A. 3

First, simplify the equation. (x means the same thing as the symbol)

19 + x = 22

Subtract 19 from both sides of the equation.

x = 22 - 19

x = 3

There’s the answer!

Write log8 3 as a logarithm of base 5.
valina [46]
The answer is <span>2) (log5)3/(log5)8
</span>
We will use the change-of-base formula: log_a(x)= \frac{log_b(x)}{log_b(a)}

So, if we want to write <span>log8 3 as a logarithm of base 5, </span> in these example a = 8, x = 3, b = 5:
log_8(3)= \frac{log_5(3)}{log_5(8)}

Two cans each hold 750ml by how many ml is their total volume less than 1.8 liters
Oksi-84 [34.3K]

If two cans hold 750ml ,then their voLume is 0.3 liters less than 1.8 liters.

Given volume of two cans being 750 ml each.

We are required to calculate the quantity in liters of how much the volume of two cans less than 1.8 liters.

Volume is the quantity of substance a container can hold in its capacity.

So volume of cone means quantity of liquid cone can hold if fully filled.

Volume of first cone=750 ml

Volume of second cone=750 ml

Total volume=750+750

=1500 ml

1 liter= 1000 ml

so 1500 ml will be equal to 1500/1000

=1.5 liter

We are required to do comparison with 1.8 liters.

Difference =1.8-1.5

=0.3 liters.

Hence two cans have 0.3 liters less than 1.8 liters.

What polynomial should be subtracted from the polynomial y^2–5y+1 to get the difference equivalent to:
Kaylis [27]

Good evening

Answer:

<h2>-3y² − 4y - 6</h2><h2 />

Step-by-step explanation:

______________________

y² – 5y + 1 − P = 4y² – y + 7

then

P = y² – 5y + 1 − (4y² – y + 7)

then

P = y² – 5y + 1 − 4y² + y − 7

then

P = (y² – 4y²) − (5y − y) + (1 − 7)

then

P = -3y² − 4y - 6
