A circle has full round angle of 360 degrees. A circle represents all survey participants. We need to find the total number of survey participants.
total = 174 + 122 + 55 + 19 + 130
total = 500
Then determine the measure of angle represents people selected football using information above.
football =

football =

football =

football =

football = 87.84⁰
to the nearest whole number
football = 88⁰
The measure of angle represents people selected football is 88⁰ (b)
12x=4(x+5) (multiplying 4 by each argument in the parenhesis)
12x=4x+20 /-4x both sides
8x=20 /:8 divide both sides by 8

15x-3(3x+4)=6 (-3 times each argument in the parenthesis)
15x-9x-12=6
6x-12=6 /+12 both sides
6x=18 /:6 divide both sides by 6
x=3
3x-5x+10=36
-2x+10=36 /-10 both sides
-2x=26 /:(-2) divide both sides by -2
x=-13
2(x+3)=x+10
2x+6=x+10 /-x
x+6=10 /-6
x=4
Answer:
this means to add 52 to 20 and the answer is 72
eg if you have 52 oranges and you do not eat any and I give you 20 and you add it to the 52 you have,you will have 72
0.4 I think sorry if it’s wrong
Answer:
%12.5
Step-by-step explanation:
<em>Step 1: Make an equation</em>
<em>400x = 450</em>
<u>Step 2: Divide both sides by 400</u>
400x / 400 = 450 / 400
<em>x = 1.125</em>
<u>Step 3: Convert into a percentage</u>
1.125 * 100
<em>%112.5</em>
<em>The increase is %12.5</em>
Answer: %12.5
