Answer:
x = 30
Step-by-step explanation:
-2x + 10 +4x=70
-10 -10
-2x + 4x = 60
2x = 60
/2 /2
x = 30
Answer:
x=30
Step-by-step explanation:
combine like terms to get
2x+10=70
then subtract 10 from both sides
2x=60
then divide both side by 2

The solution for the scientific notation will be 3.6 x 10⁻¹¹.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the scientific notation is calculated as below,
E = (4x 10⁻⁵) (9x 10⁻⁵)
E = ( 4 x 9 ) ( 10⁻⁵ x 10⁻⁵ )
E = 36 x ( 10⁻¹⁰)
E = 3.6 x 10⁻¹¹
Therefore, the solution for the expression will be E = 3.6 x 10⁻¹¹.

Triangle ABC is similar to triangle XZY. Find the missing side x using proportions ( PLEASEE HELP ASAP)
Answer:
x=70º
Step-by-step explanation:
Triangle ABC, A/C=50º, B/C=40º
40º+50º=90º
Triangle XZY, Y/Z=20, Y/X=x
Since it is a right triangle it will add up to 90º.
So 90º-20=70
The missing angle x is 70
x= 70
The length of the unknown side of the triangle XYZ is 25 units.
What is similarity of triangles?
Two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.
Given is Triangle ABC which is similar to triangle XZY.
Since both the triangles are congruent to each other, their corresponding sides will be in equivalent ratios. Therefore, we can write-
BC/YZ = AC/YX
40/20 = 50/x
x = (50 x 20)/40
x = 50/2
x = 25
Therefore, the length of the unknown side of the triangle XYZ is 25 units.

Jenny watched a movie about aliens who never stop growing. Every alien is 10 centimeters tall at birth and grows exactly 8 centimeters each year. Let y represent the number of years since birth and h represent the alien's height in centimeters. Complete the equation that represents the relationship between y and h. y h 4 42 5 50 6 58 7 66
Answer:
h = 10 + 8y
Step-by-step explanation:
Given that :
Height of ght if all alien at birth = 10cm
Growth rate per year = 8 cm
Let:
y = number of years since birth
h = alien's height in centimeter
Relationship between h and y
h = Initial height + (growth rate per year*number of years)
h = 10 + 8y

Step-by-step explanation:

A building casts a 33 m shadow when the Sun is at an angle of 26. to the vertical. How tall is the building, to the nearest meter? Use a trigonometric ratio to find the distance F E.
so basically we just us do this
tan(26)=33/FE
Multiply to get rid of fraction
tan(26)FE=33
divide to get FE alone
FE = tan(26) * 33
FE=16.0951m
so it should be 16.0951m
