Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50

Answer:

$12.50

Step-by-step explanation:

We have to find value of his allowance

Let Ricardo received allowance =x

He spent his allowance on anew paperback book=\frac{x}{2}

He spent money on snacks=$1.25

He had money left=$5.00

According to question

\frac{x}{2}+1.25+5=x

6.25=x-\frac{x}{2}

6.25=\frac{2x-x}{2}

\frac{x}{2}=6.25

x=6.25\times 2

x=12.50

Hence, Ricardo received his allowance for the week =$12.50

What form of a linear equation is y - 6 = -4(x + 2) ?
Softa [21]

Answer:

Point slope form

Step-by-step explanation:

Given

y - 6 = -4(x + 2)

Required

Determine the form of linear equation

A linear has just three forms:

1. The slope intercept form.: This is always in form of y = mx + b

2. The point slope form: This is always in form of y - y_1 = m(x - cx_1(

2. The standard form: This is always in form of Ax + Bxx = c

<em>By comparison, the three forms with the question, we can see that option B answers the question.</em>
