2/5 of a number is -8 what is the number
Answer:
-20
Step-by-step explanation:
let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20
Answer: The number is 35
If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.
Step-by-step explanation:
Let the missing number = y
To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.
Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.
Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.
Thus,
2/5 of 14/y
2/5= 14/y
(2 x y) = (5 x 14)
(2y) = (70)
2y = 70
Since we are looking for value of y, divide both sides by the value beside y
Thus,
2y/2 = 70/2
y = 35
Therefore, the missing number is 35

For the given triangles ΔABC ≈ ΔXYZ, the length of side N is, 45/4
What is similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"
Given that,
The triangle, ΔABC
Triangle ΔABC and ΔXYZ similar,
So, ΔABC ≈ ΔXYZ
And it is known that
for similar triangles, ratio of lengths of sides are equal for similar triangles
so, AB/AC = XY/XZ
⇒ 5/8 = N/18
⇒ N = 45/4
Hence, the value of N is 45/4

Help me to find the value of x, please
Answer:
x = 4
Step-by-step explanation:
The easiest way to do this is to look at the vertical angles. (15x)º has its own vertical angle, and the part with (8x-2)º and 90º does as well.
Also, every angle will add up to 360º, which is a crucial part of the equation
Do 15x + 15x + 90 + 90 + 8x - 2 + 8x - 2 = 360
This can be simplified into this once you combine like terms:
46x + 176 = 360
Subtract 176 from 360, which will give you:
46x = 184
Divide by 46 on both sides, resulting in:
x = 4
To check the answer, plug in 4 for x:
15(4) + 15(4) + 90 + 90 + 8(4) - 2 + 8(4) - 2 = 360
60 + 60 + 90 + 90 + 32 - 2 + 32 - 2 = 360
120 + 180 + 60 = 360
360 = 360, x is 4
Hope this made sense!

Solve the system by substitution.
3x-6y=2
4x+3y=-1
Answer:
y = -1/3
x = 0
Step-by-step explanation:
3x-6y = 2 then 3x = 2+6y, x=(2+6y)/3
4x+3y = -1
substitute for x
4(2/3+2y)-6y = 2
8/3+8y-6y = 2
reduce
2y = 2-8/3
2y = -2/3
divide both sides by 2
y = -1/3
4x+3(-1/3) = -1
4x = 0
x = 0
