Answer:
84 years
Step-by-step explanation:
Given :
At present :
Let :
daughter's age = x
Woman's age = 2x
21 years ago :
Woman's age = 3 times daughter's age
2x - 21 = 3(x - 21)
2x - 21 = 3x - 63
-21 + 63 = 3x - 2x
42 = x
Daughter's age = 42
Woman's age = 2x = 84
Hence, woman's present age is 42 years

A roller coaster has 3 trains with 7 rows per train. Riders stand in rows of 6, for a total of 42 riders per train. The operators of the coaster recorded the number of riders on each train during a run. On the first train, the operators reported that 6 rows were filled. On the second train, all 7 rows were filled. On the third train, 4 rows were filled. How many rows were empty on the first train? How many additional riders would it take to fill those empty rows?
Answer:
a. 1 row
b. 6 people
Step-by-step explanation:
a. Each train has 7 rows yet the first train only had 6 rows filled up. This means that:
= 7 - 6
= 1 row was empty
b. Riders stand in rows of 6 which means that one row has 6 people. With only 1 row empty, the number of people needed will be:
= 6 people

Flagship Cinemas sells movie tickets that are $4 for matinees and $7 for regular shows. One night the theater sells 578 tickets and collects $3365 in total ticket sales. Whích system best represents the situation?
Answer:
4x + 7y = 3365
x + y = 578
x = matinees
y = regular
Step-by-step explanation:
Given
$4 = matinees
$7 = regular
Total tickets = 578
Money collected = $3365
If one calls the amount of matinees that when "x" and the amount of regulars that went "y", then one can form the system;
4x + 7y = 3365
x + y = 578
Solving the system;
Multiply the second equation by (-4)
4x + 7y = 3365
-4x - 4y = -2312
Add the equations
4x + 7y = 3365
-4x -4y = -2312
3y = 1053
Inverse operations
3y = 1053
/3 /3
y = 351
x = 227

(b) Carlotta thinks that [tex]3y + 5y^3[/tex] is the same as [tex]8y^4[/tex]. Which statement shows that it is NOT the same?
Answer:
[tex](x + y) - (x - y) =2y[/tex]
[tex]3y + 5y^3 \ne 8y^4[/tex]
Step-by-step explanation:
Solving (a):
Given

Required
Simplify
[tex](x + y) - (x - y)[/tex]
Open brackets
[tex](x + y) - (x - y) = x + y - x + y[/tex]

Daniel and Lisa are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. Daniel sold 5 rolls of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $74. Lisa sold 1 roll of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $58. Find the cost each of one roll of plain wrapping paper and one roll of holiday wrapping paper
Answer:
P = 4 & H = 18
Step-by-step explanation:
Daniel : 5 plain paper + 3 holiday paper = 74, 5P + 3H = 74 . Lisa : 1 plain paper + 3 holiday paper = 58, P + 3H = 58 . Solving two equations, P = 4 & H = 18
pls help me with this problem!!!!
Answer: 55°
Step-by-step explanation:
∠YAZ + ∠YAX = 180° because they are linear pairs
∠YAZ + ∠YAX = 180°
∠YAZ + 125 = 180
Subtract both sides by 125
∠YAZ = 55°
