Answer:
8u + 9v
Step-by-step explanation: This would be the expression that can determine how much Jay earns within a week because it expresses both kinds of income.
1 steak costs $9.99
2 steaks cost 2*9.99 = $19.98
This is before tax is applied
Apply the 6% tax to get
6% of 19.98 = (6/100)*19.98 = 0.06*19.98 = 1.1988
which rounds to 1.20 (rounded to the nearest penny)
The sales tax is therefore $1.20
Add this to the previous total (19.98) and we get a grand total of 19.98+1.20 = 21.18 which is the final cost (with tax included)
note: we can multiply 19.98 by the value 1.06 to get 19.98*1.06 = 21.1788 and that rounds to 21.18; so it's a different route to the second answer
Answer:
<h2><em><u>
B or the second one</u></em></h2>
Step-by-step explanation:
This is because you have the equation of 2(2/5x + 2).
When you simplify it you have to first do the parenthesis.
So, 2 * 2/5 = 4/5. This is because 2/1 *2/5 is 4/5.
Then you have to do 2*2. This is equal to 4.
Put them together. So it will be.
<h2><u><em>
4/5x + 4.</em></u></h2>
Answer:
Steve's lunch is $8.00
Step-by-step explanation:
First you have to make a formula for this almost.
s= Steve's lunch
y= your lunch
s= y-3
s+y-19
then plug in s
y-3+y=19
Then simplify 2y-3=19
Add the three to both sides 2y=22
Divide both sides by 2 y=11
Last plug y into one of your formulas
s=Y-3
s=11-3
s=8

Answer:
Step-by-step explanation:
A = L * W
A = 99
L = 2w + 7
now we sub
99 = (2w + 7)(w)
99 = 2w^2 + 7w
2w^2 + 7w - 99 = 0
(2w - 11)(w + 9) = 0
2w - 11 = 0
2w = 11
w = 11/2
w = 5 1/2 ft (or 5.5 ft) <==== width is 5 1/2 ft)
L = 2w + 7
L = 2(5.5) + 7
L = 11 + 7
L = 18 ft <====== length is 18 ft
