Answer:
x=5
Step-by-step explanation:
Set the 2 equations equal to each other and solve for x.
11x-28=7x-8
add 28 to both sides (-8+28=20)
11x=7x+20
subtract 7x from both sides (11x-7x=4x)
4x=20
divide both sides by 4 to isolate x (20/4=5)
x=5
The Answer has to be 40 degree's
Answer:
Expressions B, D and E
Step-by-step explanation:
Here, we are to select which of the options is correct.
Let’s put in mind that they bought earn $12 per hour
x represents the number of hours Tina worked this week; the total amount of money she made would thus be x * 12 = $12x
Remembering that she made $46 overtime, the total amount of money she made that we would be $12x + 46
The total amount Tammy made, earning $12 per hour and working for y hours = $12 * y = $12y
The total amount of money both made is thus;
12x + 46 + 12y
= $(12x + 12y + 46)
Now, we have similar expressions in the question;
These are; expression B, expression D and expression E
While expression B is straightforward, the others are not
expression D is gotten by factoring out 12; 12x + 12y + 46 = 12(x + y) + 46
expression E just involved putting what each of the two earned in brackets
Price for <span>roller coaster ride:x
</span><span>Prices for the entry fee:y
</span><span>From table: for 5 rides total price is $35: 5x+y=35
for 11 rides total price is $59: 11x+y=59
</span><span>5x+y=35⇒y=35-5x
</span><span>11x+y=59
y=35-5x
11x+35-5x=59⇒6x=59-35
y=35-5x
6x=24⇒x=24/6
x=4⇒y=35-5*4
y=15
Price for entry fee is $15, </span><span>and for each roller coaster ride $4.</span>
