Answer:
25
Step-by-step explanation:
If Olivia had 10 more p than Sophia, then Olivia has 35, and Sophia has 25.
35 + 25 = 60!
Answer:
x/28=-4
x=-4*28
x=-112
Step-by-step explanation:
Multiplying both sides of this equation by 3, to eliminate the fraction, we get:
9 + m = 6.
Next, we subtract 9 from both sides to isolate m: m = 6 - 9 = -3
Then m = -3.
Check: Subst. -3 for m in this equation:
9 - 3 6
------- = ------ = 2 (as expected). Thus, m = -3 is correct.
3 3
Problem #10:
4n - 9 = -9 Add 9 to both sides: 4n = -9 + 9 = 0.
Divide both sides by 4: n = 0.
Check: Substitute 0 for n: 4(0) - 9 = -9 is true.
Answer:
? =64.62306
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adjacent side / hypotenuse
cos ? = 3/7
Taking the inverse cos of each side
cos ^-1 ( cos ? ) = cos ^-1 (3/7)
? =64.62306
