Todd hired a handyman to replace some tiles in his bathroom. He paid him $24 per hour of work and $15 as a tip.
If the handyman worked for t hours, the amount he got paid is given by the expression:
A. t+24+15
B.24t+15t
C.24t+15
D.24(t+15)
If he worked for 3 hours, he would receive:
A.42$
B.87$
C.93$
D.117$
Answer:
1. C 24t+15
2. B. 87
Step-by-step explanation:
Since he gets $24 an hour, you have to multiply the number of hours by how much he gets paid, that would be the 24t part. Since he has a $15 added tip, you add that to the rest of the equation. He isn't getting $15 an hour, he just gets a flat tip, so you wouldn't multiply it by t. To get the second part, you have to plug in 3 for t since that is how many hours he worked. The equation would look like this: 24(3)+15. You get $87 for this.

Answer: The answers are in the steps please look carefully.
Step-by-step explanation:
In this given situation, the length of RS plus the length of ST will equal to the length of RT because RS and ST lies on RT. We are given that RS is equal to 2x + 10 and ST is equal to x- 4 , this means that 2x + 10 plus x-4 will equal to 21 because the whole length of RT is 21.
A. Equation: (2x + 10 ) +(x -4) = 21
Now solve the equation for x.
2x + 10 + x -4 = 21 First combine like terms on the left side.
3x + 6 = 21 Subtract 6 from both sides
-6 -6
3x = 15 Divide both sides by 3
x = 5
The value of x is 5.
The length of RS is 2x +10 so since we know the value of x input it into the expression and solve for the real length.
2(5) + 10
10 + 10 = 20
ST is also x -4 so input the value for x and solve for the real length.
5 - 4 = 1
x = 5 , RS = 20 , ST = 1
B. The same applies to B.
RS plus ST has to Equal to RT.
We know the length of RS is 3x -16 and the length of ST is 4x -8 so it has to equal 60.
Equation: ( 3x -16) + (4x - 8) = 60 Solve for x
3x - 16 + 4x -8 = 60
7x - 24 = 60
+24 +24
7x = 84
x= 12
Input 12 in for x and solve for the real lengths
RS = 3(12) - 16
RS = 36 - 16
RS = 20
ST= 4(12) - 8
ST= 48 - 8
ST= 40
x = 12, RS = 20, ST = 40

i need help with this geometry
Answer:
i think its 100
Step-by-step explanation:
180-80=100 and since the to one is vertical to where the question mark is , it's also 100
Answer:
100°
Step-by-step explanation:
Alternate angles on a cross section of a parallel line are equal. Because 80° is above it, it needs to be the opposite angle. angles on a straight line are 180° so 80+100=180°

Which is an accurate conclusion regarding the system of equations below?
x + y = 4
y = -x + 4
A) There is no solution, since both equations have the same slope.
B) There are infinitely many solutions, since the same line represents both equations.
C) The only solution is the ordered pair (4, 0).
D) The only solution is the ordered pair (0, 4).
Answer: B) Infinitely many solutions; both equations are equivalent
==============================================================
Work Shown:
x+y = 4 ... start with the first equation
x + (-x+4) = 4 ... replace y with (-x+4)
x-x+4 = 4
0x+4 = 4
0+4 = 4
4 = 4 ... this is a true statement regardless of what x you pick
So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.
Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.

Answer:
7
Step-by-step explanation:
Let the missing value of y in the table be a.
Since, the slope of the line through the ordered pairs (1, 3), (2, a) is 4.
[tex] slope = \frac{a - 3}{2 - 1} \\ \\ 4 = \frac{a - 3}{1} \\ \\ 4 = a - 3 \\ \\ 4 + 3 = a \\ \\ a = 7[/tex]
Thus, the missing value of y in the table is 7

Gina walked 0.8 miles before she started jogging at an average pace of 6 miles per hour. The equation d = 0.8 + 6t can be used to relate the total distance, d, in miles to the time, t, that Gina spent jogging. What are the independent and dependent variables?
Answer:
independent: tdependent: dStep-by-step explanation:
The way the equation is written, d is the dependent variable; t is the independent variable (on which d depends).
Answer:
the independent variable is t (time) and the dependent variable is d (distance)
Step-by-step explanation:
Time is called independent variable because time determines the distance and it stands alone, while distance is dependent variable because the length of distance is determined with the time, meaning when time (t) changes, the distance changes too.
for ex. if t=1, d= 0.8+6 (1) = 6.8

2n - 4 < 3n - 6
Answer: n > 2
Step-by-step explanation:
Step 1: Subtract 3n from both sides
2n-4 -3n < 3n-6 -3n
-n - 4 < -6
Step 2: Add 4 to both sides
-n-4 +4 < -6 +4
-n < -2
Step 3: Divide both sides by -1
-n / -1 < -2 / -1
n > 2
a) work out the radius of the mercury, giving your answer as an ordinary number
b) work out the difference between the masses of jupiter and saturn
Answer:
a. 2,440 km
b. [tex] 1.33*10^{27} kg [/tex]
Step-by-step explanation:
a. Diameter of Mercury = [tex] 4.88*10^3 [/tex]
Radius of Mercury = ½ of its diameter = [tex] \frac{4.88*10^3}{2} [/tex]
Radius of Mercury = [tex] 2.44*10^3 [/tex]
To convert the radius to ordinary number, multiply 2.44 by 1,000.
Radius of Mercury as an ordinary number = [tex] 2.44*1,000 = 2,440 km [/tex]
b. Mass of Jupiter = [tex] 1.898*10^{27} kg [/tex]
Mass of Saturn = [tex] 5.68*10^{26} kg [/tex]
Difference between mass of Jupiter and mass of Saturn = [tex] 1.898*10^{27} - 5.68*10^{26} [/tex] (subtract 5.68 from 1.898 = 5.68. we would retain the largest exponent, which is raised to the lower of 27.)
[tex] = 1.33*10^{27} [/tex]
