Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2
Answer:
0.8 would be the approximate height
Step-by-step explanation:
you can make an equation and solve for the height (x)
375 = 3.14(12.5^2)x
when you solve this equation, you specifically get 0.76. but your question is asking for the approximate, so you would round it up to 0.8. hope this helps!
Answer:
around 8
Step-by-step explanation:
(34*17)/72 = 8.03
The area is the same, regardless of how you find it. It is the product of base length and height measured perpendicular to that base.
.. 15*8 = 10*AX
.. AX = 15*8/10 = 12
The answer is 200:9 because the signs are not equal, you have convert one of them into one sign.
40cm=400cm
400mm:18mm
200mm:9mm
answer-200mm:9mm
