Answer:
d = 41
Step-by-step explanation:
if the two lines are parallel, then 113 and 2x-5 are supplementary, which means that they add up to 180.
So:
113 + 2x - 5 = 180 =>
2x = 72
x = 36
Next step, we have three angles in the triangle that should add up to 180:
2x-5 + 2x + d = 180 with x=36
d = 180 - 139 = 41
so the angles are 72, 67 and 41
Answer:
Yes
Step-by-step explanation:
To determine if this is a right triangle, use the pythagorean theorem and see if a^2 + b^2 is equal to c^2.
a^2 + b^2 = c^2
12^2 + 16^2 = 20^2
Evaluate the exponents.
144 + 256 = 400
Add them together.
400 = 400
Since a^2 and b^2 add up to equal c^2, this is a right triangle.
Ask yourself f(x) equals X +18 to the second power +12
<span>Tammy rents an apartment close to her school campus. The equation that is given is this one:
r = 355m,
where r is the amount spend on the rent.
m is the number of months.
In order to get the constant proportionality of r to m in this relationship, then we can set a constant k variable.
r = 355 m (k)
k = 1 r / 355 m
1 hour spent, it takes you to spend 355.</span>
Answer:
15
Step-by-step explanation:
Each bracelet takes 28+10 = 38 elastic bands. If you have 600 bands, you can make ...
600/38 = 15 30/38 . . . bracelets
You can make 15 complete bracelets.
__
You will have 30 elastic bands left over.
