Step-by-step explanation:
64 times 4 =44
44 divided by 2= 22
Answer: A, D, and E
Step-by-step explanation:
Basically, you want to divide each of these answers by 5. Which ever one gives you a solid number (meaning no decimals) then that would be one option.
Hope this helps!
Answer:
D About 2000 times
Step-by-step explanation:
About 2000 times
Saturn = 5.683 × 10^32
Mercury = 3.302 × 10^29
Unit of measurement is irrelevant in ratios.
Answer:
12 ¼
Step-by-step explanation:
if you add the 16ths its up to 4 16ths, simplified that is ¼. then you add the 3s, 3 × 4 is 12. add the two, 12 ¼
1) Data:
Meal calories consumed
Breakfast 400 cal
Lunch 350 cal
Dinner x
------------------
Total 400 + 350 + x = 750 + x
2) Equation: <span>
She consumes 2/3 of her daily calories at dinner => (2/3)[750+x] = x
3) Analyze each statement:
</span><span>a) Lena
consumed 1500 cal at dinner.
Solve the equation to find if the statement is true:
</span>
<span><span>(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
d) Lena
consumed 1000 cal at dinner.
No, we calculated that she consumed 500 cal at dinner.
Conclusion: FALSE statement
e) The equation 2/3(x)=x(400+350) can be used
to model the situation.
No: (2/3) x = 500 and x(400+350) = 500*750 = 375,00, which are not equal.
Conclusion: FALSE 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.
</span>Conclusion: TRUE statement
