Answer:
x=32 so one solution only
Step-by-step explanation:
6(x-8)+10=5x-6
6x-48+10=5x-6
6x-38=5x-6
x-38=-6
x=32
Therefore, the equation only has one solution which is x=32
Answer:
7th week
Step-by-step explanation:
Let us represent the number of weeks as x
Jill begins the summer with $500 in her savings account. Each week, she withdraws $20.
$500 - $20× x
500 - 20x
Her brother, Sam,starts the summer with $150 in his account. He adds $30 to his account each week.
$150 + $30 × x
150 + 30x
At what week will both Jill and Sam have the same amount in their account?
We solve this be Equating both Equations together
Jill = Sam
500 - 20x = 150 + 30x
Collect like terms
500 - 150 = 30x + 20x
350 = 50x
Divide both sides by 50
50x/50 = 350/50
x = 7 weeks
Therefore, at the 7 week, Jill and sam would have the same amount in their accounts
Ratio of height of the flag pole to the length of its shadow = 40:9.6 = 25:6
Ratio of height of the building to the length of its shadow = x:48 = 25:6
x/48 = 25/6
x = (48 x 25)/6 = 1200/6 = 200
Therefore, the height of the building is 200 feet.
If 360 is 2/3 of the full price on a saw then your equation should look like this:
x is your unknown full price of the saw. Just solve for x now.
This means that the full price is $540.
Hope this helps!
