Hi,
<em>Sammy has $125.75 in her savings account. She deposits $25.50 into the account each month for the next 6 months. </em>
<u>How much is in Sammy's account at the end of the 6 months?</u>
25.50 × 6 = $153
In 6 months she deposits $153 into the account.
So :
125.75 + 153 = $278.75
At the end of the 6 months Sammy has $278.75 in her savings account.
Let x be the width
2x-3= length
(2x-3)(x)=14
2x^2-3x=14
2x^2-3x-14=0
(2x- 7)(x+2)=0
x=7/2 or x=-2
Since we know that negative values cannot exist in distance, we have to take 7/2 to as the correct answer.
The width would be 3.5 yards
Length= 2(3.5)-3
=4 yards
3.5 x 4 yards is the dimension of the rectangle
Hope I helped :)
Counting by 10 is called base 10
First you can solve for b: Subtract a on both sides and get 2b=-a+10, then divide by 2 to get b by itself and get: b=-1/2a+5
Then you can plug in this equation for b in the other: This would give you: 2a+-1/2a+5=6. Then you can use that equation to solve for a and get: 1.5a+5=6, subtract 5, 1.5a=1, divide by 1.5, a=1/1.5
Then you can plug in the value of a to solve for b.
