set up a proportion to solve this...
33 inches is to 1.25 miles as 'x' inches is to 1,010 miles
33/1.25 = x/1,010 now solve for x by cross multiplying
33,330 = 1.25x
33,330/1.25 = x
26,664 = x
