Answer:

d=2

Step-by-step explanation:

Let's solve your equation step-by-step.

3+4.5(2d−3)=7.5

Step 1: Simplify both sides of the equation.

3+4.5(2d−3)=7.5

3+(4.5)(2d)+(4.5)(−3)=7.5(Distribute)

3+9d+−13.5=7.5

(9d)+(3+−13.5)=7.5(Combine Like Terms)

9d+−10.5=7.5

9d−10.5=7.5

Step 2: Add 10.5 to both sides.

9d−10.5+10.5=7.5+10.5

9d=18

Step 3: Divide both sides by 9.

The expressions given represent the measures of the acute angles of a right triangle Find the measure of each acute angle.

olasank [31]

Answer:

30, 60

Step-by-step explanation:

The sum of a triangles angles should be 180.

Subtract 90 because it's a right triangle.

180 - 90 = 90

Now we know the sum of the other angles should be 90.

x + 2x = 90

Solve for x.

3x = 90

x = 30

Now you substitute 30 for x.

(30), 2(30)

30, 60

A group of 6p people are renting a vacation house together the price of the rental is 3p to the 2nd power if they split the cost

Tanya [424]

So we just do
cost/number of people=cost per 1 person
so
(6p)/(3p^2)
remember that you can split it up and make ones
$\frac{6p}{3p^{2}}$ = $\frac{6}{3p}$ times $\frac{p}{p}$ = $\frac{2}{1p}$ times $\frac{p}{p}$ times $\frac{3}{3}$ = $\frac{2}{1p}$ times 1 times 1=2/p

easy way is
remember that
(x^m)/(x^n)=x^(m-n)
so
(6p)(3p^2)=6/(3p=2/p=2p^-1

each member pays 2/p

I rlly need help with this question! pls help and explain..thxs

GarryVolchara [31]

Answer:

Step-by-step explanation:

Recall these rules of logs: log a + log b = log (ab), and log a^b = b log a

Then 3 log q = log q^3 and 6 log v = log v^6, and

log q^3 + 6 log v becomes log q^3 * v^6

Now rewrite this using b as the base:

log q^3 * v^6
