Answer:

101,929,0

Step-by-step explanation:

the answer is 1019290 on this math question

Step-by-step explanation:

the middle one.

S starts at 10 and then subtracts 1 with every step. that means it is going "backwards" from right to left.

T starts at 10 and then subtracts 2 with every step.

in combination the middle graphic follows both.

Step-by-step explanation:

Step 1 - Expand bracket:

[tex]-3(x - 14) + 9x = 6x + 42\\-3(x) + -3(-14) + 9x = 6x + 42\\-3x + 42 + 9x = 6x + 42[/tex]

Step 2 - Combine like terms:

[tex]-3x + 42 + 9x = 6x + 42\\42 + 6x = 6x + 42[/tex]

As both sides are the same, the equation equals 0.

[tex]42 + 6x = 6x + 42\\42 - 42 = 6x + 42 - 4x\\6x = 6x\\6x - 6x = 6x - 6x \\0 = 0\\[/tex]

Answer:

He will spend $32.76

Step-by-step explanation:

$7.92 * 2 kilograms = $15.84 (This is how much is spent on hamburger buns)

$8.46 * 2 kilograms = $16.92 (This is how much is spent on wheat rolls)

$15.84+$16.92 = $32.76 (This is the total amount spent)

Answer:

B. y = | x + 15.5 |

Step-by-step explanation:

The + inside the absolute value equation really means -.

So there is a horizontal shift of 15.5 units left.

Answer:

B. y = | x + 15.5 |

Step-by-step explanation:

Given : y= |x|.

To find : Write an equation for each translation of y= |x|. 15.5 units left .

Solution : We have given that y= |x|.

By the translation rule :if function transformed to  f(x ) →→→ f(x +h) Then graph of the function would shift h units left.

For translation 15.5 unit left we need to add 15.5 in function y= |x|.

y = | x + 15.5 |

Therefore, y = | x + 15.5 |.

Answer:

Jack traveled 5 miles in 1 hour

Step-by-step explanation:

Answer: In one hour Jack can Travel 5 miles.

Step-by-step explanation:

Jack can travel 20 miles in 4 hours. So to find out how many miles Jack can travel in 1 hour, we need to divide the number of miles for 4 hours (which is 20) by 4.

20 miles ÷ 4 hours  = 5 miles in 1 hour

Therefore, we can say Jack can travel 5 miles in 1 hour.

Answer:

The percentage rate per annum is 2.8%

Step-by-step explanation:

We need to multiply the principal by the time, then divide the interest by the product of P×T, so:

1,600 × 5 = 8,000

224 ÷ 8,000 = 0.028

Then we convert our final product to a percentage.

0.028 to a percent is 2.8%

X >/ -4 Means that the number is "true" as long as it is -4, or larger in amount.

Answer:

x=6.54138

x=0.458619

Step-by-step explanation:

using the Quadratic Formula where

a = 1, b = -7, and c = 3

x=−b±[tex]\sqrt{b^{2} -4ac}[/tex]/2a

x=−(−7)±√[(−7)2−4(1)(3)]/2(2)

x=7±√(49−12)/2

x=7±√37/2

The discriminant b2−4ac>0

so, there are two real roots.

Cannot Simplify the Radical:

x=[tex]\frac{7+-\\\sqrt{37} }{2}[/tex]

which becomes

x=6.54138

x=0.458619

The bar diagram is attached below. As we can see, the price of a yellow T-shirt is as three times as the price of a blue T-shirt. Hence, we can construct the following equation to determine the ratio between both prices:

[tex]y = r\cdot x[/tex] (1)

Where:

If we know that [tex]x = 8[/tex] and [tex]y = 24[/tex], then the price ratio is:

[tex]r = \frac{y}{x}[/tex]

[tex]r = 3[/tex]

The price of the yellow T-shirt is as three times as the price of the blue T-shirt.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

the graph has 2 x intercepts, which means there are 2 zeros, 4 and 5.

So we can express the function using:

[tex]y= (x-4)(x-5)[/tex]

this is equivalent to option A

Answer:

Step-by-step explanation:

Note that |-x| = 1, just as |x| = 1.  Removing the absolute value operator in both cases, we get x = 1.   In two dimensions the graph would be a solid dot at  = 1.

Answer:

simple convert to improper to subtract

51/4 turn to a common denominator

so multiply by 3

153/12. 4/12

then just divide 153 by 12 = 12.75* 3 bc 3 costumes are one yard and you get 38.25 costumes or 38 bc you cant have .25 of a costume

The no. of costumes Martin can make is 38.

It is given that 1/3 yards of Ribbon is needed for each costume and [tex]12\frac{3}{4}[/tex] yards of Ribbon is left.

We have to find out the no. of costumes which Martin can make.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations and the symbols are called variables.

As per the question ;

Ribbon needed for each costume = 1/3 yards

Ribbon left = [tex]12\frac{3}{4}[/tex] yards

Let's assume no. of costumes Martin can make is x.

The ribbon needed for x costumes will be ;

= [tex]\frac{1}{3}[/tex] × x

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

So ;

The no. of costumes will be ;

[tex]\frac{x}{3}[/tex] yards =  [tex]12\frac{3}{4}[/tex] yards

[tex]\frac{x}{3}[/tex] yards = [tex]\frac{51}{4}[/tex] yards

or

4x = 51 × 3

or

x = [tex]\frac{51 * 3}{4}[/tex]

x = [tex]\frac{153}{4}[/tex]

or

x ≈ 38

Thus , the no. of costumes Martin can make is 38.
