The answer is 5 39/100
5.39 as a fraction is 539/100
To make that a mixed number you need to find out how many times the denominator goes into the numerator (100 goes into 539 5 times) so your whole number is 5 and you're left with 39/100 as the fraction, which can't be simplified any more.
X will equal -2
-10+ 8x= -26
8x= -16
x=-2
3x=45
(divide each side by 3)
x=15
You need to answer 15 correctly.
Answer:
Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P= 11+11+19.3+19.3 or P=11(2)+19.3(2) =60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A= 11(19.3)cm =212.3
Hey there! :D
y=2x-9
We can plug that in as y, since y is equal to 2x-9.
5x-3(2x-9)= 23
Distribute.
5x-6x+27= 23
-1x+27=23
Subtract 27 on both sides.
-1x=-4
Divide both sides by -1.
x=4
Now, plug that in for y.
y=2(4)-9
y=8-9
y=-1
(4,-1) <== solution
I hope this helps!
