3t - 15 = 2t + 10
t = 25
<Y = 2(25) + 10 = 60
<X = 4r
so
4r + 60 = 180
4r = 120 (<X = 4r)
answer
<X = 120
Answer:
153.86in^2
Step-by-step explanation:
Area of a circle = πr²
Where : = π = pi = 3.14
R = radius = 14/2 = 7
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
7² x 3.14 = 153.86
A radius is half of the diameter
If you let j, c, t represent the prices of jeans, camisoles, and t-shirts, respectively, the three purchases can be described by ...
2j +2c +4t = 90.00
1j +0c +3t = 42.50
1j +3c +2t = 62.00
It is convenient to let a calculator solve these equations. It can tell you the row-reduced matrix equations are ...
[[1 0 0 24.5]
[0 1 0 8.5 ]
[0 0 1 6 ]]
which means
flare jeans cost $24.50
camisoles cost $8.50
T-shirts cost $6.00
Alright! So the easiest way for me personally is to make the fraction over a number like 10 or a 100. So... for 5/20, I would multiply both numbers by 5. That gives you 25/100.
Then you could just divide.
Hope that makes sense! Let me know if you any more help!!
