Answer:
m∠1 = 81
m∠2 = 99
Step-by-step explanation:
The angles are supplemaentary and therefor sum to 180
3x + (x + 72) = 180
4x + 72 = 180
4x = 108
x = 27
m∠1 = 3x
m∠1 = 27(3)
m∠1 = 81
m∠2 = x + 72
m∠2 = 27 + 72
m∠2 = 99
Answer:
2a + 8√b
Step-by-step explanation:
√9a² = 3a
√49b = 7√b
and
3a + 7√b - a + √b = 2a + 8√b
i would say the answer is 5/8
because c is 3/4
Let's do it step by step:
"three-fifths of a" would be 3/5 multiplied by a, as that is how you find fractions of numbers, so we can write that as (3/5)a
"7 less" means we have to subtract 7 from (3/5)a, so we get (3/5)a - 7
Now all we need to do is make it equal to B, so your final answer is
(3/5)a - 7 = b
I hope this helps! I put the 3/5 in brackets just so you didn't mistake it as 3/(5a) :)
