Evaluate f(−3).
Solve
f(t) = 2.
Answer:
plug in -3 and 2 into the equations you should get two different numbers
Step-by-step explanation:
3(-3)+2(-3)=24
3(2)+2(2)=24
5(3t) - 7(2)
How do you solve this
Answer:
5(3t)-7(2)=0
15t-14=0
15t=14
t=14/15
Answer:
15t - 14
Step-by-step explanation:
[tex]5(3t) - 7(2)[/tex]
[tex]5 \times (3t) - 7 \times 2[/tex]
[tex]5 \times 3t - 14[/tex]
[tex] = 15t - 14[/tex]

The area of a square is 100 square inches. What is the perimeter of this square?
a. 40 inches
b. 20 inches
c. 10 inches
Answer:
40inches
Step-by-step explanation:
If the area is 100 square inches, therefore on side of the area is just the square root of the area that is 10. Bcuz 10 x 10 =100 Square inch right? So one side is 10. A square has 4 sides, so multiply 10 by 4, u get 40inches
Answer:
40 inches
Step-by-step explanation:
Try finding length first.
Area of square = 100 square inches
or, l square= 100 square inches[ using formula]
or, l=10 inches
Hence, length( l ) = 10 inches
Perimeter of square= 4l
= 4×10 inches
= 40 inches
A truck can be rented from Company A for $70 a day plus $0.70 per mile. Company B charges $20 a day plus $0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same. At nothing miles, the rental costs are the same from either company.
Answer:
500 milesStep-by-step explanation:
Let the number of miles is x.
Then for each company we have total charge of:
A = 0.7x + 70B = 0.8x + 20Since A = B, solve for x:
0.7x + 70 = 0.8x + 200.8x - 0.7x = 70 - 200.1x = 50x = 50/0.1x = 500 milesLet no of miles be y

[tex]6\left(x+4\right)=5\left(x-5\right)+x[/tex]
Apply distributive law:-
[tex]=6x+6\cdot \:4[/tex]
➠ Now, Multiply:- 6 × 4= 24
[tex]6x+24[/tex]
[tex]5\left(x-5\right)+x[/tex]
[tex]=5x-25[/tex]
[tex]=5x-25+x[/tex]
➠ Group like terms:-
[tex]=6x-25[/tex]
Now, we have...
[tex]6x+24=6x-25[/tex]
➠ Subtract 24 from both sides:-
[tex]6x+24-24=6x-25-24[/tex]
[tex]6x=6x-49[/tex]
➠ Now, Subtract 6x from both sides:-
[tex]6x-6x=6x-49-6x[/tex]
[tex]0=-49[/tex]
Here, the sides are not equal so there is no Solution

An athlete runs two miles in 13.5 minutes. How many minutes is this per mile?
Answer:
6.75 minutes / mile.
Step-by-step explanation:
Time: 13.5 minutes
distance: 2 miles
rate: ?
You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.
13.5 minutes
2 miles
13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile

Find 6 3/4 − 4 11/12. Write your answer in the simplest form.
A. 1 2/3
B. 1 5/6
C. 2 5/6
D. 3
ANSWER
First of all I turn the fractions back to their improper form that is to say;
6 3/4 - 4 11/12
= 27/4 - 59/12
after that I get the LCM of 12 and 4 which is 12
= (²⁷/⁴ × 12) - (⁵⁹/¹²× 12) /12
= (81 - 59) /12
= 22\12
since the answer is requested for in the simplest form the the difference in form of a mixed fration is 1 10/12 which is reduced to 1 5/6 therefore the answer is 'B'

The price to mail a letter at the post office is $.49 for the first ounce and $0.21 for each additional ounce. Ann paid $1.96 to mail his letter. How much did the letter weigh?
Answer:
the answer is 8 oz
Step-by-step explanation:
well it says for the first ounce is $0.49 so $0.49 is your first number, then you're trying to figure out how many $.21
2.then to make this easier you subtract $0.49 from $1.96 and that's is $1.47
3.then all you need to do is divide $1.47 By .21 cents anand you should get 7.
4.but don't forget the $0.49 for the first ounce, then 1 ounce add it to the 7 and It will equal 8 oz in total

which reflection carries parallelogram QRST onto itself?
Step-by-step explanation:
that 180° and 360° clockwise and counterclockwise rotations about this point will carry the parallelogram onto itself.
The parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.
What is the parallelogram?
A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel.
This means a parallelogram is a plane figure, a closed shape, and a quadrilateral.
If we rotate it in clockwise then it covers the angle [tex]180[/tex] degree and [tex]360[/tex] degree whether it is in clockwise or in anticlockwise.
Hence, the parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.
