Answer:

b = 10

-2d = -38

x = -1.2

Step-by-step explanation:

b = 10 and x = -1.2 only have one variable. You can divide -2 to both sides for -2d = -38 getting d = 19.

0.1 = 0.1 have no variable meaning that any number can be correct in the equation

1/3 ≠ 1/3 has a cross in the equal sign meaning that there is no correct answer for the equation.

Answer:

The 6% simple interest account earns more interest in 2 years.

Step-by-step explanation:

You can compare the multipliers in the interest formulas.

For simple interest, the amount in the account (A) starting with principal P and earning at rate r for t years will be ...

A = P(1 +rt)

For the values given, r=.06 and t=2, the multiplier is ...

1 +rt = 1 +.06·2 = 1.12

For interest compounded annually, the amount will be ...

A = P(1 +r)^t

For the given values, the multiplier is ...

(1+r)^t = (1.04)^2 = 1.0816

Since 1.12 > 1.0816, the account earning simple interest will earn more interest.

Andrew is showing his work in simplifying −4.5 + 4.2 + 5.6 − 7.3. Identify any errors in his work or in his reasoning. Write fee

Vinil7 [7]

Solving the expression $-4.5 + 4.2 + 5.6 -7.3$ we get -2.

Comparing the solution with the one given, you can find the errors.

Step-by-step explanation:

We need to simplify $-4.5 + 4.2 + 5.6 -7.3$ and identify errors.

Since the steps are not shown, so we cannot identify errors but I can solve the expression and you can compare to find errors.

Simplifying:

$-4.5 + 4.2 + 5.6 -7.3$

Using algebraic rule: if one digit has positive (+) sign and other digit has negative (-) sign then we will perform subtraction. and after subtraction, the sign of bigger value will be the sign of result.

Using the rule and solving:

$=(-4.5 + 4.2) + 5.6 -7.3$

$=-0.3 + 5.6 -7.3$

$=(-0.3 + 5.6) -7.3$

$=5.3 -7.3$

$=-2$

Solving the expression $-4.5 + 4.2 + 5.6 -7.3$ we get -2

Comparing the solution with the one given, you can find the errors.
