Step-by-step explanation:
y =2×2+3x-1and x + y =1y= -2×2+3x-7 and x+y=-2x3x-1and x+y =-1
Answer: 14
Step-by-step explanation:
Here are the steps to answer this question:
1. Find the denominator. Since there is 8 possible outcomes, our denominator will be 8.
2. Find the numerator. To do this we need to find out of all the 8 possible outcomes, how many are them are y. Since its only 1 y, the numerator will be 1.
3. Now all we have to do now is make our fraction. The 8 possible outcomes given, only one of them has y which means that our fraction will be 1/8.
4. Answer: 1/8 or .125 or 12.5% chance for the spinner to land on y. I hope this helps!
Answer:
9 two year olds, 18 three year olds, 18 four year olds
Step-by-step explanation:
Let's say x is the number of 2 year olds. There are double the number of three year olds (2x) . Four year olds is the same as 3 year olds (2x).
x + 2x +2x = 45
5x=45
x= 9
Double is 18 for 3 and four year olds.
Answer:
Area of a trapezoid flat land = 1400mi ^2
Step-by-step explanation:
Area of a trapezoid is easy to remember
= shaped front face = house with sloped sides flat roof.
bases actually are the parellel lines, which we add.
290 mi + 410 = 700 (non slope)
Then we multiply the height of the slope = 20 x 700 (with the non slope squarer shape) 20 x 700 = 1400mi ^2
