Find the value of x help please.
Answer:
x= 6
Step-by-step explanation:
since the triangle is isosceles we know that opposite sides are equal
[tex]5x+5=35\\\\5x=35-5\\\\5x=30\\\\x=\frac{30}{5}\\\\x=6[/tex]
Answer:
[tex]\boxed {\boxed {\sf x=6}}[/tex]
Step-by-step explanation:
An isosceles triangle has 2 equal base angles and 2 equal legs.
In this triangle, 16 must be the base, because the base angles are adjacent. Therefore, the legs are 35 and 5x+5. They must be equal to each other.
[tex]35=5x+5[/tex]
Solve for the value of x by isolating the variable on one side of the equation.
5 is being added to 5x. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
[tex]35-5=5x+5-5 \\ 35-5=5x\\30=5x[/tex]
x is being multiplied by 5. The inverse of multiplication is division. Divide both sides by 5.
[tex]\frac{30}{5} =\frac{5x}{5} \\\frac{30}{5}=x\\6=x[/tex]
The value of x is 6.
Easy math question, lots of points.
Answer:
LW = 3, KJ = 6, HJ = 5
Step-by-step explanation:
These two triangles are proportionate, as all the angles are the same. Since twp pf the angles from both shapes are equal, the remaining one must also be equal. Since KH = 8 and LG = 4 (both are similar), we can tell that with the similar sides of the small triangle, you multiply by 2 to get the bigger triangle's similar side. If GW = 2.5, HJ = 2.5*2 = 5. LW must be 3 in order to be half of KJ, which is 6.

Find the area of the shape shown below.
Answer:
Total Area = 26.75
Step-by-step explanation:
Remark
The hardest triangle to see is the top one. So we'll start with it.
It has a vertical leg of 3.5 and a horizontal one of 2 + 2 + 5 = 9
Top Triangle Area
Area = 1/2 base * height
Area = 1/2 * 9 * 3.5
Area = 15.75
Triangle on the lower left
Area = 1/2 * 2 * 2
Area = 2
Square on lower middle
Area = 2*2
Area = 4
Triangle on lower right area
Area = 1/2 * 2 * 5
Area = 5
Total Area
Total Area = 5 + 4 + 2 + 15.75
Total Area = 26.75

Suppose that Dr. Vergara makes a free throw with probability 0.8 and, independently, Dr. Agor makes a free throw with probability 0.4. They each attempt one free throw. (a) Given that only one of them made a free throw, what is the probability that Dr. Agor made his free throw
Answer:
The probability that Dr. Agor made his free throw is 40%.
Step-by-step explanation:
Given the fact that Dr. Agor usually converts his free throws with a probability of 0.4, to determine the percentage of probability that he will convert his free throw, the following calculation has to be performed:
0.4 x 100 x 1 = X
40 x 1 = X
40 = X
Therefore, Dr. Agor has a 40% chance of making his free throw.
Answer:
40%

If (a+b)= -5 and ab= -150 , find a-b
Answer:
(a-b) = -25
Step-by-step explanation:
(a+b) = -5
a*b=-150
So one of the letters have to be negative as you can only get a negative product from a positive and negative
There is probably a better way to do this, but I just plug in numbers that I think will work
So, (a*b) = -150, (-15*10) = -150
Okay that works so lets try the other one
(-15+10) = -5
This also works, so lets do the third one
(-15-10) = -25

Step-by-step explanation:
In what proportion should water and milk be mixed to reduce the price of milk from Rs 5 per liter to Rs 4 per liter?
Answer:
4:1
Step-by-step explanation:
Let us assume that the cost of water is free, that is Rs.0.
Let x represent the number of liters of milk, y represent the number of liters of water and z represent the volume of the mixture in liters, hence:
z = x + y (1)
Milk cost Rs.5 per liter, water cost Rs.0 per liter and the mixture cost Rs.4 per liter. Therefore:
5x + 0(y) = 4z (2)
Substituting z = x + y in equation 2 gives:
5x + 0(y) = 4(x + y)
5x = 4x + 4y
5x - 4x = 4y
x = 4y
x / y = 4 / 1
x : y = 4 : 1
The proportion in which the milk is to be mixed with water is 4 : 1, that is 4 liters of milk per 1 liter of water

What percent of 20 is 15?
The number after "of" goes on the bottom of the fraction and the number after "is" goes on the top.
PLEASE SOMBODY DO STEP BY STEP .
15 is 75 % of 20
20/15 = 100/75
Answer:
75%
Step-by-step explanation:
Well lets set this up.
You want to find what percent of 20 is 15.
So to do that you can make it a fraction.
The numerator is what is being divided and the denominator is what you want it divided by.
So you want 15 divided by 20
So 15 is numerator
20 is denominator.
[tex]\frac{15}{20}[/tex]
A fraction is basically a division problem so now all you need to do is divide 15 by 20.
If you do that you should get a decimal answer of 0.75
To make a decimal a percentage all you have to do is multiply it by 100.
0.75 * 100
[If you do not have a calculator on you an easy way to do this is look at how many zeros 100 has and move the decimal right that many times]
75
Now just add that percent sign and you have 75% as your answer!
If you need further assistance please don't be afraid to reach out. I hope this helps!

The number 4 is the required expression.
What is PEMDAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Let x be the required number.
And the given expression is the sum of 9 and the product of a number and -7 is -19
That means ,
9 + x × -7 = -19
Using PEMDAS,
9 - 7x = -19
-7x = -19 -9
-7x = -28
x = 4
Therefore, the required number is 4.
