There is no work. i just did it in my head. x = 15 because 15^2 equals 225 and 15+2 = 17 so if 15*15 equals 225 then if you add 30 more that is 255. 30 is equal 2*15 and so you could also say 15*15+(15*2) so 15*17 = 255 so x = 15. you're welcome.
Answer:
d = 9/10
Step-by-step explanation:
Hi,
d divided by 5/6 = 3/4
You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.
d ÷ 5/6 = 3/4
Multiply both sides by 6/5 (remember to flip)
d = 3/4 x 6/5
(when multiplying fractions, you can multiply straight across)
d = 18/20
(simplify - both numbers can be divided by 2)
d = 9/10
Hope this helps :)
Answer:
x = 5.25
y = 7.5
Step-by-step explanation:
Since line 1.5 is parallel to line x which is parallel to line y
then 2/(2+5) = 1.5/x
2x = 7(1.5)
2x = 10.5
x = 5.25
Similarly, 2/(2 + 5 + 3) = 1.5/y
2y = 10(1.5)
2y = 15
y = 7.5
I'm taking the liberty of editing your function as follows: <span>w=4r^2+6s^2, where I use " ^ " to indicate exponentiation.
The partial of w with respect to r is 8r. That with respect to s is 12s.</span>
Answer:
m<2= 48
m<3= 52
m<4= 48
Step-by-step explanation:
the opposite of 1 is 3 so 3 is 52 bc opposite angles have the same degree
to find angle 4 you subtract 90 by 52 bc 90 is the total for angle 1 and 4
to find angle 2. u find the opposite of it which is 42 and like i said opposite angles have the same degree
hope this helps
