The expression that is equivalent to 0.40a is \frac 25a

<h3>What are equivalent expressions?</h3>

Equivalent expressions are expressions that have equal values, when evaluated or simplified

The expression is given as:

0.40a

Rewrite the above expression as a fraction

\frac 4{10}a

Simplify the fraction

\frac 25a

Hence, an equivalent expression of 0.4a is \frac 25a

Substitue the expression 5-3x into the second equation
Rina8888 [55]

Answer:

<h2><u>X= 1</u></h2>

Step-by-step explanation:

<em>y = 5 - 3x</em>

<em>5x - 4y = -3</em>

you substitute for y since you know what y equals.

so, it will then be

5x -4(5 -3x) = -3

you then multiply -4 by everything in the parenthesis

so then it will be

5x - 20 + 12x = -3

Then combine like terms

5x + 12x = 17x

then the new equation is

17x -20 = -3

the next step is to and 20 to both sides since it is negative you do the opposite.

17x - 20 = -3

<u>      + 20     +20</u>

17x = 17 divide 17 by both sides sice 17 is being multiplied by x you do the opposite and divide and you get 1.

<h2><u>so, X = 1</u></h2>

The graph below shows the cost C for bowling g games at Strike King. Another bowling center, Thunder Alley, charges $2.25 per ga
Lunna [17]

Answer:

They intersect when the Strike king is at (9,15.75) and Thunder Alley is at (7, 15.75). But only the X axes intersect. The X and Y axes intersect at (0,0) that's where they start and that is where they meet. Its a proportional relationship because their ratios are equivalent. It represents the constant of proportionality.
