Answer:
t=10
Step-by-step explanation:
4=t/2.5
4=t/25/10
divide 25and10 by 5=5/2
4=t/5/2
4=t×2/5
multiply both sides of the equation by 5
5×4=t×2/5×5
20=t×10/5
20=t×2
— —
2. 2
10=t

Would this be X method factoring and how would I do it if X isn’t alone to begin with
Answer:
Option C
Step-by-step explanation:
Given polynomial is,
x² - 3x - 18 = x² - 6x + 3x - 18
= x(x - 6) + 3(x - 6)
= (x + 3)(x - 6)
We can rewrite the polynomial in factored form as,
x² - 3x - 18 = (x - 6)(x + 3)
Therefore, (x - 6) will be one of the factors of the given polynomial.
Option (C) is the answer.

What is the value of x?
Answer:
x = 14
Step-by-step explanation:
Hey there! When it comes to the problem here, both of the degrees should be equal to each other. Setting it up, 4x+1=57 would be how it would be written out, and then you would subtract the 1 to get the 4x by itself. From there, you'd divide 56 by 4, getting you 14. I hope this helped! <3

Tj Max is offering a 15% discount on all items .The new price of a pair of jeans is 44.20 .What was the original price
Answer:
$52
Step-by-step explanation:
To find an original price you must find how much of a percent was left before the discount.
100% - 15% = 85%
You then take this percentage a DIVIDE it by the new price.
$44.20/85% = $52 is the original price of the jeans.
The perimeter of a rectangular parking lot is 360 m. If the width of the parking lot is 85 m,what is it’s lenght?
Answer:
95m
Step-by-step explanation:
Formula:p=2(l+w)
360m=2(l+85m)
360m=2l+170m
360m-170m=2l
190m/2=2l/2
L=95m

CHALLENGE Sara had some marbles. She got 20 more marbles for her
birthday, and she got 30 marbles at the store. Now Sara has 100 marbles.
How many marbles did she have to start?
Answer:
she started with 50 marbles
Step-by-step explanation:
The total is 100 than you just subtract 20 and 30 becasue that is what is added later on. After you subtract 20 and 30 from 100 you will get 50. Therefore Sara had started out with 50 marbles.
Hope that helps :)
Answer: 50 marbles
Step-by-step explanation: Working backwards we ended with 100 marbles so subtracting the 30 marble we're told she bought at the store and subtracting an additional 20 marbles she received for her birthday leaves her with 50 marbles or mathematically 100-30-20=x where x=50
What is the input value that produces the same output
value in both charts?
O-2
O-1
O 1
O 2
Step-by-step explanation:
When f(x) = g(x),
-0.5x + 2 = 2x - 3.
=> 2.5x = 5, x = 2.
The input value that gives the same output in both charts is 2.
If (a^x a ^y) - a^z = a^m then express m in terms of x, y and z.
Answer:
m = x+y-z
Step-by-step explanation:
Given the expression.
(a^x a ^y) ÷ a^z = a^m
We are to express m in terms of x, y and z.
Using the multiplicative law of indices, the expression becomes:
a^{x+y} ÷ a^z = a^m
Applying the division rule in indices
a^{x+y} ÷ a^z = a^{x+y-z}
The equation becomes
a^{x+y-z} = a^m
Cancel out the base and equate the powers as shown:
x+y-z = m
Hence the expression of m in terms of x, y and z is m = x+y-z

The midpoints of an irregular quadrilateral ABCD are connected to form another quadrilateral inside ABCD. Complete the explanation of why the quadrilateral is a parallelogram.
Answer:
Suppose: M, N, P, Q are the midpoints of AB, BC, CD, AD respectively
=> MNPQ is the quadrilateral inside ABCD
connect B to D, ΔABD has : M is the midpoint of AB
Q is the midpoint of AD
=> MQ is the midpoint polygon of ΔABD
=> MQ // BD and MQ = 1/2.BD (1)
ΔBCD has: N is the midpoint of BC
P is the midpoint of DC
=> NP is the midpoint polygon of ΔBCD
=> NP // BD and NP = 1/2.BD (2)
from (1) and (2) => MQ // NP ( //BD)
MQ = NP (=1/2.BD)
=> MNPQ is a parallelogram.
=> the quadrilateral inside ABCD is a parallelogram.

Which expression is equivalent to the one below?
o -1/2(10+ 1/4)
o -5 - 1/4
o -5 + 1/8
o -5 +1/4
Please help me :)
Answer:
The answer is -5 + 1/8
Step-by-step explanation:
If you use the distributive property, which is mandatory with parenthesis you first multiply -1/2 by 10 which is -5. The next step is to multiply -1/2 by 1/4 which is -0.125 or -1/8, which the closest answer to it is -5 + 1/8. Hope this helps :)
Algebraic expression of twice a number, minus 13
Answer:
2x-13
Step-by-step explanation:
The perimeter of a rectangle is 48 cm. If the length is 3 cm more than a number and the width is 6 cm more than twice the same number. What is the number?
Answer:
x = 5cm.
Step-by-step explanation:
Let the number be x
Given the following data;
Length of rectangle = x + 3
Width of rectangle = 2x + 6
Perimeter of rectangle = 48 cm
The formula for the calculating the perimeter of a rectangle is;
Perimeter = 2(L+W)
Substituting into the equation, we have;
48 = 2(x + 3 + 2x + 6)
48 = 2(3x + 9)
48 = 6x + 18
48 - 18 = 6x
30 = 6x
x = 30/6
x = 5
