Answer:
sorry this doesnt make sense but i think your mutiplying so it would be 30 because he took 10 minutes on his homework and 3 minutes per question
Step-by-step explanation:
For the top left box you T to get to W is 3 so for R it would bevy because that would be ahead 3 for E you would go back 3 so it would be B. A is D. The rule is probably add 3. The top right is basically the opposite so Hot-cold, left-right, first-LAST, soft-hard, and top-BOTTOM. The rule is probably the opposite . The bottom one is adding 3 just like the top left. Hope you understand this I know it's a lot of writing.
Answer:
Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation
x + 2x + 2x + 30 = 380
collect like terms
5x = 350
x = 70
the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm
Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct
