For #1: If we plug in g=2, we get -5(2)-6=-16
For #2: That would be c+3 since we are adding both
For #3: Add 2 to both sides to get x=18
For #4: Multiply both sides by -12 to get Z=60
For #5: 8.1 rounds to 8, and 5.3 rounds to 5. Then you add 8 to both sides and you get around 13
For #6: Add 44 to both sides to get T=58
For #7: Subtract 50 on both sides to get j=-80
For #8: None of the answer choices are right
For #9: Multiply 2.2 on both sides to get Z=12.76
Hope these explanations help.
trurnip 2020 is wrong
hey answers thank you i got 88.88% because i missclicked but yours are all right :/ :/ :/ :/ :/ :/ :/
hahahahah im gy with an a
Thank you so much AJ L! I was struggling.
You better be right Trump 2020, my grade depends on it
To solve these problems, we will substitute the given values into the equations and simplify.
1. -5g - 6 for g = 2
-5(2) - 6 = -10 - 6 = -16
The answer is -16.
2. The algebraic expression for the sum of 3 coins and c coins is "3 + c".
The answer is A. C+3.
3. To find the value of x in the equation x - 2 = 16, we need to isolate x.
Adding 2 to both sides of the equation gives us x = 18.
The answer is B. 18.
4. To solve the equation Z / -12 = -5, we need to multiply both sides by -12 to isolate Z.
Z = -5 * -12 = 60
The answer is D. 60.
5. To estimate the solution of the equation x - 8.1 = 5.3 to the nearest whole number, we can add 8.1 to 5.3.
x = 13.4
The answer is A. About 13.
6. To solve the equation 14 = T - 44, we need to isolate T. Adding 44 to both sides gives us T = 58.
The answer is D. 58.
7. To solve the equation -30 = j + 50, we need to isolate j. Subtracting 50 from both sides gives us j = -80.
The answer is D. -80.
8. To solve the equation 2.8x = 9.24, we need to isolate x. Dividing both sides by 2.8 gives us x = 9.24 / 2.8 ≈ 3.3
The answer is C. -3.3.
9. To solve the equation 5.8 = Z / 2.2, we need to multiply both sides by 2.2 to isolate Z.
Z = 5.8 * 2.2 ≈ 12.76
The answer is D. 12.76.
