Airida [17]3 years ago

Answer:

m∠PQR = 133

Step-by-step explanation:

∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.

3x - 5 + x + 1 = 180

4x - 4 = 180

4x = 184

x = 46

Now we simply substitute 46 in for x:

3(46) - 5 = 133

Help with volume all help is appreciated :)
Lina20 [59]

Answer:

It would be 0.41 ft^3

Step-by-step explanation:

Alright, to start, lets get the volume of the entire cinder block and the holes within it.

1.31 * 0.66 * 0.66 ---> 0.5706...

Next with the holes, they are both 0.33 wide, 0.39 long, and just as tall at 0.66 feet.

0.33 * 0.39 * 0.66 ---> 0.0849...

Since there's two of them: 0.1698...

To finish it, subtract the hole volume from the total volume;

0.5806 - 0.1698 = 0.4108

Rounds to <u>0.41 ft</u>^3

Solve the system of equations two ways: 3x+y=5 and x-2y=4 A) using substitution B) using elimination
Vedmedyk [2.9K]
A. solve for 1 variable
let's solve for x in 2nd equation
add 2y to both sides
x=2y+4
sub 2y+4 for x in other equation
3(2y+4)+y=5
6y+12+y=5
7y+12=5
minu12 both sides
7y=-7
divide 7
y=-1
sub back
x=2y+4
x=2(-1)+4
x=-2+4
x=2
(2,-1)


B. eliminate
eliminate y's
multiply first equation by 2 and add to first

6x+2y=10
<u>x-2y=4 +</u>
7x+0y=14

7x=14
divide by 7
x=2
sub back
x-2y=4
2-2y=4
minus 2
-2y=2
divide -2
y=-1
(2,-1)



(2,-1) is answer
