isabella spends $4.87 on paintbrushes and paint. How many of each item does she buy? The paintbrushes cost $0.95 and the jar of paint cost $.099 each.

Answers

Answer 1

Answer: Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87. Answer: Isabella buys 2 paintbrushes and 3 jars of paint.

Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party. He put all the addresses in a bag and drew a random sample of 30 addresses. He then asked those families if they would help organize the fund-raising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference? No, this is not a valid inference because he asked only 30 families No, this is not a valid inference because he did not take a random sample of the neighborhood Yes, this is a valid inference because he took a random sample of the neighborhood Yes, this is a valid inference because the 30 families speak for the whole neighborhood

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let, consider the equation of y = mx+c,

where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.

standard form of linear equation is :

y = mx+c

comparing it with given equation :

y= -2x-9.

m = -2, c = -9

Therefore, y= -2x-9 is in standard form itself with slope m = -2 and y intercept c as -9.

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

2x + y = -9.

A candy company packages caramel into containers that hold 32 fluid ounces. In the last batch, 1,848 fluid ounces of caramel were made. How many containers were needed for this batch?

Answers

58 containers

Further explanation

Given:

A candy company packages caramel into containers that hold 32 fluid ounces.
In the last batch, 1,848 fluid ounces of caramel were made.

Question:

How many containers were needed for this batch?

The Process:

Let us reorder information that is known and asked:

$\boxed{ \ 1 \ container = 32 \ fl. \ oz. \ }$
$\boxed{ \ ? \ container = 1,848 \ fl. \ oz. \ }$

To get how many containers were needed for this batch, we have to do the division process. The total fluid ounce of caramel was made divided by the amount of fluid ounce in each container.

Let us count the number of containers needed for this batch.

$\boxed{ \ 1,848 \ fl. \ oz. * (1 \ container)/(32 \ fl. \ oz.) \ ? \ }}$

$\boxed{ \ = (1,848)/(32) \ }$

Simplify it. The numerator and denominator are equally divided by 8.

$\boxed{ \ = (231)/(4) \ }$

We can use the following strategy:

$\boxed{ \ = (228)/(4) + (3)/(4) \ }$

$\boxed{ \ = 57 + (3)/(4) \ }$

$\boxed{\boxed{ \ = 57(3)/(4) \ }}$

In a decimal,

$\boxed{ \ = 57 + (3 * 25)/(4 * 25) \ }$

$\boxed{ \ = 57 + (75)/(100) \ }$

$\boxed{\boxed{ \ 57.75 \ }}$

Conclusion

The result is $\boxed{57 (3)/(4) \ or \ 57.75}$ containers, not integers.
This means we need 57 containers and one more container that contains $(3)/(4)$ parts.
Thus, the number of containers needed for this batch is 58 containers, after rounding up.

What’s the value of x?

Answers

Answer:

Step-by-step explanation:

Since l and m are parallel lines, then

5x - 16 = 2x + 50 ( corresponding angles )

Subtract 2x from both sides

3x - 16 = 50 ( add 16 to both sides )

3x = 66 ( divide both sides by 3 )

x = 22 → E
