Increase £64 by 70%??????

Answers

Answer 1
Answer: I'm not sure if you used the euro sign accidentally or what but this is how to increase 64 by 70%

divide 64 by 10.
6.40
then multiply it by 7.
44.80
then add 44.8 to your original number. (64)
the answer is:
108.8

If you did put that sign there purposely and if it means something then I don't know if it matters or if this is right.

Three of the angles of a quadrilateral are 120 48 and 92 what is the size of the 4th angle

Answers

Answer:

Measure of fourth angle of quadrilateral is:

100

Step-by-step explanation:

We know that the sum of angles in a quadrilateral is 360°

Three of the angles of a quadrilateral are 120 48 and 92

we have to find the sum of the fourth angle of the quadrilateral

Let measure of fourth angle be x

120+48+92+x= 360

i.e. 260+x = 360

Subtracting both sides by 260, we get

x= 100

Hence, Measure of fourth angle of quadrilateral is:

100
You do 120+48+92=280All angles in a quadrilateral add up to 360, so 360-280=80The answer is 80HAVE FUN DOING MATHS!

Let f(x) = 9x − 2 and g(x) = −x + 3. Find f(g(x)).

Answers

f(x) = 9x - 2
g(x) = -x + 3

f(g(x)) = 9(-x + 3) - 2
f(g(x)) = 9(-x) + 9(3) - 2
f(g(x)) = -9x + 27 - 2
f(g(x)) = -9x + 25
f(g(x))=9(-x+3)-2
So: f(g(x)=-9x+27-2=-9x+25
