Answer:
x = 30
Step-by-step explanation:
The perimeter is the sum of all of the sides of a shape. Therefore, because the sum is equivalent to 104 inches and we are given the lengths of all three sides, we can add the three sides together and set them equal to 104 in order to solve for x.
(x + 3) + (x + 4) + (x + 7) = 104 Drop the parentheses.
x + 3 + x + 4 + x + 7 = 104 Combine like terms (variables first!).
3x + 3 + 4 + 7 = 104 Now, combine constant terms.
3x + 14 = 104 Subtract 14 from both sides.
3x = 90 Divide by 3 on both sides of the equation.
x = 30

What is the solution to the equation 3x – 8 = -2?
O A. -3 1/3
O B. 3 1/3
C. 2
D. -2
Answer:
option (c) 2
Step-by-step explanation:
We have the linear equation :-
→ 3x - 8 = -2
add 8 both sides
→ 3x - 8 + 8 = -2 + 8
→ 3x = 6
→ x = 6 ÷ 3
→ x = 2

Solve the system of linear equations in two variables by elimination or substitution.
2x + 4y = 4
2x - y=1
Answer:
x = 0.8 y = 0.6
Step-by-step explanation:
Solve one of the equations for a single variable, I chose the 2nd equation and solved for the variable y and I got y = 2x -1.
Next plug in the value for y into the 1st equation, I got :
2x + 4 ( 2x - 1) = 4
Next solve for x by first distributing the 4 to the (2x-1), this becomes (8x -4) then add like terms and move the -4 to the other side of the equation by addition. I got 10x =8 then I divided 8/10 to solve for x and I got 0.8.
Now plug the value 0.8 in for x in the 2nd equation : 2*(0.8) - y = 1
Then solve for y by subtracting 2*(0.8) or 1.6 from 1 and I got -0.6, lastly divide by -1 to solve for y.

[tex] \boxed{ \bold{ \huge {\boxed{ \sf{ \frac{25}{2} }}}}}[/tex]
Step-by-step explanation:
[tex] \sf{5 \div \frac{2}{5} }[/tex]
When any number of fraction is divided by a fraction , we multiply the dividend by reciprocal of the divisor.
We can obtain the reciprocal of any fraction by interchanging the position of numerator and denominator.
⇒[tex] \sf{5 \times \frac{5}{2} }[/tex]
To multiply one fraction by another, multiply the numerators for the numerator and multiply the denominators for its denominator.
⇒[tex] \sf{ \frac{5 \times 5}{2} }[/tex]
Multiply the numbers : 5 and 5
⇒[tex] \sf{ \frac{25}{2} }[/tex]

Find the equation of the line below.
Answer:
y = 2x
Step-by-step explanation:
The equation of a line is y = mx + b
We can plug in values for x and y,:
x = 1, y = 2
2 = m + b <- equation 1
x = 4 y = 8
8 = 4m + b <- equation 2
We can multiply equation 1 by 4, getting 8 = 4m + 4b.
We can them subtract equation 1 by equation 2, getting 3b = 0.
Therefore, b = 0.
We can use the equation 2 = m + b and find m:
Since b = 0, m = 2.
The equation is then y = 2x.
the Rope is 30m long. how many 3/4 meter pieces can be cut from the rope
Answer:
40
Step-by-step explanation:
Given:
Length = 30 mPieces = 3/4 mNumber of pieces:
30 ÷ 3/4 = 30 × 4/3 = 40 piecesThe are of a rectangle is 50m^2 , the length is 100m . Calculate the width
w = 0.5 m
Step-by-step explanation:A = l × w
50m² = 100m × w
w = 50m²/100m
w = 0.5 m
Answer:
The answer is 0.5 m i.e Width = 0.5 m
Step-by-step explanation:
Given,
Area (A) = [tex]50m^{2}[/tex]
length (l) =100 m
width ( b ) = ?
Now,
A = l * b
or, 50 = 100 * b
or, [tex]\frac{50}{100}[/tex]= b
or, b = 0.5 m

what is the standard deviation for 54, 36, 30, 28, 27
Answer:
11.18
Step-by-step explanation:
Step 1: average : (54+36+30+28+27) / 5 = 35
Step 2: variance:
sum of the squares of (each number - average value) divided by (n-1)
[ (54-35)^2 + (36-35)^2 + (30-35)^2 + (28-35)^2 + (27-35)^2 ] / (5-1) = 125
Step 3: standard deviation = √(variance) = √125 = 5√5 (about 11.18)
the presence of a segment bisected will result in what type of segments?
A: noncoplanar segments
B. parallel segments
C. congruent segments
D. perpendicular segments
first person to get it right will get brainliest
Answer:
Option C → Congruent segments
Step-by-step explanation:
The meaning of segment bisector is a segment which divides another segment into two equal parts.It is not necessary that the segement which is bisecting the another segment are perpendicular with one another.
So, when a segment is bisected the two segments are equal.
Equal means the two segments are congruent.
Most appropriate statement
Answer:
Congruent.
Step-by-step explanation:
Bisecting will give 2 segments of equal length.
A store sells three varieties of cheese cheddar, Gouda, and Swiss. Each variety of cheese is available in two different styles shredded or sliced. How many possible outcomes for the variety and style of cheese are there?
Answer:
6 possible outcomes
Step-by-step explanation:
To solve this problem, we have to make use of the Fundamental Counting Principle formula.
The formula counting principle states that when we are given two or more distinct events, in order to get the total number of possible outcomes, we multiply such events together.
In the above question, we are given two events.
Event 1
3 varieties of cheese: Cheddar, Gouda, and Swiss.
Event 2
2 styles of cheese: Shredded and Sliced
The possible outcomes for the variety and style of cheese = Event 1 × Event 2
= 3 × 2
6 possible outcomes.
These 6 Possible outcomes are listed below:
1) Cheddar cheese , Shredded
2) Cheddar cheese , Sliced
3) Gouda cheese , Shredded
4) Gouda cheese , Sliced
5) Swiss cheese , Shredded
6) Swiss cheese , Sliced
