Answer: 8000 points last week.
Step-by-step explanation:
If she has increased by 75% in a week to get 14000 points then we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.
175% * x = 14000
1.75x =14000 Divide both sides by 1.75
x= 8000
So she had 8000 points last week.
Check:
175% * 8000= 14000
1.75 * 8000 = 14000
14000 = 14000

Answer:
the relationship between a prism and a pyramid with equal bases and heights is the volume of the prism is three times the volume of the pyramid.
Step-by-step explanation:
Answer: 140 ml
Explanation:
let x be the original amount of water
x - 15% = 119
But x = 100% because it’s the original
=> 100% - 15% = 119ml
85% = 119ml
Find the amount of water in 15%:
85% = 119
15% = y
=> 85/15 = 119/y
Cross multiply:
85y = 15 x 119
85y = 1785
y = 1785/85
y = 21
But y = 15% therefore, 15% = 21ml
Back to our equation:
x - 15% = 119ml
x - 21ml = 119ml
x = (119 + 21)ml
x = 140ml
Therefore, the original amount of water is 140ml
The y- intercept of this equation is 4/1=4.00000
Explanation: y tells us how far up the line goes Notice that when x = 0 the value of y is 4/1 so this line "cuts" the y axis at y= 4.00000
