Grade 7 Math Add And Subtracting Integers.

Jim's team loses one point each time they skip a turn, so since they skipped 6 turns, they would lose 6 points. They also earn one point each time they guess correctly, so since they guessed correctly 4 times, they would earn 4 points. Therefore, their total score would be -2 points (-6 + 4 = -2).

The student council's expected profit is -150. This means that they are projected to have a loss of $150. This can be calculated by subtracting the total expenses ($200 for tickets + $200 for music + $150 for snacks) from the total funds raised. Since the expenses exceed the funds raised, the student council will have a negative profit.

The elevation of the tunnel relative to the ground is -35 meters. This means that the tunnel is 35 meters below the ground level.

Jim's team skipped 6 turns, which means they lost 6 points. They also guessed correctly 4 times, earning them 4 points. Since each skipped turn results in a loss of 1 point and each correct guess earns them 1 point, the team's score can be calculated by subtracting the number of skipped turns from the number of correct guesses (-2 = 4 - 6). Therefore, Jim's team's score is -2.

Jim's team skipped 9 turns, which means they lost 9 points. They also guessed correctly 10 times, which means they earned 10 points. Therefore, their total score would be 10 - 9 = 1 point.

The position of the dolphin's friend relative to the surface of the water is 6.3 meters below the surface.

The given expression can be simplified by applying the rules of addition and subtraction. Starting from left to right, we have -11 + 2 which equals -9. Then, we have -(-5) which can be rewritten as +5, resulting in -9 + 5. Finally, adding 9 to -9 + 5 gives us a final answer of 5.

The elevation of the tunnel relative to the ground is -15 meters. This means that the tunnel is 15 meters below ground level.

The given expression is -1 + 2 - 8 - 9. When we evaluate this expression, we start from left to right, performing addition and subtraction operations. -1 + 2 equals 1, and then subtracting 8 gives us -7. Finally, subtracting 9 from -7 results in -16. Therefore, the correct answer is -16.

The given expression involves addition and subtraction of positive and negative numbers. When we simplify the expression, we first evaluate the negative sign inside the parentheses, which gives us -5+4+3+6. Then we perform the addition and subtraction from left to right, which gives us 8. Therefore, the correct answer is 8.

The student council's expected profit is -150. This means that they will have a loss of $150 from the school dance. The expenses for tickets, music, and snacks add up to $550, while the funds raised are only $200. Therefore, the council will have a deficit of $150.

The position of the dolphin's friend relative to the surface of the water is 5.3 meters below the surface.

Jim's bank account balance at the beginning of July was $13.00. He made a payment of $12.50 to the .99 store on July 5, which reduced his account balance to $0.50. Then, on July 8, he was charged a bank overdraft fee of $5.00, resulting in a negative account balance of -$4.50. However, on July 10, he made a bank deposit of $10.00, which brought his account balance back to $5.50. Therefore, Jim's current bank account balance is $5.50.

The student council's expected profit can be calculated by subtracting the total expenses from the total funds raised. In this case, the total expenses are $450 + $200 + $150 = $800. The total funds raised are $450 + $200 + $150 = $800. Therefore, the expected profit is $800 - $800 = $0.
