The first one is 7.4 . 39/5=7 and 4 change so 7.4 . The second one is 1.67 . 5/3 is 1.6 repeated and rounded to the nearest houndredth is 1.67
Answer:
See below:
Step-by-step explanation:
Take the difference between y values of any two values and divide by difference in corresponding x values
for example, 1: 66-50/4-1=16
2. 36-30/8-6= 6/2=3
3. 63-56/8-7= 7/1 = 7
4. 100-78/9-7= 22/2 = 11
you can choose any two points, not just the two I used.
If you would like to solve the equation 3 3/4 * a + 3 + 6 = 87, you can do it using the following steps:
3 3/4 * a + 3 + 6 = 87
15/4 * a = 87 - 3 - 6
15/4 * a = 78 /*4/15
a = 78 * 4/15
a = 104/5
a = 20.8
The correct result is 20.8.
