Answer:
The value of x is 5
Step-by-step explanation:
Let us simplify each side at first
∵ 2(x - 3) = 4(x - 4)
∴ 2(x) - 2(3) = 4(x) - 4(4)
∴ 2x - 6 = 4x - 16
→ Subtract 4x from both sides
∴ 2x - 4x - 6 = 4x - 4x - 16
∴ -2x - 6 = -16
→ Add 6 to both sides
∴ -2x - 6 + 6 = -16 + 6
∴ -2x = -10
→ Divide both sides by -2
∴ [tex]\frac{-2x}{-2}=\frac{-10}{-2}[/tex]
∴ x = 5
∴ The value of x is 5

i took the test
Answer:
c
Step-by-step explanation:
Christina's grade for her history class will be the average of
her midterm exam, final exam, and final paper. She received a
91 on her midterm and an 86 on her paper. What grade must
she get on her final exam to receive a grade of 90 for the
class? Explain using R.A.C.E.
The average is calculated by the sum of the total test scores divided by the total number of tests. This can represented in the equation:
91 + 86 + x /3 = 90
177 + x /3 = 90 ⇒ Multiply both sides by 3 to get rid of the /3
177 + x /3 x 3 = 90 (3)
177 + x =
177 - 177 + x = 270 - 177 ⇒ Subtract 177 from both sides to isolate x
x =93
Therefore, they must get 93% to end with a 90% final mark

The total number of students enrolled at Phillips Middle School is 1,800 students. If the ratio of boys to girls is 4 to 5 for the school, how many students are boys and how many are girls? Show your work.
Answer:
There are 800 girls and 1000 boys.
Step-by-step explanation:
The total no of students enrolled = 1800
Ratio of boys to the girls is 4:5.
Let there are 4x boys and 5x girls.
ATQ,
4x+5x=1800
9x=1800
x = 200
No of boys = 4x = 4(200) = 800
No of girls = 5x = 5(200) = 1000
So, there are 800 girls and 1000 boys.

The price of onion increased by 12 %. By how much % you should reduce your consumption at home so that your expenditure on onion does not increase?
Answer:
Let the price before increase be 100
Increased price =25percent of 100
25/100*100+100=125
When the price is increased to 125 she has to reduce 25
When the price is increased to 1 she has to reduce 25/125
Rate by which consumption decreases=25/125*100
=20 percent
Therefore she has to reduce 20percent consumption of onion so that there will be no change in her expenditure
Given that mZ1 = 34•, determine mZ2.
Answer:
m/2= 134 degrees
Step-by-step explanation:
90 - 34 = 56
180 - 56 = 134
So angle 2 would be 134 degrees.

check those that are not monomine..
9514 1404 393
Answer:
2/x5/yStep-by-step explanation:
A monomial is one term, which may be a constant. In the context of a polynomial, the literals in a term have non-negative integer exponents.
A fraction with a variable in the denominator is a rational expression, not considered to be a "term."
2/x and 5/y are not terms, so not monomials.
_____
Further explanation
In a larger context, a term is any mathematical expression that is to be considered as a unit. It may include radicals, rational expressions, even sums or differences. So, the expressions 2/x and 5/y may be considered to be terms in a different context than here. For example, we could say that ...
2x⁻¹ +5y⁻¹
is a 2-term expression, though it could not be part of any polynomial.
What is the slope of the line that passes the points (-8, 7) and (16, 22)
Answer:
slope = [tex]\frac{5}{8}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, 7) and (x₂, y₂ ) = (16, 22)
m = [tex]\frac{22-7}{16+8}[/tex] = [tex]\frac{15}{24}[/tex] = [tex]\frac{5}{8}[/tex]

the perimeter of a rectangular window is 280cm. if the length of the window is 83cm, what is the width
Answer:
the width would be 57cm
Step-by-step explanation:
to find the perimeter you have to add up all of the sides so for this one you would multiply 83 by 2 which would give you 166cm and then subtract it by 280cm which would give you 114cm and then you divide 114 by 2 which would give you 57

Find the equation of line passing through the points A(-1,3) and B(0,2). Hence show that the points A,B and C (1,-1) are collinear.
A line passes through A( - 1 , 3) & B(0 , 2).
Prove:A , B , C(1 , 1) are collinear.
Proof:We know that,
Slope of a line passing through the co - ordinates (x₁, y₁) and (x₂ , y₂) is :
m = (y₂ - y₁)/(x₂ - x₁)
Let,
x₁ = - 1 x₂ = 0 y₁ = 3 y₂ = 2Hence,
→ m = (2 - 3)/( 0 - ( - 1))
→ m = - 1/1
→ m = - 1
Now,
Equation of a line ⟹ y - y₁ = m (x - x₁)
Putting the values we get,
→ y - 3 = - 1(x - ( - 1))
→ y - 3 = - x - 1
→ y + x = - 1 + 3
→ x + y = 2
Hence, the equation of the line is x + y = 2.
Now,
we have to prove that,
A , B , C are collinear.
If three points are collinear then the area of the triangle formed by them will be zero. Three points are collinear if the slope of line passing through the line segment are equal.i.e.,
Slope of AB should be equal to Slope of BC.
We have;
Slope of AB = - 1.
→ - 1 = ( 1 - 2)/(1 - 0)
→ - 1 = - 1/1
→ - 1 = - 1
Hence, A , B , C are collinear points.
I hope it will help you.
Regards.
Bob runs 4 laps around a track in 10 minutes. A) How many minutes per lap is that? B) How many laps per minute is that? C) If Bob runs 17 laps at the same rate, how long does it take him?
Answer:
Step-by-step explanation:
Firstly, let us solve for Bobs speed
speed= distance/time
given
distance= 4 laps
time= 10 min
speed= 4/10
speed=0.4laps/min
this is the rate at which Bob is running
A) How many minutes per lap is that?
this is given as
=time/distance
=10/4
=2.5 min per lap
B) How many laps per minute is that?
this is given as
=distance/time
=4/10
=0.4lad per min
C) If Bob runs 17 laps at the same rate, how long does it take him?
given that the speed is 0.4 laps per min
and a distance of 17 laps, we want to find time
speed=distance/time
0.4=17/time
time=17/0.4
time=42.5min
