Answer: D $26

Step-by-step explanation:

50-(50x.3)= 35

35-6=29

29-3=26

Answer:

5 - 3 = 2

2x =2

x = 2x ÷ 2 = 1

Answer is 1

Answer:

5=2x-3

collect like terms

if -3 crosses the equal to sign it will change to +3

5+3=2x

8=2x

divide both sides by 2

X=4

Answer:

8 < x <22

Step-by-step explanation:

In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x

One one side of the inequality we have:

7+15>x

22 > x

On the other side we have

7 + x > 15

X > 15-7

X>8

When we rearrange these inequalities above we have

8<X<22

We saw from the calculations that 8 is less than X and X is less than 22.

Answer:

Answer:

2 hours 48 minutes

Step-by-step explanation:

Debra=1 plowing job / 7 hours

Debra+Alexandra=1 plowing job / 2 hours

1/2-1/7

=7/14-2/14

=5/14

=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)

14/5 hour=2 hours 48 minutes (hope hits helps)

Alexandria to finish the same job alone in, 2 hours 48 minutes

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Debra and Alexandria can finish a plowing job in two hours if they work together.

And, Debra can do the job in 7 hours by herself.

Hence, We get;

For Debra = 1 plowing job / 7 hours

Debra + Alexandra = 1 plowing job / 2 hours

Hence, Time to take Alexandria to finish the same job alone is,

= 1/2 - 1/7

= 7/14 - 2/14

= 5/14

= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)

= 2 hours 48 minutes

Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

Step-by-step explanation:

Sample space for the sum of 2 spins :

Number on spinner = 2, 5, 4

____ 2 ___ 5 _____4

2___ 4 ___ 7 _____ 6

|

5___ 7 ___ 10 ____ 9

|

4___ 6 ___ 9 ____ 8

Hence,

(4, 7, 6, 7, 10, 9, 6, 9, 8)

Probability of getting a sum less than or equal to 8;

Probability = required outcome / Total possible outcomes

Required outcome =, sum ≤ 8 = 6

Total possible outcomes = 9

P(sum ≤ 8) = 6/9 = 2/3

Answer: C. (2, -4)

Answer:

Sally is 23 years old.

Step-by-step explanation:

John's age is completely unknown, so it is known as x

Meanwhile, Sally's age can be represented as 3x+2

The sum of both ages is 30.

So, x+3x+2=30

Combine like terms.

4x+2=30

Subtract 2 from both sides.

4x=28

Divide both sides by 4.

x=7

John is 7 years old.

Sally's age: 3(7)+2=23

Sally is 23 years old.

I have attached the complete question with the triangle.

Answer:

x = 6

Step-by-step explanation:

From the image attached we are told to find x in the triangle.

The triangle is a right angle triangle and so we can use pythagoras theorem to find x.

x² = 6.5² - 2.5²

x² = 42.25 - 6.25

x = √36

x = 6

Answer:

No, because x has multiple values for y.

Step-by-step explanation:

Any input into a function has to map into exactly one output. The input, x, has multiple values for y. Therefore, it is not a function.

Answer:

x = 10

TU = 24

Step-by-step explanation:

To find the value of x, we use the trapezoid mid-segment theorem

The sum of the lengths of the two parallel sides is equal to twice the length of the mid segment

Mathematically, we have this as;

2(2x+ 4) = 2x-4 + 3x + 2

4x + 8 = 5x - 2

5x -4x = 8 + 2

x = 10

TU = 2x + 4 ; = 2(10) + 4 = 20 + 4 = 24

Answer:

S = 73.5 unit³

Step-by-step explanation:

[tex]A_{s} = 6e^{2}[/tex]

[tex]A_{s} = 6 (3.5)^{2}[/tex]

[tex]A_{s} = 6 (12.25)[/tex]

[tex]A_{s} = 73.5[/tex]

Answer:

73.5 unit^2.

Step-by-step explanation:

Area =  e^2

Area of one face = 3.5^2 = 12.25 unit^2.

So total surface area = 6 * 12.25

= 73.5 unit^2.

The slope is 0.6

Answer: What number, when added to negative four is equal to negative five.

Step-by-step explanation:

Rearange the numbers to get -4+g=-5.

This eqation now reads -4 plus a number g is equal to -5, and can also be read as what number (g) added to -4 = -5.

If we were to solve for g we would get g= -1.

Answer:

the third option, "what number, when added to negative four, is equal to negative five?"

Explanation:

"what number, when added to negative four, is equal to negative five?" can be expressed as g + (- 4) = - 5, which is the same as in the equation.
