Answer:

9 cans of soup and the 4 frozen dinners were purchased

Step-by-step explanation:

Let x represent the number of cans of soup purchased.

Let y represent the number of frozen dinners purchased.

Lincoln purchased a total of 13 cans of soup and frozen dinners. This means that

x + y = 13

Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium. The 13 cans of soup and frozen dinners which he purchased collectively contain 4450 mg of sodium. This means that

250x + 550y = 4450 - - - - - - - - -1

Substituting x = 13 - y into equation 1, it becomes

250(13 - y) + 550y = 4450

3250 - 250y + 550y = 4450

- 250y + 550y = 4450 - 3250

300y = 1200

y = 1200/300

y = 4

Substituting y = 4 into x = 13 - y, it becomes

x = 13 - 4 = 9

Answer:

If it's 107% of 50 the answer would be 53.5

If it's 107% more than 50 it would be 103.5

Step-by-step explanation:

107% of 50 is 53.5

50 × 107% = 53.5

50 × 107% = 53.5

Answer:

Step-by-step explanation:

when 13 bought we find these inequalities

x + 12y < 7  no

2x + 11y < 7.5 no

3x + 10y < 8 no

4x + 9y < 8.5 no

5x + 8y >  9  yes

When 14 bought we find these inequalities

x + 13y < 7.5 no

2x + 12y < 8 no

3x + 11y < 8.5 no

4x + 10y > 9 yes  

We want to find and solve a system of inequalities to determine some possible solutions to Arianna's situation.

The possible solution is:

x = 2

y = 12

And the graph can be seen at the end.

Now let's see how to solve this.

First, we need to write the system of inequalities, the information given is:

Now we can define the variables:

Then we must have:

x + y ≥ 13   (this means that she buys at least 13 fruits)

x*$1 + y*$0.50 ≤ $9  (this means that she can't spend more than $9)

Now we just need to graph these two lines, we can rewrite them as:

y ≥ 13 - x

y ≤ $9.00/$0.50 - x*$1/$0.50 = 18 - x*2

Then we just need to graph the two lines, and shade the region above the first one, and the region below the second one, the graph can be seen below:

Any point inside the double shaded region in the first quadrant is a possible solution. (we restrict only to the first quadrant because we can not use negative values for x nor for y).

Then a possible solution that we could choose is:

x = 2

y = 12

This means that she buys 2 peaches and 12 mangos.

Answer:

5x³-13x²+24x+12

Step-by-step explanation:

Start by distributing (5x+2) into (x²-3x+6)

It is easiest to start with 5x.

When distributing 5x, your answer should be: 5x³-15x²+30x.

Then, distribute the 2 just as you did for 5x.

Your answer for that should be: 2x²-6x+12

After that, add the like- terms from both answers together.

5x³-15x²+30x+2x²-6x+12

The final answer is then: 5x³-13x²+24x+12

Answer:

B. 73°

Step-by-step explanation:

The triangle is an isosceles triangle as it has 2 equal sides. This implies that the angles opposite to the two equal sides are of the same measure.

Therefore,

x = (180 - 34) ÷ 2

x = 146 ÷ 2

x = 73°

Step-by-step explanation:

10n+10

Explanation:

When n=0 that must mean that you always add 10. From there it's pretty obvious that it's increasing by 10 each time, meaning that you multiply n by 10 as well

Answer:

The point after the reflection of (-4,-3) across the y-axis is:

Hence, option B is correct.

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-4, -3)

Let say the point is A(-4, -3)

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-4, -3) → A'(-(-4), -3) → A'(4, -3)

Therefore, the point after the reflection of (-4,-3) across the y-axis is:

Hence, option B is correct.
