Answer:
66
Step-by-step explanation:
you find the difference of 114 and 48 then thats youre third angle
Answer:
Step-by-step explanation:
480 because you multipy 4 times 8 and than you mulpyy 48 times 10 and that is how i got the number 480.
3x + 5y = -2
3x + 7y = 26
Subtract first equation from second
2y = 28
y = 14
Plug it in
x = -24
1. 1/3 - 7/8
rewrite the complex fraction as a division expression
show the complex fraction in simplest form.
step 1
we have
Multiply the first term by 8/8
so
(1/3)*(8/8)=8/24
Multiply the second term by 3/3
(7/8)*(3/3)=21/24
step 2
substitute in the original expression
8/24 -21/24
the fractions have the same denominator
so
(8-21)/24
-13/24
therefore
the answer is
-13/24
Answer:
1) The answer is in decimal since 82.8 is not a square number and does not have a proper square root. And the nearest square number to it is 81 whose root is 9 and the upcoming square number is 100 whose root is 10. So the root of 82.8 will be decimal and between 9 and 10.
2) a^2 + b^2 = c^2
14^2 + 10^2 = c^2
196 + 100 = c^2
296=c^2
root of 296 is 17.2
So, x=17.2
Here also the answer is in decimal since it is not a square number. The nearest square number to 296 is 289 whose square root is 17 and the next square number after 296 is 324 whose root is 18. So the square root of 296 will be in between 17 and 18.
