So, first, we know that the whole angle must equal 90 because there's a right angle symbol, and right angles equal 90 degrees.
So, 43 + x + 3 must equal 90.
Or, 46 + x = 90
Then subtract 46 from both sides.
x = 90 - 46
x = 44
These would also be adjacent angles because they share the same vertex.
Answer:
Step-by-step explanation:
Area of sector = angle/360 * pi * r^2
5.5pi = angle/360 * pi * 9
5.5 = angle/360 * 9
angle = (5.5 * 360)/9 = 40 * 5.5 = 220
Answer:
30/7
Step-by-step explanation:
Distribute:
-2x-26+9x=4
Combine like terms:
7x-26=4
Add 26.
7x=30
Divide by 7:
x=30/7.
Hope this helps :D
let's set up an equation
4x=24
solve normally:
x=6
so the expression is 4x=24 and she can have 6 kids in each group
Answer:Yes they are equivalent.
Step-by-step explanation:
3/4a + 8 - 1/4a - 2 1/2(a + 12)
Combine like terms Distributive property
2/4a+6 1/2a+6
2/4=1/2 (simplify)
1/2+6=1/2+6
