5x and the right angle+15 are vertical angles so they are equal.
5x=90+15
5x=105
x=21
The midpoint divides the line into two equal lengths so 8x+11 must be equal to 12x-1.
8x+11=12x-1
4x=12
x=3.
I cannot really solve this since you didn't provide a value for x...?
Something is missing from your question, please check again.
Since the line is dotted, it can only be y < __x - __ or y > __x - __.
The slope is -3/2x and the intercept -2. The shaded area is below the line so the second answer is correct.
Let x be the number of flowers with 3 petals and 30-x the number of flowers with 4 petals. We form an equation:
3x+4(30-x)=102
3x+120-4x=102
-x+120=102
-x=-18
x=18 3 petal flowers,
So there are 30-18=12 4 petal flowers.
I'm pretty sure this is fake as the real Richard wouldn't use "plz" and an emoji...he'd probably type more professionally.
This a math/STEM site, not grammar, but I'll try:
1. I think it's resume.
2. I think it's goal.
Grammar is not my strong suit so these may be wrong.
Let x be the number of t-shirts sold. Let 60-x be the number of hats sold. They have a total cost of 870. We form an equation:
18x+12(60-x)=870
18x+720-12x=870
6x+720=870
6x=150
x=25
25 t-shirts were sold and 60-25=35 hats.
Let x be David's age. Dan's age is x+5, and Bridget's x-8. We add these together to get 57 and solve for x.
x+(x+5)+(x-8)=57
3x-3=57
3x=60
x=20
Dan is the oldest out of them, and his age is 20+5=25.
