We know that ratios can be shown with both fractions and colons.
20:705
or
It also looks like we can simplify this by dividing by 5.
20/5 = 4
705/5 = 141.
This means that for every 4 teachers, there are 141 students.
The ratio for teachers to students is:
4 : 141
The sum of the angles in a triangle is 180°, If I remember correctly.
Mutiply the bracket by -2
(-2)(2y)=-4y
(-2)(-3)= 6
4y^3-4y+6+y
4y^3-4y+y+6 ( combine like terms)
4y^ 3-3y+6
Answer: 4y^ 3-3y+6
Answer:
(-1, 4)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
10x + 6y = 14
-x - 6y = -23
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Add 2 equations together: 9x = -9
- Divide 9 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: -x - 6y = -23
- Substitute in <em>x</em>: -(-1) - 6y = -23
- Multiply: 1 - 6y = -23
- Subtract 1 on both sides: -6y = -24
- Divide -6 on both sides: y = 4
Answer:
ok
Step-by-step explanation:
ok so the sum mustbe 36
and as this is a parallelogram that means opposite angle are the same and so one of the is 125that means that the opposite is 125 too, the sum is 250
360-250=110 and as one of the side must sum up to the half of 110 which is 55 and substract (55-22=33)
4=33
so is 5 =33
6=22
