A factor is one part of a product.
In the given expression first we separate the terms.
here we have two terms: 15 and 20x
factors of first term 15 : since just one number is there so factors of 15 would be 1, 3, 5 and 15
factors of second term 20x: product of 20 and x gives 20x, so factors of 20x are 1,2,4,5, 10,20 and x
Answer:
Step-by-step explanation:
Equation
-5(-3x+1)=-45 If this is not correct, leave a comment please.
Solution
-5(-3x+1)=-45 Divide by -5
-5(-3x + 1)/5 = -45/-5
(-3x + 1) = 9 Remove the brackets
-3x + 1 = 9 Subtract 1 from both sides
-3x + 1 - 1 = 9 - 1 Simplify
-3x = 8 Divide by -3
-3x/-3 = 8/-3
x = -8/3
or
x = -2.66
or
x = - 2 2/3
Answer:
x = 44/19, y = 33/20
Step-by-step explanation:
Multiply the first eq by 18, to get:
90/y - 36/x = 39
so 36/x = 90/y - 39
in this form we can plug it into the second eq:
90/y - 39 - 24/y = 1 =>
66/y = 40 =>
y = 66/40 = 33/20
Fill that in the first:
100/33 - 2/x = 13/6 =>
200/66 - 143/66 = 2/x =>
57/66 = 2/x =>
57x = 2*66
x = 132/57 = 44/19
Answer:
no it is not
Step-by-step explanation:
Let's use the Pythagorean theorem for this
a^2+b^2=c^2
60^2+63^2=88^2
3600+3969=7744
7569≠7744
This means that this triangle isn't a right triangle
