Leena consumes 400 cal at breakfast and 350 cal at lunch. She consumes 2/3 of her daily calories at dinner. If X represents the calories consumed at dinner, which statements describe the situation? Check all that apply. Lena consumed 1500 cal at dinner. Do you equation 2/3 (x+400+350)=x can be used to model the situation. Lena consumed 500 cal at dinner. Lena consumed 1000 cal at dinner. The equation 2/3(x)=x(400+350) can be used to model the situation. The equation 2/3x(400+350)=x Can’t be used to model the situation

Answer:
The answer above is confusing and incorrect, the correct answer is A and B. The answers are contradicting, though it is somewhat explained.
Step-by-step explanation:
1) Data:a) Lena
consumed 1500 cal at dinner. Solve the equation to find if the statement is true: (2/3)[750+x] = x </span>2(750+x) = 3x 1500 + 2x = 3x 1500 = 3x - 2x x = 1500 Conclusión: TRUE stament. b) Do you equation 2/3 (x+400+350)=x can be
used to model the situation. That is the same equation that I found above. Conclusion: TRUE statement c) Lena consumed 500 cal at dinner. She consumed (2/3) * 1500 = 500 cal Conclusion: TRUE statement FALSE statementFALSE statement. f) The equation 2/3x(400+350)=x Can’t be used to
model the situation
No: in that equation the variable x cancels out because it appears a factor at both sides. Conclusion: TRUE statement

Step-by-step explanation:
a. ( p × q ) ( q + r )
= ( -24 × 12 ) ( 12 + -6 )
= 288 × 18
= 5184
b. ( p × r ) ( r - q )
= ( -24 × -6 ) ( -6 - 12 )
= ( 144 ) ( -18 )
= -2592
Answer:
√308 or 17.5
Step-by-step explanation:
c^2=a^2+b^2
c^2-a^2=b^2
Substitute
18^2-4^2=b^2
324-16=b^2
b^2=308
b=√308 or b=17.5
