Answer:
123+b=180 (being sum of straight angle)
b=180-123
b=57
Are these three different questions? if so:
1: add 19 to both sides to get a = 3 +19
answer: a = 22
2: multiply both sides by 7 to get y = 10 * 7
answer: y = 70
3: divide both sides by 5 to get g = 100/5
answer: g = 20
hope this helped! good luck :)
Answer:
Step-by-step explanation:
we have a 51 in sandwich
let a piece be x
we have x= shorter piece
another piece is x+6
another piece (x+6)-9=x-3
x+x+6+x-3=51
3x=51-3
3x=48
x=48/3=16
x=16, longer piece is 16+6=22, shorter piece =10
The slope of a line perpendicular to another is the negative reciprocal of the original. The negative reciprocal of -1 is 1. The equation will read:
y=x+b
To solve for the y-intercept (b), plug in the given values of x and y:
4=-2+b
<em>*Add 2 to both sides*</em>
D. 6
Hope this helps!!
To convert fractions into decimals simply divide the numerator (5) by the denominator (8). If you type in "5/8" into a calculator you will receive a compute of 0.625 which you can round to .6
