Answer: No, she did not study for at least 15 hours.
=======================================================
Explanation:
Fractions are often a pain, so I find it easier to convert to decimal form whenever possible.
1/2 = 0.5
3/4 = 0.75
which lead to,
2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5
4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75
4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5
-----------------------------
We can then rephrase the problem like so:
"She studied 2.5 hours on Monday, 3 hours on Tuesday, 4.75 hours on Wednesday, and 4.5 hours on Thursday"
Add up those decimal values to get:
2.5 + 3 + 4.75 + 4.5 = 14.75
In total, Tammy studied for 14.75 hours, which is equivalent to 14 & 3/4 hours.
This result is smaller than 15, so she did not study for at least 15 hours.
Note: "at least 15" is the same as saying "15 or more".

Answer:
y = 3x - 7
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesAlgebra I
Standard Form: Ax + By = C
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Standard Form: 3x - y = 7
Step 2: Rewrite
Find slope-intercept form
Subtract 3x on both sides: -y = 7 - 3xDivide -1 on both sides: y = 3x - 7Answer:
y = 3x + 7
Step-by-step explanation:
subtract 3x from both sides
multiply both sides by (-1) to get positive numbers
Determine the intercepts of the line.

Jimmy took out a loan for $5,600 to pay for a home repair the bank offered an interest rate of 4.75 % how much interest would she pay after three years???
Answer:
$698
Step-by-step explanation:
Given that :
Principal = $5600
Rate = 4.75%
Time = 3 years
Simple interest = principal * rate * time
Simple interest = $5600 * 0.0475 * 3
simple interest = $798
A batch has 15000 coloured bulbs. 3/5 of the batch are orange in colour & the rest are green . if 1/8 th of the green bulbs are not working , how many green bulbs are functional?
Answer:
5250 bulbs are functional green bulbs
Step-by-step explanation:
find out how much 1/5 of 15000 is
15000/5=3000
find out how many are orange
3/5=1/5+1/5+1/5 3000*3=9000
of the 15000 bulbs 9000 are orange the rest are green find the amount that is left over
15000-9000=6000 bulbs are green
find out what 1/8 of the green bulbs is
6000/8=750
1/8 or 750 green bulbs are not working
find out how many bulbs are functional
6000-750=5250 bulbs are functional green bulbs

The sum of the exterior angles in any convex polygon, including a regular 15-gon, is 360∘.
Step-by-step explanation:
thank me later
mark me as brainliest please
Answer:
5 exterior angles.
Step-by-step explanation: since they all have to add to 360 you can divide 360/5 = 72. You can also check by adding one interior angle plus 72 and checking if you get 180.

Equality PropertiesSolving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y = 3x - 3
y = -4x + 4
Step 2: Solve for x
Substitution
Substitute in y: 3x - 3 = -4x + 4Isolate x terms: 7x - 3 = 4Isolate x term: 7x = 7Isolate x: x = 1Here we see that our x-value would equal 1.
∴ (-3, 0) is NOT a solution to the systems.

Step-by-step explanation:
|| represents the absolute value function:
|x| = x when x >= 0,
|x| = -x when x < 0.
Therefore (-8) * |2| = (-8) * 2 = -16. (A)
Answer:
Step-by-step explanation:
In step 1: mode will be solved so |2| will be absolute positive value of 2 which is 2
Step 2: multiply by -8 which is -16
So Answer is (A) -16
Consider the system of inequalities.
3x + 2y < 8
-5x - 9y > -2

(-1, 5)
(0, 0)
d)
(1, -1)
Answer:
b)
The point is (-1,5) and (0,0) also satisfies the given inequalities
The solution of the given inequalities
(x, y) = (4 , -2 )
Step-by-step explanation:
Step(i):-
Given system of equations are
3x + 2y < 8
-5x - 9y > -2
The solution of the given equations are
3x + 2y = 8 multiply '5'
-5x - 9y = -2 multiply '3'
15 x + 10 y = 40 ...(i)
-15x - 27 y = -6.....(ii)
Adding (i) and (ii) , we get
- 17 y = 34
y = -2
Substitute y = -2 in equation 3x + 2y =8
3x - 4 =8
3x = 12
x =4
The solution of the given system of inequalities
(x, y) = (4 , -2 )
Step(ii):-
3x + 2y < 8
-5x - 9y > -2
The point is (-1,5)
-3 + 10 < 8
7 < 8
5 - 45 > -2
-40 > -2
The point (0,0) also satisfies the given inequalities
Final answer :-
The point is (-1,5) and (0,0) also satisfies the given inequalities
Jada traveled 135 miles in 3 hours. Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed. A) How far did Jada travel in 1 hour?
Given:
Jada traveled 135 miles in 3 hours.
Andre traveled 228 miles in 6 hours. Both Jada and Andre traveled at a constant speed.
To find:
How far did Jada travel in 1 hour?
Solution:
We have,
Distance traveled by Jada in 3 hours = 135 miles
Then,
Distance traveled by Jada in 1 hour = [tex]\dfrac{135}{3}[/tex] miles
= 45 miles
Therefore, Jada travel 45 miles in 1 hour.

the cost for a bakery to make a dozen muffins is 2.52. the sale price of an individual muffin is 2.99. for one day, the bakery will donate 1/2 of the profits from muffin sales to charity. what is the bakeries donation, in dollars, if 88 muffins are sold that day
Answer:
I'm pretty sure it would be $131.56
Step-by-step explanation:
I think it will be $131.56 because if you take an multiply the 2.99 times 88 the number of muffins that were sold that day, then you would get $263.12. If you donated 1/2 of the profits made, then you would take 263.12 and divide it by 2 because half of it would be divided by 2. So therefore you would get $131.56! Hope this helps!

Miguel and Beth like to play video games together. Miguel has m video games, and Beth has b video games. Miguel has
4 more video games than Beth, and together they have a total of 24 video games. Which system of equations can be
used to find how many video games belong to each friend?
Answer:
Miguel has video games = 14
Beth has video games = 10
Step-by-step explanation:
Miguel has video games = m
Beth has video games = b
We make the equations:
m=b+4 (Miguel has 4 more video games than Beth)
m+b=24 (together they have a total of 24 video games)
So, the system of equations is:
[tex]m=b+4\\m+b=24[/tex]
Now, solving these system of equations to find values of m and b
Let:
[tex]m=b+4--eq(1)\\m+b=24--eq(2)[/tex]
Put value of m from equation 1 into equation 2
[tex]m+b=24\\b+4+b=24\\2b=24-4\\2b=20\\b=\frac{20}{2}\\b=10[/tex]
We get value of b: b=10
Now, finding value of m by putting value of b in equation 1
[tex]m=b+4\\m=10+4\\m=14[/tex]
So, We get value of m: m= 14
Therefore:
Miguel has video games = m = 14
Beth has video games = b = 10
Answer:
m+b=24
m=b+4
