Answer:

Tommy's band won 5 awards, Ali's band won 8 awards and Jack's band won 10 awards.

Step-by-step explanation:

Let the number of awards Tommy won be x.

Number of awards Ali won -> x+3

Number of awards Jack won -> 2x

[tex]x+x+3+2x=23[/tex]

[tex]4x+3=23[/tex]

Subtract 3 from both sides:

[tex]4x+3-3=23-3[/tex]

[tex]4x=20[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{20}{4}[/tex]

[tex]x=5[/tex] (Tommy)

[tex]5+3=8[/tex] (Ali)

[tex]5\times2=10[/tex] (Jack)

Answer: Tommy won 5 awards. Ali won 8 awards. Jack won 10 awards.

Step-by-step explanation:

First give each person a variable:

Tommy = y

Ali = a

Jack = x

Then figure out the equations:

Tommy won 3 less awards than Ali, so the equation would be (y = a - 3).

Jack won twice as many awards as Tommy, so the equation would be (x = 2y)

All three won a total of 23, so that would be (23 = y + x + a)

Next, plug in (2y) into the (x) of (23 = y + x + a)

This would result in (23 = 3y + a)

Then you would plug in (a - 3) into (y)

This would result in (23 = 4a - 9)

Solve for a: (a = 8)

Now that you know (a = 8), plug that into the first equation (y = a - 3) to find (y).

Answer: (y = 5)

Use (y = 5) and plug it into the second equation (x = 2y) to find (x)

Answer: (x = 10)

1 d.p:

4.03834 = 4.0

24.8845 = 24.9

0.62346 = 0.6

2.3999 = 2.4

The 1 d.p is the first number after the decimal point and to write it as 1 d.p you need to round it off.

2 d.p:

4. 03834 = 4.04

24.8845 = 24.88

0.62346 = 0.62

2.3999 = 2.40

The 2 d.p is the second number after the decimal point.

3 d.p:

4.03834 = 4.038

24.8845 = 24.885

0.62346 = 0.623

2.3999 = 2.400

The 3 d.p is the third number after the decimal point.

Answer:

Distance

Step-by-step explanation:

To find:

Which of the following options is an equation.

Solution:

A mathematics or algebraic statement which represents that the values of two mathematical expressions are equal, is called an equation.

In option A,

[tex]5-4=9[/tex]

[tex]1\neq 9[/tex]

LHS≠RHS. So, it is not an equation.

In option B and C,

[tex]5+4=9[/tex]

[tex]9=9[/tex]

LHS=RHS. Both are equations.

In option D,

[tex]5+4-9[/tex]

This is an expression, not an equations.

Therefore, the correct options are B and C.

Let's add all the values on one side and make it equal to the sum of all the other values on the other side

(- X) + (- X) + (- X) + (- X) + (- X) + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1  =  X + X + X + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1)

- 5X + 12 = 3X - 8

- 5X - 3X = - 8 - 12

- 8X = - 20    x(- 1)

8X = 20

X = 20/8

or X = 2.5

Answer:

x = -11

Step-by-step explanation:

First, get rid of parentheses:

5 + x - 2 = -8

Then, simplify:

3 + x = -8

Finally, subtract 3 on both sides:

x = -11

Hope this helps ^^

Answer:

x = -11

Step-by-step explanation:

5+(x-2)=-8

3+x = -8

Subtract 3 from each side

3+x-3 = -8-3

x = -11

y = x+5 where y is Mark's age

Step-by-step explanation:

Hi there, to answer this problem, you need to really think about what it is asking. In saying that mark is 5 years older than Juan, we know it is going to involve addition. Then, you simply need to think about the relation to Juan's age. In this case, Mark is older so you add to it. Hope this helped!

The answer should be 10p - 4.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given expression is,

3p + 5 + 7p - 9

To solve this taking alike terms together.

3p + 7p + 5 - 9

Thus, we have

Variables = 3p + 7p = 10p

Constants =  5 - 9 = -4

Thus, the expression becomes,

3p + 5 + 7p - 9 = 10p - 4

So, this is the required answer of the given expression.

Thus, the answer should be 10p - 4.

Area of the border = Length * Breadth

If the outside measures 10in by 11in with 1-in border, the length of the picture with border = 10+(1+1) * 11+(1+1)

Area of the border = 12*13

Area of the border = 156in²

Answer:

y-intercept and slope

Step-by-step explanation:

When we graph a line using slope and y-intercept, the first point that you graph is  y-intercept.

What is Mathematical equation ?

By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.

So, When we graph a line using slope and y-intercept, the first point that you graph is  y-intercept.

Let, consider the equation of y = mx+c, where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.

Therefore, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.

Answer:

[tex]\frac{3}{16}[/tex]

Step-by-step explanation:

We do the division first because of PEMDAS.

Apply the fraction division rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]

Therefore,

[tex]\frac{5}{8}-\frac{1}{4}\div \frac{4}{7}=\frac{5}{8}-\frac{1}{4}\times \frac{7}{4}[/tex]

Multiply the two fractions:

[tex]\frac{5}{8} -\frac{1\times \:7}{4\times \:4}[/tex]

[tex]\frac{5}{8}-\frac{7}{16}[/tex]

The LCM of the denominators (8 and 16) is 16.

Adjust fractions:
