Answer:
a = -25
Step-by-step explanation: a+ 52/3 =9
multiply both sides by 3
3(a+52)/3 = 9.3
Simplify
a+52=27
Subtract 52 from both sides
a+52-52=27-52
Simplify
a= -25
Answer:
Step-by-step explanation:
132 + (4x - 10) + (5x - 11) + 128 + (4x+2) = 540 All convex 5 sided figures have 540 degrees. Remove the brackets.
132+ 4x - 10 + 5x - 11 + 128 +4x + 2 = 540 Collect like terms
13x + 241 = 540 Subtract 241 from both sides.
13x = 540 - 241
13x = 299 Divide by 13
x = 299/13
x = 23
<P = 4x + 2
<P = 92 + 2
<P = 94
From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
Answer:
10.56
Step-by-step explanation:
According to figure,
taking angle 26° as reference angle,we have
h=24
p=x(?)
Now,
sin 26°=p/h
sin 26°=x/24
0.44=x/24
0.44×24=x
x=10.56
97 rounded to the nearest tenth is 100.
