1. un numar se mareste cu 4 iar rezultatul se mareste de 4 ori. noul rezultat micsorat cu 4 se imparte la 4 si se obtine 4.aflati numarul
Răspuns:
1
Explicație pas cu pas:
Fie numărul = x
x + 4 = e - - (1)
e * 4 = f - - - (2)
Ecuația 2 - 4 împărțită la 4 = 4
(f - 4) / 4 = 4
Crucea se înmulțește
f - 4 = 16
f = 16 + 4
f = 20
Rezultatul 1 împărțit la 4 este egal cu 4
Prin urmare,
e = f / 4
f = 20
e = 20/4
e = 5
De la (1)
x + 4 = e
x + 4 = 5
x = 5 - 4
x = 1

[tex]\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]The sum of three times a number (2) and -23 is 28.
Answer:
x = 17
Step-by-step explanation:
3x + -23 = 28
3x - 23 = 28
3x = 28 + 23
3x = 51
x = 51/3
x = 17

laura spent 2/5 of her money now she has $18 left how much money did she have origanily
Answer:
Money Laura had originally = $30
Step-by-step explanation:
Let the money Laura had = x
Money spent = 2/5 of x = [tex]\frac{2}{5}x[/tex]
Remaining money = $ 18
[tex]x - \frac{2}{5}x = 18\\\\\frac{x*5}{1*5}-\frac{2}{5}x = 18\\\\\frac{5x}{5} - \frac{2x}{5} = 18\\\\\frac{3x}{5}=18\\\\ 3x = 18*5\\\\3x = 90\\\\x = \frac{90}{3}\\\\x = 30[/tex]
Money Laura had originally = $30
The following system of equations is given below:
\large -5x+y=-18
\large -10x-5y=20
Which of the following steps is not suitable to solve this system by elimination?
a. Multiply the first equation by 2 and then subtract the equations from each other.
b. Multiply the first equation by -5 and then add the equations together.
Selected:c. Multiply the first equation by 5 and then add the equations together.This answer is incorrect.
d. Multiply the first equation by -2 and then add the equations together.
Answer:
both b and c are correct options

e(x) = -x + -6
Find e(-2)
Answer:
I'm pretty sure it's -4
Step-by-step explanation:
If you substitute in -2, you get e(-2)= -(-2)+ -6
which is equal to 2-6
2-6=-4
Answer:
e(-2)=-4
Step-by-step explanation:
e(-2)=-(-2)+-6
=2-6

If on a scale drawing 75 feet are represented by 45 inches, then a scale of 1/5 represents how many feet
Answer:
1/3 feet
Step-by-step explanation:
We are given that
On a scale drawing
45 inches represented =75 feet
We have to find a scale of 1/5 inch how many feet represents.
To find the value in feet represented by a scale of 1/5 inch we will use unitary method.
Using unitary method
45 inches represents =75 feet
1 inch represents = feet
1/5 inch represents = feet
1/5 inch represents= feet
Hence, a scale of 1/5 inch represents 1/3 feet

Multiple Choice: Choose the correct answer for questions 1 and 2.
1. The height of Trisha, a 17-year-old female student, is in the lower quartile for height for girls aged 16 to 18. This statement means:
A. Trisha's height is average for her age.
B. Trisha is shorter than 25% of girls aged 16 to 18.
C. Trisha is shorter than 75% of girls aged 16 to 18.
D. Trisha is taller than 75% of girls aged 16 to 18.
What is the answer
Answer:
The correct answer is:
C. Trisha is shorter than 75% of girls aged 16 to 18.
Step-by-step explanation:
When a dataset is divided into four equal parts, the first part is called the lower quartile. The data is usually sorted in ascending order before finding quartiles.
The lower quartile contains 25% of the whole data. The values in lower quartile are are less than 75% of the values.
If Trisha's height is in lower quartile that means her height is less than the girls in middle and higher quartile.
Hence,
The correct answer is:
C. Trisha is shorter than 75% of girls aged 16 to 18.

are there instances that rational algebraic equation can be transformed into quadratic equation
Answer:
yeah
Step-by-step explanation:
hmm
Answer:
yes you can
Step-by-step explanation:
for example you have a second order algebraic equation, which have the general form ax^2 + bx + c = 0, for any constants a, b, and c, you can use the quadratic equation to find the values of x. However, sometimes it is easier to simply factor the expression into (fx+g)(hx+i) = 0, for any constants f, g, h, and i, and then solve the two resulting equations fx+g = 0 and hx+i=0 for the values of x.
i hope this helps

a
(5pts) Find: m∠AOF
PLEASE HELP
Answer:
m∠AOF=110°
Step-by-step explanation:
∠AOB is 180°, ∠FOB is 70°. To find m∠AOF, subtract 70 from 180. 180-70=110

Answer:
m∠AOF=110°
Step-by-step explanation:
∠AOB is 180°, ∠FOB is 70°.
If you want to find m∠AOF, subtract 70 from 180. 180-70

The sum of two numbers is 59. The smaller number is 5 less than the larger number. What are the numbers?
Help please
Answer:
The answer is 32 & 27 because they add up to 59 and 27 is 5 less than 32.
Step-by-step explanation:
Answer:
32, 27
Step-by-step explanation:
Call one number (the larger one) "x"
The other number (smaller one) is " x - 5"
As per the given information;
x + x - 5 = 59
Inverse operations;
x + x - 5 = 59
+5 +5
2x = 64
/2 /2
x = 32
Larger number= 32
Smaller numbers = x - 5 = 32 - 5 = 27
