The answer would be E because as you may know, 10 mm is equal to 1 cm. So, 230 mm³ is equal to 23 cm³.
Answer:
x=4
Step-by-step explanation:
1 Add 11 to both sides.
2x=7+12x=7+1
2 Simplify 7+17+1 to 88.
2x=82x=8
3 Divide both sides by 22.
x=\frac{8}{2}x=
2
8
4 Simplify \frac{8}{2}
2
8
to 44.
x=4x=4
cheek:
1 Let x=4x=4.
2\times 4-1=72×4−1=7
2 Simplify 2\times 42×4 to 88.
8-1=78−1=7
3 Simplify 8-18−1 to 77.
7=7 7=7
(or -3)
15.5 times 5.26 is 81.53 and 80 is closest to that so D
