Answer:
Step-by-step explanation:
first, let the numbers be x and y.
so by question we have,
x+y=54.......(I)
x-y=116......(I I)
now, solve it through elimination method,
x+y=54
x-y=116
here, y and y cancelled out and we get,
or, x+x=54+116
or, 2x=170
or, x=170/2
therefore, x=85
now put value of x in any equation. let's put in eqn (I), we get,
or, x+y=54
or,85+y=54
or, y=54-85
so, y= -31
therefore, the numbers are 85 and - 31.

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?
Step-by-step explanation:
1.5x + 6-3= 4.5x- 2
1.5x+3=4.5x-2
we transposed
4.5x-1.5x= 3+2
3x= 5
we divide both sides by 3
3x/3= 5/3
x= 5/3

Which number is larger, 2x10^-3 or 3x10^-2? Explain.
Answer:
3×10'-2 is larger
Step-by-step explanation:
2×10'-3=0.002
3×10'-2=0.03
Answer:
3x10^-2 is larger
Step-by-step explanation:
2x10^-3 = 0.002
beause 10^-3 = decimal place three place to the left
3x10^-2 = 0.03
beause 10^-2 = decimal place two place to the left
what is the difference between a categorical and continuous variable?
Answer:
In a categorical variable, the value is limited and usually based on a particular finite group. For example, a categorical variable can be countries, year, gender, occupation. A continuous variable, however, can take any values, from integer to decimal.

Compare the two numbers by choosing <, >or =
Answer:
In order to compare the fractions we can first obtain the LCM of the denominators of the two fractions and that is to say
= LCM of 5 and 3 which is 15
= [tex]\frac{2}{5} * 15[/tex]
=6
and also:
= [tex]\frac{1}{3} * 15[/tex]
=5
So in conclusion the numbers 6 and 5 will determine the sign to be used and since 6 is for [tex]\frac{2}{5}[/tex] and 5 is for [tex]\frac{1}{3}[/tex] and numerically 6 is greater than 5 therefore:
[tex]\frac{2}{5} > \frac{1}{3}[/tex]
A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation LaTeX: 1.5s+3.5c=21 represents the relationship between sheets of stickers, LaTeX: s, packs of cardstocks, LaTeX: c, and the dollar amount a kindergarten teacher spent on these supplies.
Answer:
Done
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1).
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.
what is 5x(2x+7)+x(3x-5 do you know
Answer:
43xx
Step-by-step explanation:
5x(2x+7)+x(3x-5)
first, do the equations inside the parentheses
2x+7=9x
3x-5=-2x
so,
5x(9x)+x(-2x)
Next, do 5x times 9x
(5x) x (9x) = 45
so,
45+x(-2x)
Next, do x times (-2x)
(x) x (-2x)=-2xx
so,
45+-2xx
=43xx

Hello NiX010101!
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
Solve : [tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x\\[/tex]
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex]\frac{ 3x-2 }{ 4 } - \frac{ 2x+3 }{ 3 } = \frac{ 2 }{ 3 } -x \\ [/tex]
Multiply both the sides by the LCM of 4, 3 which is 12. After some simplification you'll get it as ..
[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x [/tex]
Now, use the distributive property to open the brackets.
[tex]3\left(3x-2\right)-4\left(2x+3\right)=8-12x \\ 9x - 6 - 8x - 12 = 8 - 12x[/tex]
Now, bring the like terms together & simplify it.
[tex]9x - 6 - 8x - 12 = 8 - 12x \\ 9x - 8x - 6 - 12 = 8 - 12x \\ x - 18 = 8 - 12x \\ x + 12x = 8 + 18 \\ 13x = 26 \\ x = \frac{26}{13} \\ \large \boxed{\boxed{ \bf x = 2}}[/tex]
We got the value of x as 2.

Find two consecutive even integers such
that 5 times the smaller integer is 44 more
than 2 times the larger integer.
Step-by-step explanation:
5n = 44 + 2(n+2)
5n = 44 +2n+4
5n-2n = 48
3n = 48
n = 16
the integers are : 16 and 18
Use any method to solve the equation. If necessary, round to the nearest hundredth.
8x^2 + 18x - 24 = 0
Answer:
the values are x= 0.94 and x= -3.19

The sum of two numbers is 5 and their product is â’84. Find these numbers
The answer is 12 , -7
I just need the steps
Answer: -7, 12
Step-by-step explanation:
a+b = 5
a*b = -84
a = 5-b
(5-b)*b = -84
-b^2 + 5b + 84 = 0
(-b - 7)(b + 12) = 0
The roots are -7 and 12.

4) Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each
session. If Allison has already practiced 3 hours this week, how many more sessions remain for her to meet
or exceed her weekly practice goal?
Answer:
12
Step-by-step explanation:
So, she practices 12 hrs per week, and already has practiced 3 hrs this week.
This means she has 9 hrs left to practice.
3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)
which is basically 9 / ( 3/4)
[tex]\frac{9}{3/4}=\frac{9}{1} / \frac{3}{4} = \frac{9}{1} * \frac{4}{3} = \frac{36}{3} = 12[/tex]
She needs 12 more sessions.

Evaluate for z
11 + 3/5z = 38
Answer:
45
Step-by-step explanation:
Combine 3/5 and z
Move all terms not containing z to the right side of the equation.
3z/5=27
Multiply both sides of the equation by 5/3
Simplify both sides of the equation.
z=45
16. For any two integers a and b, (a + b)2 = a² + b2
true or false
Answer:
false is the answer ........
Solution:
(a+b)^2 = (a+b)(a+b)= a^2 + ab + ab + b^2= a^2 + 2ab + b^2So the statement is false and the correct statement is:
For any two integers a and b, (a+b)^2 = a^2+2ab+b^2.
