Let's first find how many students bring their lunch to school. This is 30% of 300. To find this value, convert the percentage to a fraction (or decimal) and multiply:
Since 90 students bring their lunch to school, we can say 210 students do not bring their lunch to school. (300 - 90 = 210)
Solution
3(-x+(2x+1))=x-1
3(x+1)=x-1
3x+3=x-1 collect like terms
3x-x=-1-3
2x=-4 divide both side by 2
x=-4/2=-2
Answer:
160 square feet
Step-by-step explanation:
For this problem you are required to find the unit rate.
420 square feet / 2 ⅝ or 2.625 pounds =
160 square feet = one pound of wild flower seeds
<em>I hope this was helpful; I was unaware if the problem was multiple choice or not. </em>
1, 4, 9, 16, 25, 36, 49…
And now find the difference between consecutive squares:
1 to 4 = 3
4 to 9 = 5
9 to 16 = 7
16 to 25 = 9
25 to 36 = 11
…
Hope this helps! :D
Answer:
146°; 34°
Step-by-step explanation:
Supplementary angles are two angles whose measures sum up to equal 180°. The supplement of one angle = 180° - its measure.
Given that an angle measures 112° more than its supplementary angle,
let x = the angle (larger angle)
Supplement of x = (180 - x) (smaller angle)
x = (180 - x) + 112
Solve for x
x = 180 - x + 112
x + x = 180 - x + 112 + x
2x = 180 + 112
2x = 292
2x/2 = 292/2
x = 146
The angle is 146°
Its supplement is 180 - 146 = 34°
