Answer:
(5,4)
Step-by-step explanation:
-x+2y=3
3x-2y=7
Add the like terms( 2y and -2y)(-x and 3x)(3 and 7) together. Do this vertically. 2y and -2y cancel eachother out.
Divide both sides by 2
To find y, substitute x in for y in one of the equations
add 5 to both sides
Divide both sides by 2
Check:
Answer: 54 berry plants
Step-by-step explanation:
From the sample there are:
Lettuce = 12
Tomatoes = 6
Peppers = 3
Berries = 9
The total is: = 12 + 6 + 3 + 9 = 30 plants
Berries comprise of:
= 9/30
= 3/10 of the plants
If they want to plant a total of 180, the number of berrie plants needed is:
= 3/10 * 180
= 54 berry plants
Are these true and false? I think it's true for both
11 drinks because 85x11 = £9.35
Answer:
x= "a certain number of inches"
side a= x-3
side b= 2 inches
multiply:
Area= a(b)
A= (x-3)2
A= 2(x-3)
distribute:
A= 2(x-3)
A= (2*x) + (2*-3)
A= 2x-6
Area= 2(x-3)
Area= 2x-6
Step-by-step explanation:
The area of the rectangle is equal to the multiple of its two sides this is equal to two inches times an expression three less than a certain number "x". Using the distributive property, we can solve this expression further to find that the area of this rectangle is also equal to six less than doubling a certain number x.
