Answer:
6 quarters and 6 dimes
Step-by-step explanation:
since there is 6 quarters it would be 6x$.25 which is $1.50, and each dime is worth 10 cents so 6x$.10 is $.60, and $1.50+$.60=$2.10
Answer:
These parallel lines cross 1 line. Because they are parallel they will form the same angles on that line. Therefore, x+50 = 3x-100 since those angles are corresponding angles made by a pair of parallels.
To find x we need to find what value of x gives the same answer for 3x-100 and x+50 since those 2 angles are equal.
x+50 = 3x-100 - now all we need to do is solve for x:
x+50 = 3x-100
50=2x-100
150=2x
75=x
x=75
Step-by-step explanation:
Answer:
square roots
quadratic formula
factoring
complete the square
Step-by-step explanation:
1. In the first one, we can divide both sides by -2 and then square root it, getting x^2 = -98 so x = 7i \sqrt(2).
2. We can use the quadratic formula to find out the second one.
3. We can factor 4x^2 - 21x - 18 = 0 and get (x + 6)(4x - 3).
4. In the last one, we can complete the square, getting (x + 9)^2 + 16.
The projected sales for the next day is $6844, 15% higher than the sales of the previous day.
Day 1 = 4500
Day 2 = 5175
Day 3 = 5951
Day 2 / Day 1 = 5175 / 4500 = 1.15 x 100% = 115%
Day 3 / Day 2 = 5951 / 5175 = 1.15 x 100% = 115%
Based on the above computation, projected sales of the next day is 15% higher than the sale of the previous day.
Day 4 / Day 3 = x / 5951 = 1.15 x 100% = 115%
x / 5951 = 1.15
x = 1.15 * 5951
x = 6843.65 rounded up to the nearest one 6844
To check:
Day 4 / Day 3 = 6844 / 5951 = 1.15 x 100% = 115%
