Answer:
x=4
y=5
Step-by-step explanation:
inform me if u cant open the image
50 you don't need to do anything else it already is approximate
1) 24 / 18 = 1.33 and 28 / 21 = 1.33
so the exchange rate must be 1.33
2)1080 - 720 = 360
360 / 12 = 30
so the change is $30 per year
3) The slope would be a straight line and the y- intercept would be +30
Hope this helps! :)
Answer:
Pauline used the wrong base to compute the discount.
Step-by-step explanation:
Pauline is wrong because she figured the discount on £126 instead of the original cost. The actual discount is figured on the original cost, so £126 represents 60% of that cost.
The original cost is perhaps best found by dividing the sale price by 0.60 to get £210. Then we can check by computing the discount as 40% of £210, or £84, leaving a sale price of £210 -84 = £126.
Answer:
1 < x < 19
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
We are given the measures y=10, z=9. The third side must satisfy:
10 - 9 < x < 10 + 9
1 < x < 19
