Let’s designate the number of banana splits sold as x. That means the number of sundaes sold is x + 8.
Now if we put this into an equation, also keeping in mind their costs, we get:
3(x) + 2(x + 8) = 156
Now to solve for x:
3x + 2(x + 8) = 156
3x + 2x + 16 = 156
5x = 140
x = 28
That means you’ve sold 28 banana splits and 36 sundaes! :)
To begin lets say year one the population is 2,000
assume this in percent we can say that 2,000=100%
at the end of this year the population will have grown by 4% meaning that
100%+4% will be the new population =104%
but we know that 100%=2,000 so what about 104%=X?
so (104*2000)/100=2,080
So year 1 the population will have grown by 80 people amounting to 2080 people.
Now do it manually year by year until we reach the 15th year. i will help you up to year 3
2nd year= (2080*104)/100=2163.2
3rd year= (2163*104)/100=2249.728

Answer:
Graph F
Step-by-step explanation:
Given
x + 3 < 7 ( subtract 3 from both sides )
x < 4
Since x is less than 4 then this is indicated by an open circle at 4 on the number line with the arrow pointing to the left as shown on graph F
Answer:
6 pounds of fertilizers are needed for garden area of 180 square foot.
Step-by-step explanation:
Let 'x' pounds of fertilizers be needed for 180 square foot garden.
Given:
4 pounds of fertilizer needed for an area of 120 square foot.
The area of the garden given is 180 square foot.
Now, as per question:
4 pounds of fertilizer is equivalent to an area of 120 square foot.
Therefore, 'x' pounds of fertilizer is equivalent to an area of 180 square foot.
Applying proportion and cross multiplying method, we get:
x 4
_ = _
180 120
120x=4 x 180
120x= 720
x = 720
_
120
x=6 LBS
Therefore, 6 pounds of fertilizers are needed for garden area of 180 square foot.
