Answer:

The value of T is 55°

Step-by-step explanation:

Using the theorem of parallel and equality,the angle of unknown angle equals to opposite one.

Or at least if you noticed,that angle is perpendicular,then 35+90=125;

180-125=55°

Isolate I for the literal equation V = IR

Anit [1.1K]

In order to isolate any term from an equation we need to clear out any different variable or numbers different from the one we want

$V=IR$

in this case I is being multiplied by R, so we need to do the opposite which is divide in order to eliminate

$V=\frac{IR}{R}$

But since this is an equality we must do it on both sides so de equation does not get altered

$\frac{V}{R}=\frac{IR}{R}$

Then we simplify the equation

$I=\frac{V}{R}$

There are 740 tickets purchased for a Major League Baseball game. The lower reserved tickets cost $9.50 and the upper reserve co

artcher [175]

375 lower reserved tickets were purchased and 365 upper reserved tickets were purchased

Step-by-step explanation:

Let x be the number lower reserved tickets

and

y be the number of upper reserved tickets

Then according to given statements

$x+y = 740\ \ \ \ Eqn\ 1\\9.50x+8y = 6482.50\ \ \ \ Eqn\ 2$

From equation 1:

$x = 740-y$

Putting in equation 2

$9.5(740-y)+8y = 6482.50\\7030-9.5y+8y = 6482.50\\7030-1.5y = 6482.50$

Subtracting 7030 from both sides

$7030-7030-1.5y = 6482.50-7030\\-1.5y=-547.5$

Dividing both sides by -1.5

$\frac{-1.5y}{-1.5} = \frac{-547.5}{-1.5}\\y = 365$

Putting y = 365 in equation 1

$x+365 = 740\\x = 740 - 365\\x = 375$

Hence,

375 lower reserved tickets were purchased and 365 upper reserved tickets were purchased

How is the distributive property used to expand expressions? provide an example

Pepsi [2]

Yes the distributive property is used to expand expressions, but it is also used to make it simpler.
For an example

3(x+4) + 3(y-8)
This is the same thing as
3x + 12 + 3y -8
