Answer:

x = 34

Step-by-step explanation:

4x and 44 are adjacent angles on a straight line and sum to 180° , that is

4x + 44 = 180 ( subtract 44 from both sides )

4x = 136 ( divide both sides by 4 )

x = 34

Solve: 3x - 2x + 4 = 5x - 4x - 8 <br> A)3 <br> B)6 <br> C)-3 <br> D)no solution

tensa zangetsu [6.8K]

3x - 2x + 4 = 5x - 4x - 8

First, let's focus on the left side of the problem (3x - 2x + 4). Let's subtract 3x - 2x which will get us 1, and since a variable by itself is considered 1, we can just put the variable.
$1 + 4 = 5x - 4x - 8$

Second, now let's focus on the right side of the problem (5x - 4x - 8). Subtract 5x - 4x to once again get 1. Replace it with the variable and leave the rest.
$x = 4 = x - 8$

Third, we can now cancel out x on each side. This will leave us with 4 = -8, which is false, meaning that there is no solution to this problem.

Answer:

0.6x = 87

Step-by-step explanation:

Hi, to answer this question we have to write en equation:

We have to multiply the variable x by the percentage given (60%) in decimal form (divided by 100). That expression must be equal to 87.

Mathematically speaking:

x (60/100) = 87

0.6x = 87

A candy manufacturer has 130 pounds of chocolate-covered cherries and 170 pounds of chocolate-covered mints in stock. He decides

Ilia_Sergeevich [38]

Answer:

He should prepare 260 pounds of first mixture and 0 pounds of second mixture

Step-by-step explanation:

Let x be the total quantity ( in pounds ) of cherries and mints in the first mixture and y be the total quantity in second mixture,

Since, first mixture will contain half cherries and half mints by weight,

That is, in first mixture,

Cherries = $\frac{x}{2}$

Mints = $\frac{x}{2}$ ,

While, second mixture will contain one-third cherries and two-thirds mints by weight,

That is, in second mixture,

Cherries = $\frac{y}{3}$

Mints = $\frac{2y}{3}$

According to the question,

The manufacturer has 130 pounds of chocolate-covered cherries and 170 pounds of chocolate-covered mints in stock,

That is,

$\frac{x}{2}+\frac{y}{3} \leq 130$

$\frac{x}{2}+\frac{2y}{3}\leq 170$

Also, pounds can not be negative,

x ≥ 0, y ≥ 0,

Since, the first and second mixture must be sell at the rate of $2.00 per pound and $1.25 per pound respectively,

Hence, the total revenue,

Z = 2.00x + 1.25y

Which is the function that have to maximise,

By plotting the above inequalities,

Vertex of feasible regions are,

(0,255), (180, 120) and (260, 0),

Also, at (260, 0), Z is maximum,

Hence, he should prepare 260 pounds of first mixture and 0 pounds of second mixture in order to maximize his sales revenue.

Explain how an estimate helps you place the decimal point when multiplying 3.9 × 5.3

natali 33 [55]

An estimate helps you because you round 3.9 to 4 and 5.3 to 5 so then you can give a rough estimation
