i dont want to cheat but can anyone tell me how to do it or how to start out
Answer:
x is 13
y is 39
Step-by-step explanation:
Answer:
y= 39 x= 10
Step-by-step explanation:
congruent isosceles triangles
longer sides measure the same 13 and 13 39 and 39 ( y =39)
39/30 = 13/x
cross multiplication:
39x = 13x30
39x = 390
x=10

4 ( 4x+15)=24
Answer:
x=-9/4
Step-by-step explanation:
4(4x+15)=24 - divide both sides
4x+15=6 - move constant to the right
4x=6-15 -solve for the difference
4x=-9 - divide both sides

Carolina leaves her house and walks 6 blocks she turns and heads east 8 blocks until she reaches matties house what is the shortest distance between Carolinas house and matties house
Answer:
10 blocks
Step-by-step explanation:
Given
[tex]First = 6\ blocks[/tex]
[tex]Second = 8\ blocks[/tex] east
Required
Determine the shortest possible distance
To better explain my solution, I've added an attachment that illustrates her movement.
Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.
So, we have:
[tex]x^2 = 6^2 + 8^2[/tex]
[tex]x^2 = 36 + 64[/tex]
[tex]x^2 =100[/tex]
Take positive square root of both sides
[tex]x = \sqrt{ 100[/tex]
[tex]x = 10[/tex]

Find the value of z in the following equation.
z + 3z + 25 = 125
Answer:
25
Step-by-step explanation:
z+3z+25=125
4z=100
z=25
Answer: 25
Step-by-step explanation:
Combine like terms
z + 3z + 25 = 125
4z + 25 = 125
Subtract 25 on both sides
4z = 100
z = 25

Estimate 154 divide 7
Answer:
22
Step-by-step explanation:
The result of 154 divided by 7 will be 22.
What is the rule of division?The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.
Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.
Since the given problem is not a large division. We can solve it by breaking 154 into two parts
______
7 / 154 \ 2 2
14
---------
1 4

Therefore, 22 will come from dividing 154 by 7.

Find the real-number root.
√-3.24
Answer:

Step-by-step explanation:
So, we can say that the square root of 3.24 is 1.8 with an error smaller than 0.001 (in fact the error is 0.0000276241). this means that the first 4 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math. sqrt(3.24)' is 1.8
A box contains 4 red pencils and 6 black pencils. What fraction of he pencils are red? What fraction of pencils are black? Draw a model.
Answer:
The fraction of the pencils that are red is 4/10. The fraction of the pencils that are black is 6/10.
Step-by-step explanation:
[I can't draw you a model but I reccomend that when you do, you seperate it into 10 pieces and mark 4 as red pencils and 6 as black pencils. You could also simplify 4/10 to 2/5 and 6/10 to 3/5, but instead you'd seperate the model into 5 pieces and mark 2 as red pencils and 3 as black pencils.]
First, let's add this up so we have our denominator.
4 + 6 = 10.
Now that we know that the denominator is 10, we apply it to the question.
The box has 4/10 red pencils and 6/10 black pencils.
The box has 4/10 red pencils and 6/10 black pencils.If you were to simplify, it'd be 2/5 red pencils and 3/5 black pencils.
