Answer:
$360.
Step-by-step explanation: 6 ten dollar bills would be 60, and 3 one hundred dollar bills would be 300. Add it together, and you will get 360.
Use the Law of Sines for this one: 26/sin 55 = 28/sin A; 26 sin A = 28 sin 55;
sin A = 28 sin 55/26; sin A = 22.9362/26; sin A = .88216, and inverse sin(.88216) = 61.90
Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
3/4t+1/8=3/4(t+8)
3/4t+1/8=3/4t +6
This makes it 1/8=6 which doesn't really make sense.

Step-by-step explanation:
This is not an example for using a quadratic formula.
![\dfrac{49}{2}-\dfrac{1}{4}x^2=0\qquad\text{subtract}\ \dfrac{49}{2}\ \text{from both sides}\\\\-\dfrac{1}{4}x^2=-\dfrac{49}{2}\qquad\text{multiply both sides by (-4)}\\\\x^2=(2)(49)\to x=\pm\sqrt{(2)(49)}\\\\x=\pm\sqrt2\cdot\sqrt{49}\\\\x=-7\sqrt2\ \vee\ x=7\sqrt2](https://tex.z-dn.net/?f=%5Cdfrac%7B49%7D%7B2%7D-%5Cdfrac%7B1%7D%7B4%7Dx%5E2%3D0%5Cqquad%5Ctext%7Bsubtract%7D%5C%20%5Cdfrac%7B49%7D%7B2%7D%5C%20%5Ctext%7Bfrom%20both%20sides%7D%5C%5C%5C%5C-%5Cdfrac%7B1%7D%7B4%7Dx%5E2%3D-%5Cdfrac%7B49%7D%7B2%7D%5Cqquad%5Ctext%7Bmultiply%20both%20sides%20by%20%28-4%29%7D%5C%5C%5C%5Cx%5E2%3D%282%29%2849%29%5Cto%20x%3D%5Cpm%5Csqrt%7B%282%29%2849%29%7D%5C%5C%5C%5Cx%3D%5Cpm%5Csqrt2%5Ccdot%5Csqrt%7B49%7D%5C%5C%5C%5Cx%3D-7%5Csqrt2%5C%20%5Cvee%5C%20x%3D7%5Csqrt2)
