slope intercept form - (y = mx + b)
slope (m) is (3/2) So, y = 3/2x + b
To find b you plug in the x and y value (2,7)
7 = 3/2 × 2 + b
Isolate x on one side by finding the value of 3/2 × 2 which is 3.
Subtract 3 from both sides which leaves you with 4 = b, so the value of b is 4
Now the slope intercept form is (y = 3/2x + 4)
You want the minimum of the solutions to
x + y = 24
7x - y = 16
There are many ways to solve these equations. Adding them together, you get
8x = 40
x = 5
Since this value is less than 12, it is the smaller number. The smaller number is 5.
Answer:
Enrollment at walnut junior = 142
Enrollment at walnut high = 710
Step-by-step explanation:
Let :
Enrollment at walnut junior = x
Enrollment at walnut high = 5x
Total enrollment in both schools = 852
Mathematically ;
x + 5x = 852
6x = 852
x = 142
5x = 142 * 5 = 710
Hence,
Enrollment at walnut junior = 142
Enrollment at walnut high = 710
Answer:
<em>Tommy earned $55</em>
Step-by-step explanation:
<u>Proportions</u>
Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.
The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.
Tommy raked 5 hours, so he earned 5*$11 = $55
Tommy earned $55
I had to draw this on paper to figure it out....4 angles measure 122.....and 4 angles measure 58
