Nancy bought 354 short sleeve shirts and 177 long sleeve shirts.
Step-by-step explanation:
Given,
x represents the number of long sleeve shirts
y represents the number of short sleeve shirts
According to given statement;
x+y=531 Eqn 1
x = 2y Eqn 2
Putting value of x from Eqn 2 in Eqn 1
![2y+y=531\\3y=531](https://tex.z-dn.net/?f=2y%2By%3D531%5C%5C3y%3D531)
Dividing both sides by 3
![\frac{3y}{3}=\frac{531}{3}\\y=177](https://tex.z-dn.net/?f=%5Cfrac%7B3y%7D%7B3%7D%3D%5Cfrac%7B531%7D%7B3%7D%5C%5Cy%3D177)
Putting y=177 in Eqn 2
![x=2(177)\\x=354](https://tex.z-dn.net/?f=x%3D2%28177%29%5C%5Cx%3D354)

on the number line 0.25 is before 0.4
Answer:
AB = 11.5mm
Step-by-step explanation:
let the hypotenuse be AC = 23mm
Angle of elevation = 30degrees
Required
Opposite AB
Using the SOH CAH TOA identity
Sin theta = opp/hyp
Sin 30 = AB/AC
Sin 30 = AB/23
0.5 = AB/23
AB = 0.5 * 23
AB = 11.5mm
<span>(3 + x^3 + 3x^2)+(2x^3 −2 −4x^2)
</span>= <span>3 + x^3 + 3x^2+ 2x^3 −2 −4x^2
= 3x^3 - x^2 + 1
answer

Answer:
Correct solution:
45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64
Step-by-step explanation:
they rode 45.7, 40.9, and 38 miles
= (45.7 + 40.9 + 38) miles
= 124.6 miles
Convert 124 .6 miles to kilometers
1 kilometer = 0.621 miles
124.60 miles = 124.60 / 0.621
= 200.64 kilometers
This is the correct solution because he divided 124.60 miles by 0.621
45.7 + 40.9 + 38.0 = 124.6 miles. 124.6 divided by 0.621 = 200.64
