Infinitely many solutions

Step-by-step explanation:

-5.9x - 3.7y = -2.1

5.9x + 3.7y = 2.1

If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.

This leaves us with:

0 = 0

Since this is true, that means there are infinite solutions.

Answer:

[tex] b \geqslant 14[/tex]

Step-by-step explanation:

Product of b and 2 = 2b

According to the given description:

[tex]2b \geqslant 28 \\ \\ b \geqslant \frac{28}{2} \\ \\ b \geqslant 14[/tex]

Answer:

A.) k=0.5

Step-by-step explanation:

If we use the formula given: y=kx, we can plug in values.

0.5=k(1)

0.5=(0.5)(1)

0.5=0.5

We know that to get from 1 to 0.5, we need to divide by two, or multiple by 1/2. 1/2 in decimal form is 0.5

Answer:

28%

Step-by-step explanation:

Given that,

The total no of runners = 25

No. of boys in the team = 18

We need to find the percent of the track team are girls.

Total no of girls = 25-18 = 7

Percent of girls :

[tex]g=\dfrac{\text{No. of girls}}{\text{Total runners}}\times 100\\\\=\dfrac{7}{25}\times 100\\\\=28\%[/tex]

Hence, there are 28% of girls.

Answer: 30 students liked both.

step-by-step explanation: If there are 65 students and 10 liked math but not english you subtract 10 from 65, you get 55. You continue to the next one, 55-20= 35, now there are 35 students but 5 of those students don't like either, so 35-5=30, meaning there are 30 students that like both english and math. I hope this helps.

Answer:

157°

Step-by-step explanation:

(4x - 5)° = (x + 16)°.. (vertical angles)

4x - 5 = x + 16

4x - x = 16 + 5

3x = 21

x = 21/3

x = 7

(x + 16)° + y ° = 180°...(Linear pair angles)

(7 + 16)° + y° = 180°

23° + y° = 180°

y° = 180° - 23°

y° = 157°

Answer:

4 weeks

Step-by-step explanation:

Company A charges $40 per week and a one time fee of $25

Company B charges $35 per week and a one time fee of $45

Therefore the number of weeks required for both companies to arrive at the same cost can be calculated as follows

Company A = 45 + 35×4

= 45 + 140

= 185

Company B = 25 + 40×4

= 25 + 160

= 185

Hence it will cost both companies 4 weeks

78.151 (approximately)

Step-by-step explanation:

To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r²

=140/360×π×8²

=7/18×3.41×64

=7/18×157/50×64

=7/9×157/50×32

=7/9×157/25×16

=17584/225

=78.151 (approximately)

Answer:

C.) SAS

Step-by-step explanation:

When the marks on a triangle are the same as another, they have a congruent measure.

In the given triangles, the red line and arch on both mean they have a congruent side and angle.

Since they share a side, that side is congruent for both.

So now we have a congruent side, angle, and side. This is the SAS theorem,

[tex]-6-(-1)\\-6+1[/tex]

-(-1) = 1 as negative multiply negative equals positive.

Thus, the answer is -6+1 = -5.

The answer is the third choice, -5.

The point -5 1/4 is plotted on the number line in the graph as shown.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. A graph consists of some points and lines between them.

For the given situation,

The point is -5 1/4.

We need to plot this point on the number line shown.

In the graph below, the point -5 1/4 is plotted on the number line.

Hence we can conclude that the point -5 1/4 is plotted on the number line in the graph as shown.

Answer:

An inscribed angle is an angle formed by two chords in a circle which have a common endpoint. This common endpoint forms the vertex of the inscribed angle. The other two endpoints define what we call an intercepted arc on the circle. The intercepted arc might be thought of as the part of the circle which is "inside" the inscribed angle.

Answer:

$82 sundaes

$74 banana split

Step-by-step explanation:

Step one :

Given data

Cost of sundaes =$2 each

Cost of banana split =$3 each

Let the number of sundaes bought be x

And the number of banana split bought be y

The total is x+y

The shop sold 8 more Sundaes than the Banana split

x=8+y—-------1

Total amount made = $156

Therefore the system of equation for the situation is

x=8+y----—----------1

2x+3y=156---------2

But x=8+y

8+y+y=156

8+2y=156

2y=156-8

2y=148

Divide both sides by 2

y=148/2

y=74

On That day they sold $74 banana split

And also they sold x=8+74=$82 sundaes

Answer:

The answer is no solutions

Step-by-step explanation:

Let's solve your equation step-by-step.

x−3=x+3

Step 1: Subtract x from both sides.

x−3−x=x+3−x

−3=3

Step 2: Add 3 to both sides.

−3+3=3+3

0=6

Therefore, no solutions :)

The volume of the prism is 72

The height of the prism is 3 ft

The base of the prism is 24 square feet

The formula for volume of a prism is base multiplied by the height

Volume= base × height

= 3 × 24

= 72

Hence the volume of the prism is 72
