25 PTS <br> PLEASE HELP !!!
SIZIF [17.4K]

Answer: 1 5/7

Step-by-step explanation:

First lets simplify 2/5x1/4,

-> 8/20x5/20

-> 40/20

-> 4/2

Now lets calculate:

42÷−7−6=?

In the second fraction, the negative numerator and negative denominator cancel each other.

The equivalent equation is

42÷76=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

42×67=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

4×62×7=2414

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 14 using

GCF(24,14) = 2

24÷214÷2=127

The fraction

127

is the same as

12÷7

Convert to a mixed number using

long division for 12 ÷ 7 = 1R5, so

127=157

Therefore:

42÷−7−6=157

Solution by Formulas

Apply the fractions formula for division, to

42÷−7−6

and solve

4×−62×−7

=−24−14

A negative over a negative becomes positive

=2414

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(24,14) = 2

24÷214÷2=127

Convert to a mixed number using

long division for 12 ÷ 7 = 1R5, so

127=157

Therefore:

42÷−7−6=1 5/7

(Sorry for the 157s I meant 1 5/7)

1/3 . Abase . height

Step-by-step explanation:

Please find attached the complete question

a square pyramid is a pyramid that has a square base.

total surface area measures the total area of the surfaces of an object

the formula 1/3 x Area of the base x height is used to calculate the volume of the pyramid and not the surface area

*15 points*<br><br> I need a proper explanation please.
uranmaximum [27]
To find our solution, we first write the equation in the following form:
y = ax + b

In this formula a represents the slope, therefore:
y = - \frac{1}{5} x + b

Because the line passes through the point P(5, -7), we can fill in the coordinates of this point in the formula and we get the following:
- 7 = -\frac{1}{5} \times 5 + b
- 7 = -1 + b
Now, add up 1 to both sides and we get
b = -6
So the formula will be:
y = - \frac{1}{5} x - 6

Bringing x to the other sides gives us:
\frac{1}{5} x + y = -6
Finally we multiply by 5 to get our standard form (and therefore our final answer):
x + 5y = -30
Hence, the answer is D.
