26. Answer 44

6x + 11 = 10x - 9

subtract 11 and 10 from both sides to get
-4x = -20 then divide that by negative 4 whicg will get you x=5 then plug in
6(5)+11=44

27. Answer 18

9x-4=158 since bisect means cut into 2 equal pieces so abd and dbc equal 79, add 4 to get 162 then divide by 9 to get x=18

29. Answer 28

2h+6+h=90

(____)
this part represents G
complementary angles are two angles that add up to 90, so subtract 6 from 90 and add the variables to get 3h=84 then divide by 3

H = 28 to check you can plug 28 into the equation

ECD=90 ECD=x+5+3x-7=4x-2, 4x-2=90, 4x=92, 4x/4=92/4, x=23
a) 23
ECH=x+5, 23+5=28, ECH=28
b)28
HCD=3x-7, 3(23)-7, 69-7=62 HCD=62
c)62
GCF & ECH are vertical angles, GCF=28
d) 28
ECF=180, 180-28(GCF)=152, ECF=152
e) 152
DCF=90, 90+28(GCF)=118
f) 118

Miss Hernandez has $100 to spend on parking and admission to the zoo the parking will cost $7 and Mission tickets will cost 1550
Mandarinka [93]
It should say $15.50. Parking = p. n = number of people.

n15.50 + 7 is the equation.

She can bring 6 people, because (6 * 15.50) + 7 = $100

At the movie theatre, child admission is $5.10 and adult admission is $9.70. On Thursday, 128 tickets were sold for a total sale
kvv77 [185]

Answer:

53

Step-by-step explanation:

Let x be the number of children tickets sold and y be the number of adult tickets sold. Then

x+y=128.

The cost of x children tickets is $5.10x and the cost of y adult tickets is $9.70y, so

5.10x+9.70y =896.60.

From the first equation,

x=128-y,

then

5.10(128-y)+9.70y=896.60,\\ \\652.80-5.10y+9.70y=896.60,\\ \\4.60y=243.8,\\ \\y=53.

53 adult tickets were sold.

D) Vivek is 30 years younger than his father. After 10 years their ages will be in the ratio 1:2. Find their present ages.​
tangare [24]

Answer:

I think Vivek is 20 and his father is 50

Because 30 + 30 equals 60 as he has to be half his age he'll be 30 but that's in 10 years time. you just subtract 30 and 60 by 10 and you'll get 20 and 50
