7x - 5y = 21....(4,?)...so sub in 4 for x and solve for y
7(4) - 5y = 21
28 - 5y = 21
-5y = 21 - 28
-5y = - 7
y = 7/5
check..
7(4) - 5(7/5) = 21
28 - 35/5 = 21
28 - 7 = 21
21 = 21 (correct)
the other coordinate is 7/5......(4,7/5)
Answer:
$4150
Step-by-step explanation:
Given data
Salary= $2500
Commission= 10%
Sales= $16500
Let us find the amount of the commission made
=10/100*16500
=0.1*16500
=$1650
Hence the total amount made for the month is
=commission + salary
=1650+2500
=$4150
None of the above because it will be 3.2 or -3.2
Answer:
The length is 30 cubic yards.
Step-by-step explanation:
To find volume you use equation V=LxWxH
Since we already know the height, width, and volume we can input them into the equation.
18,720=L x 24 x 26
As you can see, the length is still unknown.
To figure it out though, you can multiply the height and width of the prism,
24 x 26 = 624
And then divide the volume, 18,720 by it.
18,720/624 = 30
Thus, your length is 30 cubic yards.
Answer:
When you multiply radical expressions you multiply the numbers under the radical symbols.3–√×7–√=21−−√
When you add radical expression you CANNOT add the numbers under the radical symbols.
3–√+7–√≠10−−√
