Answer:

True

Step-by-step explanation:

To solve, substitute known values:

- 3  \stackrel{?}{ = }5(2) - 13

Then simplify:

- 3  \stackrel{?}{ = }10 - 13 \\  - 3 =  - 3

The average yearly salary of a lawyer is ​$26 thousand less than twice that of an architect.​ Combined, an architect and a lawye
Paha777 [63]

The architect earns $47000 yearly and the lawyer earns $68,000 yearly.

<h3>How to solve algebra problems?</h3>

Let x = salary of architect, in thousands

Let 2x - 26 be the salary of lawyer, in thousands

Thus, if their salary combined is $214 thousand, then we have the algebra expression;

2x + 2x - 26 = 214

4x - 26 = 214

4x = 214 - 26

4x = 188

x = 47, in thousands.

The architect earns $47000 yearly

The lawyer earns 2(47000) - 26000 = $68,000 yearly

MariettaO [177]

Answer:

<u><em>Steven is 15 and one half years old now</em></u>

Step-by-step explanation:

<u />

Linear equations

Sometimes we need to know the value of a variable in a given equation and that variable is given as a polynomial of degree 1. Solving for that variable means isolating it and replacing the other known values

Steven was 7 years old eight and one-half years ago. If we call x as the actual age of Steven, his age eight and one-half years ago was

x-8\frac{1}{2}

We know he was 7 years old then, so

x-8\frac{1}{2}=7

We need to know his actual age, so let's solve for x, adding 8\frac{1}{2} to each side of the equation

x-8\frac{1}{2}+8\frac{1}{2}=7+8\frac{1}{2}

Simplifying

x=15\frac{1}{2}

Steven is 15 and one half years old now

Can someone please help me with this question
Elina [12.6K]

Answer:

The answer should be: B

I think it's B because there are 2 cups of water (2c) and 7 bottles of water (7w) which costs $16 so that would be 2c +7w=16. Also for the other one, it's 3 cups (3c) and 8 bottles of water (8W) and the cost is $19 so that would be

3c + 8w =19

Step-by-step explanation: Hope this helps and gl :))
