Answer:
x > 2
y ≥ 2
x + y ≤ 8
Step-by-step explanation:
Here, we want to write a system of equations according to the given variables
More than means, greater than
since x is the variable we want to use;
x > 2
At least 2 hours means greater than or equal to 2
That is mathematically represented as;
y ≥ 2
At most means less than or equal to
So;
x + y ≤ 8
Item 7 Question 1 Select the equation that represents the question. What percent of 300 is 51? 300=51×p 51=p×300 300=p×51 p=300×51 Question 2 Solve the equation. P= %
Answer:
51 = p×300
p = 17%
Step-by-step explanation:
Let p be the value of the percentage.
To find the percentage;
51/300 = p
51 = p * 300
Therefore, p = 0.17
Percentage represents a 100;
P = 0.17 * 100
P = 17%

Determine the value of x.
Answer:
x = 10
Step-by-step explanation:
Every triangle has 180o. Just add the three angles together.
8x + 5 + 3x + 25 + 4x = 180 Combine the like terms.
15x + 30 = 180 Subtract 30 from both sides
15x = 180 - 30 Combine
15x = 150 Divide by 15
x = 150/15
x = 10
Answer:
10
Step-by-step explanation:
8x + 5° + 3x + 25° + 4x = 180° (angle sum property of a triangle)
8x + 3x + 4x + 5° + 25° = 180°
15x + 30° = 180°
15x = 180° - 30°
15x = 150°
x = 150/15
x = 10°

Last year 858 people attended the Middleton County Fair. This year 1,635 people attended. What was the percent increase from last year to this year? (Round to the nearest percent)
Answer:
91%
Step-by-step explanation:
The first step is to calculate the increase
= 1635-858
= 777
Therefore the percent increase can be calculated as follows
= 777/858 × 100
= 0.905× 100
= 90.5 %
= 91%
Hence the percentage increase is 91%

An architect designs two similar triangular patios. The first patio has angle measures of (x − 10)°, (y + 25)°, and 60°. The second patio has angle measures of (x – 5)°, 55°, and 65°. Find the values of x and y.
Answer:x=65 y=40
Step-by-step explanation:
1) solve for x in the second triangle by adding each degree together and setting it equal to 180 (every triangle equals 180°)
2) x should equal 65
3) do the same for the first triangle except plug in 65 (since we know it equals x) and solve for y.

Last year, Amy opened an investment account with $6800. At the end of the year, the amount in the account had increased by 23.5%. How much is this increase in dollars? How much money was in her account at the end of last year?
Answer:
-The increase in dollars is $1598
-The amount in her account at the end of last year was $8398.
Step-by-step explanation:
To find the increase, you have to multiply the initial amount for the percentage increase:
6800*23.5%=1598
Now, to find the amount in her account at the end of last year, you have to add the initial amount plus the increase in dollars:
6800+1598=8398
According to this, the amount in her account at the end of last year was $8398.
Between them Molly and Sue have 32 marbles. Molly has 3 times as many as Sue. How many marbles does each girl have?
Answer:
Sue has 8 marbles
Molly has 8 marbles
Step-by-step explanation:
m = number of marbles Molly has
s = number of marbles that sue has
m+s =32
m = 3s
Substitute the second equation into the first equation
3s+s =32
4s = 32
Divide by 4
4s/4 =32/4
s = 8
Sue has 8 marbles
m = 32 = 3*8 = 24
Molly has 8 marbles

What are the zeroes of the function?
y = (x – 3)(x + 2)(x – 2)
A. –3, 2, –2
B. –3, 2, 2
C. 3, –2, 2
D. 3, 2, 2
Answer:
Option C
Step-by-step explanation:
x - 3 = 0
Add 3 to both sides;
x = 3
x + 2 = 0
Subtract 2 from both sides;
x = -2
x - 2 = 0
Add 2 to both sides;
x = 2

Nadia is a stockbroker. She earns 13% commission each week. Last week, she sold $4,500 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?
Multiply amount sold by commission rate:
4500 x 0.13 = 585
She made $585 last week.
Multiply amount made in 1 week by 52 weeks ( 1 year = 52 weeks)
585 x 52 = 30,420
She made $30,420 in 2011

A model car is 12 inches
long. Using a scale of
3inches : 4 feet, how long
is the actual car?
A. 1 foot
B. 9 feet
C. 16 feet
Answer: C
Step-by-step explanation: If a car is 12 inches a room could possibly be 16 feet and a room and a car might or if not might have the same width
I hoped i helped :)
Answer: C) 16 feet
=======================================================
Work Shown:
3 inches on paper = 4 feet in real life
Multiply both sides by 4 so that the "3 inches on paper" turns into "12 inches on paper"
We get
4*(3 inches on paper) = 4*(4 feet in real life)
12 inches inches on paper = 16 feet in real life
This leads to the answer C) 16 feet.
--------------------------
Alternative Method:
(3 in on paper)/(4 ft in real life) = (12 in on paper)/(x ft in real life)
3/4 = 12/x
3*x = 4*12 ... cross multiply
3x = 48
x = 48/3 .... dividing both sides by 16
x = 16
The car's length is 16 feet in real life.
