i reccomend not getting it because thats a bad membership
3x+2(5x-3)=7
3x+10x-6=7
13x-6=7
13x=13
x=1
Answer:
QR = 1
Step-by-step explanation:
PR = PQ + QR
PR = x + 19
PQ = 9
So now put what you know in the equation above.
PR = 9 + 2x + 19
PR also equals x + 19
so
x + 19 = 9 + 2x + 19
x + 19 = 2x + 28
19 - 28 + x = 2x
-9 + x = 2x
-9 = 2x - x
-9 = x
===================
QR = 2x + 19
QR = 2*-9 + 19
QR = -18 + 19
QR = 1
This really is kind of a nasty question. You don't expect to get a minus number of x.
Answer:

Step-by-step explanation:
Let's set up a proportion using the following setup:

We know that the florist can arrange 4 in 92 minutes.

We don't know how many the florist can arrange in 207 minutes, so we say x arrangements can be completed in 207 minutes.


Solve for x by isolating it on one side of the proportion.
x is being divided by 207. The inverse of division is multiplication. Multiply both sides of the proportion by 207.




The florist can arrange <u>9 arrangements</u> in 207 minutes.
Answer:
The answer of this question is FALSE.
