4x+30=40

What you would do is subtract 30 from 30 and 40 which would give you 10 and then what you would do is divide the 10 by 4 to get 2.5.  Therefore X=2.5.  And to check your work you would plug in 2.5 in place of X and the answer to that equation should be 10.

PQRS is a parallelogram and T is the mid point of PQ if ar PTRS=24 cm^2, find the area of PQR​
Lady_Fox [76]

Answer:

24 sq cm

Step-by-step explanation:

According to theorem of area if parallelogram and triangle, if the triangle and a parallelogram lie between two parallel line and their base is same then, the area of triangle is half of the area of the parallelogram. so here the parallelogram PTRS and the triangle PTR lie between same parallel lines PT and RS and base is also same PT. so area of PTR is 12sq cm. Again, triangles PTR and TRQ lie between same parallel lines PQ and SR and same base PQ. so their area also same that is 12 sq cm. Now, area of PQR = area of PTR + area of TRQ = 12 + 12 sq cm = 24 sq cm.

Olve for x. 3(3x - 1) + 2(3 - x) = 0 x = 3/7 x = -3/7 x = 1/3 x = -1/3
zloy xaker [14]

<u>Answer:</u>

x = -3/7

<u>Step-by-step explanation:</u>

We are given the following equation for which we have to solve for x:

3(3x - 1) + 2(3 - x) = 0

So we will start by expanding the equation by multiplying the common factor with the brackets to get:

9x-3+6-2x=0

Arranging the like terms together (variables on one side of the equation and constants on the other side) to get:

9x-2x=3-6\\\\7x=-3\\\\x=-\frac{3}{7}

Therefore, x = -3/7.
