5(x + 1) - 8 = 5x(2-4)
what is the value of x?
a. -5
b. -1/5
c. 5
d. 1/5
Answer:
d) 1/5
Step-by-step explanation:
5(x + 1) - 8 = 5x(2-4)
5x+5-8 = 5x(-2)
5x-3=-10x
15x = 3
x = 1/5
Answer:
d. 1/5Step-by-step explanation:
5(x + 1) - 8 = 5x(2-4)
=> 5x + 5 - 8 = 10x - 20x
=> 5x + 20x - 10x = 8 - 5
=> 15x = 3
[tex] = > x = \frac{3}{15} [/tex]
=> x = 1/5 (option d) (Ans)

Tyron made 60 cakes. He gave 20% of his cakes to Ana . And 1/6 of his cakes to Dora. What fraction of the 60 cakes does he have left?
Answer:
19/30
Step-by-step explanation:
Total cakes made by Tyron = 60
Cakes given to Ana = 20% of 60
[tex]=\dfrac{20}{100}*60\\\\= 2*6\\\\= 12 \ cakes[/tex]
Number of cakes given to Dora= [tex]\dfrac{1}{6}*60=10[/tex]
Remaining cakes = 60 - ( 12 +10)
= 60 - 22
= 38 cakes
Fraction of left cakes = [tex]\dfrac{38}{60}=\dfrac{19}{30}[/tex]

20. Your friend says the absolute value equation |2x + 9 + 7 = 3 has two solutions
because the constant on the right side of the equation is positive. Is your friend
correct? Explain.
This is an absolute value problem. In mathematics, absolute value is simply defined as the distance of a number from zero on the number line, irrespective of the direction on either side of zero.
In the absolute value given which is; |2x + 9| = -4, we can see that there is an absolute value when the right hand side is negative and not when it is only positive.
Thus, the friend is not correct.We are given the equation;
|2x + 9| + 7 = 3
Now when dealing with absolute values, it means that the solution is either positive or negative.
For example;
|x| = 5 means that x = +5 or -5
Thus in this question, let us first of all simplify the equation to get;
|2x + 9| = 3 - 7
|2x + 9| = -4
From |2x + 9| = -4, we can see that there is an absolute value when the right hand side is negative and not when it is only positive.
Thus, the friend is not correct.

If △ABC is translated down nine unit(s) and to the right two unit(s), which
of the following would be the new coordinates of point A?
Answer:
A'(2, -5)
Step-by-step explanation:
we only need to focus on point a (0,4). The translation is moved 9 units down and 2 units to the right, so point (x,y) would become (x+2, y-9). plug 0 and 4 in for x and y respectively, and you get (0+2, 4-9) = (2, -5)
If R is the midpoint of QS, find QS. (2x + 16) and (5x - 17) Brainliest to correct answers. Please no spamming or random answers this is due tmrw thx.
Answer:
QS = 76
Step-by-step explanation:
Given R is the midpoint of QS , then
RS = QR , that is
5x - 17 = 2x + 16 ( subtract 2x from both sides )
3x - 17 = 16 ( add 17 to both sides )
3x = 33 ( divide both sides by 3 )
x = 11
Then
QS = QR + RS
= 2x + 16 + 5x - 17
= 7x - 1
= 7(11) - 1
= 77 - 1
= 76

Mrs. Magee purchased 3 ice cream cones with a $10 bill. Mrs. Magee was given $2.86 in change. What is the price of one ice cream cone?
Answer
5.56
Step-by-step explanation
The price of one ice cream cone is $2.38
The given parameters;
the money given by Mrs Magee for the 3 ice cream cones = $10the change given to Mrs Magee = $2.86The actual amount Mrs Magee purchased the 3 ice cream cones;
Total amount paid = $10 - $2.86 = $7.14
The price of one ice cream cone is calculated as follows;
[tex]Price \ of \ each = \frac{Total \ cost}{total \ number } \\\\Price \ of \ each = \frac{\$7.14}{3} = \$2.38[/tex]
Thus, the price of one ice cream cone is $2.38

The greater of two numbers is 6 more than 4 times the smaller. Their sum is 41. FInd the numbers.
Answer:
7 and 34
Step-by-step explanation:
let x and y be the 2 numbers with x > y
The 2 equations to solve are
x = 4y + 6 → (1)
x + y = 41 → (2)
Substitute x = 4y + 6 into (2)
4y + 6 + y = 41 , that is
5y + 6 = 41 ( subtract 6 from both sides )
5y = 35 ( divide both sides by 5 )
y = 7
Substitute y = 7 into (1)
x = 4(7) + 6 = 28 + 6 = 34
The 2 numbers are 7 and 34
