(4×(4 + 3)) - 3 = (4×7) - 3 = 28 - 3 = 25
((7 - 5) ÷ 1/2) × 2 = (2 ÷ 1/2) × 2 = (2 × 2) × 2 = 4×2 = 8
(5.4 + 3) × (6 - 2) = 8.4 × 4 = 33.6
(9 ÷ 3 + 6) × 3 = (3 + 6) × 3 = 9×3 = 27
(4 + 3.2) × ((9 - 2) + 2.5) = 7.2 × (7 + 2.5) = 7.2 × 9.5 = 68.4
remember 2 things :
1. first priority for the sequence of operations is defined by brackets. second priority are multiplication and division (both are on the same level, and you can do them either way). and only third priority is addition and subtraction (they come last, and if you keep the "-" signs with the numbers, you can do them also in any sequence among each other : a - b = -b + a).
2. when you divide by a fraction, then this is the same as multiplying with the upside-down version of that fraction.
a / 1/b = a × b/1 = a × b

One just needs to go to his/her calculator and solve it
Answer:
0.04566210...(8-digit repeat)
Step-by-step explanation:
The quotient of 6 ÷ 131.4 is shown in the attachment. The remainder at the bottom matches the original dividend, so the quotient will be repeating:
[tex]\dfrac{6}{131.4}=0.\overline{04566210}[/tex]
The division process starts by rewriting the problem to integer division:
60/1314
(If you like, you could further reduce this to 10/219 by removing a common factor of 6 from numerator and denominator.)
At each stage, the quotient digit is multiplied by the divisor and the result subtracted from the dividend to get a new dividend. Careful attention to the vertical alignment of digits will help ensure that quotient digits have their proper place value.

Step-by-step explanation:

the values of q decrease as the values of p increase.
this indicates an inverse relationship between the quantities, that is
q = [tex]\frac{k}{p}[/tex] ← k is the constant of variation
to find k use any ordered pair from the table.
using q = 16 when p = 3 , then
16 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
48 = k
q = [tex]\frac{48}{p}[/tex] ← equation of variation
(4)
the values of q increase as the values of p increase.
this indicates the quantities are in direct variation, that is
q = kp ← k is the constant of variation.
to find k use any ordered pair from the table.
using q = 2 when p = 6 , then
2 = 6k ( divide both sides by 6 )
[tex]\frac{2}{6}[/tex] = k , that is
k = [tex]\frac{1}{3}[/tex]
q = [tex]\frac{1}{3}[/tex] p ← equation of variation

What is solving inequalities
Answers
An inequality is a comparison of expressions by either "less than" (<), "less than or equal to" (<=), "greater than" (>), or "greater than or equal to" (>=). Note that Html does not support the standard symbols for "less than or equal to" and "greater than or equal to", so we use <= and >= for these relations.

C: ABC approx. equal to EDC (I'm not 100% sure on this one, but it makes most sense.)
I can't help you with number four, I'm sorry. I hope someone else comes along and helps with that!
Step-by-step explanation:
The symbol being used means "approximate equality" meaning that the two angels are alike. So in A, the two sides on the shapes are both 5 cm. On B, since it is half of that side, it would be half of five, making it 2.5 cm. For C, the middle letter is the one touched second. Therefore when you draw the shape it makes the most sense that it's ABC approx. equal to EDC. Not to mention that ABC and the next angel has to match, so since the C is last, it also matches in that spectrum.
For D, I don't know the terminology, I'm sorry.

Carl or felipa ( I need a explanation aswell ) And I’ll give thanks and brainliest!!!!
Answers
Answer:
Carl is incorrect, he didn't write an equivalent expression and he didn't use the distributive property in the equation.
Step-by-step explanation:
When solving equations, we use PEMDAS
P = Parenthesis
E = Exponent
M = Multiply
D = Divide
A = Add
S = Subtract
So lets solve the equation then:
6 - 4 (3 - 6x) + 12x
Use the distributive property to multiply −4 by 3 and -6x
6 - 12 + 24x + 12x
Subtract 12 from 6 to get −6
-6 + 24x + 12x
Combine 24x and 12x to get 36x
-6 + 36x
So, -6 + 36x is the answer
And the reason why Felipa is correct, is because Felip wrote an equivalent expression, she correctly multiplied -4 (3 - 6x) before adding or subtracting and she combined like terms correctly.
The reason why Carl is incorrect, is because he didn't write an equivalent expression and he didn't use the distributive property in the equation.
