Answer:
a = 261; b = 253
Step-by-step explanation:
label candy bar A as a
label candy bar B as b
<u>Make 2 equations.</u>
2b + a = 767 (1)
b + 2a = 775 (2)
<u>Solve for a in (1)</u>
2b + a = 767 (-2b)
a = -2b + 767
<u>Substitute for into (2)</u>
b + 2( -2b + 767 ) = 775 (flip)
2( -2b + 767 ) + b = 775 (solve)
−4b + 1534 + b = 775 (add b)
-3b + 1534 = 775 (subtract 1534 from both sides)
−3b = −759 (divide both sides by 3)
b = 253
<u>Substitute b into (1)</u>
a = -2b + 767 (substitute)
a = -2 (253) + 767 (solve)
a = -506 + 767 (add)
a = 261
Answer:
4.25
Step-by-step explanation:
Answer: -5
Step-by-step explanation: 2 + -11 = -9 and subtract -4 from it since it’s the sum of 2 + -6. -9 - -4 is -9 + 4 so -5
Answer:
6/12 or half
Step-by-step explanation:
this would be the answer because the lowest common denominator of 4 and 3 is 12 so you'd multiply them you'd get 12 then multiply 2 and 3 and get six therfore the answer is 6/12 or 1/2
