Answer:
= 8
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = 8 and r = - 24 ÷ 8 = - 3, thus
= 8
Step-by-step explanation:
3) y=4x-2
since x is already 3, simply substitute
y= 4(3)-2
y=12-2
y=10
second pair for number 3 is 10
4) y=16+7x
since y is already 37, simply substitute
37=16+7x
37-16=7x
21=7x
x=21/7
x=3
second pair for number 4 is 3
In order to eliminate one of the variables, subtract one of the equation from the other equation.
<h3>How to eliminate one of the variables?</h3>
Given these equations:
o + 3s = 76 equation 1
o + s = 36 equation 2
Where:
o = number of orange juice bought
s = number of sandwiches bought
In order to eliminate one of the variables, subtract equation 2 from equation 1. The result is :
2s = 40
s = 20

First you need to put this into a fraction. 15/60. Now you need to simplify it. 15/5 and 60/5 equals 3/12. Now simplify again to get 1/4. She has hit 1/4 of the balls hit
