What is (3 x 20) + 9 and what is (4 x 100) + 20?

Answer:

17

Step-by-step explanation:

divide by 5 both side and q will be:

q-2=15 then take 2 to the other side which will be positive . therefore

q=17

The sandwich will cost $3.1.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Let's say the cost of 1 drink is d while the cost of 1 sandwich is s

Now,

Given that,

A drink and a sandwich together cost $4.85.

So,

s + d = 4.85

And,

The sandwich cost $1.35 more than the drink.

So,

s = 1.35 + d

By using substitution

s = 1.35 + 4.85 - s

2s = 6.2

s = 3.1

Hence "The sandwich will cost $3.1".

Answer:

428

Step-by-step explanation:

Its says out of 60, 29 of them play sports

so we want to use proportions to solve for how many would play if there were 887 kids

[tex]\frac{60}{29} =2.068965517\\\frac{887}{2.068965517} = 428[/tex]

thus meaning that out of 887 kids 428 of them would play sports

Answer:

[tex]y=\frac{13}{6}x[/tex]             [tex]y= \frac{11}{5}x[/tex]          [tex]y = \frac{21}{9}x[/tex]          [tex]y = \frac{19}{8}x[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Equations with higher unit rate

First, calculate the unit rate of the graph

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where:

[tex](x_1.y_1) = (0,0)[/tex]

[tex](x_2.y_2) = (7,15)[/tex]

So:

[tex]m = \frac{15 - 0}{7 - 0}[/tex]

[tex]m = \frac{15}{7}[/tex]

[tex]m = 2.143[/tex]

For the given options.

The unit rate is the coefficient of x

So: [tex]y = \frac{19}{8}x[/tex]

Going by the above definition of unit rate.

[tex]m = \frac{19}{8}[/tex]

[tex]m = 2.375[/tex]

[tex]y = \frac{27}{13}x[/tex]

[tex]m = \frac{27}{13}[/tex]

[tex]m = 2.077[/tex]

[tex]y = \frac{21}{9}x[/tex]

[tex]m = \frac{21}{9}[/tex]

[tex]m = 2.333[/tex]

[tex]y= \frac{11}{5}x[/tex]

[tex]m= \frac{11}{5}[/tex]

[tex]m= 2.20[/tex]

[tex]y = \frac{15}{7}x[/tex]

[tex]m = \frac{15}{7}[/tex]

[tex]m = 2.143[/tex]

[tex]y = \frac{31}{15}x[/tex]

[tex]m = \frac{31}{15}[/tex]

[tex]y = 2.067[/tex]

[tex]y=\frac{13}{6}x[/tex]

[tex]m=\frac{13}{6}[/tex]

[tex]m=2.167[/tex]

The unit rates grater than the graph's from small to large are:

[tex]y=\frac{13}{6}x[/tex]             [tex]y= \frac{11}{5}x[/tex]          [tex]y = \frac{21}{9}x[/tex]          [tex]y = \frac{19}{8}x[/tex]

[tex]m=\frac{13}{6}[/tex]              [tex]m= \frac{11}{5}[/tex]           [tex]m = \frac{21}{9}[/tex]            [tex]m = \frac{19}{8}[/tex]

Answer:

y = 25

Step-by-step explanation:

180 - 115 = x

x = 65

x + 90 + y = 180

65 + 90 + y = 180

y + 155 = 180

y = 25

Answer:

[tex]\huge\boxed{\sf Solution\ Set = \{x,y\} = \{1,2\}}[/tex]

Step-by-step explanation:

3x + 4y = 11 ----------------------(1)

x = 15 - 7y   ----------------------(2)

Put Eq. (2) in (1)

3(15 - 7y) + 4y = 11

45 - 21y + 4y = 11

45 - 17y = 11

Subtracting 45 to bot sides

-17y = 11 - 45

-17y = -34

Dividing both sides by -17

y = -34 / -17

y = 2

[tex]\rule[225]{225}{2}[/tex]

Put y = 2 in Eq. (2)

x = 15 - 7(2)

x = 15 - 14

x = 1

[tex]\rule[225]{225}{2}[/tex]

Solution Set = {x,y} = {1,2}

[tex]\rule[225]{225}{2}[/tex]

Answer:

P=78,56 If something is not clear to you, just ask, I will be happy to help :)

Step-by-step explanation:

To calculate the total area of a figure, you divide it into several shapes.

P1, P2, and P3 are the area of the rectangle, P4 is the area of the square, and P5 is the area of one-quarter of the circle.

P1=a*b

P1=8*6

P1=48

P2=a*b

P2=3*2

P2=6

P3=a*b

P3=4*2

P3=8

P4=[tex]a^{2}[/tex]

P4=[tex]2^{2}[/tex]

P4=4

P5=[tex]\frac{1}{4} * r^{2} *\pi[/tex]

P5 = [tex]\frac{1}{4} * 4^{2} * \pi[/tex]

P5 =4[tex]\pi[/tex] or approximately 12,56

P = P1+P2+P3+P4+P5

P = 48+6+8+4+12,56

P=78,56

Answer:

[tex]\dfrac{18(3\sqrt2-1)}{17}[/tex]

Step-by-step explanation:

The given expression is :

[tex]x=\dfrac{18}{3\sqrt2+1}[/tex]

We need to rationalize the denominator.

Multiplying and dividing both sides by [tex]3\sqrt2+1[/tex] as follows :

[tex]x=\dfrac{18}{3\sqrt2+1}\times \dfrac{3\sqrt2-1}{3\sqrt2-1}\\\\=\dfrac{18(3\sqrt2-1)}{(3\sqrt2)^2-1}\\\\=\dfrac{18(3\sqrt2-1)}{(18-1}\\\\=\dfrac{18(3\sqrt2-1)}{17}[/tex]

So, the answer is [tex]\dfrac{18(3\sqrt2-1)}{17}[/tex].
