4(x – 3) + 4 < 10 + 6x
Distribute the 4 on the left side.
4x -12 +4 < 10 + 6x
Combine like terms on the left side.
4x-8<10 +6x
Subtract the 6x from both sides.
-2x -8<10
Add the 8.
-2x <18
Divide by -2 & flip the inequality symbol (it's a math rule which states that if you multiply or divide by a negative, you must flip the inequality symbol).
x> -9
That's your final answer.
Answer:
Step-by-step explanation:
1.2307692307692.
The first step is to find the proportionality constant.
The formula is
z = kx/y
1.2307692307692 = k * 4/13 Multiply both sides by 13
1.2307692307692 * 13 = 4k
16 = 4*k Divide by 4
k = 16/4
k = 4
=================================
z = k*x/y
x = 9
y = 20
k = 4
z = 4 *9/20
z = 36/20
z = 1.8

The answer is d because all angles in parallelogram are the same
Answer:
Proton
Step-by-step explanation:
However, the atom itself is not the smallest known particle, but instead each atom is made up of three individual parts: electrons, protons and neutrons. Furthermore, protons and neutrons themselves are made up of even smaller parts called quarks.
Answer: (36 - 1) ÷ (3 + 2) + 13 = 20
Step-by-step explanation:
PEMDAS rule calls for parenthesis to be solved first, then exponents, then multiplication or division then addition or subtraction depending on which comes first in the equation.
Using the PEMDAS rule the 20 can be gotten to if the equation is expressed as follows;
(36 - 1) ÷ (3 + 2) + 13 = 20
The parenthesis will be solved first;
35 ÷ 5 + 13 = 20
The division will be done first;
7 + 13 = 20
Then the addition;
7 + 13 = 20
