Answer: X=18
Step by Step:
2−10+x=6−8+12
Step 1: Simplify both sides of the equation.
2−10+x=6−8+12
2+−10+x=6+−8+12
(x)+(2+−10)=(6+−8+12)(Combine Like Terms)
x+−8=10
x−8=10
Step 2: Add 8 to both sides.
x−8+8=10+8
x=18
Answer:
Granted that uppercase letters are the angles measurements and lowercase letters are the side lengths. I also was unable to round as I don't know to what decimal you need to round to.
First to find the measure of angle B, we must subtract A and C from 180
![180-21-105=54](https://tex.z-dn.net/?f=180-21-105%3D54)
B=54
Next, we can use the law of sines in order to find the measures of a and b
As a reminder, The law of sines is
![\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7BsinA%7D%20%3D%5Cfrac%7Bb%7D%7BsinB%7D%20%3D%5Cfrac%7Bc%7D%7BsinC%7D)
First, lets solve for b
![\frac{b}{sin54}=\frac{5}{sin105} \\\\b=\frac{(5)sin54}{sin105}\\\\b=4.187780119](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bsin54%7D%3D%5Cfrac%7B5%7D%7Bsin105%7D%20%5C%5C%5C%5Cb%3D%5Cfrac%7B%285%29sin54%7D%7Bsin105%7D%5C%5C%5C%5Cb%3D4.187780119)
Next lets solve for a
![\frac{a}{sin21}=\frac{5}{sin105} \\\\a=\frac{(5)sin21}{sin105}\\\\a=1.85504901](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bsin21%7D%3D%5Cfrac%7B5%7D%7Bsin105%7D%20%5C%5C%5C%5Ca%3D%5Cfrac%7B%285%29sin21%7D%7Bsin105%7D%5C%5C%5C%5Ca%3D1.85504901)
Answer:
1 quarter pound = 0.25 of a pound.
Give that:
Total amount of ground beef = pound
From 3.5 pound of beef we have to make burgers using 0.25 pound of beef in one burger
We have to find how many burgers can be made:
We have to divide 3.5 pound by 0.25 pound
i.e,
⇒14 quarter pounds burger can be made.
Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef
Step-by-step explanation:
Answer:
$839.95
Step-by-step explanation:
Sales tax = 7 % × cost
Sales tax = 0.07 × 785
Sales tax = $54.95
=====
Cost = price + sales tax
Cost = 785 + 54.95
Cost = $839.95
The cost to purchase is $839.95.
