Answer:
Step-by-step explanation:
<u><em>Note:</em></u><em> It seems typo in the question. 5% should read 59.</em>
Let 3 credit courses = x, 4 credit courses = y
<u>As per given we have following equations:</u>
<u>Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:</u>
- 4(x + y) - (3x + 4y) = 4(18) - 59
- 4x + 4y - 3x - 4y = 72 - 59
- x = 13
The answer is 13
Correct choice is A
1.75
4 x 1.75 = 7 so that is the answer
Let L and W be the length and width of the given rectangle, respectively. Perimeter is calculated through the equation,
P = 2L + 2W
Substituting the perimeter,
36 = 2L + 2W
Simplifying,
18 = L + W
The area is calculated by multiplying the length and width as below,
A = 80 = LW
Substituting the expressions,
80 = (L)(18 - L)
The value of L from the equation is 8. With this, the value of W is equal to 10.
Therefore, the dimensions of the rectangle are 8 m by 10 m.
Deena drove:
585 miles/9 hrs
....which means
her average rate was:
65miles/hour
whereas
Kristen drove:
605 miles/11 hrs
....meaning
her average rate was:
55 miles/hour
Therefore, Deena drove at a faster rate than Kristen
