larry and tom were standing next to each other in the backyard when tom challenged larry to guess how tall he is. larry
knew his own height is 6.5 feet, and when they measured their shadows, larry's shadow was 8 feet long and tom's was
7.75 feet long. what is tom's height? round to the nearest tenth.

6.3ft

Step-by-step explanation:

Larry is 6.5 feet tall and leaves a shadow that is 8 feet long which identifies the ratio between height and shadow as 6.5/8. This would give you .8125 which let's you know your height will be .8125 times what your shadow's height is. After, you multiply 7.75(.8125). The answer is 6.296875 but since you need to round to the nearest tenth, your answer would be 6.3ft.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
