Answer:
3√35
Step-by-step explanation:
since √(ab) = √a·√b you can write √5·√7 as √35

|10-4x|-2=9
Please help
I'm assuming you're asking for x.
Answer: -1/4 and 21/4
Step 1: Add 2 to both sides of the equation.
∣10−4x∣=9+2
Step 2: You can get two equations from this.
10−4x=11 and -(10-4x)=11−(10−4x)=11
Solve both equations.
1st equation:
−4x=11−10
−4x=1
x=-1/4
2nd equation:
−10+4x=11
4x−10=11
4x=11+10
4x=21
x=21/4
Answer:
[tex]x=-\frac{1}{4} , \frac{21}{4}[/tex]
Step-by-step explanation:
Isolate the absolute value signs by adding 2 to both sides of the equation.
[tex]|10-4x|=11[/tex]Create a positive and negative case to solve for absolute value problems.
[tex]10-4x=11 \\ 10-4x=-11[/tex]Subtract 10 from both sides of both equations.
[tex]-4x=1 \\ -4x=-21[/tex]Divide both sides of each equation by -4 in order to isolate and solve for x.
[tex]x=\frac{1}{-4} \\ x= \frac{-21}{-4}[/tex]Simplify these x-values by canceling out the negative sign (2 negatives = 1 positive).
[tex]x= -\frac{1}{4} \\ x = \frac{21}{4}[/tex]x = -1/4 and 21/4 are the solutions to this equation.

A water-salt mixture calls for 3/4 cup if salt to be placed in 5 1/2 cups of water if i use 1 cup if salt how much water should i use to preserve the proper water to salt ratio
Answer:
7⅓ cups of water
Step-by-step explanation:
Water-salt mixture ratio = ¾ cup of salt to 5½ cups of water (¾ : 5½)
To maintain this water to salt ratio, if you intend to use 1 cup of salt, the number of water you need to add can be calculated as follows:
¾ cup of salt : 5½ cups of water = 1 cup of salt : x cups of water
¾ : 5½ = 1 : x
[tex] \frac{\frac{3}{4}}{5\frac{1}{2}}. = \frac{1}{x} [/tex]
[tex] \frac{\frac{3}{4}}{\frac{11}{2}} = \frac{1}{x} [/tex]
[tex] \frac{3}{4}*{\frac{2}{11} = \frac{1}{x} [/tex]
[tex] \frac{3}{2}*{\frac{1}{11} = \frac{1}{x} [/tex]
[tex] \frac{3*1}{2*11} = \frac{1}{x} [/tex]
[tex] \frac{3}{22} = \frac{1}{x} [/tex]
Cross multiply
[tex] 3x = 22 [/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{22}{3} [/tex]
[tex] x = 7\frac{1}{3} [/tex]
Number of cups of water to add to 1 cup if salt is 7⅓ cups.
Evaluate: 8[1/4]
0
1
2
3
Answer:
0
Step-by-step explanation:
on edge step functions assignment
The value of 8[1/4] is 0, the correct option is A.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
The number= 8[1/4]
Now,
To evaluate 8[1/4], we need to use the definition of the square bracket notation. The square bracket notation means to round down to the nearest integer. For example, [3.7] = 3 and [-2.1] = -3.
So, 8[1/4] means to multiply 8 by the integer that is closest to 1/4 but less than or equal to it. The integer that is closest to 1/4 but less than or equal to it is 0. So, 8[1/4] = 8 * 0 = 0.
Therefore, by algebra the answer will be 0.

Nellie purchased 6.5 pounds of strawberries for $12.87. Calculate the cost of a single pound. (Round to the nearest tenth or cent when necessary)
Answer:
The answer is $1.98.
Step-by-step explanation:
The butterfly method shows how to do this. It is 12.87 over 6.5 equals x over 1. Cross-multiply to get 6.5x = 12.87. Divide both sides by 6.5 to get x = 1.98.
Describe a transformation that could be used to show that alternate interior angles are congruent.
Answer:
Step-by-step explanation:
From the picture attached,
Let 'l' be the original line having one angle ∠BAC.
If the original line 'l' is shifted or translated to line 'm', angle BAC will replace the angle BDE.
Since, measure of angles are preserved in the translation,
m∠BDE = m∠BAC [corresponding angles]
Since, ∠BDE ≅ ∠MDA [Vertical angles]
Therefore, m∠MDA = m∠BAC
Hence, alternate interior angles (∠MDA) and (∠BAC) will be congruent when line 'l' is translated to line 'm'.
The grocery store sells cantaloupes for $4.50 per pound. Write a function c to

The points A, B, C, and D are plotted on a line, consecutively. AB = BC = CD = 6 cm. Find the distance between M and N, which are the midpoints of segments
AB
and
CD
, respectively. Fill in the blanks of the Statement/Reason solution.
Statement Reason
1. AM = BM = AB 2 =_____ cm 1. ____________________
2. CN = _____ = CD 2 = _____ cm 2. Def. of midpoint
3. MN = MB + ______ + CN 3. ____________________
4. MN = ________ cm 4. Algebra
Answer:
Step-by-step explanation:
If M is the midpoint of AB, then AM = MB
Also AM+MB = AB
MB+MB = AB
2MB = AB
2MB = 6
MB = 6/2
MB = 3 cm
Also
If M is the midpoint of CD, then CN = DN and CN+DN = CD
CN+CN= CD
2CN = CD
2CN = 6
CN = 6/2
CN = 3 cm
Note that MN = MB + BC + CN
Substitute the given data
MN = 3cm + 6cm+3cm
MN = 12cm
Therefore the distance between M and N is 12cm
The distance between of the AM = BM = AB/2 is 3 cm, NC = ND = DC is 3 cm, MN = MB + DC + NC, and MN is 6.
What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The points A, B, C, and D are plotted on a line, consecutively. AB = BC = DC = 6 cm. Find the distance between M and N, which are the midpoints of segments AB and DC, respectively.
Then we know
[tex]\rm AM = MB \\\\NC = ND[/tex]
Then we have
[tex]\begin{aligned} \rm AM + MB &= \rm AB\\\\ \rm AM+AM &=6 \\\\ \rm AM &= 3 \end{aligned}[/tex]
Similarly, we have
[tex]\begin{aligned} \rm NC + ND &= \rm DC\\\\ \rm NC+NC &=6 \\\\ \rm NC &= 3 \end{aligned}[/tex]
NC = ND = 3 cm
AM = MB = 3 cm
1. AM = BM = AB/2 = 3 cm.
2. NC = ND = DC = 3 cm.
3. MN = MB + DC + NC.
4. MN = MB + DC + NC = 3 + 6 + 3 = 12 cm.

In the diagram, bisects ABC. Find mABD and mDBC
Answer:
mABD=24
mDBC=24
Step-by-step explanation:
First, set up x+15 and 4x-12 as equivalent equations
Subtract x from both sides to get 3x-12=15
Add 12 to get 3x=27
x=9
Plug 9 into the original equations representing the measurements of angles
You should get 24 for both because bisected means both are congruent

d. How many did not ride on any of the three modes of transportation?
Answer:
A.) bus only = 23
B.) LRT only = 34
C.) Jeep only = 9
D.) 5
Step-by-step explanation:
Let :
B = bus ; J = Jeep ; L = LRT
KINDLY CHECK ATTACHED PICTURE FOR DETAILED EXPLANATION
A set is a group of related item.
34 had ridden on LRT only23 had ridden on bus only9 had ridden on jeep only5 did not ride on anyLet:
[tex]Total =120[/tex]
[tex]B = 68 \to Bus[/tex]
[tex]L = 78 \to LRT[/tex]
[tex]J =33 \to Jeep[/tex]
[tex]n(B\ n\ L) = 40[/tex]
[tex]n(B\ n\ J) = 20[/tex]
[tex]n(L\ n\ J) = 19[/tex]
[tex]All = 15[/tex]
(a) Bus only
This is calculated using:
[tex]B\ only = B - n(B\ n\ L) - n(B\ n\ J) + All[/tex]
So, we have:
[tex]B\ only = 68 - 40 - 20 + 15[/tex]
[tex]B\ only = 23[/tex]
(b) LRT only
This is calculated using:
[tex]L\ only = L - n(B\ n\ L) - n(L\ n\ J) + All[/tex]
So,
[tex]L\ only = 78 - 40 - 19 + 15[/tex]
[tex]L\ only = 34[/tex]
(c) Jeep only
This is calculated using:
[tex]J\ only = J - n(B\ n\ J) - n(L\ n\ J) + All[/tex]
So, we have:
[tex]J\ only = 33 - 20 - 19 + 15[/tex]
[tex]J\ only = 9[/tex]
(d) None
Let x represents those that took none of the means of transport.
So, we have:
[tex]Total = B\ only + J\ only + L\ only + [n(B\ n\ L) -All] +[n(B\ n\ J) -All] +[n(L\ n\ J) -All] + All + x[/tex]
This gives
[tex]120= 34 + 23 + 9 + [40 -15] +[20 -15] +[19 -15] + 15 + x[/tex]
[tex]120= 115 + x[/tex]
Collect like terms
[tex]x = 120 - 115[/tex]
[tex]x = 5[/tex]
