Step-by-step explanation:
-2 (4a + 4b) + 5a > -35
-8a -8b + 5a > -35
-3a -8b > -35
for a
-3a > -35 + 8b
a < -35 + 8b ÷ -3
a < 35 - 8b ÷ 3
for b
-3a - 8b > -35
-8b > -35 + 3a
b < -35 + 3a ÷ -8
b < 35 - 3a ÷ 8
Answer:
10,000
Step-by-step explanation:
100x100=10,000
The two hundreds in this equation have a total of 4 zeros, so you just put those 4 zeros at the end of your answer.
After that, multiply 1 and 1.
That should be 1.
After that, put the 4 zeros behind the 1.
Your answer should be 10,000.
Hope this helps!
Answer:
Equation is
0.125 gallons of the 35% acid solution Eli should add.
Step-by-step explanation:
Given : Eli wants to combine 0.5 gallon of a 10% acid solution with some 35% acid solution to make a 15% acid solution.
To find : Equation can you use to determine how many gallons of the 35% acid solution Eli should add?
Solution :
Let x be the gallons of the 35% acid solution.
According to question,
For 0.5 gallon of a 10% acid solution =
For x gallon of a 35% acid solution =
For (0.5+x) gallon of a 15% acid solution =
The equation form is
Solving the above equation,
Therefore, 0.125 gallons of the 35% acid solution Eli should add.
The equation is
-8x-14y=28
Y= (0,-2)
X=(-7/2,0)
2x-7y=14
Y=(0,-2)
X=(7,0)
Answer:
1) geometric sequence
2) geometric sequence
3) arithmetic sequence
Step-by-step explanation:
First two sequences are geometric sequences
The geometric sequences are sequences where each term is made by multiplying the preceding term by the same value
In here the first sequence is multiplied by 4
the second one is multiplied by -3
The third one however is set by adding 5 to the number each time
So the third one is an arithmetic sequence
