Answer:
Step-by-step explanation:
arithmetic sequence formula: 
where 
is the first term and 
is the common difference
Given:

Given:
⇒ 
⇒ 
Rearrange the first equation to make the subject:
a = 32 - 9d
Now substitute into the second equation and solve for
(32 - 9d) + 11d = 106
⇒ 32 + 2d = 106
⇒ 2d = 106 - 32 = 74
⇒ d = 74 ÷ 2 = 37
Substitute found value of into the first equation and solve for :
a + (9 x 37) = 32
a + 333 = 32
a = 32 - 333 = -301
Therefore, the equation is:
The answer would be 3/7
Explanation:
This question is basically asking for you to simplify 12/28. To do this, we find the GCF (Greatest Common Factor) of 12 and 28, which is 4. Then, we do 12 / 4 and 28 / 4, which gives us 3 and 7. Therefore, the answer is 3/7.
The equations standered form is y=-x^2/8-x/2-9/2
Answer:
29,160,000
Step-by-step explanation:
24,300,000x120%=29,160,000
Answer:
17 and 38
Step-by-step explanation:
x + y = 55......x = 55 - y
x * y = 646
y(55 - y) = 646
55y - y^2 = 646
y^2 - 55y + 646 = 0
(y - 17)(y - 38) = 0
y - 17 = 0 y - 38 = 0
y = 17 y = 38
ur numbers are 17 and 38
