Answer:
you can simplify rations just like you simplify fractions. Whenever you are able to evenly divide both parts of the ratio with out changing the equation's answer, you are able to.
for example
if it were 3:6, you can simplify this by dividing these both by 3, leaving you with 1:2.
Answer:
Step-by-step explanation:
Question 1: C
1 multiplied by 5 = 5
1 plus 5 = 6
So you get: (x+5)(x+1) which means x = -5 or -1
Question 2: B
2 multiplied by -4 = - 8
2 plus -4 = -2
So you get: (x-4)(x+2) which means x = 4 or -2
Answer:
14.8 feet
Step-by-step explanation:
since this is creating a right triangle you can use the Pythagorean theorem which is a^2 + b^2 = c^2, and by plugging in the one leg length and the hypotenuse length you get 14.8324 which rounds up to 14.8
Answer:
<em>(2.5, 3.75), or using fractions, (5/2, 15/4)</em>
Step-by-step explanation:
3x - 2y = 0
x + 2y = 10
Add the equations and solve for x.
4x = 10
x = 2.5
Substitute x = 2.5 in the first equation, and solve for y.
3(2.5) - 2y = 0
-2y = -7.5
y = 3.75
