y = ( 3 * x ) - 2.

This is because the card costs for 3 $ and should be multiplied by the number of total cards she buys in that particular day. So 3 * x.

Now as she has got a 2$ off coupon, whatever the total is she gets 2 dollars off on that price. So we will subtract 2 at that time. FInally all this summed up would be equal to y.

Tyrell is going to be use ASA to prove that PQR=SQR
motikmotik

Presumably our goal is to show PRQ=SRQ, PQR=SQR and QR=QR for ASA.

A. QR=QR is the reflexive property; things are congruent to themselves, TRUE

B. We need to prove that, but it doesn't have anything to do with the symmetric property.

C. PQ=SQ isn't something we'd need to show for our ASA proof

D. Again, not the symmetric property.

Answer: A

the length of a rectangle is 5 minutes longer than its with if the perimeter of the rectangle must be at least 34 units what are
stealth61 [152]

Answer:

w ≥ 6

l ≥ 11

Step-by-step explanation:

The perimeter of a rectangle is equal to P = 2l+2w where l=length and w=width. Here the length is 5 feet longer than the width or 5+w. This means the width is w. Substitute P = 34, l=5+w and w into the perimeter equation. Then solve for w.

34 ≤ 2*(5+w) + 2w

34 ≤ 10+2w+2w

34 ≤ 10+4w

24 ≤ 4w

6 ≤ w

This means the width must be at least 6 so the solution is w ≥ 6.

To find the length substitute 6 into l ≤ 5+w.

l ≤ 5 + 6

l ≤ 11

The length is l ≥ 11.

Solve for u. 20 − (u · 0.9) = 4.7
alina1380 [7]

Answer:

20 - 0.9u = 4.7

-0.9u = 4.7 - 20

-0.9u = -15.3

Divide both sides by - 0.9

u = 17

Hope this helps.
