Answer: x= 19
Step-by-step explanation:
RS =~ ST presumably reads segment RS is congruent to segment ST, i.e. the same length.
Then the triangle is isosceles, and angle SRT = angle STR. Angle STU = 180-angle STR.
SRT = 3x - 48, STU = 9x, so STR = 180-9x
SRT = STR
3x - 48 = 180 - 9x
3x + 9x = 180 + 48
12x = 228
x = 19
Answer:
x-5=3x+1 (x=-3)
Step-by-step explanation:
5 less (_-5)
than a number (x)
is equivalent to (=)
1 more than (+1)
than three times the number (3x)
combine them all to get x-5=3x+1
extra:
add 5 to each side x=3x+6
subtract x from each side 0=2x+6
subtract 6 from each side -6=2x
divide each side by 2 -3=x

- 1apple pie needs 2/3/4pounds of apple
- 1pound cost $2.49
- 2/3/4 = ?
- 2/3/4 ×2.49
- =$6.85 for one pie
- For 3 pies ,
- =$6.85×3
- = $20.55
There will not be any pieces left over. 23 divides into 345 evenly, to get 15 pieces per person. Hope that helps!
Would it be 6.5 since the scale factor is 1.5 and its added to the 3 to get 4.5? correct me if i’m wrong
