4(y-2)=-0.6(y+0.3 what is the answer and how to do it
Answer:Solution for 0.3(y-2)+0.4y=0.3y-0.6 equation:
0.3(y-2)+0.4y=0.3y-0.6
We move all terms to the left:
0.3(y-2)+0.4y-(0.3y-0.6)=0
We add all the numbers together, and all the variables
0.4y+0.3(y-2)-(0.3y-0.6)=0
We multiply parentheses
0.4y+0.3y-(0.3y-0.6)-0.6=0
We get rid of parentheses
0.4y+0.3y-0.3y+0.6-0.6=0
We add all the numbers together, and all the variables
0.4y=0
y=0/0.4
y=0

What is the solution to the inequality 1 2/3 > r - 7/12
Answer:
r ≤ 2 1/4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Equality Properties
Rewriting Fractions
Step-by-step explanation:
Step 1: Define
1 2/3 ≥ r - 7/12
Step 2: Solve for r
Rewrite: 5/3 ≥ r - 7/12
Isolate r: 9/4 ≥ r
Rewrite: r ≤ 9/4
Reduce: r ≤ 2 1/4
Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.
Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0
The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2 so option 1st and 4th are correct.
What are the roots of an equation?Roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
The number of roots of an equation depends on the degree of the equation for example number of roots of quadratic equation are 2.
Given the roots
01)
x = -2
square both sides
x² = 4
x² - 4 = 0
02)
x = 2
Square both sides
x² = 4
Multiply by 4 on each side
4x² = 16
Hence "The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2".

Answer:
a. Rosemarie has 16 grandchildren.
b. Each grandchild would receive $0.50 or 50 cents.
Step-by-step explanation:
a. There are 4 sons, and each son has 4 children.
Son 1: 4 children
Son 2: 4 children
Son 3: 4 children
Son 4: 4 children
So you can find the total number of grandchildren by adding up the amount of children each of the sons have: 4 + 4 + 4 + 4 = 16
Rosemarie has 16 grandchildren.
b. If the are $8 total, and it is split equally between Rosemarie's sons, it means each son would get $2 (because $8 / 4 sons = 2).
And then each son would split it between his 4 kids. So $2 / 4 kids = $0.50
Each grandchild would receive $0.50 or 50 cents.

I need help on the whole assignmnet but particularly this question..
Answer:
1) 62.5
2) 50
3) 75
4) 100
Step-by-step explanation:
1)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.
So, [tex]1000/16=\boxed{62.5}[/tex].
2)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.
So, [tex]400/8=\boxed{50}[/tex]
3)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.
So, [tex]300/4=\boxed{75}[/tex].
4)
The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.

In the given figure find out the value of x and y ?
Given info:
all sides are equal in the given triangle
It is an equilateral triangle all angles are equal and each angle is equal to 60°Given angles are 3y° and 2x°
→ 3y° = 2x° = 60°
→ 3y° = 60° and 2x° = 60°
→ y° = 60°/3 and x° = 60°/2
→ y° = 20° and x° = 30°
Therefore, x° = 30° and y° = 20°
Answer:-
The values of x = 30° and y = 20°
Key Knowledge:-
→ If all sides are equal in a triangle then it is an equilateral triangle
In an equilateral triangle,
→ all sides are equal.
→ all angles are equal.
→ all angles are equal to 60°

Two fifth of pupils in a standard 7 class were girls.There were 27 boys in the class. ( a) how many girls were there. (b) how many peoples were there in the standard 7 class
Answer:
a. 18
b. 45
Step-by-step explanation:
The question states that 2/5 of the class are girls which means 3/5 are boys:
[tex]\frac{3}{5} = 27[/tex]
Divide this value by 3 to get the value of [tex]\frac{1}{5}[/tex]:
27 ÷ 3 = 9
Multiply this by 5 to find [tex]\frac{5}{5}[/tex], the total pupils in the class:
9 x 5 = 45
As the number of girls is [tex]\frac{2}{5}[/tex] of the total pupils:
9 x 2 = 18
So there are 18 girls in the class which has a total pupil size of 45.
Hope this helps!
Step-by-step explanation:
according to question of ⅖ are girls than ⅗ are boys
so let the number of girls be x
so,
→ ⅗ of x = 27
→ x = 27 × 5/3 = 9×5 = 45
→ x = 45
a ) 45 - 27 = 18
than no. of girls is 18.
b) thier are 45 students in total.
