The average attendance of Everton football club fell by 7% in 1982. If 2030 fewer people went to matches in 1982, how may went in 1981?

29000  people went in 1981.

Step-by-step explanation:

Let  x= Attendance in 1981.

Given: The average attendance of Everton football club fell by 7% in 1982.

Difference in attendance from 1981 to 1982 =  0.07x

If 2030 fewer people went to matches in 1982,

Hence, 29000  people went in 1981.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
