Ten less than three times a number is 2.

Answer:

16m+1

Step-by-step explanation:

Knowing about our proprieties about parentheses and negatives, let's solve this out.

A negative multiplied by a negative give you a positive

therefore....

-(-16m-1)= 16m+1

The -1 also receives the negative because the problem was in a parentheses :)

Answer:

10 servings

Step-by-step explanation

7 cups is equal to 21/3 cups. Since 21 isnt divisible by 2, you have to round down to the nearest divisible number, which would be 20. 20/2 is 10, so 10 is the answer.

A

Step-by-step explanation:

0 is sea lvl so just add and subsubtract

Answer:

A

2x-16

Step-by-step explanation:

By using the distributive property, you will get 2x-2(8).

Then simply the expression, which you would get 2x-16.

Answer: 2000m

Step-by-step explanation:

1km = 1000 m

1000 + 571 = 1571m

2000m > 1571m

Answer:

the green line

Step-by-step explanation:

its closest to the point

Hi there! The answer would be the green line and the dark blue line which is f(x)=2x+3 and h(x)=-2x+2.

Step By Step:

So you need to figure out the line for (2,-2).

This means that you would have to find a line that is between them which is the correct answer.

Well it can’t be orange since that it didn’t touch it and so can it not be red. So we have two answers left to choose from.

The last two pairs we have left would be the answer since they’re nothing touching the point for (2,-2).

This means that it would be D, dark blue and orange, or we can say f(x)=2x+3 and h(x)=-2x+2.

Answer:

Isosceles triangle

Step-by-step explanation:

The given sides of a triangle are 8 cm, 5 cm and 8 cm.

We need to say that the type of triangle.

The two sides of a triangle are same i.e. 8 cm and the other side is 5 cm.

Such type of triangle in which two sides are equal, the triangle is isosceles. Here, two sides are 8 cm and the third one is 5 cm. It means the triangle is an isosceles triangle.

Answer:

4/9 to 5/9

Step-by-step explanation:

So, out of every 9 students, 4 are boys. Therefore, 4/9 of the students are boys. The ratio of boys to girls is 4:5. So let 4x be the number of boys and 5x be the number of girls.

Answer:

15

Step-by-step explanation:

Fiona (F) = Sushi (S)

Malachy (M) = 7 Fiona (F)

M = F + 90

F + 90 = 7F

6F = 90

F (Fiona) = 15

S (Sushi) = 15

check: Malachy (M) = 15 * 7 = 105

M-F = 105 - 15 = 90

Answer:

Answer:

-0.75

Step-by-step explanation:

To get the z score we have to use this formula

Z = X-mean/standard deviation

X = 2300

Mean = 3200

The standard deviation = 1200

When we plug these values into the z formula above, we have:

2300-3200/1200

= -900/1200

= -0.75

the z-score for a backyard structure costing $2,300 is therefore -0.75

Answer: 504 hours.

Step-by-step explanation: I am assuming it says, use a table not a lable.

Well, I can't make a table, so I will tell you where to put everything in a table.

We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.

24 x 7 = 168 and 1 x 7 = 7

So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by  the 3 weeks. So we multiply 168 by 3 which is 504.

So 504 hours are in 3 weeks.

Answer:

A

Step-by-step explanation:

The two triangles are congruent because if each triangle's angles add up 180 degrees, you can deduce that the triangles have atleast two congruent angles.

Triangle RST:

48 + 73 = 121

180 - 121 = 59

Angle R = 59

Angle T = 48

Angle S = 73

59 + 48 + 73 = 180

Triangle ABC:

73 + 59 = 132

180 - 132 = 48

Angle A = 59

Angle B = 73

Angle C = 48

59 + 48 + 73 = 180

Answer:

x = 8

Step-by-step explanation:

You distribute the 3 to x and -4.

[tex]3x-12=12[/tex]

You add 12 to both sides.

[tex]3x=24[/tex]

Then you divide by three on both sides.

[tex]\frac{3x}{3}=\frac{24}{3}\\[/tex]

[tex]x=8[/tex]

Answer:

30

Step-by-step explanation:

discounting by 20% is the same as marking to 80% of the original cost. 80% = .8

set up equation and solve

.8x=24

x=30

Answer:

x=1/6 or x=0.1666666667

Step-by-step explanation:

Answer: x=32

Step-by-step explanation:

Because a triangle is 180°, the missing angle in the triangle would be 60°.

Because of the 30°-60°-90° angles theorem, The side opposite 90° is double the side opposite 30°, which means that x=32.
